I'm cleaning every part that i'm takeing off of the old motor and new motor, almost every part. I was told by my dad to, for the fact that a clean motor and clean parts will last alot longer and keep this motor in awesome shape for years to come. 2k was a rough estimate I will be spending more on a new things. I'm cutting off my fartcan and putting on a stock Si muf, if i can find one, also I bout some new seat for my car and going to get new stiffer mounts for the motor and tranny. To much to list right now, but will have a list after i'm all done for you guys..Peace Kov
