These turbos are not ball bearing turbos. The vette kit think has more expensive bb turbos but this kit is using conventional turbos modified mitsubishi 20gs. They are still a good turbo very reliable and sure will still spool up plenty fast on our big v8s. You will lose a bit of spool between shifts over a bb turbo though.
So these turbos do not need oil restrictors like bb turbos do and possibly some oil feed only garretts.

C6 uses DBB turbos, C6 Z06 uses I believe GT35R DBB turbos which are pretty ******* awesome.
C5, GTO, and F-Body all share the same Mitsu 20G turbo.
Would be nice to see GT35R DBB turbos as next years upgrade turbos, but i'm sure the Mitsu will be great as seen on many GTO setups (not yet seen on C5 vette setups)

So I decided to pull out the digital calipers and measure my own stock TB and the NW TB. Stock TB O.D. is 3.95 inches (or 100mm) and the Nick williams is 4.0 inches (or 101mm). so there is a 1mm or .050" difference between the two for those wondering

Ok I stand corrected .Guess was reading the c6 stuff. Anyway yeah those are BB types and 20gs are not bb. I am very familiar with this turbo stuff. Have a big garrett on my 97 talon..sort of a gt30/gt35R cross. and have lots of experience with other mits turbos. The talons use smaller 14bs in the older models. Fairly reliable but at about 100,000 or so miles they are pretty much done but that is fair amount of mileage. Ball bearing gives usually faster spool up and holds between the shifts better. It is also more pricey and don't think rebuildable. I am not overly against the 20gs two of them should still be pretty formidable.

I was just curious if anyone foresaw a potential problem with the turbos seeing 65+ lbs of oil pressure. I have heard of (and seen first hand) how big a pain in the *** it can be, if you over-pressurize a turbo with oil. I just don't want to be cleaning oil out of my intake.
The only reason I really brought it up was, I was reading through a ton of threads earlier this year....looking at problems people have had in their forced induction setups. Just trying to learn from others mistakes and not duplicate headaches if possible.
If Peter says they're good...that's good enough for me.

My current motor pins the gauge when cold, and over ~3000 rpm
Stock pump, not ported or shimmed.
It calms down when warmed up though, idles around 45psi hot and 58psi on the money at cruise.
