Different engine.. :bowdown1:The bottom end becomes irrelevant when a restriction is reached in the head tho..But you can see why a RB20 makes more power than a RB26 right?
Why do evos make good power only being a 2.0?
Subarus also! Little 1.6 turbo Hondas...
Because the heads do the numbers... Better design etc! Rb26's heads are poor!
Bang for book your better getting decent head than a stroker!
