I am wanting to upgrade my 02 monte ss to above 300 hp, i hear once I get to about 350 hp im going to need a new tranny to hold the torque.
so far i've put a custom intake with a k&n filter. very little I know but its a good start.

any suggestions?

yes yes I know cartuning turbo and an intercooler will get me there in one shot but I live in canada and it'd be about 6k just to get it up here and installed.

I wanna go cheaper.....


Thanks guys.
