MPFI conversion

[deerhurst]

Hey, be it been a while. Lots has happened to my truck since I last logged on. I lost the #1 piston, a chunk fell off on the highway, and decided to swap in a VG33. Right now it is set up as a TBI motor. The motor is a JDM motor. It feels much different from the USDM motor in my aunt's pathfinder. It runs really good and will spin 31s through 3rd with a 4.11 rear end!

 

Needless to say I run out of fuel on hard pulls and when pulling hard up a hill with a trailer. The TBI unit is struggling. I'm thinking of changing it to MPFI with the intake, plenum, fuel rail and injectors that came with the JDM motor. I assume they are 180cc injectors and would prefer some 320cc supercharged injectors for later plans (M110). I know nothing of the JDM spec.

 

Talked to JWT a while back and the guy I talked to essentially suggested to run my own wires for the injectors, Repin the connector and run a Z car ECM with a tune.

 

Anyone done similar? I'd love to stay all nissan and stay simple.
