Thanks for the good answers.
It's a big help for a newbie.

The need for a gearbox mounted on the transaxle would be a higher top speed maby?
And I think it would be easier to mount a gearbox to the transaxle then make new drive shafts.
It would also, maby, be possible to use a Prius transaxle with a rwd car.

Do someone know the top speed you can push the ...

Is it possible to mount a gearbox to a gen 2 prius transaxle?
Is there any project that has done that?
Is there any numbers in on how many kw you can get out of a gen 2 transaxle with a gen 3 inverter runnit both motors at the same time?
Thanks.
