Model compatability
 

Does anyone know of some resources around that could tell me what parts from other cars will fit on my car?

what kind of parts do u want on ur car?

it all depends. its all different for engine, exterior, interior etc. a Integra Type R shiftboot or shift knob may fit you, but a rear bumper will not. tell us what your looking to do and we can give you more info :smilie_da

The 90 CRX is based on the EF 88-91 civic chassis.
Alot of mechanical parts are the same, suspension, engine, brakes, exhaust,etc.
Some body parts are interchangeable, front bumper, headlights and hood.
A few interior parts are the same, seats and small trim items.
This means that the civic parts will fit but not necessarily identical.
