Launch of the MDX555 turbocharger range for Subaru Impreza's


MDX555 - 400 / 450 / 500

Launch of the MDX555 turbocharger range

 

Turbo Dynamics is proud to announce that the acclaimed MD555 has been superseded and has now been launched in three different specs, providing a lighter, stronger, greater flowing turbo to suit a variety of customers needs.

The exciting upgrade to the original MD555 centres on the introduction of the new TD billet compressor wheels. The MDX555 is a bolt-on upgrade for the single scroll Subaru Imprezas, and is supplied with a full fitting kit. It comes in three part numbers: MDX555–400, MDX555-450 and MDX555–500. The bigger the number, the bigger the compressor wheel and the greater the horse power. So its up to you how hard you want to boost!

The MDX555 is now available via selected TD Partners and Customers. This upgraded product offers more variation to the user and will prove more popular than its’ predecessor, despite the fact that the MD555’s popularity has never waned. Find out the MDX555 features below and if you have any questions or queries regarding this high performance hybrid turbocharger please email info@hybridturbos.com or call us on 01202 487497

Compressor Wheel

The turbocharger uses Turbo Dynamics own design billet compressor wheel which not only offers improved response but also improved reliability over the original cast compressor wheels. The size of the wheel has been designed and tested in our own CAD facility to deliver great performance, reliability and aesthetics.
Wheel sizes range from 67mm to 82mm depending upon flow requirements.

Compressor Cover 

In order to cater for the latest Subarus featuring fly-by-wire throttle control we have designed and manufactured our own compressor cover for these turbos. Offering different a/r options (0.60 or 0.70) as well as different inlets options (standard Subaru 58mm or 3” ported shroud) whilst also catering for fly-by-wire and cable throttle cars you can be sure we have a compressor cover option available to suit your vehicle.
Designed, cast and machined in the UK to our own exacting standard the Turbo Dynamics compressor cover allows the MDX555 range to be easily fitted to all Imprezas.

Turbine Housing

The MDX555 series of turbos feature our own UK designed and manufactured bespoke turbine housing. Based around the original OE IHI turbine housing and then refined using our in-house CAD facilities to optimise performance and to allow the fitment of a range of Garrett Ball Bearing Core Assemblies. The housings are cast from OE materials ensuring reliability.Turbine Housing

Zircotec ceramic coating in performance white is optional on these housings and other colours from their range can be catered for to suit individual requirements.

Core Assembly

The MDX555 range of turbos have been designed from the outset to accept the Garrett Ball Bearing Core Assembly which offers good response and reliability. Various sizes of turbine wheel are used to tailor the turbo to the performance requirements to ensure optimal response and power.
Bronze bearing carriers can be specified as an option on the MDX555 range which replaces the standard phenolic resin itmes. This is a good upgrade for anyone using the vehicle on track days or in a motorsport environment.

Actuator

Here at Turbo Dynamics we produce our own range of uprated actuators for a variety of different applications and fitments. A heavy duty, 1.2 bar actuator is usually fitted to the MDX555 range of turbos. Other pressures are available and can be fitted depending upon your boost control requirements.
