All of your questions will be answered accordingly. My ka-t has a freshly rebuilt head w/ all new oem shit. Bottom end is je pistons powered by eagle rods. The only thing stopping me from pushing me 400hp is that there is a new H/G that's oem w/ new oem main bolts and studs. This is my dd, I don't want to push it to it's limits until I know it's done decently.

It really depends on how many miles there is on the block. Obviously you don't want to slap on a boost modification on a block that's high milage. Yea, it can be done, but how long it'll last is the question. Some people get the luck of the drawl, like mewantkouki.
