Yeah - I got new 3rd, 4th and 5th. In the 020, 1st is machined from the actual pinion shaft, and IIRC 2nd is machined from the input shaft. That is why it gets expensive to get all 5 gears in new ratios. But 3rd, 4th and 5th slide on and off the shafts in pairs, and thus can be changed - either one, two or all three of them. I don't remember exactly the parts numbers I got, and I'm too lazy to look them up. But the selection is here: http://www.mts-motorsport.com/epages/61752271.sf/de_DE/?ObjectPath=/Shops/61752271/Categories/Getriebetechnik/Gangpaare/%22VW%20020%20/%2002K%20Getriebe%22 Note - 4th comes in two varieties, depending on whether it is a "16V" box (24 mm. inputshaft) or regular box. MTS produces 4th gears for both.
Sure. I changed the speed to mph for you guys. What I got is the orange line. Stock 16V box is the yellow line. My previous config - 2Y w. 4.64 FD is the blue line. And the grey line is just for reference a full motorsport gearset from MTS as well. Dog engagement and all. It actually matches one of SQS' sets quite good. 
Lastly I fiddled the spreadsheet a bit, so you can download it here: http://files.lbrt.dk/Transmissions-US.xlsx The change from kph to mph and general translation was real quick, so please report any errors. Brgrds Brian  Edited 2 time(s). Last edit at 08/13/2014 09:12AM by wildert. |

Hör du Brian-putten, sötisen kära Wildis-ert min, är det bara mig som är så gammalt och styv och dum i pannan att jag måste har all ting som jag är van----eller är det nåt som fattas på x axis? Du har nu MPH upp o ner ^ but shouldn't there be something like RPM on the > this axis?

Det kommer an på hvordan grafen skal bruges. Det kom sig af at jeg primært ville se fald af motoromdrejninger fra gear til gear i mit regneark, samt at jeg sigtede efter ca. 170-175 km/t som topfart i femte gear på et 195/50-15 dæk. Så grafen viser hastigheden af bilen i hvert af de fem gear ved en fast motorhastighed. Det gør i bund og grund det samme når det mest handler om at sammenligne gearsæt. And in case that the Danish was a bit hard to read: It depends on how/what you want to use the chart for. In my spreadsheet I specifically wanted to examine the drop in rpms from gear to gear in different configurations. At the same time I was aiming for a top speed of around 170-175 km/t in fifth on a 195/50-15 tire. Thus the chart shows the speed of the car in each of the five gears, at a set engine speed. It sorta does the same thing in showing the different gearsets for comparison. Brgrds Brian

That is basically a 2Y (16V box) I think, with the tall 2nd. Obviously it really depends on what you are going to do with it, and your engine characteristics. All of the below is based on a 7500 rpm rev limit, which is my reality. You will get a nasty almost 3300 rpm drop from 1st to 2nd, but if it is for stage rally, and the roads in 'Murica are as fast and straight as I keep hearing, then that may be of less consequence, since you'll only see 1st at the start line of each stage. On the plus side, the drop from 2nd to 3rd is only 2000 rpm. For a box made from stock parts, that could be much worse. I don't know the redline of your engine, but the topspeed at 7500 rpm with a 195/50-15 wheel (which is possibly small compared to your reality - thus you will get even higher top speed) is in excess of 120 mph - is this really relevant? If you only rev to 6500 (8V maybe?) then the numbers get better. 1st to 2nd is "only" 2850 rpm, and 2nd to 3rd is just under 1800 rpm. Top speed is around 110 mph with the 195/50-15 tire.

It's 19% added - so if you subtract 16% (multiply by 0.84) from the amount incl. VAT, you'll get the ex VAT (Mwst) amount. Brgrds Brian

It is 25% in my neck of the woods - so no complaining... Brgrds Brian
