Owen Developments unveils the ultimate bolt-on turbochargers for 2.0 and 2.5-litre Subaru Imprezas
Owen Developments, Europe’s leading high performance turbocharger specialist and control turbo supplier to the BTCC & FIA Formula 2 series, is pleased to launch a range of four bespoke high performance 400bhp capable bolt-on turbochargers for the ever popular and tuneable Subaru Impreza in both 2.0 and 2.5-litre engine versions.
Built around a brand new genuine MHI TD05 core and turbine housing, these units are radically re-engineered by Owen Development’s technicians using precision CNC machinery to a very high specification, with the goal of radically increasing both the turbocharger’s gasflow and response. The units retain an ease of fitment not normally associated with this type of performance upgrade and also come supplied with a full fitting kit.
A key part of Owen’s enhancement process is the fitment of either a 68mm or 71mm billet HTA compressor wheel (depending on engine specification) that combines advanced aerodynamics with a precision CNC machined Owen Developments compressor cover.
Carrying range part numbers MHI TD0571HTA and MHI TD0568HTA, the Owen Developments Subaru Impreza turbos include the following key technical features:-
- Larger 68mm or 71mm diameter billet aluminium HTA compressor wheel
- Owen Developments CNC machined compressor cover to suit
- Choice of uprated 360 degree thrust bearings or the ultimate low friction ball bearing centre cartridge option
- Standard air intake to turbo inlet hose size retained
- Wastegate actuator installed set at 1 Bar
- 350-430 bhp potential with corresponding suitable modifications
The versions of the MHI TD0568HTA and MHI TD0571HTA Owen Developments Subaru turbos have been designed to suit the differing requirements of the EJ20 and EJ25 Subaru Impreza boxer engines, covered by the following part numbers:
OD-SUB-2.5-TD05-68HTA-JB-WC-7 (68mm compressor wheel with angled outlet to suit EJ25 Subaru Impreza engine fitments)
OD-SUB-2.5-TD05-71HTA-JB-WC-7 (71mm compressor wheel with angled outlet to suit EJ25 Subaru Impreza engine fitments)
OD-SUB-TD05-68-HTA-JB-WC-7 (68mm compressor wheel with straight outlet to suit EJ20 Subaru Impreza engine fitments)
OD-SUB-TD05-71-HTA-JB-WC-7 (71mm compressor wheel with straight outlet to suit EJ20 Subaru Impreza engine fitments)
