MPFI Swap CRX

[UfoTofU]

Would I only need the air box and the tube from the airbox to the IM from the Si or would I also need the resonator and air intake tube as well?

You should only need the intake arm. That's all I needed.

[UfoTofU]

Just from the intake box to the IM?

[SVOboy]

Yep.

I have an IM from a '92 Civic d15b7 engine, it has the injectors.

The IM that I got from the '88 CRX Si also came with the injectors.

Would I be able to use the '92 injectors in the IM that I just recently got from an 88 CRX Si and bypass the need for a resistor box?

I ordered a resistor box off a guy on honda-tech. Gathering pieces for my MPFI swap in my 88 CRX DX. I currently have :

- 88 CRX Si intake manifold
- 88 CRX Si ECU (PM6)

He sent me the "Silver Twinkie" style one rather than the boxy one on the left.



Can I use this one or do I need the other type? Hard to see in the pic but the one on the right has a "95" printed on it. Hopefully that doesn't indicate the year because I am pretty sure that I need a resistor box from an 88-91 Si or 88-89 integra.

I think the twinkie style is the original, but I'm not sure, I'm not using one. You could always test the resistance.
