Hello all,
I've seen a GARRETT Turbo on ebay that i'm quite interested in, the part number is 028145762 028 129 713K -
It's from an '98 Audi A4 1.9TDI AHU engine - I too have the AHU engine but mine is a '96...
If indeed the turbo/manifold is suitable for my engine, will it offer any improvement over my original turbo? (peirburg)
Thanks!
Jack

I would think the main difference is the Audi is a 110bhp and yours is a 90bhp, the turbo will I guess fit but I don't think the manifold will be any good as the engine is mounted a different way to a Golf.
-
You raise a good point with the 110bhp...
While I basically have the same engine, mine is only 90bhp - what are the differences between the two?
Thanks

Not 100% sure but I would think turbo and a remap would be the difference.

What if I bought a complete Audi 110bhp engine - what would I need to make it fit/plumb in to my golf?
I've seen one that has the diesel pump and turbo with it but nothing else, which (if any) of my original ancillaries would suit this replacement engine? Would I need to change the gearbox/driveshafts?
Thanks!

i would have thought an AHU engine was an AHU engine wether fitted in an audi or a vw, its probably more to do with how they have tuned it.. see if the ecu and turbo are compatible with your set up, autodata is a good start to see if the ecu pin outs correspond with each other.
-
Righty, im planning upgrading my MK3 TDI so i have some infomation on the engines and turbos etc..
I will dig it out in a sec, but i do know the 110bhp engine is rare, afaik it was put in the euro spec GT-TDI models but they were not sold here. Anyway the audi turbos should fit your manifold but i dont think the audi manifold will as there is more space with it being an inline engine on the audi. I will post the engine info i have in a sec.

Tell me about this autodata.....
Also RMachines - looking forward to the engine info, cheers bud :D

Right, the turbo off the following engine codes should fit.
1Z /AHU Standard TDI engine
AFN - 110 BHP engine
ALE - Introduced post 95 90bhp
AZZ (might fit) but thats of a non tdi engine.
AAZ - KKK turbo
1Z AHU and ALE also use KKK turbo or Garrett depending on model age and country.
I think i managed to figure out that the turbos arnt any diffrent across the range and mine is fitted with the best there was for the 90bhp engine, yours should be the same as mine, the 110 is however a variable vain turbo so thats the one you want to try to get.
If you want to get good power i would start with a remap, then mabey look into the AFN turbo, I think the MK4 turbos might fit, I know the MK4 do a 110bhp non PD engine in the UK so that might fit...? Im currently looking into whether any of the PD engine turbos will fit onto the non PD, I have a MK4 TDI with a 115bhp PD engine and i can see it really brining the Mk3 to life with a few choice mods. could just be an expensive dream though. i will keep you updated on my findings, im doing some hardcore part matching and research tonight :wink:
-
man you rock, awesome ;)
Cheers for the info fella - actually I wonder can you help with regards to my earlier post about 110bhp engine replacment?
Thanks!
-
Im pretty sure, because the audi is an inline engine its slightly diffrent, i really dont know to be honnest but i do know the MK4 golf non PD 110bhp engine will fit into your car, also the 115, 130 and 150 bhp PD engines will, its relativly big job but not to hard to do.
Mabey if the mountings on the audi are the same it would fit... From what i remember of the A4 TDI engine i worked on, it was very diffrent to a MK3 engine layout. It depends what your goal actually is, if you are after power, PD is the way to go, if you are just looking to replace a turbo and mabey a quick upgrade at the same time, i would stick to your hunt for a 110 turbo. Mabey if you have the choice of a 110 engine that fits and fancy a project, it could be a good option as the later engines especialy are alot smoother and quieter as well as faster.
-
well I have a few options, links follow! - Tell me what you think..

The first is from what I can tell, the same engine as mine and the second in the 110bhp we talked about. The first would be a straight swap, how much work to make the second fit?
-
Both are AHU, that audi engine is 90bhp not 110bhp. Both however should fit, Its worth mabey you poping down to a local scrap yard and having a good look at where the engine mounts are on an A4, then compare to your golf, if thats the same and the pipe work is ok it should fit, the pipe work is diffrent on an audi but you can swap it from yours so thats no problem. If the choice is between the two, as they are the same, go for the golf one.
The only codes from the audi that is 110bhp is the AFN engine, same as the golf gt-tdi. Look out for a quattro TDI as they were only fitted with the 110 engine.
If you are fitting an AFN 110bhp engine from any car, the ECU and engine loom would need to be changed, you might get away with the engine loom if everything else is the same but certainly would need the matching ECU. And your gearbox too, audi is a diffrent box. Hope that helps a bit. :smiley:
-
Certainly does help :) Thanks!
Okay so i'm on the hunt for a AFN 110bhp yes?
I will need the gearbox, ECU and possibly the wiring loom - what about driveshafts and ancilliaries like alternator, starter motor etc etc - I assume all these will be different on the 110? (ie cannot use my original 90bhp bits?)
-
I cant comment 100% on the alternator etc.. but being a diesel and being very similar, and providing its out of a Golf, it should all be exactly the same as yours, the gearbox will fit as long as its from a golf, driveshafts should be the same too. Im pretty sure the only diffrence is the ECU and turbocharger on the engine, the block its self is pretty much the same as yours.
-
okay cool,
Then can someone tell me this - what engine code will I be looking for to find a 110bhp mk3 golf engine?
-
how about this?

-
AFN is the code for the 110 engine whether its in a VW oe Audi it should be the same, from what i can see its the only 110 engine there is. That passat engine looks about right.. but if its mounted inline its going to be more like the audi, so double check the mounts.
-
Okay so I need to change the mounts, gearbox, wiring loom, ecu - what else...?
-
Thats pretty much all, audi engines might have a diffrent exhaust manifold layout, so diffrent down pipe mabey? I cant think of much else tbh.
-
so really i'd be best gettin a full passat scrapper methinks...
-
I would say so, when i did my 16v conversion i look back and think it really would have been a total nightmare if i didnt have a full doner car to use. If you can get a scrapper its well worth it!
