want to convert my mk1 caddy to rwd would like to use a a vag engine & gearbox but which one???
i have a 1.8T here at the house would be ideal to use this

I dont think you will get a vag box for the job but what you will get is a load of shite talk about using a 4 motion box
without the front shafts.
without the front shafts.
you can use a toyota supra or nissan silvia rwd gearbox using an adaptor plate .
have a read of this. tdi but the adapter kit is for a 1.8t also.

its a bit too much messing and expense i'd much prefer to go with a tried and tested method
think ill get a redtop and manta/omega/escort gearbox to fit and either an e30 diff or escort axle which do ya think?
the prop will be costom made to fit

I wonder how would a longitudinally mounted 20v engine and gearbox from a passat or similar work. Mount the gearbox and engine in the back with the outputs from the gearbox right between the rear wheels. So a mid engine type set up basically. Make up your own wishbones for a double wish bone suspension set up. Make up a frame to mount support the engine and gearbox and the suspension. Weld/bolt the whole lot to the caddy chassis. Lots of custom work, would be cool if you pulled it off.
Problems would be the gear linkage and getting it to work. I think everything else is do-able..ish..!
I wouldn't do this to a really good caddy, maybe one with a rotten rear bed…
Any sort of rwd conversion will require lots of custom fabrication so it might be no harder or easier than using a escort rear axle..making up your own prop shaft…sticking in a red top engine and supra gearbox etc etc..either way there is lots of work.

no my budget isn't that big and its a little advanced for me to be honest
think ill go with an escort axle as i have one handy and will use a redtop and omega gearbox for now
if it works out and if i want to go with more power ill upgrade the system to 20v and supra gearbox and diff
where do i start mounting first engine or gearbox or will i just bolt both together and see how it goes?

Not having a dig, but its not a great sign having to ask questions like that if your on for a job of this magnitude..

Look up other difficult engine conversions and see what they did, you shouldn't tackle into this without having a very good idea of what your at..

i have a lot of research done on it
seen what people have used i just wanted to see if i could use a vag engine instead of using jap parts.
i know an escort axle will bolt straight on but will be insufficient if going for big power
i was going to use the mk2 escort type 9 gearbox but that will require a new bell housing so to keep it cheap ill get an omega one which will bolt on with no messing to a red top. as i havent seen a redtop in a caddy before im unaware of the dimensions of it and how far back of forward to mount im sure ill overcome this when its in the engine bay but i'd like to get an idea. dont worry about me doing this i have a lot of ideas in my head i just wanted someone else to give their two cents on this.
im in two minds about the steering rack
option 1
is to move it up above the gearbox and work it that way or
option 2
is mount it on a cross member and put the left hub on the right of the car and the right hub on the left hand side of the car this will mean the track rods will be at the front of the hubs not the back. the steering colum will be ectended to meet this.

The position of your gear stick will determine the position of the engine and box. You will have to cut the shit out of the
bulkhead and tunnel to fit it all in.
I'd fit a nice fwd motor in the caddy and buy a 325i for fun.

if i was doing what you are at i'd have the following on my list.
Saab 9000 2.3 turbo engine with a holset/schwitzer turbo attached (standard internals are forged and good for 350bhp)
Opel/vauxhall omega v6 manual box (bolts straight onto Saab engine (only available from the mv6 AFAIK)
Volvo 240/740 rear axle with an electronic Dana locker diff.
but firstly i'd do what Dave said and put a good vag fwd engine into the caddy and get yourself a nice rwd car and then go from there.

First off, bin the leaf springs. Leaf springs, rwd and 200hp plus will have a massive amount of wheel hop on a fast take off and will also probable twist the chassis/bed.
Id use and Audi 016 gearbox, chop off as much of the bellhousing as you want to clearance it under the rear bed, bolt a 944 torque tube to it, get a bellhousing off an 02A, tig weld a 15mm 6061 alloy plate to the rear of it, bolt that to the front end of torque tube, that will bolt to the 1.8T 058 or 06A block.
Hang the gear box under the bed on a simple 2 mount bracket. Use the Passat engine mounts to keep all the wind up torque the same from front to back. This way puts no stress through the already weak chassis, the torque tube will take 90% of it.
For the rear suspension you could bolt in a complete bmw rear subframe, or a 924/944 subframe only having just two handy mounting points at the front of wheel, two 8mm bolts(1 per side above wheel), and then you'll just have to mount the upper shock eyes.
The gear levers position can also be moved anywhere along the torque tube by adding to or cutting the single link bar to box.
The 016 gearbox is also fully independent then to any rear suspension subframe when fitted this way, great scope. All you need to is find the correct length drive shafts from X subframe hubs to your Audi box.
The gearbox and diff being in the rear will also help weight distribution an awful lot therefore making it handle better.
Putting the box in the rear will also mean you wont have to butcher the bulkhead as much.
The 016 box in all its glory>

The above is how Id do it. It will also end up being all VAG then also, and do away with the leaf springs, and would end up very drivable.
Its pretty straight forward too. And even more-so taking into account your qualifications.

considering the work involved making a tunnel in floor to make front engined RWD would you not consider mid mounting the 20vT and using Passat gearbox? Mount the whole subframe from passat/A4 in rear
You prob would have to modify steering angles to get handling 100% but still reckon be less work than front engined RWD

im not afraid if putting a tunnel in it its too too big of a job all things considered just a little thinking and not being careless with the grinder
looking at the torque tune it looks like it will fit without too much hassle or cutting
i like the that brian suggested weight distrubution would be very good, i dont like the look of a mid engine setup looks to lazy to be honest
i'd like to keep it suttle looking and still have some practical use for the bed.
the bed will be braced as well as most of the car to keep it from twisting.

QUOTE (gti-ronan @ May 16 2010, 02:13 PM) <{POST_SNAPBACK}>does that have a hydraulic release beaing?
and what would i get this gearbox from?
No manual, the release bearing is in the belhousing up front, its a simple fork and could be modded into the 02A belhousing or bits taken from the 924 or 944 housing.
The box came in off the top of my head, the audi 100, 200, 5000, and the Porsche 924, the 944 had a slightly different ratio box and possibly alloy but that would do you too.
I have a spare 016 box here incl torque tube and belhousing if your interested.
Google 016 to be sure of models, there could be more.
