Where can I find info on 1985-1990 Accords and Preludes?

I'm building a circle track car. Rules state 1.8 liters or less....

I have access to a few pre-1990 Accords, and I know older Preludes have a 1.8 engine. I need to know all tech. information on the engines, and what parts interchange in each car with what years.

Any links? Sites? Parts interchange pages?

Thanks,

86-89 accords had 2.0s.
