Hi all is it possible to fit a megane 225 6speed box to a 172 cup if so what's involved

This thread will get locked, do a search, answer is no unless you have lots of money for little gains

The bolt pattern to the block is different, either use a later block as well, or redrill yours.

the subframe needs modification too iirc

Indeed, plus new shafts etc.

What kind of shaft does it fit? And other modifications?

Pm andyrg, he's done a few 225 conversions

nothing off the shelf, you need some made.

Fitting the 225 box onto a f4r730 block will work but you wont have many bolts to secure it, ideally you want a f4rt block and rebuild your engine into that. Custom shafts needed, custom rear mount and fabrication to the chassis leg

Am I missing the point here? Driven a 225 and the gearing is noticably higher than the clios, presumably to take advantage of the mid range torque. Can't see that working in the revvy clios. Wouldn't you be better off fitting a 197 box?
