will a dizzy from a 86 fi accord fit in a fi crx?

Nope.

I've checked out Accord A20 motors looking for parts to swap, and have found that there are no parts that will fit on a Civic D15 without modification.

o, was jus a thought

what about off the older preludes?

Not sure, never checked. My guess would be that it wouldn't. Do you need a distributor?

i do, i can get one but dont feel like buyin one jus yet, so i was seein if any of the others would fit so i dont have to pay for it cause my buddy owns a yard n he crushed the other rex's already, so i wanna see what i can come up wit...
