As of right now we are orienting the kit toward the 2.5L (non S) models as they are the cheapest to source and are starting to become more and more common with damaged engines. Even without damage the OEM engine is less reliable than other engines, requiring expensive parts and aftermarket attention just to make them reasonably reliable.

As has been seen online, a few V8 engines have been put in this car with varied degrees of success. The kit we are building uses an Audi 4.2L all aluminum V8 from the same period as the vehicle.

This engine will have a CNC machined custom oil pan designed for drysump with integrated bosses for a mount functionally similar to the OEM Boxster engine mount. We are still figuring out the details for the kit as we produce it, but at this point we wanted to get some feedback from Boxster owners as to whether or not anyone would be interested in this package.

The package will include everything it will require to install the engine in the vehicle with no fabrication or modification required to the OEM vehicle. In this respect, the entire swap can be reversed if desired. The engine will produce around 350HP as a target for the first kit, depending on testing with the 5 speed transmission's strength. The engine kit will have a standalone ECU with programming and wiring designed to interface with the OEM VME so that gauges and all vehicle systems will operate as normal. A/C will be retained, as will power steering, with suitable lines and fittings as required.

From our initial calculations, this configuration should weigh very close to the same weight as the OEM engine.

The Audi 4.2L Engine was selected due to it's light weight, short overall length, matching transmission housing bolt pattern and low cost. By replacing the large cast intake of the Audi engine with independent throttle body assemblies, we hope to lower the weight of the engine further and improve throttle response as well as maximum engine output. The dry sump system will also improve engine output and make the package more suitable for serious track use.

We will be posting photos of the test vehicle as we progress. Any feedback is always welcome!
