Performance mods 3.8 N/A



a turbo, intercooler,tune, and a built trans.

Other than that you're not going to get much for the money spent modding the N/A engine.

how would he ever get a comp g tranny to work when it wont work in another 04 up gp or gtp?

he could get a l67 and hd tranny and drop it in tho. with tuning. but being the fight we just saw in the other thread how ready are you to really rip open your engine? or do a swap?

your n/a, just deal with it is the best advice. or sell gp and buy a gtp or better car.
 




Plog and downpipe with a tune to match.

That will add a little bit of power, kill stock kr, increase mpg maybe, and allow the engine the run/breathe a whole lot better.

A step further would be the hv3, but you would get better power/$ with boost instead.
