I have been keeping up with this thread since I am very interested in th N/S S/C. The only problem is that they don't have one for the Throttle-by-Wire cars yet, does anyone know when they will be out or know a number I could call. I have written several emails but have yet to hear from NS.
Also is it suggested just to order the high alt. version with the 2.6" pully right away?
The DBW has been hung up in C.A.R.B approval. Apparently there is a new test that's been added the checks for emissions when the A/C is on. The GM lab that Neuspeed uses is shutting down and not taking any more orders for testing. The BMW plant (Chatsworth?) isn't certified yet. So they have to find a lab to test the car. From what I know, it's ready to go except for C.A.R.B. and being in Cali, they can't sell something that isn't approved.
Living in VA, you would be fine with the 2.6 and that's what I'd recommend.
