A H22 motor is relatuvely cheap. A sohc on ITB's takes a little more dedication. There are not many companies out there that make a direct bolt-on ITB system for the SOHC motor. Most people custom make thier own, using Motorcyle throttle bodies. Here is a link. with some info. http://www.d-series.org/forums/showthread.php?t=2957 I really do not trust anything that is fabbed up to fit something it wasnt originally suppose to fit. So in the end I would recommend that you do the H22 swap. in the end you will have a better running, more reliable car. Thats has mor HP and Tq than the single cam. And this is coming from a person who loves ITB setups. Good luck with your decision.:thumbup:
I think the H is too much if you want to take it arond turns. If it was me I would do a K, B, or D. The D with ITB is cool... and you dont have to make some thing fit its all redy there lol. Well good luck for what every you do.
