The future of Subaru ‘Twin-scroll’ Turbo engines is here!

After over 18 months of development we now have our new Twin entry turbos available for Sale.

Peter Marsh, Managing Director of Turbo Dyanmics talks about
the new Litchfield Subaru Twin Entry Turbo project

The official launch takes place at the 2009 Autosport show at the NEC. However we are now taking orders for our initial production run. Production of our unique exhaust housing has been completed with all casting currently being ceramic coated. This process is due to finish before the Christmas break with Turbos available to be built the first week in January.

We would like to thank the numerous customers that have been patiently following our testing and we can assure you all the wait has been worth it!

The details of the new Litchfield Turbo are:

• Straight bolt on turbo for all Twinscroll JDM STI models from 2003-2010MY
• Designed in the UK using the latest CAD and CFD techniques
• Cast and machined in the UK by OEM Turbo production company
• Exhaust housing made from the highest quality Ni-Resist iron (unlike most brands)
• Two internal volute sizes allowing for perfect matching of customers performance expectations
• Each housing has the acclaimed Zircotec Ceramic coating that drastically reduces the under bonnet temperatures and allows maximum turbo response.
• Designed to run the latest Garrett Ballistic ball bearing cores with their proven performance potential and superb spool up characteristics
• Custom cast compressor covers for both standard cable and Drive-By-Wire throttles
• Compressor covers available in over 74 different configurations with options like Ported Shrouds and larger 76mm intakes.
• Extensively tested on JDM 2.0litre and upgraded 2.5 Twinscroll models to provide popular power options but customised version are also available.

To simplify the ordering process we have produced and tested key turbo combinations. These combinations have easy to follow part numbers as shown below.

LM400 (HP rating) – S (Exhaust housing size S=small L=large) 60 (Compressor cover size)

Examples of popular Turbo combinations:

The LM400-S60 turbo is rated for around 400bhp with near standard spool up characteristics. This Turbo is designed to run on the 2.0litre STI engines and uses the smaller internal volute in order to maximize boost response. The turbo uses the 0.60 Compressor cover with the 58mm intake. This is the same spec of turbo we ran on our 2009 Type-20.

The LM450-S60 turbo is rate for around 450bhp with peak boost arriving 500-700rpm later than the LM400. This Turbo is also designed to run on the 2.0litre engine and uses the smaller internal volute in order to maximize boost response. The turbo uses the 0.60 Compressor cover with the 58mm intake.

The LM450-L60 is the 2.5litre version which produces 450bhp and uses the larger internal volute which does not become overwhelmed by the larger engines exhaust gas flow. This turbo uses the 0.60 and offers instant throttle response and no lag making a superb street turbo.

Below are the introductory prices for our turbos and the range of options we offer. We will also shortly add the conversion parts required to take a US or EU model Impreza STI to twinscroll.
