Thanks for the offer, I already purchased one.

He removed the tapped plug for the water temp sender to make the outlet: http://picasaweb.google.com/itzdshtz...47187197938770. He drilled and tapped some mounting holes then fabbed an elbow for the pipe connection here:
http://picasaweb.google.com/itzdshtz...46113456114738.
If you look at the rest of his blog you can see he has a machine shop that few have, but he's done a lot of custom work to the engine that will definitely improve the cooling. My question is: where does he connect the flow from the back of the head? It seems it would be better to run it right into the upper radiator so that after the system heats up and the thermostat opens (and the thermostat closes the port from the head) the flow would be forced into the radiator.
D24T motors already have a connection identical to that on the back of the head, it feeds the oil cooler circuit. Substituting the oil-to-water cooler sandwich plate for an oil-to-air cooler and plate (e.g. Volvo turbo gasser plate slides right on) and running a hose direct from that port to the oil cooler return above the t-stat might promote more consistent/accurate/rapid thermostat response by blowing hot coolant of that reflects cyl head temp on a stable basis right onto the t-stat wax pellet might help stabilize temp. Possible that was the idea this builder was working with, hard to tell, Vanagon owners with dual heaters living in cold climates often have to make provisions like these in cases where heater return coolant passes by the t-stat (as with this motor as well as the Subaru swaps) since the dual cores in cold weather are able to extract enough heat from the coolant that it causes overheating when the t-stat is "tricked" into closing on a hot engine.

Running it to the rad is not a bad idea either but wouldn't amount to much more than adding a second upper rad hose, which is already big enough, insufficient throughput in the rad hoses is not the problem here IMO, rather a potential for incorrect thermostat response to engine temp. My approach would probably be to move to a proper oil cooler and then block off that port, or use a small diameter hose to blow back on the t-stat. Hard to guess what this guy's aim was with the big connection back there if it wasn't one of those two possibilities, I would be interested to know more....

I did this same swap with my 5+5 years ago. It's a pretty straight forward job but, you may have problems with the passenger side tie rod hitting the vacuum pump.

Good Luck!

I would take it if i had a car to shoehorn it into. I suppose its a bit too long to fit in a mk2 VW?

Default 2.0 5 cylinder turbo diesel

I'm finally going to start my 2.0TD into a 1987 Quantum Syncro Wagon (QSW) project and will begin a new thread after getting started and taking some pictures this weekend.

I'm going to send GTiTDi a PM and see if he still has any spare parts leftover from this project.

If anyone else has some 2.0TD parts or even a spare engine let me know.

Right now I'm looking for an alternator bracket and alternator that fits the passenger side of the 2.0TD off an Audi 5000 or Audi 100. I need to move the alternator from the driver's side as currently situated in the QSW to make room for a bigger oil cooler and different larger radiator setup, possibly even an inter-cooler.

Hey, glad to see some 2.0 TD love. This is great! I've been down a similar road before: http://vwdiesel.net/forum/index.php/topic,25252.0.html, so let me know if I can help.
I hope to do another swap in the future, just haven't find the right candidate yet.
I've got quite a few spare parts, so shout out if you need anything. (Block, crank, cam, 155 bar injectors, injector lines, oil pump, etc.) Good luck!

Excellent thread on your build.
I read it about a month ago and will go through it again this evening.
You did a lot of custom work on your's that's very impressive.
Thanks to you I'm going to look for that 20V Turbo oil pan, there's a 20V Turbo Audi 200 in my local junkyard, excellent idea.
I also like the glow plug relay.
I've got the same intercooler but not sure how it's going to fit, the QSW is a lot tighter and I've got to put in the secondary radiator. One of my biggest concerns is getting enough cooling capacity.

I did my build thread on the D24T site here:
