Its a 520-530 hp max turbo with a max boost on an engine like this of approximately 1.6 bar. After that back pressure goes through the roof and turbo shaft speed passes the recommended limits. So if you were over these figures then there is a good chance this has contributed to some of the issues you are seeing.

Fantastic, thanks Clive. It looks like we are going to end up with the full spec engine and gearbox after all. Happy customer here.

We were running 1.6 bar, I know that much. The full frame kit should overcome these problems with an external and larger wastegate (I am advised). Plus the V-Band system looks so much more efficient and a better physical fit.

Clive tells me that the parts required for the Samsonas sequential box have arrived today. Really chuffed. It's going to be really good now.
