a friend of mine and I r doing the mpfi swap for my cus's hatch....were using a ported eg manifold, obd0 ls injectors, ls throttle body, crx si dizzy, and a pg7 ecu....wat u guys think? would it run good?

 

anyone?

 

hope this helps............................

oh my friend knows about the wiring, i was jus wondering if it will run better with the stuff were using...

 

well, porting a manifold but not the head will help, as the intake manifold is sliiightly restrictive. But not as much as if the head is port matched as well.. Think about it. big hole at the beginning, small hole at the end - You're restricted by the smallest point - doesn't matter how big you make the rest of it.

LS injectors instead of CRX Si injectors? ... they're the same thing. No difference.

LS Throttle Body certainly isn't benefiting the ported intake manifold. Refer to previous statement. Smallest point etc...

Basically. sounds like it will run exactly like stock. Bunch of mixin and matching, even some porting and I predict absolutely no gains above a normal MPFI swap.

 

that ecu is made for a dohc zc and im thinking ur gunna be running a bit rich

 

thanks for the input guys
