Hey Guys....dose anybody know how I can get hold of a new Rear Crank Shaft Seal? oh and also i raised the boost up to 14/15 psi and on boost the car sort of Stutters for a second and dives down but its only when the throttles fully open not so much when its half or 3 quaters...would that be the factory boost--cut? since then ive lowered it to round about 13lb and so far so good..but yeah any help on that seal would be great cheers
