engine is back together now ,have got a new mount made to suit (steel) able to use standard mount now not one that has the wing(support) cut off and the pins ground away for the waste gate mount/engine mount. All of the braided lines that where added in the turbo upgrade have been changed to steel lines ,they got to hot and became weak!

10.8k rpm Would sound amazing, are you still using genesis rotors or did you change to a low compression rotor?

I put in racingbeat rotors, they are the lighten and balanced ones for boosted rx8, not cheap!!! they are good for 11300rpm.

Nice upgrades. With 14psi you should have around 260kw at the wheels?

I had an issue where I was running lean which destroyed 2 cats. But that was a mix of lean running for long times under harsh conditions and cheap cats not intended for the purpose.

What cat are you using?
