^I'm curious to see how the GTX performs, but me personally, I'd have a hard time spending that kind of cash and not just going for an EFR.
On another note, anyone else have issues with wastegate cans leaking? I'm on my third one. Each can can deal with 14psi for a few weeks, then they suddenly seem to start leaking boost from the diaphragm.

@SpartanSV ATP is offering the GT2x turbos in a T3 5-bolt Ford turbine housing. It "should" drop in to an MK setup.

Overall I think an EFR is a much better use of money over buying a Garrett turbo at this point in time.

Does this look like a problem to anyone else?

I'd do the .63 given the smallish size of the turbine wheel. If you're going BB, then maybe even the .86. It's really down to a preference of low end spool vs. top end flow.
The GT is a nice improvement over the T, and the BB upgrade is definitely worth the $135 up-charge IMO. But then you're at a grand for a turbo that is, at this point an older design. Like Lars said, the EFR is up on another level. I only recommended these ATP GT hybrids with the old T3 turbine because it was a straight drop-in and ATP's T3/T4s were only $100 cheaper (and too big). They used to be $500 turbos.![Dunno](https://www.miataturbo.net/images/smilies/dunno.gif)
Where's our Garrett expert? @JKav

Saw that and was equally confused.
From what I understand, T3 .48 = T25 .64? Does that make sense? In that case the .86 would spool horribly even BB.

Except that the GT28 turbine wheel is smaller than the T3 wheel he's replacing. Add to that a more efficient compressor/wheel design and maybe BB. I went from a .48 to a .63 using a large Stage III wheel (55.88/ 65.02mm). I changed to a much larger intake manifold plenum, 65mm throttle body and EWG - my spool improved. Also consider the T3 turbine inlet is significantly larger than the T2. The wheel(s) design/size makes a much bigger difference in spool than the AR size.
