EFI Injector Sanity Check
 

Hello,

I’m in the process of building a 3.0 EFI conversion with a turbo. I’m in a bit overwhelmed by all the different fuel injectors out there. With that said, need a sanity check on whether this injector will work with my setup. Based on my HP goals and the fact it’s a turbo, I’m planning on 60lb injectors. Below is the injector I’m planning on buying. Will this injector work with my setup?

Here’s my setup:
MS3 Pro
Carrera intake and fuel rails
Aftermarket FPR

You're right to double-check before buying injectors — selecting the wrong ones can cause major tuning headaches.

Those injectors have two spray cones, one for each intake valve on a four valve engine. For a two valve engine they wind up spraying a lot of fuel at the port walls. A single spray cones would be better. The 60 lb spec is fine. Check out a Siemens 107961.

Good point. I’ll make sure to look for single spray cone type of injectors.

I have a set of 60# Siemens I used on my 930 before going bigger 100 for all 6 shipped

It really helps to know the actual injector dead time and other timing parameters when trying to tune low load running, like idling. Finding this information for a set of injectors is not always easy unless the manufacturer provides a data sheet or you send them out to be measured.
