Installing quattro system in to FWD A4 B5, possible ??

[jmicaelk]

Hi guys, I know this might be hard to impossible, but what would it take body vise to make this work. Quattro system in to a FWD body. Someone told me they were different so how much work is required to make it work, I guess it is the tunnel that is not big enough and no place for rear diff. Please anyone help me out as I missed out on the only quattro for sale here in Thai for the last year or so :(

Gee, if there is only 1 quattro A4 rolling around, I wouldn't want one. That guy is going to have a tough time finding quattro-specific parts - like rear brake rotors. It would be best if you stick with the more common variety.

But to answer your question, anything is possible. No, it doesn't bolt in - the unibody is different. It would be some pretty serious fabrication. Basically, if you are a good enough fabricator to make your own car trailer from scratch, so you can drag your utterly broken audi around from place to place, you could probably handle the fabrication involved with attaching the quattro bits to a FWD model. Key words being utterly broken.

You'd have to weld in a new floor pan (from a quattro, as well as some inner structure). So although it's technically possible it would be stupid to do so. Just buy a quattro car.

[jmicaelk]

It is not the only one here, just the only one sold in the last year, people who have them won't sell them.
Parts i would have to get from US or Europe and some from Japan or Australia, they bring in cut cars from Japan all the time, so parts will not be so much of a problem, but the car itself is

I know, not the easiest thing to do, and not stupid if it is the only thing you can do, I will buy a quattro if I can find one more, but i found a broken down car for about $1300 and that is cheap here, so I want to see what I can do with it. I better find out if i can get the body panels that I need and see what to remove, skilled workers are plenty and cheap. So lets see what to do if I don't find one more, but the info is not good :(

Thanks Micael

Do you live around hills? If not I wouldn't worry too much about getting a quattro system. I live around flat surfaces and no hills plus I never see snow and I'm doing fine!

[jmicaelk]

No, but I am planing for a lot of HP, so FWD and 500+ hp is not so much fun. What is the level before you guys think quattro is needed ??

[Concker]

I totally agree to get Quattro if your going 500+
as for for when its needed.. well if your planning to use it on a track etc the quattro is 10times the fun to drive regardless of the horsepower..

But then again i live in Norway with plently of snow... so for for me every Audi's should be quattro's

And yeah its possible to convert a FWD to a quattro with tons and tons of work.. so its never going to be worth it..
should rather just keep looking for a quattro that is in decent shape and build on that... if they are that hard to get in the us im guessing you could try to import one maybe?

[BrucexL33]

gdamn! While you're at it, what mods are you planning to do?

[nynoah]

Buy a crap car and wait for a good audi to come by. If they are so rare over there, I would be looking at all body styles of Audi quattros, to include the older ones or newer. Modding 1990s coupe/S2 is pretty rewarding too.

don't hate the FWD lol

not worth the time to convert, like these guys say....but I have plenty of fun in my FWD a4 and I love how people hate it =)

[pac1085]

it would probably be cheaper to import one somehow, than to do a quattro conversion

[nynoah]

WOW... Thailand sucks for cars. WTF? Must be some real corruption going on there.

Best advice just find any car you can that is quattro and think of it as a base to swap into. Buy a cut car from Japan and go to town. Heck you could find a coupe, or an 80 .... or what ever. Just make a car if you are so inclined. I built an 85 VW golf II VR6 while I was stationed in Germany.

Try MotorGeek, many people claim on that site that everything bolts right in and people have claimed they have done it without welding anything. I have never done it and said it could not be done but they corrected me so it may be possible. If anyone in thread has actually tried and found it won't work please let us know otherwise it may be possible.

[nynoah]

I second www.motorgeek.com Those guys put other modding to shame. They are nuts and know all.

[Scotty@Advanced]

There is some confusion.. The B5 rear floor pans and inner structures are very different from one another, so you cannot bolt in a quattro drivetrain to a FWD body FOR THE B5. However for the B6 I've heard that the body is the same between FWD and AWD.

To convert a B5 to quattro you will need:

Rear trunk pan
Side inner panels
Front floor pan
Fuel tank with filler neck
Rear subframe
Rear suspension with differential
Transmission
Transmission tunnel
Brake lines
Propeller shaft

Interesting, I guess you would know for sure. They must have mixed the B5 with the B6 if you say it won't work easily.

[nynoah]

No the quattro system (rear) and suspension between the b5 and the B6 are very different.

I understand that. To make it more clear, the people on Motorgeek who claimed you could make a B5 A4 FWD car into an AWD car by just moving parts over must have been mistaken and confused this with making a B6 A4 FWD car into an AWD car.

they must have. the cars are more different than they must think. plenty of things are FWD/AWD specific

[jmicaelk]

Well I will be keep looking, but if I don't find then i have no choice, this car is too cheap for thailand to pass up on, but the tranny don't shift and engine won't start, but I wasn't planing on keeping either so it is ok
But if i have to do all the body work I have plenty of good welders to use, so it would be possible, just need to see all the parts and get them here

[jmicaelk]

This is Thailand with 314% tax on cars, and they don't count on the price I paid for the car, but the book value. I could build my own car cheaper :(

[jmicaelk]

gdamn! While you're at it, what mods are you planning to do?

2.7T engine or 4.2 V8. After that i will be back to building my 350Z widebody again :)

[jmicaelk]

So how much HP can or should I drive safely on a FWD A4, some say up to 350 hp, is that crank or whp ??
I have sourced a 1.8T to swap in, but have to see about that as the car is a 2.4 V6, need a lot of cables for that swap I guess.

When you say safely, do you mean without the engine blowing up or so that you don't lose control of the car? From my research, I believe the potential HP is the same as the quattro.

Not blowing up, that should be the same, but when too much power to front wheels and steering, it will not be safe

There's a lot of variables and can be answered differently based on the platform such as track, street, hills, snow etc. AWD will always be the safest! But there isn't a lot of downsides to FWD if you know how to control it i.e when to brake, how fast you should enter corners etc. FWD experience understeer when going super fast (not turning when the driver wants to turn!).

I have seen some people saying that if over 350 hp, then i should not drive it on a FWD, but is it whp or crank, big differences

I believe that could be true for a FWD with 350 to the wheels. But it can still be done. A fellow audiziner who just posted earlier GabeRossi built an incredible FWD that i've been following :
http://www.audizine.com/forum/showth...s-Build-Thread

Im not exactly sure how much HP he's putting down but you can tell from his build its a beast!

Thanks, reading up on your thread now :) great work, maybe I build something on the FWD first, not as extreme, but at least I get to learn the platform and have time to find the quattro

[redline380]

I gotta ask, do you just have a shit ton of money to burn or something?

Thanks, there is a lot of love put into my build ;) my power goal is over 550fwhp..very achievable once I put IE race cams in, and get my intake mani...

As far as being controllable with a ton of HP to the front wheels, its not bad at all. Unlike the Transverse 1.8t guys our Longitudinal setup prevents the serious torque steer that you get with the transverse setup. 1-3rd gear in my car is spinning but i'm not wandering all over the road, i'm just laying down strips of rubber until I hook. As far as cornering the car feels very balanced for a FWD car. Obviously Quattro would handle much better, but the FWD is still not a slouch.

haha finally some help defending the FWD! I did my best for a few posts then I had to bring out the big guns and show him your build.

Well not really, but I just sold my 350Z and they cost about 50,000 USD here, I can get this -99 A4 that doesn't run for $1,300 so there will be a few dollar left for fun things. I plan to bring Audi cars and parts in to my business as well so what I learn and develop I can use in my business as well, so could be a win win for me, at least I get a cool car :)
