Are you calculating that with the CQ 01A, or the sedan 01A? The sedan has a slightly taller 5th gear than the CQ.

Well, it'd be the 5th from a DGW 01A from a 1996-1998 A4 TDI Quattro... Which 5th is 0.66... Very tall.
There's O1E 6 gears that the 6th is 0.56!
I'll calculate with stock 01A... But thanks I had notice it was taller on the Sedan but didn't think of making the calculations I think it'll Rev too high.
Do you know if I can swap the rear diff ring and pinion from a B4 into our B3 casing? There 3.89 instead of 4.11.
Thanks

It has been tried, and can't be done. If you can find a UrQ rear diff, that will give you the final gearing you are looking for. I know a couple people who have put them into B3's.
From what I have found, the B3 sedan has a .769 5th gear, and the CQ has a .838 5th gear. I'll be dropping in a sedan 01A into the CQ I'll be picking up soon.

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.Find me on Instagram @pry4sno

You'll also need the matching input shaft and matching gear for that shaft.
Thanks for the input guys... I'll look into that when I'm in front of a computer

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
