Thread: Doing another LIM job... what performance mods while I am in there?

Leave the blower/TB alone, the TB will require an in car tune.

Gen V does not cost $500, unless you throw your stock TB back on, which is pointless IMO.

Like I said in other thread: you can not do emissions compliant headers for $200, by the time you pay shipping and duty you're near $280. Quality cat is $200. Replace flex and its another $30-50 for the piece. The flex leaks right out of the box.

If you or one of your buddies can't weld, then you'll probably pay around $80-150 to have those two pieces installed.

Agreed on DHP PCM. Agreed on rockers as well. Suggest 105's or L76 springs instead though.

Depends on how much time you have, I would think a $50 die grinder and a $60 set of head gaskets and you could have a fully ported engine with some elbow grease, and then $200 for headers that will be easy as pie with half the top of the engine gone and get used modded 1.9's and ls6 springs, could probably get to low 13's on that.
