Depends what you wanna do with your engine. If you are looking for mainly street and some good quarter mile passes, stick with the 2 litre - especially if you only want 11's. A proper built 2 litre vs stroker on the quarter is much of a muchness apparently - the stroker obviously not working as hard but its a bit lazier. I remember having a discussion with Andre from Speedtech about it a while back and he honestly said to just stick to the 2 litre unless you want to go for outright HP. Just my 2 cents - you dont have to give me any change :lol:
