Supra injectors in Nissan engine

[Guest mike88ss]

Anybody here using Supra MKIII 440cc injectors in a Nissan vg or l28? If so I'm wondering if you had to make any modifications in the lower intake and the head(s) for the different spray pattern.

OOPS! I owe mike88SS a public apology for closing his post without first verifying his original intent.

 

Sorry about that mike88ss. Your thread has been reopened.

 

 

As for the injector spray pattern in regards to the L-series, (sorry, never really played with the VG engine much), the injector is so close to the port itself and aimed directly at the back side of the valve, the injector notch machined in the head will not be in the way of the spray pattern. In a quick search for Supra 440 injectors, it appears that many other guys ARE using those injectors with no issues.

 

Here is a picture of an L-series cylinder head with an OE intake attached, looking straight down the injector boss port and the back side of the intake valve can be seen.

 

 

 

This pictures sort of shows the machined injector notch, untouched port on the left.

 

 

 

In this picture you can see the orientation of the injectors. The manifold on the right are the OE injectors, to the left are Ford 4.6 modular O-ring style injectors, (the injectors themselves are just barely protruding out of the manifold, hard to see), with a much wider spray pattern than stock. That intake is up and running with a Wolf EMS, and 6 GM LS-x coils on an L-28 currently.
