B and I were talking the other day about motor swaps. 91 CRX DX = D15B2 ( D series motor) 94 Del Sol = D16Z6 (D series motor) A different D series can be put in each and bolts up no problem ie I can take a D16Z6 and drop in the Rex or I can get a D16A and drop it in either etc... without having to buy aftermarket motor mounts of fabrication know here's the kicker. Why can you drop a B Series in the Del Sol , no motor mounts need etc.. but a CRX needs aftermarket motor mounts. What's different between the two. is it possible to use the motor mounts and frame mounts from a del sol in a crx and make it possible to just drop a b series in a rex ??
