All of the top dsm guys that tried both strokers and 2.1 ltrs came back to the 2.0
There is a certain well known person in the dsm world that swore by the 2.4 for years.
Well he finaly got tired of grenading parts and put a high compression 2.0 in and the car went .4 sec faster than it ever went on the stroker.
This is a 8sec awd just to give you a idea of how significant .4 sec is.
