[Discussion] Gear Ratio for 01E & 01A

[lorge1989]

It was more than I would have cared to spend, but considering I needed a new 1-2 collar anyways it wasn't too bad to upgrade to a real setup (and doesn't have a 1-2 syncro collar). The B6 3.0 / RS4 gears were free to me, so that knocked a big chunk right off the top.

Is it running yet?

[speeding-g60]

yep. ran for a little bit and killed the motor.

he is building a new motor now.

Bumping this thread while I decided what to do. I'm building a Passat 4-mo with an AEB 2L, Comp 5558 BB and an 01E. Picked a sub-100k mi 01E from an '02 Allroad and I have a B5 S4 01E that has some bad bearings/races (pretty much select parts only). So with a the power band around 4500-7500rpm range, I'm looking to run the Allroad final ratio of 4.375 and gears 1-4 with the S4 5-6 to get back to some decent cruising rpm range.

Final: 4.375
1st 3.75
2nd 2.06
3rd 1.42
4th 1.07
5th .82
6th .68



Couldn't find the same gear ratio calculators everyone else used. I used one from Weddle Industries.

There is not much of a difference (<7%) between the 6th gear in the Allroad and the S4. It's been my experience with the 4 cylinder cars, the benefits are negligible
.

[Crispy222]

Yeah about 200 rpm (3000 down to 2796). Its basically free and its being torn down to make sure nothing else is wrong.

I'll revive this thread a bit, I have a 1.9TDI with a 6spd gearbox, is there any way to get an even lower geared 1st gear and a slightly longer second gear and also a lower geared reverse in these boxes?

[Scotty@Advanced]

changing Reverse gear is not an option at least not a feasible on.

Regarding first and second I can have those parts made, but the cost is high all things considered.
