I fought I would update this thread as lots has changed
The engine lasted 4 track days and dropped a valve, Supertech say its due to them being incorrectly fitted.
The damage
It compleatly scrapped the engine, so we had a new engine built but this time we added a strocker kit to take it to 2l and uprated everything.
Added a TSR tubular exhaust manifold and a GTX 2867 turbo and external wastegate
The result was we had to limit the power to 400bhp as anything over that just spun the wheels!! (No lsd)
We did around 20 trackdays I with the car over the summer
