John Conchie Turbobus
Hi there!

I recently bought this interesting book.

Found the article about Turbobus interesting so I decided to do more research.

Unfortunately,I didn't go very far,not a lot is to be found on the internet.
John Conchie died last year Sad

I wrote to Alpine Developments in SA if they can hook me up with some pictures.The guy was very nice,and we exhanged many emails,unfortunately,he couldn't find any archive.He really looked hard for me,and keeps my email in case in found something one day.

Here are some pics of the article,I'll try to scan them at work when I have time.

Re: John Conchie Turbobus
MY first syncro had one of these but fitted to a 2.1 not a 1.9 as this was, went really well until it threw a rod, Alpine has not done this conversion for at least 15 years, the wasserboxer was not really up tho the extra performance. rather fit a 2.5 suby turbo, it was at least designed to have the turbo.

here are some details from Brickyard in the Uk on the 1.9 turbo
Alpine/superwagen Turbo-bus.

The European Transporters only came with relatively small engines and in South Africa you can be at shore line one day and up in the mountains the next, with power draining altitude and a full load your in the sh*t! VW in Germany didn't want to install a bigger engine due to taxation expense for the owners which would put them of buying a new Transporter . The South African firm Alpine saw a gap in the market for a more powerful Transporter and developed the alpine/superwagen Turbobus to meet customer need for a more powerful van.
The conversion was carried out at one of the 104 superwagen engine building dealers through out the country. When the 1.9l water-cooled engine came along John Conchie took it upon himself to start work!!
the conversion involved a 8 hour transformation in one of the Superwagen workshops and each engine was tested on a dyno test bed to make sure it performed!
the spec of the engine is as follows.

Low compression Cosworth pistons (7.2:1)
Garret PB-03 turbo
Hand made exhaust manifold.
Inlet manifold modified to suit a twin choke Dellorto blow through 32mm carb.
Modified Oil pump.
High pressure roller cell fuel pump to cope with extra load.
Oil cooler..
Sadly I have no descent photos of the conversion (not worth scanning anyway) but the turbo was mounted just below the crank pulley, lots of pipes but no mods were needed to the engine bay and load bed was kept at the standard height.
Max speed - 96 mph
peak power - 105 kW (your guess is as good as mine.)

I may be a mechanic, but i can't fix stupid
