What was the inspiration? Factory turbo racing photo reply
Actually, somewhat yes, the factory racing turbos were (as I recall) 270 hp and had very exotic cooling systems.
I just wanted a high specific output 6 cyl with the minimum weight, thats what drove the M54 motor selection. The trans was a wild idea to get the best weight distribution and I wanted a bigger technical challenge than the coupe (relearning "be careful what you ask for......) . Two turbos, engine management and a transaxle seemed tough, but do-able, in bit size chunks. It turned out to be a lot of chunks!
P.S. I think in the photo we ARE looking at an E10 (2002). Someone has just glued on a coupe blinker on an '02 fender (top edge still clamshells to the hood). It is very visually decieving though.
