I will just jump in, and say its not a ball bearing unit. We have found through extensive testing that to retain the spool N54 owners look for, you have to size turbos on the smaller side, this means elevated shaft speeds. Adding a BB to the mix means you have now added a very real upper RPM limit that did not exist in the JB units. We will never offer stock location, stock type casting BB units for these cars. You are opening yourself up to failures while picking up very little in the way of decreased spool time. We currently do offer BB turbo upgrades for the N54, Stage 3 kit uses twin Genuine Garrett Ball Bearing units...
That's some good info. Thanks for that.

Are the new N54 turbos going to be better than the GCs? Or just a another option?

They will be equal to or better than current GC's, with some changes. We always build on what we learn, and make things better if possible. We will make a full announcement on the units in the near future.

The new shotgun kit looks awesome Tony, cant wait for the new revision.

My engine is getting rebuilt as I write this and hopefully the new drive kit will be available by the time its ready for install.

My double barrel is awesome and supplies all the fuel my engine wants and then some.

Moving away from pi is the best thing I ever done, and when I let my wife drive the car and leave the traction control on
the car doesn't buck like an angry bull anymore when it kicks in..

Car drives like it suppose to, silky smooth.

Best money ever spent.

Tony/Chris do you guys have any issues with car running rich with a Dual Shotgun kit?
would we still need to do a FPR and a RETURN LINE?
or does it depend a lot on the LPFP setup?

Looking forward to seeing what this aluminum hotside charge pipe looks like. So much so, that I may hold off on installing my GC Lites until I get one in hand! I have the silicone version, but I know that will leave me permanently paranoid even I have them installed correctly.
