I have an 03 Cobra Mustang with supercharger and twin Hellion turbo 61mm kit installed. I recently blew my engine and had it rebuiltit. The shop is charging me 5000. To take out and install the engine along with the turbo kit. Is that a good price?Also what is a the average price for taking out and reinstalling it along with the turbos. I know the kit is a plug and play.
