I want to do a DPFI to MPFI swap on an 88 CRX DX, but i need to a couple of things about my motor because i think the prior motor was taken out before i got and whoever had it before me got it running, and yes i did do a SEARCH but does not help out my particular situation and could not get a clear answer.

Question#1:My Head has a stamp of PM 3-7, what head do i have?
(when i did search the closest answer i got was a D16A6 Head, is this true?)

Question#2:What Dist. do i have? And will it work with a MPFI swap?

Question#3:My block is D15B with 1669502 underneath, is it USDM or JDM?

Question#4:My friend gave me an HF head with IM, can i use it?
(i'm guessing i cant because it's HF and redline at like 5000rpm)

Thanks!

 

Nobody huh? TTT

 

If you are running dpfi right now then your current distributor is not gonna work with the mpfi swap.
