There is nothing wrong with maching the flywheel - it will no explode on you... they machine the back part of it not the actual wheel. Port and Polish on m20 is again probably a waste of time but yeah i'm sure he does know someone. He didn't want it done on my engine. Quote Share this post Link to post Share on other sites
