Bremar Automotion has developed the necessary components required to convert a 5 speed manual AWD Subaru gearbox to a 2WD transaxle suitable for use in mid mount engine applications. If you’re looking to do this conversion, then you’ve come to the right place…
A splined locking spool replaces the centre diff and sends all drive torque to the gearbox’s front diff. A machined billet aluminium blanking plate replaces the rear section of the gearbox and really looks the part for exposed boxes. All kits come with a full set of installation instructions.
We also now offer a 3D model of a Subaru EJ20 engine complete with 5 speed transmission. The file is suitable for viewing in CAD software or for 3D printing.
For more information, see below for frequently asked questions.
All pricing is in Australian dollars, including shipping to any location worldwide.
Q: What gearbox will the kit fit?
A: Any 5 speed manual Subaru gearbox. It won’t fit 6 speed or auto boxes. Our customers have fitted the kit to WRX, Liberty GT, and Forrestor GT gearboxes from late 90′s to mid 00 models. If you find a box it doesn’t fit, we’ll give you a full refund.
Q: Which gearbox should i use?
A: The simple answer is the later, the better. Later model boxes will generally have less km on them, and from around 2004 there were changes to the casings to reduce flex and keep better alignment of shafts and gears. Look around the net and there’s plenty of specialist Subaru websites and forums out there that can provide you with more info.
Q: How much power will the kit handle?
A: We know of race cars running our kit with 240kW at the wheels with no problems.
Q: Will the gearbox be strong enough?
A: It really depends on your application, and ultimately, how you treat your box. Generally, cars running this kit will be much lighter than the Subaru that the box has come from so the box will be less stressed than the stardard application. Also, now being 2WD, the tyres are more likely to break traction than in AWD form, where the car maintains grip and loads the gearbox up. And in the unlikely event that you do need a stronger box, there’s plenty of billet gearsets available for the 5 speeds that are near bullet proof.
Q: Do you sell a shifter linkage for a midmount powertrain?
A: No, due to the varied number of installations, it’s pretty much impossible to develop a generic shifter solution to suit all applications.
Q: How does order, payment and shipping work?
A: Place your order using the ’Buy Now’ buttons. Your payment will then be processed through PayPal secure payment gateway. Make sure your details are correct as we will ship to the shipping address provide through PayPal. Once we’ve received your payment, your order will be shipped via registered airmail, and you should have your parts within 10 working days.
Q: What file format is the provided 3D model?
A: We provide the model as an STL file. This is ideal for importing into CAD software, checking clearances, 3D printing and most 3D viewers. It is NOT a ‘true NURBS surface’ as a modelled CAD component is and hence cannot be used to machine components from or create 2D drawings. Additionally, we only provide the exterior surface of the engine and transmission, there are no internal features to the model.
