hi, im looking for something.

i got a b21a1 its a 2.1L, in my 91 prelude, with an automatic tranny, and it has 207k miles on it, i was just wondering what other motors could be put into my car without completely having to alter everything. i was looking at a rebuild kit for about $400 without a new head, adn the head would be about $500, plus i need someone to put it in for me. can someone help me?

the best thing for you to do would be to put an h22a in which involves only small mods like wiring a couple things in that the 91 didnt have also you could go buy a b20a5 which is the other si motor thats what i have its the better of the 2 motors. the b20a5 has a low compession too so you could turbo that thing and be fast and reliable. but the h22a would probably be the best choice because of the base horse power and you can turbo that if you can find room for the turbo.
