Meg 225 gearbox on Clio 200 engine

[N0ddie]

Is this a straight fit?

The 200 box will eventually give up the go again so as a preemptive move should it happen out of warranty I'm looking at sticking a Meg box in as its replacement. I dont wanna waste money buying a new 200 gearbox when it'll be getting changed for a Meg one come conversion time, so sticking a Meg one in seems the sensible option?

I know the ratios are slightly longer in the Meg box so acceleration would suffer but surely wouldn't be too bad? Could also take the opportunity to fit a diff at the same time (As the R26 boxes with diffs are hard to come by).

It will fit mate you will need megane shafts and linkage too and a mount

The ratios are a fair bit longer, so personally I would only do it short term.

For example 70 in 6th is about 2300rpm in a megane. Whereas its about 3500 in a 200.

Why not get the 200 box strengthened to be able to cope with extra power n torque??
Surely this can be done for a similar costing??

You can get a 225 box for £200. Doubt you can get a box strengthened for that?

Gear ratio is ok for our engine? ... Mmmm

you could get the gears shot peened, which would add strength, but how much wouuld be questionable.

I guess it depends which part of the box is the weak link.

Someone did look into a replacement gearset that was stronger, but i think it ended up being thousands and thousands of pounds.

i think its more to do with bearings then the actual gear set...

Cryogenic freezing treatment is the way forward:

so a case of sourcing stronger bearings? Or would it not be that simple, as in it wouldnt be an off the shelf item?

have you had any trends to the gearbox failures? like no drive, cracked bell housing, one failed gear, synchro broken???

Mostly broken synchro on 2nd/3rd I think!?!
