Hey I need to do the MPFI swap, as I have an intake, header, exhaust aem gear, and there going to a waste with only 2 injectors. ANyways i have the pm6 ecu, ITB, 4 diff injects unknown origon so i still need the si dizzy, and relay for inj's? correct?
Well heres a question, instead of the MPFI swap can i just puut in some nice larger cc injectors and maybe upgrade the ecu and call it good? will I get as much of a respnse as i would if i did the whole swap?
thanx for your advice/comment ? ?

"upgrade the ecu"

There really isn't any support for the ECU.


"will I get as much of a respnse as i would if i did the whole swap?"

No. Having the injectors right up at the intake ports is more efficient.

 

thanks for the feedback, anyone else got an opinion around here?

 

do it right. even with bigger injectors it's still only two. don't shortcut it. you'll be much happier in the end.

 

(bump) what if I used like 350cc DSM injectors or some other large volume inj.? Also would that work with my not yet installed pm6 ecu?
