RE: Leakdown test procedure:
Quite a few instructional examples available on Google - even some YouTube stuff.
Here's your HF instructions

Hi Jim and Matthew,im doing this swap too...dont get yourself into adapter plates or bellhousings . easy way out is audi a4 a6 quattro gearbox.remove front flanges and  ring gears if you want less weight if not they can stay.remove torsen diff and weld the 3 gears together.get some machine shop to balance that for you.put it back and there you are-mgb rwd.advantages off all that you dont need to worry about flywheels starters or clutches, everything bolts right in.mgb rear axle is 3.9 audi rear diff is 3.889 so is no difference if you wanna keep axle stock.be aware thou that diff rated just for 230nm and 1.9 tdi has around 240nm stock depending on the engine code.if i where you i would look for longitudinal mounted engine as in audi because is a lot that needs to be changed to run traverse.
 well anyway good luck whit it and ask if you need some advice.

Got any photos of that set up?

Jim, Martin is talking about a AWD transaxle with the cv axles removed and diff welded up to force all the output to the rear driveline. I don't see why it wouldn't work but may require tunnel work to make room.

Thanks guys, and Graham, thanks for the links. I think I understand it now.
I'd guess that quattro gearbox is going to be very expensive, but it could be a good option anw worth looking into.

Jim, Audi A4 1.8 Quattro(same platform as Passat) gas motor has same bellhousing pattern as TDI. Nationwide search on car-part.com shows lots between $500-$1000.

I don't think it's a good idea. T looks too wide to me.

Jim there is no way that quattro box is wider then mgb. audi a4 b5 quattro.fourth generation quattro system.available from 95-01, or later ones b6 would work aswell,they just more expensive. 1.8t quattro like jim suggested or any bigger engined cars will work as long they are quattro.really cool thing on all quattro boxes is that they will bolt on all the vag group engines eiter 4 5 or 6 cylinder.the quattro box that jim post the picture is early type generation 2 there is no torsen diff just open and manualy lockable.that box will work to but it would be hard to find.
only thing by tdi conversion is you cant go with gasoline box because of the gear ratios.diesel box on tuned gasoline engine will work very well but not the other way around.
audi a6 c6 1.9tdi or v6 2.5 tdi is another option.they are 5 or 6 speed.
there is a lot of unanswered question :like -do you gonna buy the whole car or getting bit by bit?dont know whats the prices in us but i got my conversion donor for 500 euro..whats that?650$?tell me more about and i try to give you a list of possible ways to go around.also do you plan to get more power out of your tdi or keep it stock?
about the oil filtter that matthew posted above :seems to me the engine that you got is transverse mounted.beware as i suggested you before transverse engine is NOT made to be mounted other way .to make it work you need to change oil pan ,oil pickup pipe,oil fillter housing.audi oil filter housing is pointed bit sideways that might help you with the space issue .and one more thing it is not recommendet to mount the engine without angle because of the lubrication flow.
good luck guys .

Martin, All the TDI swaps I know of use FWD motors with Toyota or Suzuki RWD 5 speed trans. Most use ACME adapters and are mounted either straight up or stock 15 degree slant with no issues. As Matt found out,the FWD motor is short and fit behind the crossmember. I think you could adapt an aftermarket remote oil filter and cooler. Your idea of the Quattro transmission is interesting. This picture shows it is pretty compact. Instead of welding up the diff can you make a spool(coupler) instead?

[MGB-MODDER]

well Jim there is a few vag group engine conversions has been done in rwd.some used acme adapters or more corectly bellhousings on ford type 9 gearbox,some uses adapter plate and ford mt75.but personally im prefer to go stock instead of inventing something .right set  gear ratios is what you need on tdi engine.
    engine are made to be slanted so maybe no issues yet,or maybe wont gonna be at all but its very easy to keep it slanted...especially on lhd mgb.right  hand drive you have clearance issues because of the steering . oil filtter:you can run some different setup im pretty sure,but i just give an option
     coupler on the centre open diff maybe,but i dont know how it would work on torsen diff.thats the picture what needs to be done.is straight forward job.

Thanks for the photos, that is the type of filter housing that is needed with a screw-on filter pointed downwards. The heat exchanger may be the same. We haven't disassembled it yet. That looks like a gasoline engine? I think that and the trans are the only real issues. Matt will have to sell the MG overdrive trans before he will have the funds to buy one of those transmissions. Anyone know what an MG overdrive 4speed goes for these days ('74)?

Jim,both of those pictured engines are gasoline.any gasoline or diesel oil filter housing will bolt on on to the every block.transverse mounted engines has oil housing pointed down,longitudinal bit sideways.just make sure they are turbocharged because you need oil feed from them.
