UPDATE: As of JANUARY 13, 2024, I have turned over all sales and production rights of the starter adaptors to T3 Technique in Washington. This change is being made so that I may fully 'retire' and focus on my dream of world travel and no longer be tied to shipping.
T3 Technique is a growing business and I am sure you will be in good hands with his support of this product and his many more offerings that support the T3 / Vanagon world! Many thanks to the thousands who supported my development and distribution of this product! 

I will also be listing items on this page for sale as I gradually go through the many boxes of NOS and used Vanagon and Syncro parts in the near future. Thanks!

"MORE-TORQUE" starter adaptor for engine conversions: Many folks have been using the 'Hi-Torque' IMI starter. These have been known to fail frequently and do not have enough speed OR torque to start most high-compression engines, especially the diesels and some Subarus. Even the 'new improved' versions offered are no better. I developed this adaptor to utilize the commonly available, powerful (1.8~2.0 kw) and reliable starter from the 1996 - 2003 manual-trans VW TDI (diesel) cars, the SR0408X/409X. The adaptor mates with this starter to provide an easy installation to the waterboxer manual-trans bell housing. The SR0408X/409X is a Bosch high torque gear-reduction type starter, is slightly longer than the stock wbx starter, and has a self-supporting shaft-- it no longer requires the pilot bushing to position the shaft end. On Syncro applications with locker, a 3/4" notch will be required in the diff-lock bracket, and you must use the longer (2.25") type bracket (photo below) and corresponding locker pin. Note that the SR0425X / SR0425N starter will work without clearance issues in a Syncro w/locker, as long as you aren't starting a diesel. The adaptor will work with ALL conversions using a Kennedy, Eurospec, SmallCar, Vanaru, or Tiico engine adaptor plate and stock-diameter ring gear + WBX bell housing (NOT diesel bell housing!), also with the stock Vanagon WBX. The 'automatic' version adaptor is essentially a thicker version of the manual adaptor - and has been shown to be a good fit for the earlier Bus or Beetle manual transmission (70's) so we've got you covered there as well.
Note: 'VALEO' brand starters have fitment issues and are not compatible with these adaptors. Only OE Bosch or Latrical / California Starter brands are recommended.

Some Valeo starters may end up appearing as Bosch 'rebuilt' also, confusing things further. The Valeo units can be identified by an 11-tooth gear and external bolts that hold the starter together. AGAIN: these DO NOT FIT!

Manual and Syncro version "MORE-TORQUE" starter adaptor: New, improved version! My new machinist has improved the design and appearance, I think you'll be impressed. These fit all conversions using the Vanagon manual - transmission bell housing and 75-on bus.    

 AUTOMATIC version "MORE-TORQUE" starter adaptor: This version fits all Vanagon automatic transmissions and also fits well on the older pre-091 transmissions like the Beetle and early Bus. These VWs used a longer starter drive so the spacing works perfectly.
 

OEM-style plug for the TDI starter. This ensures a solid connection and seals against dirt and moisture.
