with those mods, you're looking at about 320hp...if you want more get a gt2871 and a better ems

Dousan_PG · 05-09-2008, 11:23 PM

get some cams!!!bigger injectors

a standalone/tune

mikey0129 · 05-09-2008, 11:26 PM

is that 320 to the wheels?hp

JeremyR · 05-09-2008, 11:31 PM

that 320 is the max most people have seemed to make on a similar setup, depending on alot of things that could be either to the crank or the wheels. condition of your motor, parts, blah blah blah, all that has an effect on it.

like dousan said, cams, a standalone ems, (haltech, PFC), some 555 or 740 injectors, and a biggggerrrr turbo will get you 350-400whp easy.

you wont get over 300 with out cams, im running a s15 t28 and only managed about 280ish on 18 psi with BM's. Ill have my built head on next week and get my ecu, ill make sure you to post videos for you. To be honest 550's for 300 hp is fine, if your going bigger then obviously 740s are the solution

mikey0129 · 05-10-2008, 08:38 AM

who the setup that i mentioned above be reliable ?

Psycho 240 Freak · 05-10-2008, 09:05 AM

That set up is very common on SR's. I dd my car at 1 bar and I don't have any problems. As long as you have a good tune and keep your boost pressure reasonable, there shouldn't be any issues.

This is only true for you...
I have an s13 redtop sr20 and an s15gt28r, 555cc Deatschwerks(sp?) z32mafs stock cams. With the AFC tune, I made 305whp/302tq 16-16.5
I haven't dyno'd with the romtune as of yet! This was a mustang dyno!
I dyno'd 340 or something ridiculous on a dynojet, that's why i haven't been to a dyno in a year. I do hear the cam story a lot though, why do yo think the cams are holding you back? with cams I think I might see 320whp.
Engine condition and tuning...!
