    Default 1991 CRX HF--SI swap

    Im finishing up this swap in my crx that the previous owner started. Right now the car has the d16 engine but is still using the HF intake and computer. I finally got a complete SI intake and computer to install onto the engine.

    Is there anything tricky I need to know before I finish the project? are there any other parts that I will need to complete the coversion? (ive got the complete intake (minus a broken TPS) and computer. should all the vacuum lines line up to the SI intake? Im going to go buy a chiltons maual before I start, but would also just like some info from your experiences.

    it should be plug and play, The HF uses 1 extra plug (the EGR) that the Si wiring harness doesnt have other than that its identical.

    For the vacuum routing use this or basically it will be the same routing as the Si...
