How much power will this weak setup put out?

[oilsquirt]

Just out of curiosity, wondering how much power this setup will give?

sr20det on an s13
t25 stock turbo pushing 12-15 lbs, on occasion
3' down pipe megan 3' all the way to 4.5 tip
apex turbo manifold
hks intake
blitz inner cooler with piping
greddy rocker arms
750cc injectors, 300zx fuel pump
hks b.o.v, blitz turbo timer and boost conroller
welded diff
stage 3 clutch and l.w flywheel

Not much things done to my ride, but just wondering on that setup how much horses will it give? boosting that amount of psi? thanks!!!!! :D

[Corbic]

Why not dyno/track it and find out.


If I had to guess 1100whp. 2jwhat?!

what are u using to tune for injectors?

[projectslider]

if u have a t25 turbo........ would u need apexi headers?? wtf?
or did u mean apex head gasket?

[oilsquirt]

yes using a tune, after its done, and apex turbo manifold sorry my mistake.
What horses am i expected before/ after tune?

[Treefish]

Probably around 200, or just under. Turbo won't last long though. 10psi is safe, reliable, and won't over cook the little turbo.

[oilsquirt]

Doesnt a stock engine put 205 horses?... Plus the mods i have?

[jontron5000]

205hp to the crank, wheel horsepower is obviously less.

I wouldn't run more than 12psi on that t25 if you want it to last.

I'm running a stock redtop with a fmic, 3" straight pipe, and topspeed intake manifold. made 206 at the wheels on 7psi and no tune. Ran 12psi for a year on stock injectors and a walbro 255, and was still pulling 12.0 a/f on the uego at wot.

Honestly I wouldn't waste your money on the 750cc's for that setup as there is no need for them.

Recently installed JWT S4 cams, waiting to get 550cc injectors and z32 maf, we'll see how far I can push this t25.

I'm running a stock redtop with a fmic, 3" straight pipe, and topspeed intake manifold. made 207 at the wheels on 7psi and no tune. Ran 12psi for a year on stock injectors and a walbro 255, and was still pulling 12.0 a/f on the uego at wot.

I agree. Don't bother with injectors espcially that big. It will be a waste of tuning as well. Sounds like you should keep everything stock settings to save yourself a ton of headaches. You can get a manual boost controller later or an adjustable wastegate to add a few pounds of boost if thats what you are looking for.

[TheRealSy90]

Exactly, Like I said I was running 12psi on stock injectors without a tune with no problem.

[R33E8]

Why do people act like getting bigger injectors is such a bad thing? The only reason not to get injecters over 1000cc is because they have trouble idling smooth.. tuning for larger injectors will take the same amount of time and they usually cost about the same.. I'm running 1000 cc injectors on my daily driven ka..

[oilsquirt]

The reason im running 750cc's is because it came with car.. so im not going to buy 440s to replace them ya know? Im saying this is the setup i currently have and im wondering what hp ill be runing to the crank & wheels. Im riddding this car before winter and is currently my daily till then ;P

[Tom25666]

if 1psi is good for roughly 10hp then your setup should be around 250hp at the crank

[[email protected]]

stock SR is about 180 to the wheels. with this setup, im sure you can get about 215-220whp(tuned)

[oilsquirt]

Damn, and how much to the crank?
Felt like 300hp when i gunned my baby xD

[Psycho 240 Freak]

First time I drove a 240 with a SR I felt like it was the fastest thing ever too. Take it to the 1/4 mile track and see what your trap speed is. What MAF are you currently using?

[oilsquirt]

mass air flow sensor? stock sr20

[R33E8]

Who told you that? I'm pretty sure 20psi on my 35r isn't the same as 20psi on a t28... It's the amount of cfm that makes the difference..

[fliprayzin240sx]

Basically, you'd be lucky to see 240-250 whp with a stock T25.

[Sleepiedaze]

its all in the tune. get yourself a AEM EMS or equal ecu to tune it AND a reputable tuner. dont do any of the freeway pull tune bull shit either. thats just dangerous. pay the money go to a real tuner with a dyno. do your pulls take it out to the track drive it around go back to the tuner for some fine touches. dont be to focused on power. focus more on when the power comes not how much power comes.

whats the point of having 400+ hp if all the power starts to spool at 6000 rpm and you red line at 7500. focus more on throttle response when the power comes up and how it holds thru out the RPM range. ive seen many mildly tuned 225 hp cars easily smoke higher horsepower cars on the track becuase of the tune and when the power comes on.

[R33E8]

Any full stand alone is a waste of money for most people making under 500whp.. save your money and get a nistune or calumsult..

[whereda40at]

im going with 235whp

[Weedm]

^ thats if his little turbo doesnt blow up at 15 lbs..

Be happy with 11-12 lbs, and probably 220 whp.

[seanforney]

My guess is just over 1027HP, just my .02 since everyone else is throwing out crazy number. Prolly 225-235WHP.

[SR20Driftking4lyf]

I put down 240 something (cant remember exact numbers) with red top SR, 264 cams, titanium springs, valves retainers, rocker arm stoppers, port and polish apex HG, apex n1 duals, intake, blitz front mount, Z32 MAF, 370cc injectors, nismo FPR, T25, 15 pounds using apex AVC-R and NEO afc. I also made around 215 give or take on 10 pounds. This was on a dyno jet, ill find the sheet and post it...

[PerilousActs]

It's Apexi, everyone. Apexi.

As already stated, I'd stick with stock injectors for that setup. If you go with a t28 then you will want to upgrade though.

[Prok0]

Dont buy the manifold, RAS, turbo timer, or boost controller, get your stock flywheel resurfaced, use the money you saved to buy like an S14 turbo or something equivalent, and an adjustable wastegate, and a tune.

It will make more power, not have to worry about cracking/warping manifolds, and you wont really lose any response.

[oilsquirt]

These are parts currently that i own.
They are on the engine.
The engine is getting swapped in, just wondering what it will put out..
Does the t28 swap right into the t25 turbo's place? Like no work needed really?, or?

[Tom25666]

Who told you that? I'm pretty sure 20psi on my 35r isn't the same as 20psi on a t28... It's the amount of cfm that makes the difference..

well obviously. this is just a rough guideline

sorry but 15 pounds wont happen. if you want a factory turbo that can hold 15 pounds get a S15 T28 BB. T25 is only good for 12-13 max. 750's why? your SR come with them?

[chituntang]

I run something similar at 11psi and have 210whp

Stock engine, turbo, injectors, maf
3in turbo back
stock exhaust manifold
FMIC
stage 1 clutch w/ stock flywhell
Aftermarket intake

[TheRealSy90]

^ Which is exactly what i'm running on mine. I made 206 on 7psi as shown in the dyno graph I posted.

I guess the 750's will work if it came with them, your going to need something to tune your motor on at that point.

[anfitch2k5]

i had a stock t25, stock inj. stock maf, no tune, just exhaust, FMIC at 10psi and made 204.
my .02

[jklein122]

I'm going to echo what everyone else is saying -- your turbo is tiny man, at least upgrade to a T28 minimum.

[nujabe]

weird you guys say you cant do 15 psi on a t25 but i ve been doing it for over a year now... but i would not recommend it get the t28 =D

Cool story, thanks for bumping this month old thread to add your already stated opinion.

[sr20s13abel]

ok here is what i got ...
mostly stock type x motor t25 at 14psi made 230whp. i have 264 hks cams. 550cc z32 maf greddy intake manifold springs n rocker arm stoppers mustang dynoed. power fc ... avc-r for boost. i ran at irwindale dragstrip.. 1/8 of a mile i ran best time 8.0 once.. and consisten 8.2

then i upgraded to a gt2540 hks turbine and headers. same setup made 325 whp @ 20 psi with race fuel because motor is all stock headgasket n bottom end../ i ran 7.7 spinning tires @ 93 mph. so i got me some drag radials n went to 7.5 all day very consistent. am always @ irwindale.. its a black rhd silvia..

i can easily get more power on the gt2540 turbo but its an orignal motorex silvia n very clean so i dont wanna fuck it up too much.. i work at sr20store in gardena so if u wanna ask me something and i know i can answer or i can ask marco that old man knows his shit..
