Yes, that is right. I have a na crossfire with just two extra cylinders, so if this works on my car it would work on any na Crossfire. The key for me and any 3.2 car is swawping in a 32 Kopressor ECU for a 3.2 and a 55 kompressor ECU for me. Rudy can adapt the ECU to your car. Both the na 3.2 and my 500 engine are 10:1 Selecting the right turbo is key. I am looking at a 67mm turbo with a T4 hot side with a .68 AR. With the right sized turbo, lag should not be an issue, plus from a dead stop you will still have your present power. A unboosted low compression SRT engine will be much more sluggish without boost and turbo lag would be more of an issue. If you know the parts to buy you can put together a higher quality kit for less than the cost of the STS set up. An advantage of the rear mount is it easier to do, and with jsut a small air to air intercooler can produce about ambient intake temps. Even if i have some lag, it won't be much of an issue since I already have so much low end torque with the V8.
