    Audi Coupe Quattro 7a --> 1z TDi swap questions

    Hi there, I'd like more details on the Audi Coupe Tdi that were sold in the EU. I know they came with the 1z motor (which were later found in Vw Passat's here in 1996) and were only FWD.

    I'd like to go diesel in one of my Coupe, but is a quattro and I want to keep that - Canadian winters !!

    So, here's a few questions to start with but also looking for been there, done that experience :

    1) Is the subframe and motor mount for 1z TDi's different than the 7a Quattro's ? If yes, can a subframe of one or the othe be adapted to support the swap ?
    2) What transmission does the 1z use ? Can I keep my 01a and change the gearing inside ? If yes, what clutch do i need to use ?

    Bottom line, I'd like to keep this as simple as possible and the less cost as possible.

    Most parts needed for easier TDi swap would come from Europe and I'd like to keep that to a minimum as I would want this one to become my daily driver and be easily maintained. We got a LOT less TDi models here and are limited in the engine/car combination that were imported here.

    Thanks

    for clutch and flywheel you can use audi 80 b4 1z parts.
    when i mention the pd130 i mean is it not better/easier/more readily availble to use b6 engine

    Yep, it is different. Passat B5 engine would be a better and easier fit.

    Ok, let's say I'd want to go the "easy" route and put a 1z engine (easily available here) and bolt it to a sedan 01A transmission (longer 5th).

    What would I need from a longitudinal 1z (never had them mounted longitudinally here in America) ?

    -Oil pan ?
    -Engine Mounts ? --> would they fit the 7a quattro subframe ?
    -I guess I'll need 7a clutch and flywheel to match the output shaft ?


    Any help on what may be needed would help I'm going to Europe in september and may like to source the parts while I'm there

    Cheers

    You'll also need the matching input shaft and matching gear for that shaft.
    So you mean the input shaft is not the same diameter as the ones in 7a's?

    Thanks for the input guys... I'll look into that when I'm in front of a computer

    Cheers

    Why not use a more common 5-cylinder TDI, either an AEL or AAT? Just feels more proper in a Cq. Plus they actually have some jam, and will still return excellent mileage. I think Martin was getting 1000 km or better per tank in his sedan.

    Also, does that 01A bolt to a 4cyl or not? I've heard the drilling was meant for both since found in both applications...?

    I found out that the 5th of the 01A DGW or EEP is 0.659

    That probably be enough to make decent rpm on the highway with 4.11.

    Is changing the 5th gear impossible too?!

    Other question is how to find : 012 311 361 CF

    Thanks
