The coolant leaks are due to the X37 using a China cast bearing housing ( you know... those turbos on EBay that at $279 shipped? Yea.. that. ).
I've posted pic proof of this...
That being said... I can build an X37 for the same price as a Cyborg39. We use an actual OEM borg-Warner/ford bearing housing. We use an upgraded thrust bearing ( stock is 360 degree, but we upgrade it further ).
So if some wanted a smaller, less efficient compressor wheel, they could have that as well. If you want the smaller, more restrictive inlet, you'd have to order that from pumaspeed directly or buy one of our better ones for $150.
