why dont you do some research in the engine tech forum? oyu waste space with questions like this. and yes, i am the one who will be putting a ITR front end on my civic, not easy, but a lot less headache then trying to suggest an engine for someone else. but if you want my 2 cents, a b16 with a moderate amount of head work and a little building of the block and you'll be fine. If you want to road race, i'd be more interested in a good suspension settup rather then a 200+ horsepower motor.
