Hi all!!!

Does anyone have any pictures of their G64B that I could look at??? First time working on these motors and I am a bit confused. Also there are anyone here that lives in Seattle, Washington that could give me a hand would be great. Thanks everyone!

I have a 1990 L300 with 4G64.

Since you have the G64B, the main difference should only be that you should have a MCA "Jet Valve" head like the Starion. The other differences, if any, should be very minor between my 1990 and your 1987.

The other main difference that I understand is that the 87-88 L300 used LOW impedance fuel injectors. The 89-90 used HIGH impedance injectors.

I would have to look, but assuming that the wiring harness has the same pin-out and only difference is the injectors, then you should be able to swap the computer and injectors to something from a 89-90.
I use the "blue top" injectors from the mid-90's 2.4ltr Eclipse (also other Mitsubishi 2.4 ltr cars come with them, i.e. mid-90's 2.4ltr Galant) and I am running on the ECU from a 1990 Mighty Max. The 1990 (I think some early 91's maybe) Mighty Max is the only year that had the same injection system as the vans.

I would advise you to have the fuel tank reconditioned with a van of this age. Also, new hosing, filters, etc. would be advisable. If you reuse the stock fuel pump, be sure to get a new pick-up screen. And if the mounting for the pump is rusty, then have it taken apart and reconditioned with the tank. You can also convert the pickup tube in the tank and go to an external pump like I did (see me if you really want to do this).

As for the hoses, there is a way to use new hoses on the old screw on hose fittings in the fuel system. I can show you how to do that.

You can also use the engine from a 4G64 powered Mighty Max if you need to.

I can advise you on matters pertaining to this van in USA-spec. Let me know.

I also have a 1990 Mitsubishi VanWagon with the 4G64.

Where is the pickup screen and any other gas line filters located?
thanks
