Will a SPFI fuel pump work on a MPFI turbo

Featured Replies

would anyone know if I can use the fuel pump from my SPFI and bolt it up to the turbo(EA82)..would there be enough pressure provided since the SPFI is smaller in diameter then the MPFI pump

It would probably work..but why would you want to use a lowgrade pump for a high grade engine?

just trying to save some money since I have a spare from a SPFI..my wife never drives the turbo car more then 3200rpm and since the rpm never goes very high and the fuel delivery is never at it's max...then I was hopeing the smaller pump would work...

It would probably work..but why would you want to use a lowgrade pump for a high grade engine?

yes is the answer.. I have the other side, mpfi turbo pump on my spfi car... both use the same pressure

The MPFI Fuel Pump is rated 61-71PSI at 1.67 Pints/sec

 

The SPFI Fuel Pump is rated 36-50PSI at 1.40 Pints/sec
