Update:
Milled the LIM, but have a bit more pneumatic work to do, but this is for the most part what it will look like at install, including milling pics, and showing the helical inserts in the core to promote thermal transfer.
The 'slits' you see inside here are twisted all the way through like twisty pasta:

Enough for tonight. I got into the Glennfiddich.
Gotta modify the core in the next couple days and figure out the milling on the bottom of the blower.
Porting this LIM will have to wait until the motor comes out and the heads come off to go the other motor for matching like the old LIM (which will be stored on the shelf until I port the SLE heads so I can store it on that car).
Then I have to port and rebuild that blower, and a GenV, then put the magic coating on both before Pdad gets here. Gotta port his L32 LIM too. So I'll be taking a short break from the intercooler work unles the meet attendees wanna work on the Zilla with me. Up to them.

This is really cool. I had thought about doing something inside the LIM void too. I like it and I can't wait to see more. Stay tuned for my prototype in the spring/summer.

Cosmetics are nearly as important as that performance crap:
My internal heat exchanger was selected for thickness and width. The length needs to be cut down in a 'staggered' fashion to fit the LIM and make the most of the efficiency:
Not as easy as it looks. This exchanger is very fragile, and re-sealing the aluminum is a bit of a trick. You can't afford leaks here. Notice the top right corner of the bottom pic? I've shaved the fins for a good fit. I machined and trimmed to make the absolute most of surface area. Thermal efficiency is paramount.

I've been following this thread, and I just don't know what to say. It all looks really good, and I'm impressed by the attention to details. One thing I saw that was interesting was the mention of airflow through the intercooler core. Is there a calculated max CFM and PSI that the fin array can take? And with that, does it mean that neither the M62 nor the M90 can outflow the airflow capacity of the holes between the fins? Also, great job as always. I thought I was free when I learned of the magic coating, but now there'* another information strain put on me. Thanks, Will!
