    Ive been wondering if any one has any knowledge of this type of conversion being carried out
    the thought has crossed my mind as i have been getting a bit fed up of the tip tronic auto in my car

    I once carried out a conversion from auto to manual on a nissan 200sx which was pretty easy

    From what I have learnt recently about my manual S4 I would guess there is differences in the Quattro system as the oil is different between manual and auto rear differentials ( a minor point) which leads me to think there are certain differences.


    I am by no means and expert on the subject but your Nissan would have been 2WD I assume?

    Just at a guess i recon you'll need to swap the rear diff as well and maybe the ECU or get the auto side of it mapped out so no faults are displayed.

    Along with the obvious trans tunnel, centre console and bulk head mods.

    with a whole donor S4 would there be differneces between the B7 & B6 model to do this swap

    usual items brake and clutch peddle, gear stick and centre consoul, the prop would need done and likley the diff, if the diff was not changed it would affect the cars acceleration and top speed

    also as mentioned the auto ecu would prob need switched off or removed, the main ECU would need some sort of bypass for the park/start

    Kind of defeats the point of the conversion, but would it not be better just to sell your existing car and buying one with a manual gearbox? To me it seems very expensive and time consuming, but then projects are more rewarding and interesting, these modern Audis are harder to chop and change than my old Series IIa Land Rover :p.

    From memory some research I did for a manual S6 a while ago, you would need gearbox, clutch and flywheel adapted from a V6, rear diff, brake servo, pedal box assembly, engine ecu, modification to wiring looms and ecu, recoding ignition engine gearbox and alarm system as they are all connected, plus other things I'm sure..... A lot more work than expected and probably cheaper / less hassle to fid a manual S4. Though of you do go ahead a build thread would make great reading :)

    I know, it's a tough decision but I've already kept it 1 year longer than planned.. I'll put it through its MOT in March and then see what happens.
    Looks like a possible SRS meet in December, might go along or maybe just meet up local sometime if you want. You still need to witness this thing now it's mapped.. :)

    It's actually quite simple to do, you need everything from the flywheel back including at the very least the ring and pinion set for a 6 speed, the shifter box and pedal box assembly master cylinder and clutch lines...... Other than that there is a bit of wiring and coading in vag-com. That has to be done to the tcu before the auto selector is removed and the abs, and tach..... Then everything bolts right up! I have been talking to a local indy shop that is audi certified and along with the cost of pulling the motor it's about 1500 extra in labor... I got quoted 15000 parts and labor for full chain service and doing the swap with a jhm stage 5 clutch
