This kit is interesting. I've talked to an experienced workshop about it, but they dont think it is possible to do the conversion without removing the gearbox from the car, given that the internal fork (AKA gear shift rail) needs to be changed. Are there a description around anywhere of how to perform this particular step without disassembling the gearbox?
I am really sorry for the delay of response. We do not accept MC as of yet, we opened bank account at Citfin, which uses ING Bank and so the paying should be easier.Radim,
I sent you a PM a few days ago. When will you be accepting MC payments?
Yeah I read that, but I can't tell them 'you do it through a hole', I would need to give clearer instructions than that!See post 25 & 26 in this thread.
This sounds like a really good idea ... since I'd like a 6th gear which is as long as possible, the 0.59 ratio would work as a perfect 'overdrive' for motorway cruising. There would be quite a big gap between my 5th (the standard 0.75) and 6th, but that's OK.Placed my order for the kit this morning.
A .59 6th gear will be a bit longer than the .622 5th I am running now. should be nice with the stock .756 ratio for 5th gear. Fills in that hole I have now from 4th to 5th (.622).
Will post more as this progresses.
My 1st to 5th gear ratios are as above, but since my wheels etc are different diameter, these result in different speeds. So 60mph = 2205rpm for me currently in 5th. A 0.59 6th would be around 1734 at 60mph, or 2600 at 90mph....

Your gearbox could be modified as shown in the diagram.My 1st to 5th gear ratios are as above, but since my wheels etc are different diameter, these result in different speeds. So 60mph = 2205rpm for me currently in 5th. A 0.59 6th would be around 1734 at 60mph, or 2600 at 90mph.
Yes, we know that even bigger tires exist, but the diagram is for displaying recommended changes of ratios. If we were using different circumferences, the diagrams wouldn't be comparable to each other.Just for reference, a tire with a circumference of about 185cm is what the Mk3 and B4 cars run stock. The Mk4s are about 199cm.
The CTN code transmission is used on the Mk3 and B4s, it has a taller final drive ratio that effectively makes up for the tire size difference between the generations of cars.
So the numbers for the CTN code (engine RPM vs. vehicle speed) transmission are correct on your graphs. The later cars with the shorter 3.39 final drive have larger tires--~199cm circumference. Those graphs could use a change
Is there a plan to offer a .622 6th gear? I think with the stock 5th at ~.75 that would be about perfect.
Depends on their labor rate, doesn't it? What do typical shops in your area charge for labor and how many hours do they charge for a clutch job? Guess you might want to ad 1 to 3 hours to do the kit.So the question for me is what would most shops charge to install this kit along with a clutch (just labor).
It would also depend on whether they manage to figure out how to modify the gearbox while still on the car, or if it is a gearbox removal & disassembly job.So the question for me is what would most shops charge to install this kit along with a clutch (just labor).

Looks like my kit is in San Diego! Found a note on the door from FedEx, they have a package that requires a signature at the delivery address. 10 days travel time, exactly what we were told to expect. Anita will be home to sign for the package today!John Jackson, did your kit arrive yet?
It's only the standard 1.4TDI rather than the super-high-mpg 1.2 variant (they weren't imported here). But I'm happy because I've wanted an A2 for a decadeOh man Mike, i Just noticed you drive an A2, yummmmmm.
Car goes to Matt-98AHU on May 19. Plan on leaving the car for a week, so Matt can "play" with the kit. At the same time, Mk4 shift system will be installed. Had a look/feel at the Mk4 system installed in his (Matt) car at the Las Vegas GTG. Matt will also address some other items at the same time as future "project improvements".john.jackson9213, when is this going in? Are you going the install route without pulling the tranny?
