Tuning potential of Audi 2.0 TD by GTiTDi on 19 Sep, 2012 17:40
-
I recently pulled a low miles Audi 5000 2.0 TD engine out of an otherwise junk car. I realize it is closely related to a 1.6TD except with an extra cylinder.
What I am wondering is will putting this engine in an '87 4000CS quattro be worthwhile? Will it be capable of producing enough power to make it a fun car? I know it isn't any TDI but I figure with a bit of head porting, a tweaked injection pump, an intercooler, manual boost controller, and bigger nozzles this engine could be somewhat powerful. Am I nuts? It seems that the K24 turbo that it comes with is sought after by 5000 turbo gasser people, and the one on my engine is mint. -

Power to weight isn't quite as good as my Volvo L6, but Quattro should make up for it.

No one else has any input on this endeavour? Either I am so bat *** crazy that no one dare comment, Or no one has anything else to add. Guess I am on my own?

Its not a widely tuned motor, this forum is mostly 1.6 and 1.9 engines.
POST A BUILD THREAD WHEN YOU FIGURE OUT WHAT YOU'RE DOING! I'm excited to hear about it! -

i think it can easily be made to go long quite nicely install a nice intercooler, exhaust, and a giles pump. the old audis could come with a 1.6td and everyone i know who has had one said it really ran nice and was a nice car, so 25% more displacement and the better manifolds stock, it should be a fun car in awd form.

what better cover than a type 1 hood?

FWIW... the 2.0L engines had oiling issues..
with 130k miles on it, its COMPLETELY POSSIBLE that its clear worn out like mine is.. -

I've only seen 2 D24Ts with under 200K, and they use the same oiling system on a bigger motor..

I think the oiling issues were more of a 2.4 D/TD 6-cyl phenomenon. I've never personally seen any gas or diesel 5 cylinder with wear issues related to oil starvation of the rear cylinders. For whatever reason, it seems the Achilles heel on the 2.0 engines is the head. It seems the swirl chambers have more issues than on the 1.6.
Yes, putting the 5-cyl TD in your 4KQ is definately a worthwhile endeavor. It's something I wish Audi would have done from the factory. Don't dis on it because it's not a TDI. TDIs are great, but that 2.0 will drive much more like a gas engine, especially as far a revability goes (which is one of the reasons why VW decided to go with IDI instead of TDI initially). It should run great coupled to that 016 tranny in your 4KQ.
And yes, the 2.0 is every bit as tunable as the 1.6 and more. Compared to the 1.6, it has larger intake valves, a better intake manifold, and a more robust block. Don't be fooled though. Even though it's only 25% more displacment than the 1.6, it will actually weigh about 50% more. Again, this is primarily because of the beefier block.
The engine you have there is 82 HP stock. In intercooled form (Canada only), the 2.0 TD put out 100 HP stock. I think 110-120HP is generally considered the limit for a mildly tuned 1.6, so a mildly tuned 2.0 ought to be in the 140-150 range.
I'm actually thinking about doing a 2.0 TD conversion into a 4K myself. (Still in the hunting/gathering stage.) Also, check out this thread http://www.vwdiesel.net/forum/index.php?topic=25252.0 to a 100Q TD conversion I did a couple of years ago. Basically the same engine as the 2.0TD, but with bigger bore/stroke. -

THIS is what I was looking to hear.

What are you looking for? The stock 4k is putting down what 110hp? Some good torque numbers with the quattro should be loads of fun regardless.

i think the TD5 is capable of better power numbers (for its displacement) than the 1.6..
these 5 bangers are TOUGH.. just make sure to change the oil in it..
as for the pump, they are pretty boring in stock form, but will turn almost 6000 on a stock governor.. -

I wonder if they were 10mm like the volvos?

blocks or pumps?
blocks no, they are 12mm
pumps, yes.. they are most definitely 10mm.
