above is a list of shit for 3rd gens. the h22 is very heavy for the 3rd gen chassis, there are a few people that did it, but i wouldnt do it if you're going to keep for a few years. it will eventually "wear out" the chassis. the jdm b20a has about 143hp (dont sure the torque) but most people do get it for about 600. the b21a1 is a good motor to turbo since the compression is something like 9:5:1, it's got one of the lowest comp. ratios for honda. another option is the b20 block overbored to fit b21 pistons and a b21 head, then turbo. pretty much a b21.
i've heard that CTR pistons will fit, for higher comp. maybe?
i've also read that h23 rods will fit, for stronger rods
and most b20a5 to b21a1 and b20a parts are swappable. (cranks, rods, heads, etc...)
the oil problem in the b21a1 come from the piston rings. replace them and your oil problem stops.
if you'd like more info check out
www.preludepower.com, its a good forum, mostly arguments and "ricers" but some of us can try to help you out. after hp.com went down we lost a lot of members, and now that preludeonline.com is a pay site now, it went to shit...
