Jamie Porter, The Alfa Workshop, has put one in a 75 which is rear wheel drive. I don't know what box it is, but it worked well when I drove it.
Maybe call him, he's very approachable, or perhaps someone on here already knows and will respond soon..
I think that would probably use a standard 75 gearbox, which is a Transaxle, so probably not a straight-forward implementation in a TR6! Maybe call him, he's very approachable, or perhaps someone on here already knows and will respond soon..
As far as I know, all the RWD Busso's were transaxles, so a bit of bespoke engineering might be required to fit a conventional gearbox on. Might be worth posting on Alfa Owner to see if anyone on there knows (I seem to remember rumours of a Busso engined 105 coupe, but that might have just been my imagination working overtime)
The only production Alfa that used a gearbox directly mounted to the v6 was the Alfa 6 saloon. You might find one, but it will mean a trip to mainland Europe. Another option is to engineer a kit to fit a BMW 3 series gearbox onto the engine. I once saw an Alfetta GTV6 with this conversion, so can be done
All things are possible and putting the later 3.2 V6 which from the factory was installed in a transverse lie FWD platform into a longitudinal RWD setup is possible.
The earlier 2.5 V6 (and 3.0 in the 75 and South African GTV6) in a RWD platform utilised a bellhousing linked to a propshaft and rear transaxle setup (similar to Porsche 944 setup) - this was brilliant in terms of 50:50 weight distribution and reducing unsprung weight with inboard rear calipers,etc bu the inherent compromises of the design limits its attractiveness for your setup.
The South African Alfa racing fraternity often used both versions of the Alfa (Busso) V6 and ditched the rear transaxle and used either a BMW M3 gearbox or similar and an Alfa 6 rear differential.
Same V6 has been used in an Alfa 105 chassis - see https://www.alfabb.com/bb/forums/engine-conversion...
Beautiful engine but quite heavy which may affect the balance of the car; here's my one track car with a 3.2 GTA engine in an old skool GTV6; the 105 coupe on the right has a 75 twinspark engine.

The F.W.D Alfa's have always met my (limited) needs as road cars, but I can't help wondering how the 164, 156 and 916 GTV would have been received if they'd had that engine in that config.
Glad to hear I wasn't dreaming re: the V6 105 conversion.

Man. That 106 GTV with the TS engine.

I am interested in installing an alfa 3.2 litre busso v6 into an old car.i want convert it from transverse to longitudinal mounting , so it serves in a rear wheel drive configuration. Iam thinking of using a zf s6-37 manual gearbox.before commiting i would like to know if there better six speed manual gearboxes that can better serve in this situation. A durable box which us eaay to mainten when such a time comes would be most helpful. The other issue is the actual mating of the box and the engine. Any hints are welcome. If any of you know a shop base in the uk which can do this job , please give me that information.
I see this is an old thread but I have done this Alfa V6 RWD swap:

Not the simplest swap, but a lovely engine.

Nice! It just about fits! I always wondered if it would be possible to turn the Busso around 90 degress in a GTV 916 to make it RWD. Then either use a BMW box with adapter or somehow use the A bracket mounts of the 916 rear subframe to mount a custom suspension with the transaxle of either the GTV6 or a Porsche 944. But I'm not sure there is enough space in a 916 for a longitudinal Busso.

Converting a 916 to RWD: anything is possible but you'd have to make substantial modifications to the monocoque structure, this would technically make it fail to meet the DVLA points rule for retaining the original vehicle identity and if reported to DVLA either by your MOT tester or a roadside police stop, they would withdraw the V5 and you'd be in a world of pain having to get it through a BIVA test like a kit car.

Fair enough. What about moving the engine to the back, behind the seats? Quite a bit less work I would think?
No point to be honest, not enough space at back of GTV and would be mother of all projects , cost and engineering wise. From the same era, people have done 4x4 conversions ot the Alfa 155 but then had to completely change the floor as the 155Q4 (factory 4x4 using lancia Integrale engine, 4x4 etc) has a different floor to accommodate propshaft, rear diff etc which is why there is no spare wheel well in boot.
Putting the Busso V6 longitudinally has been done in a Alfa 105 coupe several times.
Hrrrm not really, all Tipo cars share the same floor, prop-tunnel etc. Even the mounting points. The difference is tank position etc, thats why everyone in Fiat Coupe's using the 155Q4 (or Dedra Integrale or Tempra 4x4) drivetrain have to use that smaller petrol tank.
(Also of course, the long 5-cyl lump is an issue with the 4wd gearbox, the Coupe 16VT is an easier starting point. Nothing's impossible tho)

Maybe easier - would be similar to the sprint further up the page. But you still have the same problem if DVLA ever find out as you’d definitely have to modify the monocoque. That sprint was probably done >20 years ago. I don’t know when the points system was introduced.
I’ve got a Busso in my Scimitar, but the chassis is unmodified so it’s ok.
