400 turbocharged D150

Post by cw25 » Wed Sep 16, 2009 7:50 pm

Always wanted EFI on my turbocharged truck. The cold start and drivability of EFI is far beyond what any carb can deliver. I had one issue that bothered me with going EFI and that was no port injected manifolds avalible. So I made my own

Specs. MSII V3.57 60lb injectors

I drilled the holes in the manifold with a hand drill touched them up with a rotary tool. I used JB weld to hold the MSD epoxy in injector bungs.

The manifold finish painted with the bungs and rails installed.

Mounted the MS behind the seat.

The first pass with MS controlling everything. :yeah!:

That weekend I was runninga about 4lbs of boost and ran 12.64, 12.36, 12.36, 12.39 and 12.37. The first pass was off idle. The last 4 were launching at 2200 rpm. Who says that turbos aren't consistant.

How are your injector bungs doing after some time?, are they holding no vacum Leaks? I´m planing on making my own manifold but I was going to have them welded (it is expensive) if the JB weld holds for long (never thouth of it) I will ever thank you for this tip (and the pocket savings,) by the way, very nice set up, good looking old mopar truck
