Best gearbox?
Hi, I'm sure it's prob been asked before but what is the best gearbox to use on my Rs turbo, I'm gonna be running 250-280 Bhp so want to be able to cope with that sort of power, I'm still cvh so what is the most straight forward/ swap option? Also any other pointers/mods would be appreciated? Different 5th gear? Etc cheers

IB5 out of a mk5/6 escort.
Ka 1.3 gearset
Use the FD out of the IB5 and fit the LSD from your standard box. This will give you slightly taller gears which I prefer, more sensible rpm at 70mph.
(If you want identical ratios you'll need to source a PUMA 1.7 FD and the lsd will need modifying.)
This is a direct swap, bigger bearings as standard, more webbing on the box making it stronger, and its not like most BC boxes which are 20+ years old and suffering from metal fatigue.

I'm looking into buying all the bits but seems like such a ball ach unless you know how to build a gear box, 3 old boxes just to make one good one if you got the time guess it's worth it

Regardless of what it changes, its still a BC box which are 20+ years old and probably suffering from metal fatigue.
If you use an IB5 you already have those bearings (captain obvious) plus extra webbing on the bell housing to make the box stronger.

Sport and Street are front starter but the casing is offset and requires a lot of modding of the cradle to get it to fit correctly.
Better off using a casing that is already front starter and not offset (Escort Diesel van non turbo, MK5 Escort CVH IB5).
