GT3540 GT35R question

Does anyone know if these two turbos as sold by A-Spec have the same CHRA?

Thanks,
Alan

One is BB and the other is not..... GT35(R) means BB.

I believe the GT35R was the rename of the GT3540. Hence, it (or they) is (or are) BB.

GT3540 is dual BB. I think they are the same but I can't find confirmation.

I'm pretty sure the gt35r, gt3540r and 3582r are all the same thing and the 3574 is a non bb model with a slighty different comp wheel. Don't quote me on that tho.

All the threads I've found indicate that they're the same.

Sean can confirm it though.

Uncle henry has done his homework

Comp wheel is the same on all of them though. They all use a 3582 compressor wheel, the turbine is larger on the 3574. 74mm versus 68mm.
