Could buy the second hand box and get it apart for the long 5th gear and put new syncros in while its apart? Leaving you still able to drive about until your ready to swap boxes then you could rebuild the poorly one and sell it working to make some money back?

I have an s4c. For the money there a good upgrade. Not as quick up the gears as the s80.

Nice compromise for improved acceleration and cruising.

Mine is from an em1 vti. So has no lsd although i personally prefer how it handles over the stock Honda lsd. I find the lsd likes to pull in straight line if your on the gas while cornering.

Open diff imo corners better in this case.

Depends on money mate. S80 gonna sting you around 4-500 quid. S4c or y21 both the same. Gonna cost 150 quid.

Be careful who you buy from though.

I've had 5 gearboxes on my car before I got a good one that selected all gears and didn't whine or crunch
