View Full Version : Building a Strong SR Head

I am building my SR head, I am going to run 264 step 2 intake cam and 272 step 2 exhaust cam both HKS. I heard the HKS Springs aren't all that great, but the Greddy and Crower options are pretty good. Any thoughts, I want to get it all done while I'm in there, can anyone give me some suggestions for nice reliable setups.

greddy have a bad rep, and ive seen a couple break

Crower, Ferrea are the best imo

I have also used Peak Performance (Racing ones) with success on a couple heads with 264 step 2s.

Peak performance stage 2

solid lifters

9000 rpm easily

ORRRRRRRRRRR

supertech springs and retainers from mazworx

solid lifters

10k+ rpm easily

its your choice!!

10k+ rpm easily?!?! Would you need to build the block and use higher comp pistons?

I wouldn't trust stock rods and pistons to 10k RPM for extended periods of time personally. The loading on the components goes up with the SQUARE of the RPM. So 7500 to 9k is ~50% more stress, and 7.5k to 10k is ~78% more stress.

Just seems like pushing the limits too much with stock components that weigh a bit. Aftermarket pistons/rods are not only lighter, but almost always stronger and more ductile, so they'll withstand the stresses much more readily.

I have wiseco pistons and eagle rods, BTW.

I would not rev stock lifter heads above 8000rpm, which should be good for what you have selected in cam, I ran strait 264 step 2s last year and I've switched to strait 272 step 2s this year. I run the HKS springs, I'm not concerned that someone has tested these springs to say they are not very good, I know that HKS says to run them in there step 2 series camshaft and it has worked for me well. Take it for what it is worth I guess.

Had the HKS Springs swapped them out for Comp, I am running HKS 272 step 2 cams.

Does anyone have experience with the new crower cams?

What about a set of Crower replacement valves instead of just doing a 5-angle on the stockers?

i have Comp springs as well. Im also using Crower retainers and retainers, with JWT bronze guides.

I almost got the brian crower components, but didnt want to take a risk, they hadnt been tested yet.

Well talked to the guys at Enjuku and they are telling me to go Tomei for the solid lifter head build. My goal for now is 450+ but I know myself, and 450 won't be enough for long, so I want to build something that can handle more. Can anyone think of a better setup, keep in mind I will be driving this on the street most of the time.

Pro Cam Solid Type 260 Intake 12.0 lift
Pro Cam Solid Type 270 Exhaust 12.5 Lift
Valve springs Type A 12.5 Lift
Solid Pivot
Valve Guides
Rocker Arm Stoppers

Just do strait 270-degree cams, is there some reason your using a staggered setup? You can really man up and throw in some 280-degree shafts.

I wish I would have gone 272/272 instead of the 264/272 that i have now. My tq drops off like a mofo past 7000-rpms. Its seriously like hitting a brick wall. Im pretty sure the 264in is maxed out at the power im out. I think a 272 would hold better. If you seriously think 450 wont be enough then go with 270's or like James says man up and get 280's. Hell ill sell you my 264 so I can buy a 272...

I agree I should run 270 all around if I go Tomei. See your opinions are helping me decide how the build should go, Thanks.

go as big cams as possible so you have as little lowend tq and power as possible!

Might as well buy a honda...

Back to topic - GReddy springs here with JWT c1's (close to the HKS 264 step2's) - no issues YET.

I already have a Honda Accord with an H22A I don't need another one. I am going down to the Enjuku shop this weekend, I'll let everyone know what I end up with.

the tomei kit is not something i would reccomend. I would do the HKS kit before doing the tomei kit. You can install the HKS kit without having to re shim your head.

You have to re shim the head (with a $700 tool from Nissan, unless you buy one of mine for $600) when you do the tomei kit. That's alot more money. that sucks.

I designed and built a lifter kit that doesn't require re shimming like the tomei kit OR custom shims like the hks kit , but I don't sell them to private parties, only dedicated motorsports operations. (liability and stupidity)

Or else you can just get a job as a tech at a nissan dealership. Then raid the tool room friday and take a bunch of **** home for the weekend.

Oh wait thats what i did yestday

Why would you have to reshim the head?

And are those tools really that expensive? I picked one up here in the classifieds for $150, haha.

becuase you can not change the height of the tomei lash killer. it is set in stone height. the only way you can change the lash to the rocker arm / cam lobe is by changing the height of the shims on the valves.

not only that, but iwth the tomei kit you have to buy different size guide shims (the ones with teeth that go on the left valve) to maintain the .001" height differential between left and right valves per rocker arm.

and anything coming from japan takes forever to get.

or you get the HKS kit, and you can use what you have to make it work, save for some shims that you get from mazworx custom made.

or there's this other guys kit that doesn't need any of that stuff either...

I didn't know its height was set in stone. The part that confused me is that reshimming the head would require different sized guides, which I didn't think were available; that's why I asked.

It's a shame that other guy's kit isn't available yet so unfortunately we're stuck with limited options.

Yeah , the last that I heard that other guy was having all these ricers and people that don't know WTF they are doing try to buy the kits, and he pretty much has decided to sell them only to people who are truly dedicated and familiar with the SR's. but i heard you could email him..

dam SR reving to 10k i bet that must be crazy sick sounding. I herd a few people saying you could do this but i though they were just talking BS being this was like 2 1/2 years ago.

well, i haven't gone that high. the high rev head masters are mazworx. I've gone over 9k a few times, and i mechanically over-revved to 9500. oops. nothing broken though. i routinley hit 9.

I am breaking rockers? 264 brian crowers, comp springs, ras. I think it may have something to do with the ignition cut (aem). I need to fix this before next season starts. I would like to be able to turn 8200 but right know 7700 is hit or miss if it will make it though a weekend? I am finishing a new engine for next season and havnt bought the valvetrain yet. For the money what is the best set up for the least cash?

MATT_BACK_VASS

JYou are not breaking rockers because of the ignition cut. You are breaking rockers because of the hydraulic lifters.

too many people on the web are sayign rocker arms fail when you have a spark cut ignition at high rpm. that's just bs. lifters collapse at high rpm, period. you need to do solids so you can two step at 8000

email me.

Has anyone run Brian Crower Cams yet? They are all over the place and cheap by comparison to HKS.

silver91240sx (http://forums2.freshalloy.com/member.php?u=23919) who posted just before you is. His car has been running really well with the BC cams. I think he uncorked about 30 to 40 hp by going to those cams.

I think I decided to run BC Cams, since I was originally planning on running HKS 264/2 and 272/2 does anyone have specs on the HKS cams, I want to know how much lift the HKS cams have so I can compare with the BCs. BC 264 kit has 12.06mm of lift the 272 set has 12.55 mm of lift I talked to Brian and he said go with the 264 since the car is going to be a street car for the most part. Anyone have the HKS specs?

i have those cams in my car - so far so good... i have get some better valvesprings before i crank it over 7k - but like i said - so far so good. they have a buttload of lift compared to hks step 1s
