I'm in the process of making a list of everything I'll need for a build. I'm planning on going forged internals and was wondering what compression is suggested if I'm going to be adding a D1SC? Also, the previous owner changed the gears to 3.27's. He said it was because he was planning on supercharging it, but never did. I've got some 3.73's I never got put in. Would it be better to keep the 3.27's or go 3.73's? It's an '04 automatic with around 86k miles. I'm wanting to get the highest #'s I can without pushing the motor.
Thanks in advance!
