This may help ya , There is few that have put SRT6 motors in a NA , I know of one I think in Texas , but Every thing must come with that to make that work wiring etc. , you would need to find a Donor SRT and convert everthing over There is few out there with the V8 's I think the E65 motors in them that fit , but the cost is about 25,000 to do ! yes it is that much , unless your like a few here that that love having something different and have the time and money , then this may be your options , The search button can be your friend in finding out about the builds that some have done , , for me I spent the money on a different sport car few years ago ,one where the after market is little more friendly to the HP I was looking for and yes I still have my Crossfire ,
