But to get much better acceleration, the Audi 2N's close gearing is perfect.
Although the swap over to an Audi 2N transmission is relatively easy, it isn't a 1 hour job. You should have some automotive skills, if you plan on undertaking this yourself.
And it is highly advised that you have the Bentley manual.
Compared to the Fox 4-speed transmission, the 2N 5-speed is at least 2 seconds quicker to 60 mph. It also provides gearing to allow the Fox to HAUL ASS from any point - just down shift until the revs are in the power band. With the 4-speed, say you're in 2nd at 6000 rpm, when you up shift, it takes you all the way back down to like 4000 or less ! Yuck! Your power band won't start again for at lesat 500 rpm, which takes a long time to achieve with a tall gear and no power.
Follow the Bentley manual instructions for removing the transmission from your Fox.
Once removed, remove
the interior console around the shift linkage (this maybe found in the
Bentley manual, but if not...)
Replace clutch as per Bentley manual. Be sure to clean all clutch friction parts with brake parts cleaner, to unsure removal of any packing grease, etc... (ANY residue left on clutch friction parts, including from fingers, can cause slippage, which can damage your new clutch). Also, before installing new clutch, check for signs of leaking from the crankshaft seal. If at all doubtful, replace that seal as well. Oil leaking from the engine will damage the new clutch too.
Replace the mainshaft seal on the Audi tranny, as well as the flange seals per Bentley manual's Fox instructions (same concept, slightly different parts).
You can use either the Fox drive flanges, or the Audi ones. Your choice, same size.
Drain and fill the Audi tranny fluid BEFORE installing into car (much easier this way!!).
Install the tranny per Bentley manual, using correct torques for stock Fox. Before reconnecting CV axles to drive flanges on tranny, be sure to repack each flange with Moly grease.
On the tranny, install the linkage pieces that are attatched to the tranny shift rod. Install the Fox in/outside rod on the shift linkage. (do not tighten bolt holding it on!)
Adjust clutch cable per Bentley manual instructions.
Back inside the car:
On the Fox in/outside
rod, tilt it sideways, so that the left side of the part that would connect
to a lever is pointing up through the top of the tower. Cut
off the little piece of metal on that side (small ledge, used as
a 5th gear block out on 4speed cars). Install Audi shift lever to Fox in/outside rod (Fox part may be able to be used, I dunno, I used to Audi one cause it's straight, 4speedd one is bent and looks like it would be
uncomfortable with a 5 spd). Slide shifter ball-joint onto rod, then spring, then spring retainer and circle clip. Reposition circle clip back into it's groove on shift lever.
Adjust linkage so that, for 3rd gear, the shift lever is in the middle of the tower, pointed forward.
Now here's a bit of other info too. Rememebr that reverse on your VW USED to be push down, go left and up. NOT any more.... Now it's UNDER 5th gear (no need to push down anymore).
Reinstall center console around shifter. Reverse removal. Enjoy!
Drive car, paying attention to shifting lever movement, adjust as you feel necessary.
The shifting points feel more natural, and the car is a LOT quicker to 60 mph now. AND on the highway, it revs about 2700 RPM at 70mph! The best of both worlds!!!! Plus, you can kick it down to 3rd on the highway (between 60 and 70 mph), and literally SHOOT ahead of traffic up to about 80. Very nice!
Big thanks to Josh, a fellow VW enthusiast for this information!!
