The idea of this project is almost as old as the bus resto project itself – in fact they were born together. So in 2009 I started to look for alternatives – I was pretty sure of one thing: I want a Type 4 engine in my bus. Through my research I have always looped back to one single manufacturer Raby’s Aircooled Technology (Specializing in fully developed Aircooled Engines for all vintage Porsche and Volkswagen vehicles based on the robust Type 4 platform) and spent hours at night when the family was asleep learning about their services, what and how they offer – I was particularly interested in their engine kits as at that time (now they don’t do it either) they were the only ones to offer a kit that could be assembled by someone who have never even seen an engine out of a car.

But because the resto of the bus was full-on I simply couldn’t afford such an investment. And unfortunately by the time I wanted to make the move to purchase a kit – their program became obsolete and they were only selling turnkey applications. So I completely dismissed the idea if having a Raby engine however I still had plans to at least get hold of a DTM upright cooling kit for my old type 4 engine. Slowly everything faded out and turned my attention to other upgrades like the Subaru conversions done by Fellows Speed Shop

I had plenty of time to think and figure out the best solution as based and relocated to Dubai I don’t have my bus with me here. So I was preparing to “Subaru” my bus when the miracle happened: a Raby 2270-165 complete kit popped out from nowhere, exactly the same specification I configured in my head and believe it or not it was tuned a synhronised to be applied to volkswagen splitscreen transporter like mine.

There was no hesitation I went for it, here are the details:

The DTM shroud includes aluminium backing plate, aluminium surrounding ‘tinware’, crank pulley, fan belt, etc.. but excludes fan and alternator (standard Type 1 parts).
