200HP Natural Aspirated KA24DE

[**DONOTDELETE**]

Is it possible to make 200 horsepower out of the KA24DE without the help of any turbo, supercharge, or nitro? Maybe just some help from an intake, headers, exhaust, and some internal work on the engine. Also the KA24DE engine used inside that suppose to have been the new Z car. I remember reading an article about it making around 200HP. What did Nissan do to that KA24DE engine anyway?

I would think so. I mean its possible to get that much out of an NA SE-R and the KA24 motor puts out more horses and more torque than the SR20. I think an NA engine putting out at or around 200hp was what was used in the Z concept that was being shown around. Correct me if I'm wrong but I think thats what pissed off alot of Z enthusiasts because people didn't want the next Z to be a
4 banger because all other Z's had a 6 either straight 6 or V6. You'd probably have to put higher compression pistons, a header, CAI, less restrictive exhaust, some cams, headwork, and an ECU. I don't know if its ever been done. But I'm pretty sure it can be.

Sure, should be a piece of cake. In fact, Top End Performance (www.racetep.com) has in their 240sx/altima pricelist an NA engine rebuild that's supposed to give 210 hp. With 10.5:1 compression pistons, a reground cam, some headwork. I'm not sure if that is with a stock intake/exhaust/header system though.

I think the cars that Nissan shows in the Nissan Motorsports catalog also have 200HP. But those might be running carbs.

['97 S14 SE Turbo]

It's more like 300+hp carb... SOHC... Very unstreetable...

Any good high compression work and head work can get the KA24DE to put out 200hp. But the time you are done, you are already well past the cost of a bolt-on turbo system and less streetable.

Bang for the buck is for turbocharging. Nitrous does not count since you have to refill it indefinetly to have max power...

Bang for the buck is NOS...hands down....can't even consider a turbo car that much bang for the buck. Haven't exactly been to many KA turbo's last more than 20K miles so far...especially high boost one. Ty you said yourself, why run low boost, well that might be the way to keep on up for 100K miles, however a 200HP NA motor with some bolt ons could easily surpass the 225HP mark...and remain reliable.....and that to me is the biggest bang for you buck...RELIABILITY http://forums.freshalloy.com/forum/images/icons/smile.gif

Yeah, NOS is cheap thrills... not that I'm dogging on NOS or anything cuz I squeeze on my SE-R. But I have friends that have already spent almost as much money on NOS that they could've spent on a turbo setup, but then again it wasn't the OTC NOS setups you see them selling in the race shops. Plus I like the idea of being able to use the turbo all the time, that and you don't have to refill a turbo unlike the blue bottle. =)

Can I ask you a questionwhere you can get the Nissan Motorsport Catalog?

The Z concept car (the ugly one presented last year) had a 200hp NA KA24DE (prepped by Nissan themselves)

You may ask, but I may not tell you....just kidding.

Go to the contact page of MalvernRacing.com (www.malvernracing.com/contact.html)
Fill out their form, then click the bubble towards the bottom of it to request a Nissan Catalog.

I'm quite sure they only ship to U.S. destinations, but you FA members who are elsewhere can always try asking.

They're kind enough to send these catalogs out for free, so be good enough to check out their products while you're there.

['97 S14 SE Turbo]

funny, given my current situation, my '97 S14 SE Turbo won't even hit 50,000 miles until 2002!!! It only has 35,000-ish miles on it. Yes, that's on a daily driven '97 S14 SE. Yes, I do drive it everywhere, even WOT on racetracks hours on hours. I just don't have to commute very far...

As for reliability, famous Simon and his 400+ SOHC S13 is still running... with his high boost.... (remember him?)

As for mine? Well, I consider bang for the buck as the GRIN factor. More grin to my face for the money, the better. Remember my break down on why I prefer to roadrace vs running boring autocrosses or drag racing? $0.10 per minute or $10 per minute...

I knew the HP was somewhere up there http://forums.freshalloy.com/forum/images/icons/grin.gif.

Another way to get the catalog is through Nissan. They charge $5 for it. Did they ever release the 200o catalog? They usual send me an order form ever year. This year I never got one.

I not too thrill about using NOS either. Only practical use for it is drag racing. I don't like the refill factor also. But for bang for the buck, NOS is the champ. Well, at least until the refill prices adds up.

Ah....simons car had a problem about 8 months ago....can't recall what it was...I haven't heard from him in a while, but he was one of only a few getting longevity and performance....to me...I would want longevity...course my car is my toy thus its not that big of a factor with me.... http://forums.freshalloy.com/forum/images/icons/smile.gif

Rich dropped a rebuilt ka24de engine into his S14. He estimates it to be at 240 HP N/A!!! He's gonna get to a dyno within the next few weeks from what he tells me.

What is the compression ratio of the 92-94 KA24DE, and the 95-98 KA24DE in all of the 240SX? Also, what was the compression ratio of the KA24DE engine Nissan put into that prototype Z car?

All KA24DE's are 9.5:1 . Don't know about the prototype Z engine.

They might have designed new intake runners and maybe new head design, I am not sure but usually that would do the trick coming out of the factory.

I have heard of 200hp KA's at the fly, not to the wheels. He ported and polished the manifold and the head along with a head work and all the bolt on mods and the 10.5:1 compression pistons and Altima cams. JWT ECU is used and I think he has to use 100 octane gas everytime. Don't know if he is on any lists, but he is in LA and I met him at a local supermarket when he parked next to me. I think that sounds possible right? Especially when a JWT 200SX SE-R can do about 200hp the 240 should be capable of even more.
