I have a 90 gxl with s4 TII motor and transmission swap the car has turbo rear end. medium, large Street port and polish. it has a Turbonetics 62-1 ball bearing turbo @15psi front mount trust intercooler 3in downpipe and exhaust with Microtech LT-10C with x4 ignition box and bosch coils. to 1600CC secondary fuel injectors with a Walbro fuel pump.aeromotive fuel pressure regulator and lots of other little stuff

 

Put it on the dyno and find out, I want to guess 375whp. Have you taken it down the 1/8 or 1/4 mile track? What kind of traps are you seeing?

 

your trap in your sig and hp numbers makes me want to go back to the dyno i got 11.42@121.9mph , I havent redynoed my car since i rebuilt it and got megasquirt , i want to beat bnr's record for stock hybrid turbos i think its like 402whp

 

go Put it a dyno jet with crappy corrections=P HOw do we know BNR didnt?

 

on a stage 4.5 hybrid i'm sure it could be higher but i pussied out in trying to push it on a problematic customer's car which made 340@9psi where before it made 369@12psi before spitting an iron, rotor and housing on the high compression engine, i didn't get a run on it at 15-16psi before it **** the bed on the dyno floor.

pump gas sucks for some things.


i have never been thoroughly impressed with turbonetics turbos, i would guess 360whp. a waste for such expensive junk.

 

Thanks for the feed back

 

Problematic customers car or a customers problematic car, big difference there ******..!! Lol

 

the car :P

 

Lol

 

how much power is a good conservative amount to run on a s4 without having to have big worries about breaking irons?

my long term goal is 275-325whp on a bnr stage one

right now I'm on a stock s5 turbo

Rotary > Pistons

 

300whp is a fairly conservative figure for the weaker S4 irons.

 

yeah, this car is a street car so reliability/longevity is what I'm after while still having a.moderate amount of performance.
