B1 passat; 4 speed to 5 speed swap (1.6td)

[robertoal]

First off: i'm dutch, therefore my english isnt that good; but try and bare with me please
Second after reading tons of information on this great forum;

I am potentially buying this passat, but there are one or two issues with it, the main one being it has a 4 speed transmission at the moment.
Because of the extremely high fuel costs, and because of the terrible noise (its a GC i think, its probably revving at 4500 at 120/130 kph) it makes, i would like to kwnow what i'd have to do to replace the current 4 speed gearbox for a 5 speed one.

The engine is a 1.6TD.

1. Which gearbox would fit? Problably one of a audi 80?

2. What gearstick unit should i use? (found you could use the old 4 speed.. is this true?)

3. What gearlinkage assembly should i use?

4. The current owner has put a brand new clutch/flywheel/pressureplate in; could this fit in the new gearbox?

5. Is it possible to use the old axles?

6. Will the old starter motor fit?

The car its all about:




Thanks in advance for any answer

First of all, welcome! I don't think too many people on here will be able to help. The B3 and B4 Passats have transverse mounted engines, and the earlier models have longitudinal engines. I would think any early VW longitudinal transmission would work. I found a list from a google search for you.

As far as the clutch, flywheel, shift linkage and clutch linkage go, I do not know. I do know that all 4cyl VWs until MK5s all have the same bell housing. With the right flywheel and clutch set up you could use a 1.6l motor with a 6 speed 1.8t transmission. It will just take some trial and error for you.

Indeed found this site earlier, but forgot that in other countries the name isnt't passat.. but quantum. (or fox instead of golf)

A golf has a transverse engine. 'my' passat has not. So i would think this site is of no use to me?
Thanks anyway though.

6 speed would indeed be great, unfortunately i'm not a mechanic and need a fast en neat swap; need it up and running before my vacation.
Best case scenario: 1 day of work.. thats what i;m aiming at.

A Fox is longitudinal just like your car. The Golf and B3/B4 are transverse.

The 6 speed comment was for reference, to give you an idea on how basic VW kept things

It's so much the wrong site but the wrong forum.
You would be better off on the Dasher (Passat B1)/ Quantum (Passat B2) forum.

As it has been pointed out, the B3 & B4 Passats have transverse drivetrains vs. longitudinal for the B1 & B2. The VW Fox is longitudinal as well but the transmission configuration has some differences to your B1 such as the shifter being incorporated into the console. The 5-speed on the VW Fox was available in the US only after 1993 from what I can recall. The Audi Fox is a closer relative.
