i have a 98 gst with the following mods:
fmic
3" turbo back exhaust
greddy bov
injen intake
tubular exhasut manifold
no mbc yet, the turbo is stock so what yall think i am at right now. hp wise.

no one can tell you for sure. get it dynoed, then youll know for sure. if i had to say or be kicked in the nuts though, i would guestimate you're at 220hp, or approx 195hp at the wheels. take that with a grain of salt.

Yeah just get it dyno'd. And you are losing power with that FMIC. The lil t-2hairdryer cant pressurize all that piping, especially if you have a long route FMIC. Time for an upgrade!

take out your boost limiter. if you don't know what i'm talking about PM me. and with those mods you said you'll be running at about 15psi. i had some simular ones and was up at about 17psi steady, but you have a FMIC which drops a few psi, but also gains HP too. after that i'd say you'd be doing pretty well for a stock turbo gst.

Sorta right. That FMIC is going to make you lose presure in your IC and pipes, but its not going to GIVE you HP. Instead it will support much more for the bigger turbo to come in the future :D

I'd say about 175-185 at the wheels.

+1 on this and getting it dyno'd. or if you have a DSMLink log the HP and torque perameters and that will be accurate within 5hp/ftlbs or so
