About

So, my mechanical experience is limited to working on an 1984 gas VW Rabbit when I was 16 in 1996. I bought that car for a $1! Too bad it was totaled by a mini-van running a red-light.

I'm an IT (UNIX/OpenSource) engineer by trade, but I have been working on my 1982 1.6na diesel Westy since 2012. So, I'm geeky, but new to being a mechanic to my van as much as I can. Some stuff though (brakes/suspension) still gives me the willies to have someone more experienced do it; I had a bad experience with a brake caliper bolt flying off in m 84' Rabbit that scared the shit out of me!

In this regard I hope to get a decent engine setup after learning it and then take it to get the conversion done.

The Process

This is where I'm going to linking to my youtube videos regarding my steps of building up a new-long block AHU engine using a used complete engine from Quality German Auto in Ontario, CA as a reference. Then the used engine someday will be either a backup/spare or for another project.

Here is the new long-block and used engine:

Preparation

I bought two engine stands identical in the process of mounting the new long-block and the used engine onto for my work.

I first had to remove the clutch from the used engine to allow clearance with my mounting hardware to the stand.

Heater Hoses & Engine Bracket Removal

The assembly is held together by some brackets and one nut head which can be seen below center photo between the two black hoses

Here is the video I made of the part I took off:

ECU / Wiring Harness

The side of the clutch top center there is a round cluster of wires and other plugs going into a central hub.

It looks like the below. I was able to disconnect everything but the glow-plug bar. I did the whole counter turn try and remove the plug, but no go. I just snipped the glow plug harness cable.

The rest I was able to unplug and the harness and all the wires came free:

EGR Removal

You don't need the EGR! From what I have been told in the TDI Conversion list was the following from Karl M. @ link Westy Ventures: "In many early TDIs, EGR contributes a lot to the clogging of the intake manifold and ports. Many have deleted or blocked EGR on TDIs to avoid the buildup of nasty gooey carbon. There also is no easy way to control it on an mTDI."

Service Manual Reference

  • Bentley 26-6 - EGR
  • Bentley 26-8 - 1Z / AHU specific
  • Bentley 26-9 - Fig 13.

The Details (my collected research before proceeding)

There's a decent article on TheSamba about what parts you'll need

http://www.thesamba.com/vw/forum/viewtopic.php?t=410813&highlight=ahu+intake

What isn't needed from stock AHU Engine

If going mTDI the following are not required:

  • electrical harness
  • MAF sensor
  • MAP sensor
  • IAT sensor
  • Injector #3 needle lift sensor
  • Fuel temp sensor (inside IP)
  • N75 & N18 valve

Air Filter

Donaldson filter G065433 install

Tranny Upgrade

The TDI won't have any difficulty cruising at 3500 or even a bit higher. The only downsides are noise and a bit of a drop in fuel economy. If your preference is to cruise at 65, then I would gear 3,000 @ 65MPH. With that gearing you will be able to cruise at 70-75 if need be and will still be high enough in the rpms @ 65 to develop enough HP for cruising with a 'cushion'.

Max torque on a stock TDI is around 2200 rpm. Max hp is around 3800 rpm. The TDI seems happiest in a Vanagon between 2600 and 2800 rpm. You are above the max torque, but well below the max hp. Your gearing and tires will dictate what speed that is. In this ratio, I would think a Westy would be more the range of 2700-2900rpm to account for the extra weight; ~700lbs last I heard!

If you don't have A/C or PS, you can use the VR6 water pump pulley (028-121-031-E) and use the serp belt to run the Alt and water pump.

Oil Pump

VW p/n # 068 115 105 BP

NOTE: This is included in a long-block. I wasn't aware (my own ignorance) that a long-block included this. So, this is more a reference point for others in a similar boat.

Parts to Obtain List

NOTE: some of these parts you can obtain from the used engine. However, as I want to use the used engine for another project someday, I rather replace what I need for it on the new long-block. Everything below takes a Long-block 1Z/AHU as the base up to an installable engine.

I don't include pricing since that's a fluxing item whereas a part description / number won't.

Transmission

I'm starting with an 82' diesel, so I *have* to upgrade my transmission or expect to blow shit up early on.

I'd love to go 5spd, but not knowing enough to go this route, I have decided on a rebuilt DK (80-82 air-cooled Vanagon transmission).

I would assume "most" going to a TDI would really want to regear their transmission or swap out their transmissions.

Decision

Since each setup is different for me I decided on the following:

AA Transaxle - Rebuilder

My rebuild included:

3rd 1.12
4th 0.75
LSD

For my tires my RPM ratios look like:

4.571 FD @ 0.75 - 2863 @ 65mph

4.571 FD @ 0.75 - 3083 @ 70mph
