1.8t in 5 pot quattro
 

apologies for the possible sacriledge.....

been reading up on this in a few places (and bothering people for help), used the search etc. I already have a spec'd AEB which is why I'm looking for a coupe quattro but can't find anyone over here who has got one up and running in a B3 or B4. Would be great to get some concrete info on it, while I understand that the 5 pot 'boxes have multi fit bellhousings for 4 and 5 pot engines, I have read that the input shaft from the 'box is too long for the 1.8t.....on a total tangent I have read that some of the V6 bellhousings are a suitable pattern for 1.8t fitment!!

Can anyone please give some solid info?:cryin:

I haven't forgotten, on the case as I type. Waiting for a reply from I guy in the states who's got an agu 18t in his cq sprintcar
speak soon mate

No worries Gav, figured I had nagged you enough so was happily nosing about while waiting.;)

5 cylinderand 4 cylinder quattro boxes have different bellhousings..... Not a multifitment sadly.

A type89 4cylinder quattro is what you'd need.

So is it the non quattro boxes that are dual fitment bellhousing....or stateside equipment only?

I promise I'm not making it up....5th post down if I am not misreading correctly.

No Idea what the yanks got but i can guarentee a 4cylinder bellhousing differs from a 5cylinder by a bit... I have both here, a 4cylinder 016 quattro box and enough 5 cylinders to run a rally team!

I dont think audi has ever made a mulitfitment box.... It doesnt seem logical from a manufacturer perspective.

I guess it must be stateside then - even got an email from one of the stateside audi nuts stating that '88 on boxes are dual fitment. Gutted.

4 pot quattro's seem to be even more difficult to get hold of.

Ok then, one for ya......will a four pot quattro 'box bolt straight up in place of a 5 pot one?

If its an 016 or 01e ( i think for typ89) then yes.... modern quattro is actually haldex and different layout (sorry if you know this just clarifying the points incase)....

Something like an audi 80 Quattro or coupe quattro with a 16v will have right box but very hard to come by as you say.... I'm not sure on condition of my 4 cylinder gearbox otherwise i'd be happy to sell it on...

I have swapped all gearsets with CQ typ85 ones (the bellhousing casing is different but the gearset casings are identical.) If your really struggling i'll give mine a clean and an inspect for you :)

Only the transverse mounted 'boxes are Haldex (that's the rear diff), the longitudibnal ones still use mechnaical Torsen system. A quattro box from an A4 quattro (5 or 6speed available) would be a good plan as only mod req'd would be possible minor fiddling with the mounts.
May need to check on compatibilty of gear ratios with existing rear diff but that's not too dificult to check.
Should make a nice car, the 1.8T is a very tunebale engine and very light.
I ADORE the 5-pots but the 1.8T would make a very good sensible choice for a rapid 80! SHorter, lighter and more powerful.... Keep us updated!

I got this answer on audifans

going by our buddies over in motorgeek land you CANNOT bolt a 4 cyl to the 016 box properly,although they do say theres a european version with the 4 bolt pattern(poss mean rare in the usa?). a 4 cyl needs a 01a or 01e they say:confused::confused:

i've sucessfully bolted a ng 5 pot in a b3 16v quattros gearbox. a 10v turbo onto a b4 16v quattro gearbox and the latest conversion a 1.8t onto a b3 90 quattro gearbox :tup: nothing needed other than bolts lol

There is a few 5 pot-1.8t swaps on motorgeek, as far as I can remember 01a boxes will bolt up to 4/5 cylinders, 01e boxes will also bolt up to both, ie b3/b4 series 3 coupes. 016 boxes are either 4 or 5 cylinder specific.

Think sam has proved that you can swap engines around on the 01a!

WTF? Quattros with transverse engines are haldex.

I wouldn't want to give up 'my' 5 pot heaven, but I still would love to see a type-85 Coupe quattro with a 1.8T and 300bhp. :D

I'd love to see how it goes, & handles. :tup: :devil:

it definately fits ;)

Sam, that is awesome:arf: (if the photo quality is a bit poop:razz:). Finally got the MOT on mine so I will be driving it about while I gather up the rest of what I need for the conversion.

Is there a definative answer on this? Some say yes some say no! :wall:

Thinking of 5 cylinder type 89 coupe quattro. And then fitting a 4 cylinder 20 vavle turbo in it

just noticed this post, 4 cylinder 20v turbo definately DOES FIT on type 89 cq gearbox :tup:

Indeed it does! And with an A4 clutch/flywheel it all works.

16 valve passenger mount fits perfect, and in the right place. 16 valve snub mount and cross bar fits and in the right place with a bit of modding to avoid one of the bosses. Made a new drivers side mount to fit it all in the right place.

Now just to plumb it in and sort out the wiring!!

John

Im putting a 1.8t into my 16v coupe (non quattro) Got an engine and some other bits, still collecting. Any bits of info you guys have would be much apreciated.

Sam if you have some more info on this swap and engine mounts and clutches etc that would be really useful. And pics too!

:) cheers, Jim

pretty much exactly what jds says. i have yet to drive it but im 100% confident that the a4 clutch is going to work fine, im not using standard turbo so im not sure wether the a4 downpipe will fit.
i will get some better pics took hopefully this weekend, but 2nd baby is due on friday so may have to put it off..... for a few hours at least :D
the water outlet on the back of the head was the only thing that needed modding to fit other than snub mount and fan, i got a flange cut from alloy and pipes made etc just to realise theres an easier way lol 25mm hole saw over the end of the pipe that points at the steerig rack, as far as you can go before you hit the main water pipe, snap off the outer bit your left with and then shorten it with a hacksaw so that when the suspension is fully compressed the steering arm wont hit the water pipe.
it looks just like this lol

snub mount is obvious what needs done when you try to bolt it to the motor and the i removed the fan from the aeb and took a grinder to the flange that holds it on and just used the twin fans from an 80, needed to remove some of the plastic so it didn't foul the automatic tensioner for the alternator belt etc.
got a video of it on my phone but cant get it off the dam thing, ive yet to wire the dash up(temp gauge, oil warning light etc) but it runs and revs perfectly. just need to redo the throttle cable and join the downpipe to the original. even got it on vagcom and there was a few codes up but just things that im not using,

Thanks sam thats great info. How did you sort your engine mounts. As the post above says, one fits spot on but the other needed making. I herd a cabriolet one from a 1.8 can be used?

The fan set up is one thing i been looking at. Mine has twin fans, but these only come on when the water temp gets to a certain level, so i was toying with the idea of removing one and keeping the viscus setup. But thinking about it i dont thin the transverse mounted engines will run a viscus fan cus that would be daft , so keeping the twin fans may be a better option. This would also reduce noise and powerloss.

Let me know how you get on with yours and if the engine stays at a steady 90 degrees.

Cant wait to get stuck into mine :devil:

Don't forget that there are two types of 20 valve. Transverse as used in Golfs, A3's etc and longditudonal as used in early Passat, A4's. Same head, different blocks.

I have used one from an A4, as its easier to fit in, but a bit more difficult to mod.

Thanks jds, i am using an AEB from an A4, went this rout for the same reasons as you. Would like to get about 230 hp (possibly a little more). Not entirely sure on the best way to do this on my budget (not much lol). It needs a new turbo anyway, just which one ?

i went for an aeb too, a remap on a standard turbo should just about manage that, but that would be the tiny k03 on its limits. im running a t28 off a 200sx and im hoping for 280bhp ish lol

engine mounts wise i modified an adr(1.8 20v non turbo) mount from an a6(the 100 shape 1) for the turbo side and used a b4 2l passenger mount.

and yeah golfs etc jut use electric fan. and they dont overheat, twin fans will be fine :D
