exactly!! if i was on 84mm when i messed up my block it would be garbage. it bored to 84mm no problem after the walls got scarred.

Re: (MotorMatrix.com)
im wondering the same thing except on stock sleeves,9:8:1 compression or 10:1 , leaning towards 10:1 on stock sleeves, plan is to make nice power without boosting high, 12 is probably max i would ever want to run on stock sleeves, wanna daily drive at about 8, and i figure that will put me around 300whp, are stock sleeves gonna last?, it mite be either 81mm or 81.25/.5 depending on what machine shop says

Re: how much hp with 81mm (MotorMatrix.com)
what was the head setup, cams, valvetrain? were they aftermarket turbo cams?, and alot of people say stick with stock cams for the most part, but with turbo cams are you really going to see any gains that are worth justifying its purchase? i can see how the extra rpm can help spool the turbo for a larger power band tho
