Stock boost with bolt's on

[Touge180]

well isearched and couldn't find the answer i wanted but here goes my motors going in this week and i want to know what the bosst will be at it will have a intake, fmic, exhaust, possible downpipe, fuel pump,fuel filter,and i think tahts it i was told around 10psi but that seems kinda high to me

[180fan]

what engine and turbo we talkin about? this going in the 1990 240sx that's showing up in your profile?

[Touge180]

sorry about that sr redtop t25

Stock boost is 7-8. You should be fine up to 12psi, after that you need injectors/turbo and ecu reflash. Couple people have run 15 IIRC but retune is needed to benefit. Try going to the SR forum to get your answers

12psi on a smic, is bad news. another thing you'll be maxing out are injectors. running 10psi is ok, past that you're asking for trouble.

I have S-14, will put a S-14 Blacktop soon,was wondering how much boost i can have with:Fmic (Gtr) 3''downpipe,turbo outlet,3''Catback Walbro pump Blitz B.o.v K & N filter (dont know if the bov and filter worth writing but anyway )

Can I boost to 13-15 psi with no probleme(I know I can probably go to 13psi with no probleme but what about 14-15 psi)

I was wondering if my Intercooler (Gtr) is gonna fit without have to cut my bumper???

I think what he is asking is what the current mods on the car will yield. the answer is pretty close to stock unless you change the WG signal.

[180fan]

don't run past 12psi, you'll be maxing out the injectors and the turbo will be past it's efficiency range. go more and you'll wish you didn't. Injectors will be your limiting factor by far. Don't push your luck or like I said before, you'll wish you didn't.

gtr fmic, yes.

[S-14]

wg signal ???and i wont be able to go higher than 12psi even with t28-370cc

I have a sr from hey s-14

How much power will it make with my setup at 7psi and at 12psi

Also people with Gtr intercooler on the S-14,will post size later
