A little birdy told me...

...That there is a 2015 based turbo with a modded center section GT4202 stuffed inside of it, and it's out on the streets for testing. Initial reports are that it's very promising.

For sizing reference, a gt4202 is roughly 74mm 102/82

It has a comparable compressor map to a s475 (between a 83mm and 87mm turbine)

Would the back pressure on a large VGT be an issue with these 6.7's like it is on a 6.0? I know we got a lot more head bolts and all but at some point would it still blow a HG?

morgan@midwest is proving that they'll live with proper tuning with a larger VGT. A wastegate is ideal too.

I've been working with Matt@gearhead as well dialing in my 2015 turbo swapped 2012 6.7 and we're sitting at 36psi right now with very good results so far. He has the vgt cycling down pat and the truck is VERY responsive and very clean. I'm about to add a wastegate to my set-up and continue tuning and testing.

I'd buy one for my 2015.
