you will need a b series mount kit from hasport or place racing. and stock hp will be just what it is/was in an integra... 140.

damn only 140 HP. i think i should just stick to my zc motor then. but the only think good is that you can go ls/vtec right?

ya but with an ls you also get 20 more lb/ft of torqu and a much better looking power curve.

one thing to consider...how much more does the B18a/b weigh than the ZC?

90-93 LS motor is 130hp as stated above. There is more torqe than the ZC, but you are limited in the revs.

I ran against a LS hatchback that was identical to mine at the drags. I ran 15.3s with the ZC and he ran 15.1s ZC. Yes I'm sure people will post better times, but as a comparison for two identical cars, decent drivers, similar setups, but LS vs ZC, that's about the difference. I think I can beat him on the top end since I don't have to shift as soon.

LS is good, but if you have a decent running ZC, you could proabably spend the same money on the ZC and get good power.

lets just establish something here. zc = 20 y/o design with waning aftermarket support. ls= limitless possibilities.

anybody know of a good source / website for building up an ls motor (without going ls/vtec)

I don't want to turn this in to one of 'those' posts, but let's make establish something else here....

ZC = much cheaper (no mounts required, no axels, no trans, etc.)
ZC = somewhat similar power from less displacement.
ZC = D series so parts aren't a problem with the exception of cams which are a little tougher to find.
ZC = nice high revs

I don't totally disagree with you. I personally could have either, and I'm in the middle of decinding which to go with. I have a ZC now, and I'm thinking of switching because once you're done with the swap, LS motors are a dime a dozen to replace, and my ZC is turbo'd and I'd like to boost more. I will say that I fear the LS transmission. I rag on my car hard, and I'm only on trans #2 (input bearing was wearing out on the old one). My old roommate drives relatively normal most of the time, and he's on trans #4 in his LS with about 1/3 the total miles I've put on my car. For now I plan on going with another ZC because I think overall, it's more fun to drive. I like motors that you have to keep in the revs because I like to drive that way. I don't like shifting at 6,500 rpm.

It's a matter of preference. I wouldn't argue that the LS is leaps and bounds above the ZC as you did though. Both are fun motors.

ya the zc is a MUCH easier swap, why do you think it is still being used so often? if b series motors went into ef's like zc's do, the unused zc's would be piling up by the boatloads. when i say the ls is far superior to the zc i say it because of its b series platform. from there you can take virtiually any route you want. tired of the ls? how about swapping in a b16, plug and p;ay baby. or maybe you want to keep the ls but need more power, try ls/vtec.

I agree. I'm still considering LS. Like you said... the possibilities are endless.
