Does anyone know where to get a pd150 hybrid turbo upgrade from??

Where are you? I would always recommend getting the supplier to fit it and remap for you, as then there are no issues later on with people saying the turbo was fitted wrongly or the rempa blew up the turbo etc.

Shark Performance are in Mansfield, Unit 18 are in Milton Keynes and, if you're brave, and fancy something different - Darkside Developments are in Barnsley.
