hey this might be a stupid question for you guys to answer because i know the only way to prove power gains is from a dyno but...i know alot of you of running the same setup so what kind of power am i looking at with these bolt ons

S13 Redtop SR20DET
12psi
ARC BOV
FMIC
3'' Full exhaust from DP back
SSAC Turbo Manifold

on a t25...

If you want some serious power, you gotta spend the $$$$ and get a whole lot more parts on your list.

If you have a leak in your intercooler piping your car isn't going to run like it should obviously. Take your time and spend the money otherwise it's going to cost you double what it should have. I've learned the hardway many times.

like what...what are some good bolt on's that the SR will respond to well

i'll be doing 550cc injectors soon with a T28 BB S15...and a walbro 255...

my intercooler currently has a dime sized hole in it right now and the piping uses like 10 fuckin couplers...i really need to upgrade all of this first...and yes you are right , ive learned that also

you're boosting 12psi without a walbro?


thats quite dangerous....i wouldn't advise doing that.


if you're looking for power...

first off change that IC setup you have since you've got a hole in it.

you're going to have the S15 T28, 550's, and walbro 255...i would add these

-Greddy manifold
-turbo elbow(if you dont have one already)
-APEXi Power FC & Commander

benefitx
03-21-2007, 07:12 PM
whats so much better about the greddy manifold , as long as this SSAC doesnt crack im good right?

and why is it dangerous for 12psi without a walbro?

well i dont feel like starting another thread but...i have another problem..

sometimes if i drive my car hard...drift a little , my car will turn off when i come to a stop...i dont know but its happened twice now....and im pretty sure it was in neutral...

because you have a non recirced blow off valve. your dumping to atmosphere and you have no ems at all. i doubt you are even makin 240 hp or anywhere close to that. you need to tune with ems of some sort to run more psi. more psi doesn't make you faster, you can actually make yourself slower if you're running lean and really fuck shit up. your wholse set-up is half assed. recirc your shit since you have no ems or piggy back and drop the psi back down to 7. and build it the right way. or do you like melting pistons.

umm no way you are even close to 250 whp with your setup and 12 untuned psi. with a tune on your setup you would make about 215-220 whp. recirc your bov. it cost 20 bucks. you will make more power with your current setup unless you get full standalone or convert to map.

i just put my MAF back on the cold side....let it idle and it stuttered and died...turned it back on , rpms stutter when under 1000....i guess it takes some time for the ECU to recognize, idk

yeah blow through setups can be tricky they work for some and not for others. i have the same setup but i'm stock location maf but i recirced mine. your car won't smell like gas anymore. i have full 3" from the turbo back and running 13 psi but i have a tune with my afc.

You should think about just buying a whole new intercooler. That way you get all the proper pipes and couplers that are intended for your car. The piping set up looks rigged as hell. It definatly isn't helping anything.

IE. 2 different kits, and the stock junk mixed with the junk that your bov came with. I'm just saying instead of mixing and matching and worrying about leaks....

lol damn your pretty good...i know that the piping is fucked up...its like 6 different pipes and over 12 couplers...i really need to fix that shit....its just i need to do fuel pump first

not exhaust manifold, i mean greddy intake manifold.


running 12psi on stock fuel pump will kill it. its not safe to turn up the boost unless you have the fuel pump to support it.


like everyone else said, get some kind of tuning tool, boost safely with upgraded fuel, and make sure that forced air is cooled properly with a better FMIC setup.

what would be the best way to tune it? also easiest...SAFC2?

oh and the only reason i have a blow thru MAF is because of the atmospheric ARC bov

These what kind o power threads are so SUBJECTIVE...

Ive seen so many motors turbo ka to sr that have some stupid ghetto mis placed installation or bad base timing.

Usually a dyno (any freakin dyno) will give you a ball park of where you are.

just pay 50 bucks for a couple pulls.

SAFC2 is basic tuning.


a GReddy Emanage or APEXi Power FC and Commander is the best way to go.



you should seriously turn the boost down to 7 until you get that fuel pump.

ok well the idle is almost near pERFECT now...800 and steady...doesnt stutter...this is after i did the blow thru setup....i also turned the boost back down to 7...the powerband is alot smoother now...i guess its for the best until i get injectors and fuel pump

that is very debatable. they have been known not to hold their tune after time. i would just say standalone in general is a good way to go but not the best way. for a setup as basic as his i wuold recommend a daughterboard and chip with basic timing and fuel map. and then tune on top with afc. it'll be cheaper and easier right now. what you mentioned is 1200+bucks. and you haven't even gotten it tuned yet. what i listed you can still safely make over 400 whp relibably with at a cheaper price. but you gave him very sound advice even though it's a little pricey. but you gotta pay to play when doin it the right way :-)

okay. good you turned the boost down, making sure you dont blow something out before you get the proper parts.

yes the Power FC costs much more. but if he is going to up the boost and be running it safely and obviously having more power later on down the road.

they why would you even cheap out and not do it the right way the first time??

Just save up for the Power FC and save yourself some time and money. It'll be worth it in the long run. Much more tuning capability.

the nipple doesn't get used, cap it off. the top nipple goes to your bov.

it's debatable if you ran lean or not. that's the issue. you'd have to do a comp and leakdown test. i doubt you did any damage though. but should you run lean for some reason and fuel pressure wasn't sufficient then you would really fuck shit up

i'm saying that calling the power fc the "right way" is debatable. not EMS in general. but daughterboard has been proven to be just as reliable and not lose it's tune like some power fc units can. so i wouldn't call them reliable. and they don't do nearly half the shit they could do. they are overpriced for their features. i even checked around with multiple shops and 1 personal tuner and they all said the same thing about the power fc. if i'm spending 1300+ bucks for ems it better be worth it.

running the car at 12pis wont necessarilly hurt it unless it ran lean like wvustud2003 said.

if anything that fuel pump is probably just about dead.

ive never heard of the power fc having any kind of problems like that. i have friends who are running them and have no problems. either the Power FC or the AEM EMS......they're both a great way to go. I dont have much experience with the daughterboard but im sure a rom tune and SAFC2 will be quite sufficient.

yeah. once that fuel pump is in you can turn up the boost. when you get bigger injectors you're gunna need that tuning tool. have fun!
