The biggest cost question is the tuning ability. We work with Diablo, but I know the Crossfire market is way to small to even get a word in. I have several methods of tuning my sleeve, from around $550 to about $1,100. Overall costs will depend on which one will work the best when I put boost to the N/A engine. I know I will be mapping it to run a MAP sensor and ditch the mass airflow sensor, much easier and no recirculation concerns.

I would avoid a V8 if possible, hate to screw up the cars balance. I built quite a few Chevy Vegas with a small block 350 in them, so I know what you are talking about regarding power!
