What's your price range?

It seems like you want something with vtec, be it sohc or dohc. If you want to be cheap (under $700), I'd suggest getting a d16z6 or d16y8.
In my opinion, sohc vtec isn't that great and you'd be better off with a dohc non-vtec motor.

If you don't mind spending about twice as much, you can probably get a b18a (90-91 integra rs/ls/gs 1.8 dohc non-vtec motor) with complete swap for about $1200 or less and then you would also need seperate aftermarket b-series mounts. The motor makes 130 hp and 120 tq.

I think you'd be better off with it. But for the price, the d16z6 or d16y8 might be a better deal.
