Since doing a few mods to the engine, I've been considering a manual conversion.
Do I need to stick with a 2.5 box or would a 3.0 make more sense? (215 bhp at last R/R)
If a 3.0 box should I find a prefacelift doner car for the clutch, Bell Housing and cylinder slave etc etc or will a 3.2 be ok?
Presumably the loom will take the conversion and I'll have to get Tech 2 to tell the car it isn't an auto any more?

Any ideas?

its not the bhp mate
its the torque 

i think the r25 box is good for 250 pounds foot 

I thought they had gone metric  :-/ shouldn't that read Nm (Newton metres) ?

The R25 is the box that is fitted to most manual 2.5TD.  Although it has a different bellhousing to fit the BMW engine.  This is also fitted with a dual mass flywheel.  The best bet is to find a 2.5td breaker and use all the parts from that

Yup, i used to say go for the R28, but as i have been corrected the R25's are fine and will last ok. Not like puting an AR25 behind a 3.0....

If your going to abuse it, and use on a track the R25 won't last long, but for everyday use it should be ok

Thanks Tunnie and Tigers - I'll stick with the R25 - it's going to be for everyday use.

Cheers and Happy Christmas!
