18. If you are really ready for some insanity under the hood, then give the guys at Turnkey a call. They have these engine available with packages including twin turbos and superchargers, not to mention custom cams and trick head work. If your checkbook can handle it, then power numbers between 330 and 775 hp are within reach. All engines are tested before they leave and can be rear-wheel-chassis dyno-tested once you have the engine installed if you want to bring your ride to the Oceanside, California, facility.
