Your not listening to me. ZC, DOHC... from japan. With a D16A6 transmintion.... Its verry fawking simple! Dub got it, why cant you? The ZC and D16A6 have the same top speed ok, one has less RPM's that would be the D16A6... So does 500 RPM's make that mutch of a diff? Yes and no, its the 500 Rpm's + the longer gear ratio from the D16A6.
