i got all the parts for the MPFI swap minus ecu and dizzy (getting those in a few days) i noticed that the manafold had a PG7 on it and the rail i got with the obd1 injectors dosent fit.

here are some pics:
this is the IM



and here is the aliment of the holes with the fuel rail on it. it's not on all the way as shown but it's allinged with the injectors in the right holes.



i also got a fuel railfrom a 90 SI but it didnt even let the injectors line up.

what am i doing wrong?

 

PG7 - Either a D16A1 intake manifold or a DOHC ZC intake manifold, either way, the bolt pattern is different from standard D-Series Intake Manifolds.

EDIT - I pm'ed you about MPFI parts.

 

thats a dohc zc manifold. it will only fit a dohc zc. you need a Dseries one, I recommend a d16y8 manifold.

 

do all IM's have that number? so i should look for a PM6, PS9, P28,etc IM right?

 

bump

 

pm6 would be your best bet, you could use a y8, z6 etc. but the a6 or y8 are probably your best bet. i believe ps9 is the code for the dohc zc.

 

I bet you its a D16a1 manifold. Look at the angle of the TB. My DOHCZC manifold was the same size, but not angled. Never seen any angled except on the D16a1.

yeah. same thing otherwise.

 

the ZC manifold i just bought reads PM-7 and has alot bigger intake runners and the body is bigger too

DOHC ZC is PM7, that intake is from a 1st gen teg motor d16a1. You can usually goto a junkyard and get tons of PM6 manifolds off the 88-91 CIVC/CRX SI/EX.
