Porsche upgrades

With decades of air- and water-cooled Porsche engine experience we’ll work closely with you to achieve your upgrade or re-conditioning brief. We offer a range of Porsche performance upgrades and modifications such as a twin spark conversion, MFI injector conversion, shuffle pinning, Intermediate shaft bearing upgrade to the latest Porsche specification, oil bypass conversion and an oil squirter conversion.

Our specialist technicians endeavour to refurbish any Porsche engine components but in some cases erosion/damage of the casting can result in the need for additional services such as laser welding, timesert or helicoil of damaged threads and component straightening. At Fiennes Performance, our team have the experience to provide all of these Porsche engine rebuild services in-house.
