i was wanting to know if i did a h23a head swap and intake manifold, if my dsm turbo was still going to bolt up to my f22a, dont think it will, but should i just swap the head and intake and get a new turbo manifold, or should i just leave the sohc head, swap the intake mani. and keep the same turbo manifold?

 

Are you planning to use a turbo manifold from a Mitsubishi? If so then no, it will not work. You would need a turbo manifold that fits a honda cylinder head. What do you want an H23a head? If you are going to do a turbo setup, it is not going to get you any more power.

A DOHC head will help more air enter a naturally aspirated engine, but if you are forcing the air in by means of a turbo, SOHC will be fine. I would get the correct exhaust manifold that fits the honda and GSM turbo, add the intake and exhaust piping and call it done.

 

the f22a exhaust ports are the same as the h23 non-vtec ports so unless there is a clearance issue somewhere i dont see why the dsm manifold that fits the f22a will not fit the h23...
