First off, how strong is the 325 box, many reports of broken ones? What kind of torque are they good for?

secondly, are they ntegral bellhousing, or is it removeable?

cheers

Gadjits sending 383bhp through a stock getrag gearbox, refreshed mind but still stock :cool:

I've run over 1.3bar on mine and it's still working, ok a little rattley these days but still going strong!

Clutch is the weak point, then driveshafts, diffs, prop etc

It´s integral .

And they have been beaten with more then 700lbs.
So they are good if refreshed.
With great challenges comes great engineering.

excellent, had hoped the bellhousing would be seperate, but an adaptor plate might be ok if the input shaft legth works out, Ill just have to get one and see :(

700lbft sounds like enough :)
