Well you've got the hp right. A dx hatch comes with a D15B2, same as a CRX dx. The Civic std. came with a 70 hp D15B1 and a 4-speed.

thanks guys...would it help at all to just get a cold air intake and a catback exaust? or would it be a waste of time?

Not only time but $$$.

I noticed a very slight increase in power with a short ram intake on my B2. The DC catback I have did nothing for performance though. It sounds nice, but I guess the manifolds and/or cat are too restrictive to make any difference behind them. If you don't want to do a full engine swap, you can swap just the intake manifold (MPFI swap) or also the head (mini-me) for some nice gains.

The MPFI swap is a must!!!! I ran dpfi with intake, header, exhaust, light flywheel, si trans... the performance effects were next to nothing. An intake is the only sensible thing to purchase until you swap to mpfi. There is a plate in the airbox that sits on top of the throttle body. i suggest taking this out also. If you want you can use a dremmel or file and grind down the plastic inside that is sticking up also. the trans sucks too, get an si when you get a chance.
