Ok, this is from much experience with all my buddies and i in the same situation (well sorta). My friend had an ls, his options were boost or lsvtec. Here is why you SHOULD NOT go with lsvtec, ESPECIALLY with boost http://www.hondalife.com/articles/lsvtechype.htm . That will explain all the lsvtec deal. Then, if you look at your b16a2 and think about putting it in, the way us racers drive these motors 80k will only last til about 100,000 til it starts to smoke. Therefor, think re-build kit for around 1k-1.5k to rebuild which isn't worth it. I would go h22a if it has low mileage. Or i would build the b16a2 and run 15-20 psi. Its all up to you but i WOULD NOT go with lsvtec. Later
