Product Description

Please call for Availability with time sensitive orders, systems can become back order from the manufature.


This turbo will be capable of supporting 800+ rwhp and great for the larger cubic inch engines to keep back pressure under control.  Most of these turbos listed are 65mm or smaller exhaust wheels which is a MAJOR limiting factor.  Our new 76mm exhaust wheel is going to allow for higher hp number with the larger 78mm wheel and keep the back pressure in check as well as keep from over-spinning the turbocharger.  You cannot beat the price and is a great upgrade if your already maxing out our ever popular On 3 76mm turbocharger with the smaller 65mm exhaust wheel.
