trial header has not proven to be any better then DC sports header. which is sad cause you could buy 3 dc headers for the price of 1 trial header.
I agree that there is no cheap way.
You could stroke the motor and go ITB's, header, power fc, exhaust and get good N/A hp and tq. will take a lil work to make it streetable but hey it will get the job done lolIntake
and power fc I put down 183 whp and 135 wtq Not bad for a gts
GT is NOT better then then GTS in ANY category. even boosted.
If you 're not looking for huge hp numbers go with a S/C and get great torque where ever you want. if you want to get the most power you can, go Turbo.
