How to make gt350 imrcs work on 2018+ GT

[kenand1988]

I'll be taking delivery of the manifold this week. I'd like to use the imrcs. I've heard it's just routing the vacuum lines that is the issue but will the electrical connectors work too? Anyone with this setup care to post some photos of how you have the lines routed?

You will need to make harness adapters and get a tune to re-scale the IMRC parameters.

I could be wrong but doesn’t the Bullitt and Mach 1 manifold come with the correct 2018+ IMRC electrical receptacles vs. the GT350 manifold ?

The Bullitt/Mach 1 intake carries a part number different than that of the actual GT350 unit, so I'm guessing this would be the case.

Didn't think of that. If that is the case you probably wouldn't need a tune. Although to get the most out of the mani you would want a tune.

Harness adapters? Have you done this before? You're saying the GT wiring harness will not plug into a gt350 imrc harness?

The real gt350 mani will not plug into a 18 up GT. It will 15 to 17.

A bullit or Mach 1 manni might. I haven't seen one of these.

Dang... Wiring harness plus a bullitt throttle body. Not really worthit it seems
