looks for guidance on TDI swap.

Hey guys I have an old 80's toyota. The engine seals are going and I was thinking about putting in a TDI engine. I found this forum by searching TDI engine swaps as I know they're popular with the smaller 4x4's and I found the thread below
http://www.vwdiesel.net/phpBB/viewtopic.php?t=13075Sorry for the newbie question but I am curious about the electronics. What are the different versions of the 1.9L Turbo ? As well In that thread it made it seem like the more modern ones are harder to swap. I'm fairly handy so I can make some new engine mounts do all the pluming for the rad, turbo etc and I'm not new to the modification game.
Its just I'm trying to understand what hurtles I'll hit when it comes to the electronics. If I use my stock tranny I can still use my speed sensor from it and its a RWD car so it shouldn't be an issue. However can I just wire up something for the ignition from the body harness and be alright. Again sorry for what may be newbie to you guys.

The engines you could most easily use are 1Z, AHU, which are both very similar, and the ALH. If you don't want electronics to worry about, you will need to get an M-TDI pump built. There is also the PD engine, but it has to have the electronics, and would be a harder swap. The speed sensor shouldn't be a problem. All I did is take the + coil wire and hook it to the fuel solenoid. The senders for temp and oil may not be compatible, so you may need to somehow put the Toy senders on. Then you just need a starter wire.

may be a stupid question but why would I need to go to a mechanical pump ?

So you don't have to worry about the electronics, and have to get the ECU reprogrammed to get rid of the security, have the original dash cluster and key. I'm not sure, but it probably wants input from the tranny and other circuits as well.

ahh fair enough, didn't realize the ECU has it tied to the dash cluster and key. Tranny I'd be surprised on the manuals.
is there a list of engines somewhere I could reference which engines you mentioned above?

Sort of. I don't think the dates are right for the US & Canada as they had similar engines at different times. The AAZ's weren't imported to the US, but were to Canada, and I think were available until 1997. In 1997 however the US had TDIs. I don't know the exact chronology of everything, so I won't list everything.

fair enough. I'm actually from Canada. I've heard the US wasn't getting the 1.9L's while I think Canada has had them since 95 or 97 I think.

If you want to see the differences between an AAZ and 1Z/AHU TDI, with the exception of the pump, look
here. I turned an AAZ into a 1Z/AHU equivalent. The 1Z and AHU were practically the same engine, and obviously very similar to the AAZ ,with different pistons, head and injection pump though.

The AHU does not require you to tie into the instrument cluster. It does not have an immobolizer on it iether. There is a small handfull of wires that go in to the cab, such as brake pedal switch, clutch pedal switch, TPS, cruize control and glow plug light. It's mainly a stand-alone control system. The ALH is a bit more complicated. The M-TDI is a good route too. Looks like there is a handfull of them for sale in Ontario under 2000.00. Check
www.car-part.com, 98 Jetta TDI Engine, Canada. Those wrecker engines would be incomplete - ie - need TPS, MAF, hanress, ECU, etc extra, but good for a M-TDI build. Expect to pay about 3500 to 4K for one with everything if you want to stay electronic.

so the AHU is the 1.9L 95-99 TDI engine in Canada ?

no 93-97 is aaz although i've heard of some '96 and '97 as TDI but maybe only in passat's and the engine code is 1Z??? in jetta's 98 to mid '99 it was the AHU. after that it is ALH going to around 2k5 ish. europe had the PD engines way before us... they always get the newer and nicer technology faster!!!! :cry: but they are the guinea pigs :lol:

And don't forget you can convert an AAZ to a TDI with a head, pistons IP and injectors.

If you do a M-TDI, you won't ever have to worry about limp home mode, unless your line or lifter breaks that is.

this is what we call the 'very rough limp home' :lol:
