I am however using T25 Plus vband exhaust housings, not the internally gated 5 bolts so it might change the location slightly.

Hmmm...well, we fit a pair of GT35R's without modifying the engine mounts on either the HR or VHR and the 35R is a much bigger turbo altogether. Granted we have our own custom turbine housing, but the 35r's compressor housing is way bigger than the GT28's. What part of the compressor housing was interfering on your project? Did you clock the turbo before trying to fit it?

After going back and forth with a Garrett engineer, he assured me that the external dimensions of the GTX2863R compressor housing isn't any different than the regular GT2860RS. Given that information, it would be pretty safe to say that it would fit, which is why I am asking about the clocking of the turbo on your project.

Our Turn-Key turbo kit uses an adapter to go between the turbine outlet and the stock cat as it always has. Nothing needs to change there.

For those of us who have your first TT kit, would swapping just the turbo make our kits CARB legal now? Basically, what else is needed to make the non CARB legal kits CARB legal? Very interested in this.

There's a couple other minor changes that will probably need to be made. We'll make the necessary changes as we go along. I'll have to look into the possibility of a "CARB conversion kit". Just bear in mind that we're at their mercy to some degree.

We have not received the test letter for the application yet. Once we do will proceed to the next step. The delay in getting the test letter worked out to our advantage sense we have learned so much in the last six month dealing with our supercharger kit approval process . The supercharger kit car is going in for testing next week, if every thing goes according to plan we'll move our focus to our TT application .

I know this probably isn't right place to test this but how'd the supercharger testing go this week?
