No way can these trannies hold up to 300 hard driven HP in my humble
opinion...
Gently driven without a pile of extra weight, they do ok (no capital letter
ok here) overall with the 265 hp Subie 3.3..
I also have heard from some reliable Euro sources that about 200 hp and
lb/ft of torque is about the limit they suggest.
Trans cooling is a must for big HP in hot climates as well. 175 deg F or so
is a reliable max safe temp.
My Turbo Zetec is about 180 hp or so with 200 lb/ft of torque I am told.
I run Swepco 210 and so far its fine.

Sorry, it is a 2WD. Trailer brakes would make good sense to me. Seems that I
saw on the Zetec conversion site that the limit of the stock tranny is 300
BHP? That seems a bit high to me and maybe I could see 225 BHP and no more
than 175 ft./lbs. torque as being the limit that it might take and then only
with synthetic and a heavy duty clutch. Any thoughts on that?

Don's right ..
trailer brakes would make the whole affair about 75 % better and safer,
over no trailer brakes. ..
in terms of braking and braking while cornering.
stress on the trans under load ..
if you're real nice to it , it might be all right.
A trans speicialist might chime in.
I don't think it says if this is a 2WD vanagon or a Syncro AWD one.
some factor there on the trans I'd think.
