I just bought a little project CRX on the side. Its the DX model. The difference between the DX and SI is the engine and transmission. Ive been reading up on the DOHC ZC swaps. For the ZC swap you need to switch dpfi to mpfi if your working with a DX. To put a stock Si engine into my DX do I still have to go through all that process?

 

no..You can use your dpfi manifold on the si motor..But thats stupid..
And the motor will not be used to its full potential

Just convert to mpfi and get it over with now..
Alot better then dpfi

 

This man speakes the truth, go ahead and convert, you will be happy you did.

 

Can I convert my DX from DPFI to MPFI without putting a different engine in it or do I have to put it together with a ZC or SI engine?

 

Yes,you just have to get an intake manifold,
resistor box and injector clips,and its wiring from a D16a6..
[Look in the FAQ section at the top of this forum for links]

 

hardest part of the mpfi swap is those damn ecu pins UGH

 

edit wrong link:
This site shows how to do it:
