Engine Swap

I'm moving my D16a6 from my 89 Civic Si into my 91 CRX HF with the D15b5, it should just bolt on over right? Or do I have to rewire anything. Also how much of the suspension would fit into the CRX?

As far as i know it should bolt up just fine since a D is a D. The wiring shouldnt be a problem since your HF is also mpfi so it seems like it should be an easy swap. Dont know about the suspension...good luck

im pretty sure the wiring harness' are diffrent, but i think if you use the harness from the HF you should be ok.

Yeah just use all ofthe wiring from ONE car, and plug it all in..same sensors.

if you are putting it in an hf you need to change the hf knuckles or else your si axles woint fit. just nice to know before you tale the engine out.
