Maybe a silly question, but has anyone ever looked at flipping the diff on a Passat 1.9 TDi/5 (or 6) speed g'box and swapping the whole lot into a T25?
Just a thought...

our gearboxes have an offset diff so can't be flipped, but I don't know about the passat box....but I bet syncronutz have checked it out and decided it couldn't be done

The casting is asymetric so no it can't be done unfortunately.

I looked into this about 10 years ago.It can be done but will need machined parts and custom drive shafts.Cost and hassle prity much outweigh a custom T25 gearbox plus then you either need an adapter plate or fit an upright engine.
I have seen a few audi boxes used upside down!
I have also owned a 3L V6 T25 that ran anti clockwise on an audi geardox.
Best performance ever but quite a fuel bill.Never got to strip it to see exactly how everything was done.This was a conversion done by a company in Joburgh(SA)

Hi,

Was thinging of doing something like this this as theres an audi 80 sitting in the field accross the road. Do you know what boxes are suitable was there an audi box with removable bellhousing or was it just an adapter plate.

Thanks
