I had a 93 Civic Si that I put a H22A1 into, blew a rod out the side of the block, then put a H23A bluetop in. Rediculously fast.... The benefits of doing an h-series would be the better pricing on engines and trans, an easier shift-cable setup, and the base of a large engine. The drawback is that the engine has FRP sleeves, there in making boost nearly a no go. The electronics situation doesn't change, though. Well other than the fact of wiring in another actuator, the secondary butterflies.
