Srt6 has an air to water intercooler under the supercharger. The motor is all forged hand built by one person at AMG. Very nice high quality motor that is for sure. I hope this all comes together for you because this is something that needs to be done for us base model crossfires. Best of luck and I'll be watching for updates. If this does work out I'll be one that is interested in doing the same. Automatic just doesn't do it for me, I need my 6 speed!
