Okay, I just rebuilt my engine. New piston, rods, and crank shaft. Also bought a gt30r turbo kit. Because I rebuilt the engine it needs to be broken in obviously. My question is, how is the car going to drive through the breakin in period? Or will it be not drivable until the tune??

 

You will need to get a break in tune done for your required break in period. After that you can probably go ***** to walls on the tune if ya want.
