The Crossfire is based off of the SLK Mercedes line. Only options were a 4 cyl, 4cyl supercharged, 6cyl (what we have) and the AMG Supercharged 6. That is all that will fit into the crossfire.

However, the PT shares the same line as the Neon. Which is why the PT and SRT 4 Neon can share the 2.4 turbo motor. Sure it is fast, but it is FWD. Currently they do not have any RWD cars using that 2.4 turbo motor.

Could you turbo the Crossfire? Sure. Build up the stock internals of the motor, forged pistons, better rods, lower compression, better head gasket, fabricate a custom exhaust mainfold to mate to the turbo of your choice. You'll need 2, as you are running V6 and not inline. Upgrade fuel system, exhaust, develop some kind of intercooler design, fuel management, etc.

You can turbo anything, it just takes $$$$, Time, and effort.

Turbo's are a lot of fun with temps under 85 degrees. Especially those nice 40 degree days 8) Anything hotter it feels like a 4cyl =/
