Audi 4000 Q with 5cyl TD motor--Anybody done This?

[AudiVWguy]

I was thinking about this the other day, what if you took an 87 4000 with Quattro, took out the gasser and built a 5cyl Turbo Diesel motor it. I don't know much about the Audi Diesels. So what kind of horse power and torque could these motors be good for? :twisted:  I heard the car weighs about 2800lbs.
You guys know anybody who's done this?

Don´t know if anybody has done yet, but you could ask it again in a couple of months :wink:

the 4k's are really nice cars.  with quattro, it is a good platform for a rally car  :twisted:

you could always install a 4 cylinder diesel engine.  the 5 cylinders are good, but IMO, a 1.9TD or even 1.9TDI would be a better idea.  there just isn't the same parts availability for the 5 cyl diesel engine...

over in Europe the 4k came with a 4 cylinder engine.  the block should bolt right up to the trans as well, and buy the right brackets, or even just make your own.

Below is the 5 cylinder power graph:


it is actually just a 1.6 motor with an extra cylinder on it.

here is the 1.6 motor:


so as you can see, the power increase is almost relative to the extra cylinder.  going the 1.9 route with some mods should easily beat the stock 5 cyl, but a modded 5 cyl could still do quite well.  the main problem is having to buy an extra 2 head studs, valves, seals, etc.  but at least the 2.4L diesel's metal head gasket will work on the 2.0TD 5 cyl engine.

My quattro is actually 4-cylinder 1,8 carb engined. I have a good 1,6TD lying at floor, removed from ´86 fwd 80. It is pretty tempting to install the 1,6 to quattro I also have 5cyl 2,4TD in garage that I´d like to use. 2,5TDI would be cool too But there are several differences in 4- and 5-cylinder bodies. Subframe, engine mounts, transmission, rear differential etc... 4-cyl engine does not bolt to typ81/85 5-cyl transmission. Later trannys have both bolt patterns.

ah thats good to know about the proper years that bolt up to the 4 cyl blocks.  i was considering the swap on an '87 audi 4k.  if it was quattro, it would have been a done deal, but i'm still lingering... holding out for a quattro version  :lol:

of course adapter plates could make the swap work, but all that custom work would make it $$$$$

Where can I find a metal Headgasket for a 5 cylinder diesel?

i did this conversion already, giles pump dnosd308 injectors 6,500rpm govnr mod 35lbs boost, it still to this day the fastest car i own, it even beats my volvo 760td with twin turbos, the volvo uses the 6 cylinder version of the audi turbo diesel, the 5 cylinder has some wicked power band and nothing else comes close to it.
