Does anyone know if an 86-87 Integra (vac advance) distributor will work on an 87 Si D15A3 engine? I may be able to get one of these for pretty cheap, and I think my stock distributor is going on me. Also, while we are on the subject of interchangibility, How does the Integra's intake manifold and throttle body line up? I would guess the intake manifold would be screwy because it's a ZC pattern, but will the TB mate to my Civic's? At that, is there even any difference in the bore? I'm looking for cheap modifications right now, just stuff to help build my knowledge of 3G's.

 

I don't think the distributors or intake manifolds are interchangable. I'm not sure about the throttle bodies. The 1G Integra bore is 1mm bigger than the 3G Civic (75mm vs. 74mm).
