Just doing a bit of reading on http://www.malvernracing.com/php-bin/phorum/read.php?f=3&i=70&t=1&v=f and noticed that Dave Weber of Malvern Racing mentioned that all the L series, Z series and KA series all share the same clutch ring gear diameter, crank 6 bolt pattern, thus all the flywheels are interchangable between the motors.

He also mentioned the different clutch sizes: 200mm, 225mm, and 240mm. The 200mm clutch/flywheel is the lightest package of them all, making it a good option for roadracers seeking response.

The 225mm is the standard size for the KA.

The 240mm is used on the later 280ZX Turbos for much more holding power. This is a possible solution for the KA+T folks looking for more holding power.

Now the hard part: Actually spending the cash to get a 240mm flywheel/clutch combo and test it out on a KA to make sure the tranny bellhousing is large enough to clear the package.

Once this is tested, it will simplify the search for the holy clutch. This would negate the solution JWT was seeking where the 240mm clutch from a Z32 was fitted to the KA flywheel. Instead, can just go pickup the Nissan motorsport catalog and order a 280ZX Turbo clutch and flywheel for much lower price.

Now, this raises another question, what is the ring gear diameter and crank/6 bolt pattern for the SR flywheel? Someone with access to such information, please compare it to a KA's info, just for grins. Curious minds would like to know.

hmm, after some more digging around, seems like the '91+ D21 pickups are using the 240mm clutch with it's KA24E. Now I wished I didn't toss away the old flywheel and clutch from my truck aswell as my friend's used S14 clutch. Would've been interesting.

And there is a Tilton aluminum flywheel available, that weights 11lbs, that accepts the 240mm clutch. At $360, it's cheaper than the Jun or any lightweight flywheel with more potential holding power and racing reputation.

yup, the trucks clutch is the bigger one. you can use it but youd have to get the flywheel too.

Chris May is running the JWT setup, Z32 NA clutch upgrade. It's so aggressive the pressure plate was worn down way before the disc. I'd rather have something a little less expensive to replace too.

Well, if this works out, then we have a cheaper replacement clutch. Digging around somemore on ACT's website, and noted the torque capability of the 280ZX Turbo clutch is at 400ft-lb, which is heck a lot more than the 267ft-lb for the 225mm unit for the 240SX.

Russ,

Is Chris running a modified KA flywheel that accepts the 240mm Z32 NA clutch?

TY.... instead of the 280ZX turbo clutch, we have historically used the Roadster clutch in our L series applications (street use) as they have the most gripping power of all the Nissan OEM clutches for the L/Z series motors.

The 280SX turbo clutch is 245 mm, but wimpy in holding power. I used the Roadster clutch in my 200SX with the 11.5:1 street motor Andy built for me back in the late 80's, and it held great for a street clutch.

NOT sure how the Roadster clutch compares to the 240SX clutch or aftermarket ones like the DF, or ACT.

<HR></BLOCKQUOTE>

Yes TY,
The stock fly wheel was mmodified to acccept the 300ZX N/A Pressure plate bolt pattern. When I was looking for a clutch Chris told me of this. The only big concern is what ever machine shop drills the bolt pattern for the Z pressure plate must get it centered. Otherwise, you will have vibration problem if it is not centered.
For that reason I just bought a JWT clutch package.

TY are you starting to have slipping problems with your clutch?

I haven't had any problems with mine yet. I drag race launching at 4-5 grand on drag radials and even MT ET slicks before and haven't had a slipping problem.

Don,

You should try using the roadster clutch on your S13. The flywheel's ring gear should be the same diameter, as well as the 6 bolt crank pattern.

The goal behind this investigation is to open up the aftermarket clutch opportunity for the KA motor. Only clutches on the market right now is the 225mm clutch which leaves more to be desired in the torque capability. I know it's possible to go to a pucked setup for more holding power, but that is at an expense of streetability.

Once the 240mm clutch gets tested and proven to work, even the most basic street clutch setup is far better than the capacity of the 225mm clutch. Not to metion those trick Tilton multiplate clutches.

So, once that's settled, KA folks don't have to look with envy at those multiplate clutches available for the SR, when a high quality Tilton multiplate race clutch could be purchased at a slight price advantage. This further opens the door for future high powered KA folks.

Personally, I would like more holding power than what my 225mm ACT clutch provides right now at 267ft-lb of torque. When I try to feather the clutch during hard drag launches, I basically toast the disk, causing it to slip through all 5 gears. It's tempting to get a pucked disk, but it's a street car. The 240mm ACT clutch's holding power is at 400ft-lb. Much better, and more suited for my motor's need. And if I need more, the pucked disk setup for the 240mm clutch is over 500ft-lb. More than plenty.

'97 S14 SE Turbo
12-26-2001, 10:06 AM
I've always babied the clutch since I know it's the weakest link in my setup. Having put down 329ft-lb of torque at 4,300, one can see how much margin is left for me with the clutch. I have to let the clutch grip first before I even load up on the throttle.

It's fine for opentrack events I do, but it's just pretty bad at the drag strip. Can never launch hard or risk toasting the disk.

Then my question to you is:

Which setup would you recommend for the KA as far as clutch/flywheel setups are concerned? Mike Kojima and I are looking for a lightweight flywheel and clutch setup to dyno-test...

-alex

'97 S14 SE Turbo
12-26-2001, 11:37 AM
See if Kojima could get his hands on a 200mm clutch/flywheel combo and install it on your car. That would have the lowest rotating inertia of all the other clutch out there besides the crazy multiplate racing clutch. Oh yeah, ask him to get you a Tilton aluminum flywheel. The 200mm cover is cheap @ $61 on www.nismoparts.com. (http://www.nismoparts.com.) The disk is expensive at over $200.

TY, I have an extra stock flywheel laying around in my garage from one of my many KA motors.

'97 S14 SE Turbo
12-26-2001, 07:01 PM
Measured up a KA bellhousing as well as a SR bellhousing.

Looks like there are plenty of room in the KA's bellhousing to accomodate the 240mm clutch.

As for the length issue between an SR and KA tranny, none. Both are the same casing.

So, looks like I've narrowed down the candidate for my future clutch upgrade.

Sounds great! I am surprised JWT never picked up on this. Find out for sure for us, TY, so we can get it! Sounds like a great upgrade...50% more holding power than ACT 240SX clutch, with same streetability.

Alright, found a junkyard with a '83 280ZX Turbo flywheel and clutch. Will go by to pick it up later today... I already have a KA flywheel/engine/transmission/starter to test everything together.

'97 S14 SE Turbo
12-28-2001, 10:20 PM
Got the 280ZX Turbo flywheel.

At first glance, noticed that the flywheel is the same diameter.

The contact patch is about .5" larger in diameter.

I'll get the KA flywheel off tomorrow and compare the 280ZX Turbo flywheel back to back for the # of teeth on the ring gear, and compare the overall diameter.

So far, it's very, VERY, promising that the 280ZX Turbo flywheel/clutch will work. Once I get the flywheel compared, I'll be ordering the 11lb Tilton Flywheel and 280ZX Turbo ACT clutch with it's 400ft-lb torque capability... http://www.freshalloy.com/ http://www.freshalloy.com/ http://www.freshalloy.com/ http://www.freshalloy.com/ http://www.freshalloy.com/ http://www.freshalloy.com/ http://www.freshalloy.com/ http://www.freshalloy.com/

Whats the torque capacity of the 200mm ACT unit, would you happen to know off-hand?

'97 S14 SE Turbo
12-28-2001, 10:43 PM
ACT doesn't have an application for the 200mm clutch.

I'll dig up my Nissan Motorsport catalog to see if they have a torque spec for that clutch.

**DONOTDELETE**
12-28-2001, 10:49 PM
So does the 200mm bolt up to the OE flywheel? I'd like to try that just for the weight issue, but it's even better if it's more responsive. Cool.

'97 S14 SE Turbo
12-28-2001, 10:50 PM
Nope, you will have to buy the flywheel that corresponds to the 200mm clutch. Same goes for the 240mm clutch.

Take a look at www.nismoparts.com (http://www.nismoparts.com) and under 510, 610, 710, etc clutch assy. You will see the different clutch/flywheel sizes.

But don't do anything yet until I get it tested.

Man, please let us know. T.Y. I know understand what you mean about the aftermarket clutches http://www.freshalloy.com/

I just fried my clutch lastnight. I dropped my exhaust, put 116 race fuel in the car, and installed my LSD in the car. I ran a 8.3 in the 1/8 mile at 10psi. An RX7 ran a 8 flat. So I turned the boost up since I was running race fuel. I launched at 4,500RPM and absolutely fried the clutch. I could run anymore lastnight, and the clutch disk is really acting up. I just got that dam clutch about 7 months ago and its already gone. http://www.freshalloy.com/

I wonder if a ACT disk will hold up better?
T.Y. I'll wait for your results first I think.

Thanks for the helpful info man!!!!!

Bad news,

Hit a snag in the project.

The good news:

1) Ring gear and # of teeth is exactly the same.

2) Bolt size and pattern is exactly the same.

The bad news:

1)The center bore of the 280ZX Turbo flywheel is smaller, requiring it to be machined to KA size before being able to install it.

2) KA crank uses a small brass pin to key the flywheel, and the 280ZX Turbo flywheel doesn't have this feature. Can easily break of brass pin from KA crank to use.

3) Spacing from back of flywheel where it mates with crank is different. 280ZX Turbo flywheel clutch face is about 7/8" and the KA flywhee clutch face is about 1.1". Even though the spacing is not the same, this may and may not be bad news.

Plan of action:

Will call up Nissan Motorsport on Wednesday when they open back up. See if they have any pull to get a series of 240mm clutch KA flywheels made and available or to get contact information for different aftermarket flywheel manufacturers.

'97 S14 SE Turbo

Not yet, I was going to talk to the folks at Nissan Motorsport to find out more information on it. Now it seems like I'll find out where they get their KA flywheels from and contact the manufacturer to see if they could do a series of 240mm flywheels.

These are all the 240mm clutch disk setup. The disk and pressure plate can be the same, but the flywheel can definetly be very different due to different starter placement, etc.

The trick now is to get an aftermarket flywheel manufacturer to offer up a limited production run for a group buy, or a business like Nissan Motorsport to buy a set.

But, before going down that path, the solution may be as simple as I've put it where the bore gets machined, key hole for the brass pin drilled and ignore the spacing difference.

Or worse case scenario, run an automatic transmission flex wheel with a Tilton Button multidisk clutch pack mounted to it! http://www.freshalloy.com/ http://www.freshalloy.com/ http://www.freshalloy.com/ http://www.freshalloy.com/

Yeah...just by hunting around for info on aftermarket 300ZX and 280zx flywheels, looks like they're different.

Interestingly enough, it seems (to me) that all the aftermarket flywheels for the 280ZX don't differentiate between the turbo and non-turbo -- perhaps they just put a 240mm friction surface on it and if some of it isn't used with a smaller clutch, then no biggie I guess?

Hmmm...check with Fidanza -- I've heard nothing but good things about their flywheels, and they have a replaceable friction surface, and an OEM steel ring gear shrunk-fit onto the flywheel. Prices seem pretty reasonable too, from what I've seen around.

You may want to get in touch with Malvern Racing and see what their thoughts are on the L-series flywheel on the KA -- if they've ever done the swap, they'll know about the differences. Seems like the most pressing (har har) issue is the spacing -- i.e. whether or not it matters. If I understand you correctly, if you put the 280ZX flywheel on a KA, it'll be about 1/4" closer to the block than the KA flywheel? Perhaps that extra distance will just be taken up by moving the release bearing and sleeve by that amount, and then adjusting the clutch pedal so it engages correctly?

well, I just got off the phone with RaceTep i.e. Top End Performance . The will balance ,surface and lighten the steel truck flywheel for me for $150. This is getting more exciting by the moment. This is a very affordable way to go for those of us who want lightened flywheels but don't want to spend the $300+ a Fidanza would cost. they will be taking off somewhere between 8-10lbs from the steel flywheel which seems to be a nice comprimise.
Anyways I am off to pick up a truck flywheel and start checking up on the clutchs . thanks again T.Y. for getting me going on this.

Well, they were the first people I called. I figured I would check with them first http://www.freshalloy.com/
Looks like I will be calling some other ones in the morning seeing as If I can get it done for $75-90. that will be great. I just picked up a 93 truck flywheel and yes it has the larger surface area and it is exactly the same overall size.

First off I am thinking of going to the yards and getting a 91 truck flywheel for the larger clutch surface. I will check in with top end performance to see if they can lighten the flywheel. I am also going to look at which clutch I can mate to this. I might as well put in a bigger clutch now because my turbo upgrade will happen sometime in the next 6 months or so.

As you may have read in another thread, I have recently installed a Fidanza lightweight flywheel on my KA-T. It weighs 11.2 lbs with the replaceable friction surface. None of the worrisome things I had heard about a lightweigh flywheel have (so far) been true.
There is no noticeable increase in engine or transmission noise, clutch engagement from stop and at low speed is really no different than stock, and I have no driveability problems. The pull in 1st, and 2nd not under boost is really improved and the onset of boost is seamless. The engine just spools right up to redline and the engine has lost a lot of its rough qualities at high rpm. This is one mod I wish I had done earlier.

Ok , I just may have found the Holy Grail http://www.freshalloy.com/ . OH by the way Demon, I checked with other machine shops and the price difference was like $50 . for the extra $50 I am going with Top End Performance seeing as they have experience with Nissan's since the 70's .
Anyways Its backside is exactly like the stock KA24DE flywheel so there is going to be no problems there.

the only thing I will have to do is get it drilled for the centering pin seeing as the KA24e in the truck did not have. Not a big deal really though.

Ok here comes the cool stuff . I did research Clutchs for the Truck . I was kinda suprised at what I found.
LUK a major manufacture of Automotive clutchs OE and aftermarket makes a heavy duty clutch for the truck . Its in their Goldline series. This Clutch comes as a complete kit for $150
It has 1,400 pounds of clamping pressure and can hold 500 lbs of torque that is almost double the ACT stage II clutch. Yes I am getting it . My flywheel will be done next week and I will let you guys know how it is.
I think this is a great setup for a KA24DET. thank you again TY for the idea your real world experience is invaluable.

I'll represent the N/A'ers and fire up some discussion on the 200mm clutch. http://www.freshalloy.com/

According to recent findings, LUK makes some pretty beefy clutches, plus it seems as if they have a 200mm application.(8"=200mm?)

Thus the '77-'81 200sx clutch would be the one to get? At ~$100 shipped this is a steal, plus it seems as if it is an optimal solution for lightweight. I will email the company and ask for the torques specs on this clutch and relay it.

My next question would be about the flywheel. Should an OE 200SX flywheel be lightened and balanced, or should an aftermarket solution be sought after (Tilton is the only 200mm light-weight flywheel producer or are there others)?

**DONOTDELETE**
01-05-2002, 08:57 AM
Keep looking into this. I'm not ready for a clutch yet, but when I am I'd like to go down a size and see what it's like. I'm sure I could sell my Stillen flywheel I have now to somebody.

OE replacements? (http://www.japanparts.it/japan/C2/C2NIS-01.htm), Beck Arnely (http://www.geocities.com/spl311rdst/parts/ba_partslist.html#clutch),...

I believe you might run into the same situation (as the 280ZX Turbo flywheel) where the center bore needs to be machined to a bigger diameter, and a spacer added to the face where the flywheel bolts to the crank to get the flywheel away from the oil pan.

Hmmm...I guess that the starter won't line up with the ring gear unless that spacer is there...

Hey guys....for the spacer that is needed, can we use the spacer that is used on the Automatic 240sx's. It's originally meant to be used on the other side of the flywheel but i thought it could be used as a spacer instead. What do you think guys. In the picture, it's on the lower right side of the diagram and numbered 12333, which is also Nissan part number 12333-42L00. I'm sure you can buy that piece for cheap...

Asad, This is the info Jim Crate got for me on this subject.
<BLOCKQUOTE><font size="1" face="Verdana, Arial[/img]quote:</font><HR>
From : Jim Crate &lt;omitted.com&gt;

To : T.Y. &lt;omitted.com&gt;

Subject : Re: 280ZX Turbo Flywheel

Date : Wed, 02 Jan 2002 10:20:30 -0500

T.Y., I thought a friend of mine in Miami had done something similar a few
years ago before flywheels were readily available for the 240SX, and had
mentioned that there was some machining that needed to be done. I asked him
about it to see if the info would help you. Here is what he did:

&gt; At the time an aluminum flywheel for the car was very expensive, around
&gt; $600 bucks. So my Nissan guys and I started talking. Turns out a 280ZX
&gt; Flywheel is almost a near fit. They both are 225 mm in diameter. Turbo
&gt; Nissans have flywheel diameters of 240 mm ( 280ZX Turbo, 300ZX Turbo, and
&gt; 300ZX Twin Turbo) . So it must come from a 280 ZX non- turbo. I believe
&gt; that earlier Z's have slightly smaller flywheels, I think.
&gt;
&gt; I got the 280ZX flywheel from Nissan Motorsports for around $300 from
&gt; Courtesy Nissan in Texas. Remember it is almost a perfect fit. We found a
&gt; 240sx crank that was laying around the shop and we had to make the flywheel
&gt; fit so we took it to a machine shop and they had to increase the center
&gt; hole diameter 1mm for it to fit on the crank. We new that we had to modify
&gt; it so that did not surprise us. When we installed it on the car is when we
&gt; had more problems, no big deal just minor fitment adjustments. The
&gt; flywheel was rubbing against the lip of the oil pan and the oil seal collar
&gt; on the block. We had the machine shop press in a 1/8th inch steel plate on
&gt; the flywheel. After that it went in without a problem. It has been
&gt; working fine for the past 4 1/2 years. Remember this particular flywheel
&gt; was ordered through Nissan Motorsports and it is manufactured by Tilton.
&gt; It weighed around 10.85 pounds compared to the stock at 21.4 pounds. It is
&gt; all aluminum except for the center disk that the clutch engages to. That
&gt; part is steel so that if you need to replace it you just order that part
&gt; from Tilton. I have the part # at home and it's around $80. A lot of
&gt; Aluminum flywheels today are completely made of aluminum, very light but
&gt; after it wears out you must spend major $ and buy a new flywheel. At the
&gt; time the total cost was about $425 for it. Now I know that they're are
&gt; several manufactures for it for a reasonable price $450-$500.

I guess you've already discovered most of this through your own research. I
don't know how different the turbo flywheels are, but it may not be too
difficult to make it fit.

Hope this helps,

Jim Crate<HR></BLOCKQUOTE>

I would assume a plate that has a OD that will fit the surface around the 6 bolt pattern. That would be the only sane place to put a spacer.

SR20DET (FR config) is a 8 bolt pattern flywheel with a 240mm clutch/pressure plate. Thus this info doesn't pertain to the SR.

FYI, The FWD/AWD config SR20DET uses a 215mm clutch/pressure plate.

So actually this spacer will be sandwiched betewwn the crank and the flywheel....i'm cool with that. Maybe it was just the way it was worded that threw me. I just wasn't following how he was "Pressing" it "ON" the flywheel.

So in short..this is really a sandwiching thing...right?

And if that's so, the the spacer in the picture i posted earlier would work then right?

Got a chance to talk with Sly at Nissan Motorsport.

He basically said not to worry about using a spacer. Get the center bore machined, and test fit the flywheel. Grind off offending part on crank seal. All should work out.

The alternative was to talk to Design Product, a company that Nissan Motorsport uses to make custom flywheel. They supply the KA flywheels for the S13/S14. They even built one for Sly to hold a dual plate Tilton clutch setup.

I've left a message with Design Product, and hopefully I'll be able to get pricing information on custom built flywheel.

I'm still a bit concerned about the ring gear meshing with the starter...although if the ring gear is wide enough, moving the flywheel a little bit should still allow for enough alignment of the starter to ring gear to allow it to work. How wide is the ring gear?

'97 S14 SE Turbo
01-07-2002, 04:57 PM
IIRC, a good solid 0.5"

From what I've gathered, before KA flywheels became available, the L series flywheel was used by numerous engine builders for the NASPORT racing series. He basically said, not to worry too much about it.

Personally, I would love to worry about it, hence checking pricing on custom built flywheel.

Oh, on the twin plate Tilton, the holding capacity is about 700ft-lb of torque!!! Single disk is 350ft-lb. Talk about some massive holding power with the two disk.

Ok! Good news!

Design Product of Huntington Beach, (714) 892-1513 has a 16v KA flywheel that takes the 240mm clutch/pressure plate. I just got off the phone, and I'm having one sent to me tomorrow.

Weight: Without the ring gear and steel friction surface. Guess what! 6lbs!! No kidding! With the ring gear and friction surface, should be around 8lbs. I'll find out when I get the flywheel.

Cost: Guess what? $375!!! That's a dang good deal for a lightweight flywheel from a company that has made flywheels for Tilton (race clutch manufacturer) and Nissan Motorsports.

So, I'll update when I get the flywheel and test it out!

01-08-2002, 02:02 PM

Ok for the guys who don't want to spend the big bucks . LIke I said earlier in this thread I picked up a 93 KA24e flywheel . I just got it back from Top End Performance. It was heaveir than the KA24DE flywheel stock due to the fact that it was made for the truck . It is now a 17.9 lb flywheel. A good wieght for a Turbo street performance machine IMHO and about 6-7 pounds lighter than the stock KA24DE flywheel. It goes into the car next monday along with the LUK goldline 240mm clutch . I will let you guys know as soon as I drive it how it feels .

They are still working on it. Expect to see final product next week, but unfortunately, I'm heading out of country for the next several weeks. By the time I see the final product, it will be in April.

I expect the vendor to do an exceptional job. The flywheel should be about 10lbs in weight with a replaceble friction surface.

What's taking so long is the revision the vendor had to make so that the flywheel is much more KA specific than a hybrid L28 flywheel.

<font size="2" face="Verdana, Arial[/img]You can change the tranny fluid...but it's easier to move the tranny when it's empty. Usually you just wait till the clutch change to change the fluid...drain the tranny before starting, remove tranny, replace clutch, replace tranny, then refill.

Flywheel is in... unfortunately, I'm half a planet away from it so I cannot take pictures of it...

If you are that desparate for pictures, call up Han at www.i-m-racing.com (http://www.i-m-racing.com) and ask him to post pictures of it on the shop's website.

It's a true to form KA24DE flywheel. The vendor information is already posted on the 1st page of this thread, and IIRC the phone number. It's $375, cheaper than the Jun KA flywheel, and takes the 240mm clutch vs the 225mm clutch for the Jun KA flywheel.

Weight: 10 lbs. It features a replaceble friction surface.

Looks: see statement above, but for the imaginative, just go dig up Tilton flywheel pictures from the web, and that's what it looks like... It's an all out flywheel that is more racing that street. I'll get to find out how much faster a KAT will spin with the crank, rods, and piston all balanced together.

And with this application everything fits fine? The bore is of proper size, it clears the pan, and has the keyhole?

What clutch are you planning on running with this application?

And lastly, is something like this streetable and acceptible for a daily driver/weekend racer?

I said they have a 240mm application. Didn't say it will be a direct fit for KA. It's a L series flywheel. The difference is in the back plate where it might potentially rub with the rear crank seal housing. That's the difference, and for the record, it was a brand new built disk, not a modified L series disk.

Early on, I got a L-series flywheel, but set it back, asking for a more specific application, which they complied with.

Key hole is no biggie. Jusk knock off the brass pin. The bore hole and the oil pan clearance was addressed. But again, like I said, I'm half a planet away from the flywheel, so I can't say too much about the specifics. I'm only talking about it from my specific request to the vendor.

Clutch? Whatever flirts my fancy... Ranging from Nismo (280ZX Turbo) to actual truck clutch (aka DPro)... I'll most likely end up using the ACT street clutch with it's 400ft-lb torque capacity. If I need a bit more at lesser price, there's a 500ft-lb truck clutch available... hehehe... Basically, any 240mm clutch application for Nissan is fair game, and that includes the NA Z32s...

If I need anything around 700ft-lb torque capacity, I will look into dual disk applications using street type disk. I hate the idea of driving around with copper pucked disk, just so the transmission can put down the power... Just not very streetable... (yes, dual or any multi-disk application is not streetable... only easier on the leg muscle.) The same vendor can build a Tilton clutch pack that is rated for 700ft-lb with even less rotating mass. The Tilton clutch pack is 200mm in diameter. Each disk is rated for 350ft-lb. 3 disk means 1050ft-lb torque capacity... (overkill). What's neat about the setup is that it uses the AT flex wheel, which is very light. And lot of those fancy JDM multiplate clutch is based on Tilton's setup. Another alternative is Clutch masters. They advertise that they can custom build multiplate clutches for the KA. Someone will have to find out...

As for the streetable part, well, as long as you are aware of a lightweight flywheel and adjust accordingly, no, it's not an issue... Just much tougher to drag-race launch without the kinetic energy stored in the flywheel. It is also without doubt that turbo spool up will suffer a bit due to reduced engine load during acceleration, but it's not an issue for someone who's aware of it.

update. Nothing yet. Waiting for the pressure plate so the flywheel can be balanced with the crank.

Once the balancing gets done, I'll get the flywheel installed on my current engine along with the ACT 280ZX Turbo clutch. Should be interesting...

Anyway, a quick and dirty guesstimation, the flywheel is about 9~10lbs. Pretty dang light. Makes me want to get an aluminum driveshaft to go with it too.

The V-6 flywheels definetly don't work for the KA application.

The pressure plate and flywheel might.

The biggest reason for sticking with the L28ET is that the L series engine is closely related to the KA and modified L-series flywheels have been used plenty of times on the KA. It's just the less painful approach. Just incase the pressure plate is too tall.
