200Tdi vs 300Tdi bellhousing bolt pattern?

The worn 300 is still plugging along in the fender at the moment (drinking oil)
The rebuild is going slowlllllly due to parts stuck in cairns and me with no desire to drive down and get em!

I guess the only issue with the 300 into a series without a turbo is having to make an exhaust manifold - not end of the world but hassle. A 300 with appropriate timing case components and well sorted head and gasket shouldnt pose any reliability issues compared with a 200. Why not go crazy and convert the timing case to chain drive splash lubricated from crank seal? Couldnt be too hard for someone of your engineering capabilities!

Don't the 2.5D (na) manifolds fit?

In the case of a 200/300Tdi into a series with series gearbox, I personally, would just turn down the boost a bit, instead of removing the turbo. If you turn the boost down to ~7psi or so an intercooler is practically useless, so you can remove all that, but still have some benefit from the turbo, at levels which hopefully won't kill the box.

A conversion to a timing chain would be tempting, but probably too much effort, unless I can make it a project for a final year mech eng student...

Final year project, then talk with the business school an get one of their final years to market it and voila - Aussie Made solution!

It surely would be cheaper than stinkin noisy gear sets that detonate.

What is it, Three sprockets of two different sizes, a double row chain, a chain guide bolted in the idler position and a tensioning guide to the tensioner bolts holes.

With the available 'slop' in the IP shaft bracketry, the cam and crank design you could almost make the chain correct length, slide all three units directly onto shafts and then you would just need chain guides and no tensioning?

Its obviously not that simple otherwise someone would have done it by now - but everytime I look inside a timing case double row chains go round and round inside my head!!!

Nice idea on deboosting the hairdryer and losing the IC.
