vr4 injectors

[4g6beat]

I've got a few spare parts lying around from doing up a vr4 (injectors gearbox piping etc) and i was reading that i could convert the starion to mpi with vr4 injectors (and of course other things).

What do i need for this conversion? i've got a spare old microtech digi 1 lying around. i'm assuming i'm going to need fuel reg fuel rail and of course an inlet manifold will a jb dizzy be able to handle spark if i do this?

thanks in advance for any help with this.

Easiest way.. L300 intake manifold bolts straight on. VR4 injectors fit straight into L300 fuel rail. Use the L300 fuel pressure regulator.

How you control the fuel and ignition is upto you. You can run the factory ignition and use a fuel only ECU if thats what you have. Prefered method though is to lock the dizzy and run a fuel/ignition computer or go for an optical dizzy and multi-coil arrangement.

What he said.

Do you have a Digi 1 or a Digi 1 Pro (fuel and ignition)?

If you use the jb dizzy, you wont be able to have the microtech control the ignition. An optical dizzy is the usual easy fix for this. L300's and some dash motors had them, they are old so a new sensor along with the corect disc will be needed.

Why not Chef?

Hi nxtime,
Yeah I've got a standard digi 1 for now.
I'll be looking to get an e6x since i'm used to them and my adam from JEM is a bit of a wizard with em but for now it looks like all i've got :)

Yeah, ok, you'll have basic ignition control. what was I thinking

Probably about your next weird and wacky under-bonnet modification. :)
