It's been suggested that I share my Boxster here by one of the Region 9 guys. This is also my first post on the PCGB forum so hopefully it's not considered too blasphemous.
This is my 1999 2.5L Boxster:
This is the engine:
And this is the turbo:
The engine is a VAG 06A 20V built with bits generally considered good for north of 600bhp. The turbo is a GT3076R on a log type manifold to try and get the boost threshold down as low as possible. It operates and drives like a standard road car as it has DBW throttle, dual sensor knock control, wide band lambda etc. etc. The engine emits to the same standards as the original and has a single, large metalic catalyst in the rear wheel arch, as the vehicle is pre March 2001 the catalyst doesn't need to be homologated to remain road legal. Closed loop crank case breathing and tank EVAP are implemented and properly controlled and the emissions performance is actually slightly better than the M96 engine as the 06A runs in L1 for much more of the normal drive cycle.
I'm quite often at the R9 monthly meets in this or my 996 so if you see it and would like a closer look then do feel free to ask.
