Turbo systems have been our passion for many years!!!
Our quest to constantly test, improve, and refine our kits has led to us to being able to offer the ultimate in quality, performance & reliability.

We constantly review our kits and testing new turbo chargers to ensure that you are getting the best, most efficient systems available.

The new Owen Development GBT Turbo Systems are designed to be a direct fit to Evo 4-9 with no other modifications needed. Based around the highly acclaimed Owens GBT ball bearing turbochargers. Designed and built in the UK these offer the best performance of all turbos that we have ever tested.
GBT offers the ultimate in spool, top end power, together with uncompromised reliability record making GBT the number one choice.

These turbo systems use of the v-band system allows leak free & convenient gasket-less seals between all mating surfaces.
