I would like to know, if it would change something by changing a H22A Type-S Motor Head, by a B18C Type-R One? Would the torque be better? HP? RPM?

Because a B18C Type-R has a 10:8:1 compressiopn ratio, when the H22A has 10:6:1. And the B18C has a redline of 8900Rpm and the H22A has 7200Rpm.

Would it change something? Or it would'nt change nothing at all?
