Fiting 2.5 TDI in Urs4 AAN

[caterpillar]

very thanks for this info Urs4boy.....!! nice to know the differece...

[FabS6]

Very very VERY nice project mate! Are you even upgrading the engine? Stay with the AAT 116bhp quattro gearbox, it has the 4,111:1 final ratio that matches the S4 rear differential. The AEL 140hp from the A6 c4 uses a longer final ratio...OR swap the rear diff too as a solution. I want the AAT gearbox on mine to reduce consumption, but I will stay (for now) with my S6 gasoline 2.2t with some mods...I also planned to make it diesel with a tuned AAT or AEL hopefully with over 300bhp....but for now I stay like this with my LPG system too. Cheers!

Actually AAT is rear diff.

Pa zemo mislim da bi tebe kolega iz Crne Gore razumio da si napisao to i ovako na ovom jeziku jer atest nije engleska rjec

Ali super da se malo nasmijemo

Fab i think u missunderstand my point?
Ma nema veze malo smijeha nije na odmetu

[Giacomo]

what about making a kind of reverse job?
Building a 2.5 stroker tuned petrol engine with a BIG turbo and a LOT of hp starting from an AEL A6 quattro chassis/transmission?
Does the engine needs to be pulled out from the car and opened?

Giacomo said a perfect solution.. but I kow what is your (our exYU) problem .. newermind..
if you will using urS4 gearbox on AEL you will get much quicker car than stock A6 2.5TDI , but other thing is very low top speed ! , maybe 170km/h , actualy try to drive your 2.2T on 4000rpm in 6. speed ! that will be TOP speed !
good thing is that 1. , 2. , 3. speed are the same on both gearbox , so your 2.5tdi with CBL box will be the same like DQT box , 4 , 5, 6, will be much slower !

now is one other question... maybe you can use TDI FWD gears and put it in CBL box..
don't know if it is possible..

[Majorcina]

Exacly rs200,u know the situation over here
170km is fine,since top speed in my country is 80km/h
The car will be used as daily and for traveling throw country

[rs200]

if the car will be used for traveling than TDI box could be much better option.. if car will be used only in town , than TDI box and Us4 box have NO difference !

Hey!
Some 5 years ago I made this kind of job.
URS4 2,2 20vt was replaced with 2.5tdi AAT.
For me this kind of job took 20 hours - I drowe my petrol engine in garage and after 20 hours I started diesel engine. Plus some more hours to put all the bumpers, and saloon parts back. But I can advise you to use both intercoolers - in diesel and petrol cars they are placed different - one is under left wing, one under right wing. Only what you need is a inlet manifold from volvo diesel - it will be reversed. Nice cooling. After you can go to bigger nozzles, vnt turbocharger and 1.9tdi ECU and you will get a rocket with low consuption.
About gearbox - if you will choose to put an front wheel drive gearbox to URS4, it will be a porn.
Better take a gearbox from diesel quattro - A6 C4, A6 c5 etc.

There were a question about stroker and diesel gearbox - normaly me and my friends vere using these gearboxes for our projects.

If you need volvo inlet, I can provide you with it, just give me a PM!
Good luck

rs200,u know that my country is small,so the "trips" would be 100-150 km long with average speed limit of 65 km/h
Gunto u got pm

Hi. I have just finished my AEL swap in an URS6. I used DQT gearbox from an Audi A4 b5 2,5TDI quattro. It has the same 6th speed ratio as the AEL gearbox and is not very hard to find...

[Majorcina]

Hello,that gearbox and engine its even more rare over here...Here we got nothing...
