Hi Fozy it could be loads of things, as the boost has been turned up, and the small turbo works hard evern on a standard car it could be the seal on the shaft, take hoze off the front of turbo and see if you can move the end of shaft from side to side. Also it could be valve steam seals or worse it could be a piston ring like what happened to my car also with the same SHIT convershion from GGR !! mine started smokeing on the way home from GGR and they didnt want to evern look at the car when i phoned them !! I had one of there 305 engine killers.

Hope brett and shaz are ok and tell them to come all to the pub
