There is a thread in the vanagon forum here by a guy doing a turbo aba. He mentions using a TDI outlet which looks similar. I think the engine and trans will still need to be slid back for clearance, but this piece at least is off the shelf so its cheap and replaceable on the road.

Yeah, I'm still going to have to shift the transmission back some I think, but I was anticipating that all along. This saves me from the big sweeping bend of the coolant hose though, so still a few inches.

I wonder if this flange combined with my Mexican bellhousing would keep my water line from contacting teh fuel tank?

I used an old Rabbit aluminum flange and cut the end of the coolant hose as short as possible to bring the turn as close as possible to the motor.

Even with the slightly shorter hose, and longer bellhousing, I had to cut away the fire wall in that area because it would have been in the way. It is still very tight.

But maybe with the flat flange it would work. Something to look at next time the engine needs to come out/down.

I'll try to remember to take some measurements when it gets here. It's scheduled to arrive next Tuesday.

I can't imagine changing that radiator hose is particularly pleasant with your setup. I'm trying to keep this thing as simple to perform maintenance on as possible, and use as few custom parts as possible, as I plan to drive this thing to the Grand Canyon one day.

I forget and didn't see obvious reference in the earlier posts .. are you using the crossflow ABA head or swapping to an earlier counterflow head?

Grand Canyon? Maybe we should plan a Watercooled Bay meet-and-greet gathering there next year or something .. springtime before it gets too hot or autumn after it cools down. Just 'cuz I have the spare HP for A/C doesn't mean I've got A/C .. yet. Twisted Evil

In my 72 with the 1.8 bottom end and 1.8 digi head I didn't have to modify the firewall at all. I simply blocked off the outlet on the back of the head. I'm pretty sure as well that with the 2.0 intake you will need to lower the motor - which I believe you have mentioned. The 1.8 head on the 2.0 bottom end is tried and true in the vanagon forum.

I'm keeping the ABA head because I wanted a stock configuration for tuning and parts chasing. Unfortunately, the ABA head doesn't have the option of the side water outlet like the 1.8 head does.

Tristessa, Grand Canyon won't happen next year, I'll be in RN school full time, but it's something I definitely want to happen when my daughter is old enough to appreciate, and young enough to where she still wants to hang out with us Laughing

And yes, I'm keeping all of the A/C related wiring and hardware for the future. On the open road, windows down is nice, but in traffic, especially in humid Florida, it gets pretty unbearable. I also have my daughter to think about in the back of the bus, but I've got an idea for a trick up my sleeve to help with that.

Why did you delete the factory cooler? Is it because its not effective being cooled by the coolant?

The factory oil cooler transfers heat from the engine oil to the coolant, and they're known to fail internally and put coolant into the oil and oil into the coolant .. which simulates the symptoms of a blown head gasket pretty well. They're not exactly a "cooler" in the traditional sense anyway, it's more to facilitate faster warm-ups than to keep oil temps under control.

Plus I already had a 48-plate cooler and a thermostatic Wahler sandiwch adapter on the shelf .. and I needed the nipple for my heater. Laughing

All conversions face this problem. We control the water temp but really don't want to know what's going on with the oil temp. I can assure you it's outpacing water temp no matter how well thought out we think the conversion is.

If you think about it we're sending the water elsewhere to cool it down but the oil just sits there baking. I changed mine every 1000 miles because of that. I hope to put a cooler set up together or buy the Vanistan stuff with my new deal.

I installed an oil cooler the same as tristessa. Used the same vovlo sandwich plate and installed the cooler itself under the bus at the opening for my rad. Lowered my oil temps from as high as 265 to 185. This has also had an indirect impact on the water temps. Overall things just run better and I am much happier with the lower temps.

We had a mini tech day at my shop today. 2 friends brought their bugs over and we took turns doing things to them. I was able to get some work done on the project too.

I got the rest of the cruise control stuff from the jetta, added that to the pile for future use.

I then took advantage of a BOGO promotion on Super Clean to de-gunk the engine and harness.

Tomorrow I'll start trimming the engine harness of the fat to get it ready for install into the bus. My A3 Bentley (hardcover Shocked

) will help with this. I plan to identify plugs I don't need (wipers, horn, front lighting, etc), I'll cut those plugs off. Once I have all of those cut off, I'll un-wrap the harness to remove the wiring that's not needed, then re-wrap it in fresh loom.

Don't forget to post pictures. You know we all like the photos. Best of luck with the harness. I found that to be the most tedious part of my install going through all the spaghetti.

Today's update: Wiring sucks.

This wiring harness is much harder to work through than the Ecotec. Some of it has to do with the "unique" way Germans do things in auto electronics (having a switch in the radiator to turn the fans on instead of letting the ECM do it for instance) but alot of the complication has to do with the available wiring diagrams in the Bentley. They are small, suffer from information overload, and are missing some things that Alldata provides with the GM's (like connector views for each component, along with wire info, making it easy to identify where you are at in the harness, and where the wires go).

Either way, I'm working through it, slowly but surely. I did pull all of the cooling fan wiring from the harness because I'm going to do it differently than VW does. I want to measure coolant temps at the engine, but turn the fan on in the front of the bus, so I'm going to use a generic fan turn on switch in my plumbing, then use that to trigger a relay up front for the fan. I'll also put a "manual" switch on the dash somewhere as an override in case the relay fails or some other unforeseen scenario.

It doesn't look like I'm going to make the labor day camping trip deadline I self imposed, but that's fine. My real deadline is the kick-off of show season in November, so trying to get done for September has put me ahead of my real deadline.

I'll also have more time to devote to the swap now. My schedule changed at work (for the MUCH better). I work 12 hour shifts now, so I have more days off, including a 3 day weekend every other weekend, and a minimum of 2 days in a row off (working overnight and only having 1 day off is a waste because I end up sleeping the whole time).
