What internals do I need to change in my 12A if I wanted to turbocharge it? I want to run a blowthrough setup but want to make sure before I put my motor back together I put int he proper seals, springs etc....

 

from what ive read you should at least port the exhaust for the motors sake if your boosting a non-turbo motor, make sure oil supply/cooling systems are addressed. steel seals are fine, but get 3rd gen corner seal springs. the rest depends on how far you want to go in respects to power/reliability

 

Basically. Check the archives, there is a thread in there that has FB II (zach) setup that was a homebrew 12at that was killing everything in existence, on a stock motor.
