After hard accelerating, when I lift off the pedal there is an very rattley noise. Is this normal, as I have had cosworth turbo's etc and never experienced a noise quite like it.??

probably a broken wastegate hanger.

figured it was from that area, not too big a job if that is the case.

Bloody annoying though..nice whistle under acceleration..then lift off...rattle chatter rattle...bit rubbish sounding!

Will deal with the problem when I can get hold of some 8mm studs to replace the missing ones!

Some more thoughts on rattles including brackets, heatshields, wastegate spring, etc. -

getting the wastegate bracket replaced is HARD with the engine in

It could also be the timing belt cover (if installed) rattling against the pulleys when the engine shifts. BTDT

The guy who had the car before me said he'd recently fitted a new wastegate, so he may have left a few things loose I guess. After all, he didn't bother to replace the missing exhaust studs so maybe his workmanship was not up to scratch.
