    ls vtec is the way to go use b16 p30 pistons in it with a b16 head and u will yield some good power

    ^^ May also consider swapping to a b16,GSR, or type-r trans as well it will help. What's your budget? reason I ask is that you may be able to turbo the car for the same price as an LS-V done the right way but you will yield more power with turbo...

    i would keep that engine since this is why u bought the car.. get some vtech killer cams underdrive crank pully and port n polish ur head. maybe bigger injectors.. tht will help some prolly a gain of 15 hp maybe even more..

    In Cali head swap are illegal, just build the motor up I.e. Rebuild it for higher comp etc.. Or just drop a gsr/b16 in I woul recomend the gsr over the b16

    Here are two good articles for info (both in the Ref section)

    http://hondaswap.com/general-tech-articles/build-reliable-ls-vtec-85477/

    http://hondaswap.com/general-tech-articles/building-ls-all-motor-monster-31401/

    I agree with red91efhatch, swapping the tranny would be a good idea for quicker acceleration. It's also much easier to do then rebuilding a motor.

    op: as far as transmissions go what people sometimes do is take a gsr/b16/etc trans and swap in a ls 5th gear.

    and you'll either want to ls-vtec and/or boost it as it is if you want to get some power out of it.
