245 td

And now for something completely different...

Turbo drain line....

'82 245 TD. Has a very nice custom turbo installation that was done around here over 20 years ago, put on a stock D24 with no oil cooler and no boost enrichment. We picked it out of a field a few weeks ago where it had been sitting for several years with broken timing belt carnage, engine half taken apart and all crusty, and animals living under the hood (nice mouse nest under the cam, lifters smashed cockeyed etc). Now getting ready to install a proper D24T but need to figure out whether to try to use this manifold arrangement or to go with something else. It looks like this arrangement will flow much better than the stock D24T manifold but the turbo is ancient and unique... our local turbo shop had never dealt with anything like it and couldn't give us any info. Hard to know if the sizing, spool-up etc will be correct. Thinking if this doesn't work out we will be installing a VNT. Looking into options... it would be nice to find something that would be fairly easy to adapt to the existing flanges and plumbing. It is an old Rajay unit with 3-stud flanges on the manifold and downpipe side both, not sure if they are standard or shared with anything else but hoping they might be compatible with some other options.

Thoughts/ideas?

I wouldn't run the Rajay, they sold kits for vw's back in the day, and their turbos weren't usually the correct size/trim etc.. I would just run a straight T-3 if your not trying to make big power. the manifold looks decent, but longer tubing means more heat lost. You also need bracing since the turbo is hanging off quite a bit of pipe. Why not just run the regular T manifolt. You cant beat the 3 piece stock design. Hell they sell 3 piece manifolds for Cummins engines as a performance upgrade!

Looks like a pretty nice wagon though.

I bet that was a Boeing engineer that fabbed that turbo setup!

While it seems a tad unorthodox, I think that turbo manifold setup is pretty neat! For the sake of interest, you've got to get that engine running again utilizing as much of the original hardware as possible -- just to see how she ran!

IDP sway bar and a thermocouple, this guy was one of us!

That is pretty cool!

I wonder how many people have done the TurboDiesel 240?

each one has a certain twist it seems. None are the same.

It is going to get a Garrett GT2056V VNT turbo off a Jeep Liberty CRD, using a double-acting VNT actuator off a Dodge Shelby CSX to regulate it. This will be one of the first applications of a VNT to a D24T in the world.... stay tuned, we will report on how it turns out.

Looks like a fun project. I still have my D24T on a engine stand waiting to go in the 244.

As for the heat loss there is a gas burner system that puts the turbo on the tail pipe. you can look here. http://www.ststurbo.com/ Might be worth a study. I may try a setup like this with a T3 using my stock manifold, but Im a ways off from having a running engine. Currently agonizing over new a new oil pump or not. Big bucks. These engines are not cheap like their VW 4 banger cousins.

I'm familiar with the rear mount turbo setups. To get it to work worth a damn you have to wrap all the exhaust, and tuning (at least on gas engines) with those setups is difficult. They still don't perform as well as a turbo mounted on the engine. With a factory manifold easily available thats better in many regards, I was just thinking that would be easier/better overall.

I have a stock D24T exhaust manifold from a 760 but from what I have read there are clearence issues for a 240. Might be able to mill it. Im not that far into my build. I dont want to jack with the mounts or hack the cross member, as some have done. I want a car that is as close to the original design as possible. I just want power. The D24 is a dog. My VW Caddy with the turbo version of the 4 banger verses the original Na motor is night and day, but could be maintained by any diesel nut like myself. A hacked up car is just that. On the other hand I do like your T-5 swap though.
