well I had the d16 non-vtec n' always thought that the gearing would be awesome for boost n' now I've got a b16a in my crx but couldn't give ya an opinion on it... wating for CMS to get it back to me with the wiring done lol... but yeah I say go for it~ if you can have it done right and have the right ppl do it for ya~ boostin the d-series would be cool
