My 2019 Bullitt came with a GT350 IM. I’ve never seen a 2015-2017 GT350 IM off of a car, therefore, I don’t know whether they are the same. Here are some pics to show what my Bullitt IM looks like.

Didn't realize you had a Bullitt, my understanding is that the Bullit and Gt350 manifolds are identical but that the Bullit has updated IMRC connections for the later model wiring

I know nothing about the differences. I initially took my IM off to access the two top transmission bolts, but figured hey, while it’s off, I should at least consider doing some enhancements to it. Here are pics of the Bullitt IMRC components.

Note: When I ordered the IMRC lockout kit from MMR, it referenced using the 2015-2017 GT350 part number. I sure hope they fit.

Well that clarifies that! Nearl completely identical and uses the same connector types. Only changes seem to be a little reinforcing

One thing I haven't seen is, what any of the known porters have done to the IMRCs. The pics that I’ve seen posted on their sites only show around the injector bosses. It would be interesting to see what, if any shaping they’re doing to those.

Only difference is 1 has digital electronics and the other has analog electronics.

That’s just the signal, i had previously thought the physical connections had changed to the 18+ style but they didn’t.

They just do the port like they would on a non-imrc manifold. Flap fully open and port shaped. They don’t change the cutout of the flap though.

when i ported my 18 i did the porting then filled in the gaps from the imrc's and smoothed it out so it was like the imrc's were never there. just smooth runners

Now that sounds like some attention to detail right there! Did you by chance take pics of it?

Did you fully remove the rods and flaps then? I’d be curious how that worked out

no you epoxy them open and port them

 

[Jackson1320]

you see all the high and low and lines they all get filled they ported and if you want polished but you don't need the polish. normally you can still see the imrc's even after porting. this was a 15-17 intake

Do they offer the all open port commercially?

Like for sale to common consumers?

The current gen 2 and 3 are all open port. The CMCV's swing out of the way. Nothing blocks the port unless they are currently active.
