oy... but people are saying 34 and 39 are good with the tmic and if i have a fmic i should go bigger... what does everyone think
You COULD have a fmic with a 34/39 but will gain minimal hp and will lose a lot of driveability with the added lag. On my old car I had a vf34 and eventually went with a fmic..only gained 9whp and like 15tq, I completely regretted it.

This also come from a person that was putting down 380hp 400 tq on a 2006 WRX tr and a stock 5 speed and clutch.
I wanted to upgrade the turbo and make more power. So I did that and upgraded the car. I knew if I wanted more power I was going to bust the tranny. I have over 84k miles since Oct 2005 60k of that in the upper psi ranges. Yes I'm a beliver that the driver makes or brakes them more then poor design. But everything has its limits so I felt it was time to upgrade.
The 02-05 5 speed I dont think take that much.

You are also running a 2.0 which will lag on a big turbo as well.
With my aps system stock injector and fuel pump TD04 ->

See no lag... That was in a 110* day in phx

well i really ddint want to go with another top mount as i have been wanting a front mount all the time since i got my car... i just wanna know whats a good turbo to put on along with some injectors and fuel pumps...
Did you just want a fmic for the looks or something? It's all up to you and what you want. You can keep the FMIC and have some more lag or you could go with a big TMIC and have a car thats more fun to drive around town and such.

well i just got a deal on a fp18g so that will be going into my car when i have the injectors and fuel pumps to go with ti

Like Al said, your car is HATING you! Cobb AP Stage 2 map is for a turboback exhaust ONLY, you have everything wrong. You need a custom tune ASAP. I would not drive the car until its tuned for your mods.
Sorry, I'm not trying to be an A-hole, just being honest. Call a tuner close to you and see if they can email you a base map until you can get it custom tuned. Good Luck.
