Cams with DBB T3T4 50 trim turbo on s13 SR

[Slideways^Jordan]

OK im looking to get new cams for my set up on my SR right now i have Brian Crower 272/272 and i don't like it too much its fun but i want a different cam setup. I'm thinking about getting HKS cams and reshimming them for my Tomei solid lifters. Right now my turbo is a T3T4 DBB 50trim with a .63AR turbine and it starts to hit full boost at 5000 and i dont like it and I just ordered a .48AR turbine housing for my turbo to replace the .63AR. I have a greddy intake manifold peak boost exhaust manifold and FMIC but im changing it to mid mount soon and im thinking about putting the stock intake manifold back on for spooling reasons.

This is what ive been thinking about so far HKS step (1) 256 Intake and HKS step (2) 264 or possibly a HKS step (2) 272 for the exhuast

256IN/264EX wouldnt this be a really good stagred cam setup or 256IN/272EX << and is this even possible or what would it be like in the powerband. I have an idea but im not very sure, would the 256IN/272EX come on really quick and go hard all the way to redline, but im not sure thats why im asking zilvia!

Can you guys help me decied what I should do!

Thanks

264/264 if u get hks. It'll be nice with that turbo.

.48 IS SOOOO TINY :P

[Slideways^Jordan]

Nice Thanks smelly240 so 264/264 would be really good? Any one else have any other opinions i like the 264 step 2 their really nice on SR my friend had some on his with 2871r and it was really fast!

[smelly240]

Step 2 i think req springs - good idea either way.

Thanks man I have all Brian Crower Springs and Titanium retainers in my SR head because i have the BC272 cams in their right now.

Thanks

tomei 260/270 will be a nice combo

How would the torque be cause i really want the Tomei cams to run with my solid lifters you know!

[Slideways^Jordan]

As of right know im going with the hks 256/264.

Does anyone know if its possible to use a S14 SR intake cam on A S13 SR!?

I am running a very similar setup on mine. I have the journal bearing 50 trim w/ .63 housing, and HKS 264 step 1 in/ex. I am running and ethalpy tune, stock intake manifold and peakboost exhuast man. too. My car felt laggy as shit too, but I thought it was due to my downpipe. The guy that did my exhaust did the first 6 ft. in 2.5 in piping even though I told him to do 3in. My car hit full boost around 4800 to 5000 tho. I am hoping when i get mine back together w/ 3in downpipe it will spool alot better. I have 2 friends that have eagle talon tsi awd's and were running the exact same turbo and I had the chance to drive one and I swear it hit full boost no later than 4000, prolly even 3900. Does anybody have any input on why ours are so damn laggy

I believe it is but dont quote me on that (at least HKS -)

The 264 Step 2 is what i use on my car.

Expect a wide mid-range (5k-7K the strongest) with a hump like torque curve at about 6k.

Great for 50 Trim car.

same as this car - only we used .63 housing with stock IM - car spooled 13 psi with P trim T4 turbine wheel by 3800 RPMS

hmm interesting Nice video by the way, well i think i might use the 256 intake and 264ex step 1's with the 10.5mm lift cause I want it to spool between 3000-4000 and have a good tourqey feel to it.

[Slideways^Jordan]

Last night I ordered HKS step 1 264 intake and HKS Step 1 264 Exhaust these cams should be really good for the new .48 AR i bought.

Yea, with the stock 7.5k rev limit I think 264/264 work best.

I have 264 Step1's and really like 'em, although I was a slacker and didn't upgrade the valve springs, which I'd like to do someday as I feel there is still power out to at least 7800-8000 RPM with my GT2876R. There's a bit more power to be had with the extra lift of the Step 2's, but not enough to worry about, especially if you're going with the 0.48 housing for more low end power.

I wouldn't worry about the small top end loss you might experience at all, and you'll probably gain quite a bit down low.

That's exactly what i was thinking Thanks man :). when my car was tuned on the AEM stand alone it put down 301HP and 226FTLBS of torque at 12 psi of boost on a dyno dynamics dyno. Now when i saw that i thought to myself theirs really a huge gap in the these numbers in the power band and torque and driveng the car didnt really feeel like their was any low end tourqe at all just all topend. Hopefully with the new .48AR turbine housing and HKS 264 step 1 cams and a new tune this will fix all of that and ill get the redline set to 8000 rpm maybe if its possibble with the hydrualic lifters, I hope so. And then ill up the boost to 22psi :)

[Def]

8k RPM is right on the edge with HLA IMO, but FWD SR guys do it often.

You should really run more boost than 12 psi. 1 bar is my low boost setting and it doesn't feel like anywhere near as fast as 18-19 psi.

[Slideways^Jordan]

yeah i want to to run more boost like18-22 psi!!! ;) ill have to ask the tuner what he thinks about the revlimit for my SR maybe like 7800-7900 you know!

Have me do a remote tune package - youll probably make more - hp

:coolugh:

he he -

I would set rev limit @ 7800

You should run 18-19 psi max with 91-93 octane.

20 psi and you will be into the turbos efficiency nicely

30 PSI on C16 if you want to make some real power.

that's how the aussies do it

those specs sound great but i doubt youll be able to tune my AEM EMS un less you came to me right if that was what you were saying.

**EDIT** what does remote tune package mean?

[Slideways^Jordan]

right now im building my engine with 87mm CP pistons and eagle rods and ACL race bearings. ill just stick with the .48ar turbine housing cause id like to try it out and I have the HKS 264 step 1 cams now sitting in my room.

**EDIT** what are the benefits if i get the 9:1 compression 87mm cp piston i heard it will help spool up? now which compression ratio is better for what im doing the 9:1 or stock spec 8.5:1?


Thanks

Jordan

[godsmack]

Go with the higher compression you'll enjoy it more. You'll get more power with higher compression and alittle quicker spool up.

Sweet thanks man does the higher compression pistons affect the torque any also?
