I know when he bought it the car was apparently a fully built engine, but as it turns out it was done badly, i know he's currently rebuilding at the moment, but not 100% sure whats gone into it. i know he had put a hybrid turbo on it, and then he had engine issues (not the turbo's fault) turns out i think the engine had been over bored, and sleeves were to big, but its now all been corrected and refitted. i don;t know what is and is no longer forged. i know he was looking at boost control setups and looking at being able to turn it all down low etc (in effect allowing him to drive a bog standard 2 litre) and then when he wanted to play, be able to turn it all up again.
last time we had a play i know that it was just keeping up with my car but as mine got to 100 it would start to pull ahead before we ran out of tarmac on the airfield we were on. and my xkr is currently near 440 bhp. but thats the difference between a turbo'd 2 litre and a supercharged V8.
