I got a D16Z6 VTEC in my car right now, my tranny is pretty shot though, it grinds 1st and leaks like a bitch...I think Im gonna go with the B series cause one of my friends who is a mechanic said they would put a B series in but not a H series, plus I think in the long run I could get more HP out of the B16. I just put a strut bar on my car and it handles like a champ, I cant wait to put my rims back on....then I can really test it. The steering seems to be a lot tighter also...
