O2C gearbox (golf rallye) as fwd

[Gtom]

I somehow have ended up with one of these gearboxes for my mk3 1.8t project. It was advertised as a O2A from a mk3 16v and on the cv cups they have O2A written on them, it's only when I put new and old side by side I noticed some differences and then finally found the casting I.D.

It's now fitted in the car but driving it is a long way off so I have no idea whether it's going to be any good or not? I should have around 210-230bhp, is it liable of handling it or should I be on the lookout for a O2A?
