Better than 11.3's with radials and stock weight?
That is not going to be a cheap option.
Many guys that do those conversions use a stock 091 box with no problems,
but with boost and engine mods that will go low elevens life will be short.
Having a clutch that is very soft will help the trans life.
Among all the modifications that can be done to a bus box,
the replacment intermediate housing
that allows the use of a bug nose cone and shifting mechanism
is a big improvement, but adds considerably to the cost.
Unless LanD Industries in Canada is now making an 091 version,
an 8mm case-spacer and additional work will be required to adapt a Berg, or 'Morris Race engines' 002 version.
These housings range from 399 to 500 US dollars.
Other PARTS cost worth consideing are:
Albins gear set: around $1500 or more depending on their freight costs.
Albins superdiff ? $800? plus you will need additional spider gears.
Often with 09 trans, the hardening from the side and spider gears is worn off, so these need replacing too,
but this is dependant on the quality of your core.
My own trans took 60 hours plus parts to prepare:

It is a 002 trans with 091 case and a spool to replace the diff centre.
I probably have about $4000 invested in parts,
so you would have to factor in
the cost of labour,
cost of a good core,
Cost related to the US dollar now being around $1.67 australian,
and various other nightmares related to a job this complex,
like that yours will be based on an 091 and not 002 like mine.
All that sounds like a bad dream hey?
Well I hate to scare you off,
but that is th reality of the whole story.
As I said at the beginning, a stock 091 will get you on the road,
and you may preferr to upgrade each part as they fail.
The other advantage o the slow upgrade method,
is you can see if you want to make ratio changes based on how the stock ratios perform.
Another option diff-wise,
is the Peoquin torque biasing diff.
It is like the Quaife in design, and very good quality.
I would guess these are arount 1200 to 1300 US dollars(you do the conversion)
A steel hub for third and 4th, from Albins(+$200? plus freight?),
and chromolly pinion nut($66 plus freight?) are some other things that I would do.
I would say that the weak link in mine now would be the actual case.
I am not a fan of weld on braces, like the US builders do,
but there is an Aluminium version of the case that is stronger than the stock magnesium case.
Enough typing for now,
