In my search for transaxle upgrades, I too have run across this page. Beefing up the 
input shaft is effective in it's goal, but probably isn't a good idea in the long run. Most 
likely, the reason that the input shaft is prone to breaking under heavy torque, is 
because it most likely was designed as a fusable link to prevent damage to the entire 
gearset under constant strains and jerks.

One car builder in the UK had a website up for a project car that he built in '97, and 
used the UN1/Rover V8 combination for his powerplant and drivetrain. Cranking out 
around 500bhp, he stated that he never had a problem at all with his input shaft, 5th 
gearset, nor any other associated components. I'm not a betting man, but I'd wager 
that his finaldrive had the proper gear ratio on the differential to handle what the 
motor was able to throw out to it. Which is the very problem that we have with our 
transaxles.

Allot of the information on the 'net available in English is quite limited. Infact, I've 
found that aside from someone's own journal entries about their personal experience, 
the same info found is constatnly copy/pasted from one web page to another. If you 
want to delve deeper into seeking more info, you gonna need to learn French and 
German.
