Does anyone know if the prelude Type S crankshaft is nessesarily better than an H22a4 crank? I beleiver there interchangeable cause I though the only prelude type S was a 5th gen. Would this crank be better for High RPM?. Like if I could get my hands on one for a good price, and use it in an all motor h22a4?

Thanks
Mark

 

The stock usdm crankshaft is forged and of very very high quality. It can easily hold 600+ hp....so dont get rid of it....its the strongest part on a honda prelude

 

Type-s crank and H22A4 crank are the same.
