RE: Whats your preference
It's almost a no brainer. When you supercharge an engine that isn't designed for it there's a lot of things can happen and most of them are bad. So much has to change, from lubrication to heat to compression. From a reliability standpoint either get yourself a good cai, exhaust and predator tune or just buy the SRT. I think you'll be much happier in the long run. Just MHO.
