To my knowledge the Euro M3 motors are not even in the same engine family as the US stuff. Sure the S50 is a bored and stroked M50 but I don't think you can compare it like that. The Euro M3 engines have more in common with the S54 than the S50/S52 of the US. I could be wrong.Originally Posted by speedminded
Either way there is a tuned S50b30 and lots of CF in that ACS car. it has 3 racing seats also.
2 in the front and 1 in the middle of the rear. It is a 3 seater IIRC.
