We have been developing the 2.0L TFSi cylinder head with porting specialist JP with some great results. The head was built with Supertech valves to an engine with low comp pistons and uprated rods with a BDM K04 turbo. Results have found (even with low comp pistons) a drop in turbo lag with full boost being reached sooner, smoother and harder than a standard engine. I dont currently have any RR results as the engine was build and fitted into a KTM X-Bow and they dont dyno well.
Some nice pics of the head:







Prices are £750 for the porting inc skimming, new high temp valve stem seals and guides (if needed)
