Totally agree with the complexity, time and money needed to supercharge a standard Crossfire. Only reason I am even idly considering it is that I want a SRT motor with a six speed. Don't want no damn automatic. Seems my choices are to add a six speed to a SRT, or put the blown motor in a standard Crossfire. I am leaning toward the latter primarily in that I have one in hand. Had a BOLO for a long while at several yards for a wrecked SRT, but these are obviously rare. Did get one hit, but they wanted 7.5K for a rolled SRT.

I think that if the boost is kept low, a standard motor should hang together if you drive it within reason - ie, no drag race starts etc. With good fuel and ignition management, this would be doable. Unknown is how to do this - looking at an MS3 in a piggy back role to just take care of the engine management and leave stock ecu to take care of whatever else it feels like doing.

My son runs an auto repair shop, so we have the tools, room etc. - biggest factor in not starting is a) money and b) fear of screwing up a perfectly good Crossfire.

It would seem another, maybe more reasonable alternative, would be to swap in one of the newer DOHC 3.5 Mercedes V6 engines. Anyone know if the block to bell housing pattern is the same as on our 3.2 V6? Those engines are rated about 300+ HP, so would have close to the same power without the complexity of adding forced induction. I know some folks have swapped in the high end AMG V8's, but I am talking about a presumably lower cost approach to getting a bit more oomph.

As had been said, all it takes is money.
