| Awesome man. Welcome to FI. How many miles are on the car?. What type of transmission and differential do you have?. None of this should matter quite yet if you keep it at low boost stage 1. But if your over 100k miles I would recommend new rings on the pistons and a metal had gasket to stay safe. I would also recommend if you have an auto get a 3.64 diff from a Z4 for the heat exchanger. Just run rich and you should be a ok. I would worry more about the drivetrain then the motor anyways if over 100k miles. I would also put in new rear trailing arm bushings and differential mounts.
