...i need some swap info for a friend...tried the search all it brought up was civic info...anyways my friend is buying an 89 Si w/the b20...the heads are warped and he needs some help. he's looking at a couple different options right now: swap the h22a, swap a b18c1 or c5, or new heads...on the h22a swap what exactly is needed? on the b18 swap what exactly is needed? and on changing out the heads i've heard that you can make a frankenstien engine by putting the b18 or h22a head on the b20 block...is this true? if it is would putting together an engine be easier and cheaper than getting the whole engine? thanks for any help/info you can give...
