what power can caddy 4x4 rear axel /diff handle?

Post by caddymaxi500 »

hello,

i have a 500hp 1.8t engine in my seat leon.
because of my hobby (motorcycle stunt riding) i want a caddy maxi, and i want to put the 1.8t engine from my leon in the caddy.
it have already a 02q gearbox from a audi a3 1.8tfsi so i can put a 4x4 diff on this gearbox. (for 02q its bolt on)
so my question is can i put a 4x4 caddy rear axel on a FWD caddy without cutting and welding, and can it handle 500hp?
its a haldex controled axel, right?
are there problems with lowering with the 4x4?
I saw some people make a golf6 rear axel/suspension fit on a caddy, but is this necessary?

thanks

with kind regards Ralf

I'm not an expert or would even know the answers you require.
If I can make only one very small contribution is to perhaps try LLL parts site.
This way you can see all the associated parts you may require for this conversion.
You will be able to see what gearboxes you may need to fit, probably one with the rear diff transfer case.
You can also see what prop is required, rear diff and also the correct haldex controller needed.
Then when you have this, you can go to various vag tuners with these components to see what the maximum torque you would see with the drivetrain you require.
You now your vans build year so it will show you diagrams of these parts and fasteners for installation guide.
It's just going to probably take a lot of time sitting down and making notes of the parts and cross referencing them with Google.
Good luck with this conversion

There would be a torque limit that the rear diff would be able to handle before it suffers from unscheduled dissassembly.
I do not know how much it would be, but I am sure someone with more knowledge will help with info soon enough.

If I remever it correctly the Caddy 4Motion version has 320nm of torque so that's what the rear axle has to handle from factory. What that axle really can handle? There are companies specialized in these kind of axles so try to contact them or get a stronger one made for your built. Don't know how much torque your Leon engine can produce? Think it can be more, so the axle if it can hold it or not is the question. Now you will probably know why people use a donor car to swap the whole system over from a from factory faster passenger car, perhaps that's a better way to go for your built as well. No problems that way with lowering as well as passenger cars, like a Golf R or S3 RS3, are already lower as the caddy is. And that way you will have all the parts you need.
