greddy, tomei, hks, and some other random company. I was thinkin either greddy or tomei

[DrifterProdigy85]

RAS are all the same. I use Greddy since there pretty cheap.

[idahotuner]

i didnt installany in my haed. didnt see the pint as i wont be reving high enough to worry about it.

[gordonliu]

trying to build 300whp s13sr. assuming all necessary upgrades (exhaust, intake, fuel management, tuned ecu, fuel stuff, other nick nacks) and a t28, what cams?80/20 street/track no drifting, no dragging.

I was thinking 256/264. do you think ~10.5 mm lift will do it?

probably get all new valvetrain anyway, should I get solid lifters? I dont ever plan on revving the crap out of it.

[idahotuner]

get 256 cams and new springs and call it a day

[RCCC_DRiFteR]

+ 1

[s13_silvia_redtop]

as long as you not reving really high you dont need solid lifters. if you did get solid lifters you would have to get cams made for solid lifters. also you would occasionally have to reshim them. but for your the setup you have, i would just get a valve job with new valve stem seals, and while the shop is doing the valve job have them put your springs and retainers on, they should do it for free since everything is taken apart anyway.

this is waht i had done. minus the new retainers. and i am not sure what you mean by valve job, but for my motor is wasnt nessicary.

and no the shop wont do it for free.all my head work came out to about 160 bucks.

[s13_silvia_redtop]

i took my motor to the shop and they did a 3 angle valve job, cleaned all the valves and faced the head, also vated the head and when they did the valve job since all the parts were out they went ahead and put the new spring and retainers in for free, came out to be like 150. i have taken all my parts to them they seem to be a reptubale place for cheap.

and what do you plan on doing as far as tuning? are you going standalone or are you going to get a daughter board?

[idahotuner]

vated the head? never head of that.

i am going wit ha reflash from either enthalpy or JWT

[s13_silvia_redtop]

yea vating is when they put your block or head in a chemical bath. im not sure that its the correct spelling.

and about your tuning are you just going to leave it at that or are you going to get a piggy back system to tune it after the reflash? or a wideband? and what horsepower are you going to be around?

[idahotuner]

a reflash is all i will do. they are usually spot on. i am aiming for 400 whp. on high boost.

[RCCC_DRiFteR]

what bout Apexi power fc??

[idahotuner]

i thought about that but i have no idea how to tune it. and it would cost alot more to buy that and have soem oen tune it. reflash is the best bang for the buck which is how my build it made

[RCCC_DRiFteR]

I'm still really stuck between building my SR or building a KA-T. My friend's KA-T is crazy fast!!

[idahotuner]

if you have an sr build it i say

[DBo]

im thinkin about runnin BC 256/264 o 264/264 cams in my sr wit a t28. im tryin to shoot for 275-300hp on 15ish psi. im unsure which would give the best results. also thinking about upgradin my valvetrain too. im thinking about using BC valve springs and retainers to go with the cams.

would it be better to run that staggered setup or just run straight 264s?

[idahotuner]

i would run the same cams. 256 cams should work fin. but with that said stock cams could work fine to. is it an s14 sr20det or and s13 sr20

You wont hit 300whp on 15psi with the T28. Just doesnt flow enough air. But you can do 300whp @ 18-20psi with just a ECU tune, injectors, and maf. 256 cams would match best with the T28. i highly suggest upgraded valve springs as well. i already blew an SR from valve float using the BC 264's on stock springs.

[S14toRPS13]

What would you guys recommend for me? I'm running a HKS GT2530. It's reaching full boost of 10 psi by 3500 rpm right now. I'm planning to run 14 psi though. So I'm guessing I'll be hitting full boost of 14 psi by about 3800 rpm....? 256 or 264? Also would I need to re-flash my ecu for the cams?

i would say leave the stock cams in there. maybe 256 duration.

yes you would needa reflash for new cams.

[arauz]

My question is, how would VCT make HKS 264/272 cams behave? Would my powerband change sequentially with VCT or should I get Cam gears as well and get rid of VCT?

My last question is, for quick response would straight 264 cams work well with a gt30xx turbo. any suggestions would be appreciated.

[idahotuner]

for a gt30XX turbo depending o nthe application 264 cams could work or 264/272 for more high end 272/272.....

as fars as VCT i am unsure i havnt messed around with it

[Jjona5]

Tomei 256 ftw. I run a GT30r with a t25 style manifold or a disco potato depending on if im going to the drag or around town.

[sa3reghatch]

I just got finished with my build on my SR. got a dyno baseline at 13 PSI(didnt have the MBC turned to 20psi which is what I want). Anyways, my setup is built motor, HKS 264 step 1's, Full racetwin scroll manifold and twin scroll gt3071R,enthalpy rom tune,830cc injectors, greddy intake manifold, Z32 maf,etc. This is my dyno at 13lbs. If you cant read it cuz its too small it reads 300HP 278lb tq. For some reason it seems a little lower than I expected, i compared it to the dynograh they have on full race's website,and the full race graph seems to have it spool faster than what mine is spooling at. i know their are different parameters and setups, but I would think they should be more similar than they actually are. I'm assumming I need to run different cams. need to check all my vband fittings and make sure they are tight and I dont have a exhaust leak.



gonna fine tune it with a SAFC to lean it out and raise boost to 20lbs. I'm looking for 400+HP and 330+tq. Think that is reasonable?

[idahotuner]

easily. you should be ale t odo way more then that. specially wit hthe twin scroll set up because yo uhit the power sooner. cams could be the reason. mine try staggered or 272s

[Rapeacivic]

I have read all 5 pages, some really good info on here and it has helped me out quite a bit

My question is, I am going to be running BC 264/264 cams with BC Spring and retainers along with a 2871R .064 AR turbo, should i have any problems running this setup on stock pistons and rods and will the motor still be reliable as a DD? I am also elimating the VVT(S14 blacktop), will I notice much difference in power without the VVT or should I look into keeping VVT and getting another VVT solenoid?(my VVT solenoid is bad.) I am hoping for around 350whp.

Thanks in advance for the help from Spain,-Terry

[idahotuner]

that is pretty close to my set up^ cept i have a redtop sr20det.

350 should be dueable depending who does the tune.

[cartoonlips7]

this is to everbody but i'm going to stay with the stock t25 for now doing alot of bodywork and rebuilding my sr so money is tight in a few places but with the stock t25 would it really matter to do cams? know i want jwt components mainly s3 cams but a need for now?

[sideslider240]

cams not necesary on t25 at most a 256/256 256/264
