Sorry buddy, didn't mean to hijack your thread, I found it searching for something else.
-How did you determine the 2.4" pipe size after the cat to the turbo?
-How big is the charge piping from turbo to BOV?
Did CompTurbo recommend this turbo? It covers a wide range of displacement, 1.5 to 6.0 liter engines.
I am curious if anyone here has made their own ball bearing cartridge similar to how CT does theirs and this thread came up when I was searching. I wish I had the cash to get one of theirs.

It's the general consensus within the magna community that 2.4'' is the diameter of the stock exhaust piping.
I'm still unsure on that..perhaps 2.25''?
Yep CompTurbo recommended this turbo,just seems like overkill given i'm only looking for 350hp@flywheel.

I called to get a quote too and the smaller turbo was more expensive than the next size up, probably due to popularity.
So, it is a common practice with a rearmount/remote mount to run OE size exhaust tubing to the turbo? For a Miata OE is around 2" OD and the preferred cat back tubing size for a naturally aspirated engine is 2.25". I was planning on running 2.5" but I suppose the size of the turbine determines the restriction and anything larger will just slow velocity.

Has anyone considered using a power steering pump to provide oil pressure and scavenge return for a rear mount turbo?
A popular mod for Miata's is to depower the steering rack. Gives much better feel at speed and is just a bit harder when stopped. Once moving at all it gets easy. The pump can make crazy pressure when dead headed, up into the 1000's of PSI. Using a return style fuel pressure regulator should make getting 30psi possible.
Not everyone will be able to do this as losing PS is not a realistic option on some cars.

Sounds a little big. I would move down to a CT4-5862http://www.turbosource.com/CT4-Series-s/1876.htm
