      Found a great deal on an full parts 1998 jetta ahu tdi a few weeks back and got in contact with the seller immediately. That being said i met up with him and got things all settled. From the information he gave me the car had an veggie oil conversion kit on it for most of the engines life. It was considered total due to an accident he had which consisted of the car being flipped onto its side. The engine was luckily not hit in the accident. It kicks over quick and runs very smooth. 215k on the engine. trans and clutch in great shape Johnstamos will be helping me with this swap since this will be my first and he could chime in if anyone has questions about the swap.



      not the cleanest but who cares when its an tdi. do have engine cover for it though



      the car it is going in...
      later 2.0l




      The goal is to have it completed by h2o but if all things go to plan it will be done weeks prior to that. Pretty much keeping it stock for now with a mild tune.

      looks like a fun swap! im in to check out the progress..
      seems fairly straightforward

      I have never seen anything that makes as big of a mess as running Veggie Oil. There is literally a 5mil think film on EVERYTHING.

      That said, its a 99% complete swap car, that runs GREAT, and the previous owner took good care of her, so it should be about as straight forward a swap as they get.

      TDI swaps are basically the same as VR6 swaps +tank, lines, pedal, more wiring, rewiring the tank sending unit, HVAC(some models) and I can do Vr swaps in a single day, so aside from all the side tasks, will be a quick deal.

      Car is being done in my free time (when his schedule permits as well), away from my garage, in his small one car attached, so won't move as fast as it could, but will be done as fast as I can push him.

      Phase one: Deadline of August 17th to get all done. So realistically, 15~ work hours.

      Get running. (Done)
      Drop full drivetrain w/ subframe.
      Drop tank and lines.
      Remove dash, and get the TDI specific parts, ignition harness, HVAC box, cluster harness, throttle pedal/potentiometer, ect ect.
      Strip car and send her off.
      Access engine/trans condition.
      Strip and clean, and clean, and clean, engine/trans.
      Clean soot from intake manifold that is probably plugged 75% at this point as it has never been done.
      Reassemble with 95% new parts as budget permits. (Hoses, belts, Vr6 pressure plate/TDIdisc, cts, all external gaskets/seals, glowplug harness, ect ect.
      Clean up harness. EVERYTHING on the car from the factory minus maybe cruise will be staying, so very little harness work needs done.
      Flush ENTIRE fuel system, as it is caked with Veggie Oil buildup.

      As time/budget/what I can convince him of() permits, most of the fab supplies I have already laying around the shop, so it's almost all time.

      Build a 2.5" downpipe if flex pipe on stock one isn't in acceptable shape. I'm not satisfied with the execution/price of any currently on the market, so buying one is not an option.
      Split trans and double roll pin/weld the cross-shaft; replace input shaft/diff bearings and shift segments as necessary.
      Fab up a turbo->MAF intake pipe to replace the fail prone factory intake elbow the TDI is notorious for.
      Remove the factory CCV setup, and run a VTA setup in AN lines if above gets done.
      Reseal the Injection Pump before it decides to start leaking.
      Cut out the EGR from the intake manifold and weld it back up.
      Sandblast and paint any exposed brackets, lines, ect. Everything under the engine cover would be ignored this time around, as there just isn't enough time to do so.


      Basically going to be going with the flow. If time permits, it will get done, if not, it will stay as the factory had it to stick with the deadline as the timeframe til H20 is coming up fast.

      We are going to look into the engine and see how it is. The convo kit was said to be in the car for the past 5-6 years and from the sounds of it he didnt half ass anything. It had an in-line fuel heater and other things. From what we are finding now is that the engine runs very smooth and trans shifts great. It will be getting all new seals and whatnot. I am confident this thing will be free of any problems

      yeah I dunno... personally I'd never trust a veggie engine. ive seen too many failure on tdiclub...

      just check it out to make sure it's solid. you'll have a fun little gti when you're done!

      It'd be a "GTD" in Europe. This is a cool swap.

      Dropped the engine with the subframe this evening as well as the tank and lines. Now to tackle whats under the dash tomorrow for a few hrs. I plan to have a list of parts that are needed and will be ordered by the end of the week. Everything is going smooth thus far Will update with pics once johnstamos uploads them.

      After spending all Sunday rewiring his garage, adding 700 more watts of lighting, and generally getting a garage that hasn't been used as a garage in 15 years ready to go, we finally pulled it in and started. Of course we had to break in the garage and send the car off right with a burnout, with a Nesquick bottle full of diesel and some washer line for a fuel source.

      Put in a solid 5 hours from 6pm-11pmish, and got all the major parts out of the car. Would have got it the rest of the way stripped, but had to stop to rewire the faulty mini fridge. Rigging a battery charger to power it made it a quick fix though.

      Engine, trans, subframe, suspension, front clip, rear beam, tank, lines, exhaust, alot of the dash, all the non ABS parts, ect are out. Making GREAT time for working with all handtools.


      On to the boring pics everyone has seen 100x times before.







      Got lucky and the frame rail JUST missed the engine in the accident. It tweaked the water pump pulley, but thats all.







      Keep finding more and more new OEM parts on the car that must have been replaced right before it was wrecked and sat forever. New OEM axles, control arms, calipers, strut assemblies, etc.




      Aside from the rockers and drivers floor pan, the car is rust free. NOTHING near the towers, gas door, 1/4's and fenders, etc. Even the rear impact bar isn't covered like normal. Prob going to cut a bunch of repair panels before scrapping it because of this.

      Managed to get in almost 3 hours today on the car. Just need to pull the shift box and its ready to get hauled off.

      Dash, pedal cluster, all harnesses, HVAC box, and the bay got completely stripped, as well as all the body parts that are getting saved.

      Im amazed at how well this car managed to survive. Even the OEM exhaust survived in near perfect shape, the clamps came right off, and after a few taps with a dead blow, came right apart at the slip fits. Exhaust will be saved and going on his brothers beater Mk3 to quiet it up.

      Some of the unique extra sound deadening panels that the TDI's got.

      now comes for the fun part... spending money on parts needed

      plan to scrub down the engine and such as much as possible this week and hopefully have the parts by mid next week.

      With 215k on it at that.

      All the foam in the HVAC box is still there, and looks like new. OEM suspension that rides like new. OEM heatercore, bearings in the steering shaft are tight, brake lines are COMPLETELY rust free, and came off with no fuss.

      I feel like this car doesn't have 215k on it, as the seller said originally it had 140k, but cluster read 215k. Aside for the rocker rust, the car looks like it has 80,000 miles on it, if even that. It was maintained well for sure.

      Have to do the swap "stock" enough to pass through the first emissions test/DMV lookover to get the title changed over for the diesel engine, as he has emissions where he lives. Tune, fake cat, and exhaust for now.


      But after that, I'm sure he will catch the bug and want more.

      too much money spent this year on this piece.
      next year i do plan on the more performance parts (bigger injectors, intercooler, etc...)
      i do plan on getting a tune from malones this year during the fall whenever i sell my aba setup.

      rapping up the major parts list today with the last order for the intake elbow, fuel lines from the filter to ip and fuel sending unit. hoping all parts will be in next week. will need to make a small order from advance for fluids,filters and such.
