whats up guys,
im new to this whole turbo thing and a few of my buddies have boosted cars but they are always having problems. first let me start by saying im shooting for 300hp so any advice would be appriciated. my motor has about 90k on it still runs strong dont smoke an only uses about 1/2 quart of oil between changes. i do plan to change the valve seals while the motor is down. im eventually going to build a bottom end but probly not til next yr, and ive always been one to live by the if its not broken dont fix it moto. so the questions i have are.

should i change my bearings in the bottom end or just leave them alone?

should i change the oil pump or is the stock one fine?

i was thinking about buying a set of stage 2 crower cams...is it worth the money?

 

depends on what your gonna want in the future, but extra insurance isnt gonna hurt you. I would hold on the cams till you build the bottom end next year. imo
