I can't tell if its F rev or not, but it looks similar...

Quick update:

This is now an available upgrade through GPOP Shop for the following prices:
- Full IS38 internals upgrade (compressor + exhaust) @ $695
- Partial IS38 internals upgrade (compressor side only) @ $550

This includes teardown, machining, balancing, and rebuild.

Dunno about specs, Jay didn't post yet.

What kind of specs are you looking for? Inducer / exducer are exact is38 spec, and the recommended efficiency range is 18-22psi at redline.

Gpop did not provide a ton of detail, as this is currently 1 of 1 without any field testing.

Ported and polished, ceramic coated, and full is38 internals ran me $915. Just the internals were $695, but I figured I would have them do it all while it was disassembled on the table.

Do you feel the ceramic coating is necessary? I mean obviously to a degree you do, just wondering how much of a functional benefit it provides. Thanks again man, super pumped about this being an option for us now.

Honestly, I don't think either the p&p or coating are going to be game changers. I think they will help a bit with spool - maybe peaking 300rpm sooner between the two of those.

$915 great. I assume it is balanced? Any plans to dyno or track it? Thanks

Yep, balance is include as part of the upgrade cost.

I'm definitely going to dyno it in a couple weeks - install is next Friday, and I want to get it dialed in with George before it hits the dyno.

Get a base before and after to see any difference

I have base dynos from my no-tune FBO run (220whp/275wtq), daily map (270whp/315wtq), and high boost map (285whp/315wtq). I'll run the dyno on all 3 maps so we can see the difference at varying levels of boost.
