Subaru 5 speed for rear engine VW now done

[ttriebler]

Hi all,

I have developed a crownwheel & pinion set for the Subaru transmission that allow the differential to be 'flipped'. This provides 5 forward gears & 1 reverse gear.

This can be used as a 4wd gearbox or a 2wd gearbox converted from the 4wd gearbox. Using a 2wd Subaru shifter end cone this gearbox will fit into type 1 beetles without cutting the torsion bar.

At this stage only a 41 tooth crownwheel and 11 tooth pinion are available.

I developed a pancake forging for these components and they are forged out of en36c steel, the preferred material for gears. CNC machined, ground and heat treated, they are o.e.m. quality and finish.





Price of a crownwheel and pinion set is $1500usd + shipping from Sydney, Australia. A locking kit to lock the gearbox driven shaft and pinion shaft for 2wd applications is around $100 usd.

I have some in stock now for anyone wishing to put an affordable, strong 5 spd together. Ideally looking for some workshops to order these in quantity and provide their own 5spd kits with mounts, output flanges and shift linkages. I am not able to provide full kits. Volume discounts are available.

Subaru 4wd 8 bolt gearboxes (99 on) that these were designed for will hold 206kw stock. That's around 275hp. If you upgrade the gears for an extra $4000usd or so they will take 500kw or approx 650 hp. Gears in both synchro, dog box, straight cut and normal are all readily available.

Please contact me for any further information at [email protected]
I have also put together a website that provides more detail:

will these gearbox allow a vw aircooled engine to be mated to them without an adapter flange.

[ttriebler]

Unlikely as an adaptor plate is neede to mate Subaru engine to VW gearbox.
The good news is that the distance from the rear (flywheel end) of the gearbox to the output shafts on the Subaru gearbox is less than on a VW box. Adding the adaptor plate would probably get the distance back to standard.

Hopefully some bright spark will be along shortly with some diagrams and measurements to help us out.

From my notes:
The VW swingaxle trans measures 7-5/16" from the bellhousing flange surface to axle centerline.

The Subaru FWD and 4WD 5-speed measures 6.5" from the bellhousing flange surface to axle centerline.

Here's a video of our test buggy happily going down the freeway. Subaru ej25 motor, entry level subie 5 speed with vw cable clutch and bowden tube. 3.9 final drive ratio and 31" tall tyres. This runs our Subaflange output flanges which allow the use of short beetle drive shafts and type 2 cv's. I'm also testing our bellhousing/adaptor plate which allows aircooled motors to bolt up to the subie 5 speed.

...... entry level subie 5 speed ........

What is the cost of one of these "entry level" 5 speeds setup for rear engine use?
