Porsche 997 C4 V8 Turbo
Discussion
To all Porsche 996 or 997 something different
Currently in the process of finishing our 997 C4 V8 Turbo 600bhp that will be going on the road as my daily car. We have done this project because it works so well and made sense from the cost to build and the performance.
Would this be a project you would be interested in finding out more about.

Hi, My name is Angus (Goose) originally PH name Argooes
I am not a business I am a private developer that enjoys building cars. This is not my first LS Conversion I have modified a number of cars using the LS1/LS3 power plant. My first project car was a TVR Griffith, which was done over seven years ago by a developer in stoke.
But have always wanted to do a Porsche over two years ago I started investigating the 997. Why, well it’s no secret that Porsche have had lots of problems with their engines. I was shock at the cost and the more research I did the more I wanted to do this project. As we are aware from discussions with the US this is the first 997 to have a LS conversion.
Project Car
Purchased 997 C4 2006 from Porsche specialist with a problem engine. Sold the engine to nice chaps at Hartech so nothing is wasted. We have used the existing gearbox with an adapter plate and the existing AWD system. We have continued to use all the existing instruments and Porsche engine management systems but have removed all the Porsche ancillaries. We lost so much weight from the removal of the Porsche engine and ancillaries that we had to fit smaller springs at the rear so that the car sat as before.
A standard LS3 with a good road/race cam can give around 520BHP with great torque and good economy. In addition to this we have added a turbo and we are looking for around 600bhp. Craig at Dyno Torque has carried out all the development work with testing and tuning at Emerald.
