B7 rwd automatic to quattro automatic swap....

[Pegleg]

I have a 2008 audi a4 fwd automatic and I am look to get together a full parts list need to perform a quattro swap. I am sticking with the automatic trans because I have a full prosthetic leg on my right side... I have located a parts car a someone willing to ship me everything just want to make sure I don't miss anything. Thanks for the help in advance.

didnt Vizi do this?

[saizero]

Vizi's FWD-to-AWD-Conversion

[Pegleg]

It has been done manual swap just wondering what else is need as far as electronics.... like is tcm and just the engine harness is all that I need to add?

But the FWD Automatic is a CVT and wont work with Quattro. I assume you're picking up a 09L 6-speed Tiptronic with that parts car right?

You'll probably need a Tiptronic TCU and you'll need to recode your ECU to Quattro and Tiptronic. Don't think you'll need to modify/replace wiring, but I could be wrong...

Yes I'm picking up the trans as well

You'll need a new downpipe as well

And a new gas tank. you will lose 2 gallons of tank capacity.

Minor detail, haha.

Indeed

If you end up doing this could you make a build thread? I've been interested in this because I have more money into my 2008 then I can sell it for and made the mistake of not buying a Quattro.

Would the Quattro trans bolt up just fine? I can't find much info on it. I've read through Vizis thread but I believe it was manual to manual correct?

Yes I believe viz's was a manual to manual... I planed on doing a build thread as well

Awesome, keep us updated then man. I have a guy whose willing to trade me all the parts I need for the ones I take off and I'll pull the trigger and do it once I figure out more about the trans

Ok everyone I finally got my money back because the guy never shipped the parts.... them my car breaks down its going to be awhile before 8 can do the build.... just my luck get stuck dealing with shady mofos

Are they shaped differently ?

Cannot fine a picture of downpipe for FWD for the life of me

I believe the quattro one in longer for clearance purposes

I've just finished doing the swap from cvt to quattro automatic. You need all the parts from the quattro, including the engine. You also need the bracket from the quattro to hang propeller shaft in the car mid section. I'm stuck with the fuel gauge reading now, always full. Other than that, everything is good

[Pegleg]

Why the engine also? They should be the same motors?

The cvt/manual have a different crankshaft than the Tiptronic.

[aams]

True as what charles.waite mentioned

Why has this never been said before in all the conversion threads? Facepalm.

Can't you just change out the crankshaft?

Theoritically you can, but i don't know what else involve in doing so

[Charles.waite]

Of course you can. The only difference is the space for the needle bearing. The thing is, you have to pull the engine and completely disassemble it To remove the crankshaft. It's 10000x easier to get a different engine.

Also there is no "Quattro" transmission. Do you mean Tiptronic?

[aams]

Yes, tiptronic.

Any updates?

[Okedokey]

I wonder if you could get a mating plate?

[aluthman]

Wouldn't help. The tiptronic crank isn't machined to accept a pilot bearing which is needed to work with a manual transmission.

But that crank still mates up to the CVT... which doesn't have the pilot bearing...

[aluthman]

Manual and cvt cranks are the same and will also bolt to a tiptronic transmission. Tiptronic cranks will accept the manual flywheel but not the pilot bearing.

This.

[Forge04]

Okay, so let me see if I understand this:

A Tiptronic engine will not allow a CVT/manual to bolt up?

A CVT/manual engine will allow a Tiptronic transmission to bolt up?

Because that's what I gathered from this recent activity, however, this post contradicts this:

I've just finished doing the swap from cvt to quattro automatic. You need all the parts from the quattro, including the engine. You also need the bracket from the quattro to hang propeller shaft in the car mid section. I'm stuck with the fuel gauge reading now, always full. Other than that, everything is good

So can there be a consensus? I ask because I have the CVT and would love to save up and go Quattro...

[Charles.waite]

Look up b5/6 Quattro swaps. It's the same deal.

Your posted understanding is correct. The post you quoted is the bolded scenario. You don't need the engine, not sure why they said that.

[Forge04]

But you can see the concern right?!

Imagine spending all the time and effort to get the rear axle assembly, the gas tank, the driveshaft, and the electrical brain/wiring because at this point, lawl, who the hell knows exactly what one would need... only to find out that, sheeeeet, I need the whole engine too!

And especially if aams just got done swapping... I've seen before where how it should work and how it actually works are two different things.

Bump👉
As for cvt/ manual to tiptronic (fwd, yes same as old Passats) or FWD conversion you DON'T have to swap motor. Yes, cranks are different, but What I did, I did extensive research about bushings and find out that Dorman brand has bushings slightly oversized but it WILL work with crankshaft and torque converter after slightly "dremeling" around the cranshaft and sending down torque converter tip. Than I used starter plate from tiptronic and it's all fit like a charm. My question is, as I never dealt with vag before ( could not find anybody in Oregon to do so either) does it need to be coded after swaps regarding ECM, TCU (I'm assuming swapping TCUs it's given) or any other components? Sorry I'm a good mech but not a millennial 😁
