We just found out about this S21T Buggy Engine meant to be the contender for 2008 races. It is a very interesting new design especially on the head. We talked about the STS D21T MKII RBmod and we thought it is the same. It is not. It is a new design indeed. The crankshaft is different, the head obviously, and even the porting on the sleeves are different. So check it out here.
