The ideal interface between the Subaru engine and the Vanagon manual transmission. Made from an aluminum alloy casting, it is precision machined and is designed to use an integrated slave cylinder & release bearing. This housing bolts to your four speed or Syncro transmission and connects directly to any Subaru engine from 1990 onwards.
Also great for sand buggies using the Subaru engine and the 091 VW transmission.
The heavier flywheel allows driving at a lower rpm than with an adapter and the motor seems smoother below 2000 rpm. The transmission also seems quieter, possibly because of the smoother power delivery. The clutch is super smooth on both disengagement and when starting from a stop.
The advantages this bellhousing offers over an adapter & custom flywheel
- Much stronger engine to transaxle connection, plus 1999 and later engines use an additional 4 bolts.
- Better clutch options
- A reliable starter with more torque
- Super smooth clutch disengagement, no more stiff and glitchy pedal or $100 cross shaft
- No relocation or heat issues with the slave cylinder for turbo engined Vans
- Heavier flywheel for better low speed operation
- The starter is easier to access in a Syncro
- Big bonus for Syncro owners; the transmission can be removed and replaced much easier with the engine installed!
- If the flywheel ever needs replacing, the cost is $30-50 for used or $200 or so for new compared to over $350 for the custom adapter type flywheel
Parts included in the package

- Fits with any engine mount, any oil pan and all known exhaust headers.
- Our bellhousing is designed to position the Subaru engine in exactly the same place as the Waterboxer which is 15mm more forward than when using a 5/8" aluminum adapter and specialized flywheel.
What you will need
- Vanagon transaxle with 10 of the original bellhousing mounting bolts
- RTV or similar sealant for the bellhousing to transmission surfaces
- Original Subaru engine to transmission bolts
