stock 5 speed power handling
Does anyone have a rough figure of how much the stock 5speed box from an nb8a can handle? Or is it a case of driver style and condition of the box?

Both Ian and Les's NA6's are making around 200kw.
Les's 17 year old box is still fine.
Ian's is more of a race car with an aggressive diff and he finally broke his 17 year old gear box this year.
His Kaaz diff didn't last any where near as long.

If you had access to a car like this, would you take it back right away? Neither would I.

is it difficult to switch 6/5 speeds between cars (e.g. are the mounts similar?)

That was a full throttle roll on from 80kmh - bang. Pulled out to overtake a truck.
Accelerating hard in 5th to overtake can cause that even with probably half that power.

I've nearly destroyed 3rd gear in my 5spd....apparently the 6spd from an SE has stronger gears
