So i've got 165k on my stock motor right now. i realize boosting that is asking for trouble. What are some vital internals that I should be replacing/upgrading to boost this engine? Not trying to get maximum HP here, would just like a little more power so my car isn't so pussified...just looking maybe 7psi ^_^

 

if 7 psi is all, do a compression test. if it comes up good, boost what you have. enjoyit. then later if you develop issues, do rods and pistons, with engine management. and again, enjoy it.

Yeap do compression check. Leak down test is better. What's your whp goal? if you're shooting for 250whp and less, you're fine. Remember, stock internals are limited by whp not psi, so you can run small t3 with 10 psi or t3/t04e with 7 psi; they put the same amount of stress

 

if you motor has good compression you shouldnt have any problems. im running 10 psi and my motor has just about 210k on it

 

i would rip apart the bottom end and replace all the gaskets seals bearings and all the important things, but thats just me.
