88 Quattro - Lehmann edition

OK, so I entered the gang of old turbocharged typ 85 owners this autumn. To avoid cluttering up the urquattro picture thread, I thought I'd do some small thread for the car itself here. Nothing major changes will be done though...

The car itself is originally a 1988 Quattro from Switzerland, and holds the downgraded WX engine at 162~165 hp, black leather interior, Steingrau color. Originally... :laugh:

At some point, a previous German owner sent the car to Lehmann Motorentechnik. If you don't know Lehmann, the hints are that Lehmann is (the?) Audi Sport engine provider, also valid back in the days of Röhrl and the rest. Here they built the engine into a 2.2L and featuring some Group A (and B) parts, and general Lehmann work at the head. Nothing over the top here, as the original CIS is still in place, but the fun of it combined with my dedicated interest in the old Audi rallyes made it an easy choice. Also being non-EU, actually picking this up was a nice deal compared to importing a similar specimen from Germany or Switzerland.

So what were the downsides?
On an old lady like this, there are always some bits and pieces not up to standards. The car is resprayed, but OK, it is not 100% original either with the Lehmann work done. The antenna doesn't go all the way. The amber turns were swapped for repro white ones, and the previous owner did the classic mistake of mounting bigger speakers, and the Polk items looks horrible! The Ronals were swapped for Compomotives in OEM-dimension, as "they're the ones used on the rally cars". The whole idea he had of these cars were just so silly for a urq/sq lover as myself. At that note, he also fitted EBC yellow(?)stuff pads that are sh!t on normal road use, and the handbrake cables are worn/stretched. Luckily, I am sourcing parts as a badger in may!



Is that a custom ordered plate provided by your vehicle registration department?
If not, are you able to run a replica plate on the front of your car? In the States, and Canada, certain areas allow for this.
In Norway the first letters in the road legal plates are related to areas the car is registered. Unlike in Germany, these stay with the car throught its lifespan, and they are selectable. Funnily enough, the previous owner resided in that area where they have "UR" - a desired option for imported urquattros all over the country. So the IN-LA 22 plates are showplates, you are not allowed to utilize these at all on the road, as one can be faced with falsification charges.





Future plans?
Yes... First of all I want to find all the tiny hard to find bits to get it going in a look I like. Amber turns are sourced and bought, the same a NOS Votex antenna, handbrake cables and other bits. I did borrow a center shaft from an Audi A4 quattro Supertouring, and did measure it to see if it is applicable with the 016 urquattro drivetrain. No idea so far...but the shaft weighet 4100 grams with its carbon weave/titanium construction.



From a friendship, where I somewhat supported with details in the restoration of two old rallye Quattros and a finished rallye Sport Quattro, I hope to get some input on the rallycar shafts. Also on its way from Germany are some Die Wethje parts.

If the CIS goes, I think I'll do a 300hp "Gr A" Motronic...
Thanks for tuning in!

Thanks guys.
The whole thing is that the urquattro is an ICON. When people messes it up with alterations not thought through, it is simply bugging me. Luckily, they are more or less reversable. :facepalm:

I like the looks of it, but getting the amber turns on in front did a whole lot. The picture of the grey one in The picture thread totally convinced me of that. Here are some detail shots, inclusive the almost-same-nyance-Compomotives from when I picked it up in October.









Picked up a new expansion tank today at the dealer, got new handbrake wires, and other bits and pieces already aquired.
Uhm yeah, also having the rallye inlet parts on its way... :laugh:

Thanks guys.

The compomotives might be sold, or kept for some playful winterrubber (icespikeeds or studded ones perhaps?).
I am looking into rallye bits, unsure what to seek for. Just collecting them has some value...
This car would look killer on the metal finish works Fuchs wheels! :thumbup:

Nothing new in particular with the car itself, just charging the battery a bit by driving on fresh powder snow gently around neighboring streets.
But I have aquired some parts, and I am really looking forward to sorting out the horrible brakes and mounting a functioning NOS Votex antenna.
Swapping for a white expansion tank could brush up the enginebay aswell! :laugh:



After the feedback I got on the engine, I have moderated my plans for it consideratly.
On a general basis, I suspect this engine to be quite like the 2.1L 238hp one in the 1987 Audi 200 Group A car, without knowing for sure ofcourse.
But it was too late for parts on its way. Anybody recognizing this part?

No suggestions on the part above? :laugh:

Either way, it seems the Trans Am has the basic Bosch unit for boost, so I think I'll get the uprated 2.7T / 225hp 1.8T unit into mine aswell, instead of the nasty Samco one.

I assume the "teardrop" hos of 034 fits all 10VT engines?

I also experienced flooring the brake pedal, shortly followed by a locking passenger side calipper.
The car now resides at VW/Audi, where some elderly VW mechanic (with own urquattro) mends it.
Seems like one cracked brakehose up front, two bulgeing ones at the rear, and a pipe in dire ned of change.

Been searching for OEM turnsignales for a long while, but I gave in and ordered a set of repros of eBay.
Anybody else in here have tried these? I am tired of the whites with amber up front.

Got news from the workshop that the brake regulating valve (??) had rusted and was not able to be mended. Autohaus AZ and 034 came up as suppliers, so I opted for 034 as they also have the black silicone inlet-hose, and purchased the brake accumulator and some NGK sparks aswell.

Only thing though, is that 034 doesn't stock the OE parts, so dashing out $200+ for UPS doesn't pay of that much. :thumbdown:
Great selection and fast response on email/feedback though, but they could've mentioned about the OE parts somewhere - after all I am suppose to get this half way across the globe!

Had a lucky find on eBay aswell, as a pair of the higher-level Polk Audio 6x9 speaker mesh was available for $18 for a pair. PO naturally had the stereo specialist cut into the metal works of the over the trunk, so it is time to clean up the sh!tty looking ones I have and get the shelf lookin all-black, and avoid any further adaption to other 6x9s. :thumbup:

Out shooting today... :thumbup:



As I got the IMSA crankshaft, I am thinking about building a sort of Sport Quattro engine.
Basis would be 2190cm² in normal cast-iron block, standard head and KW style exhaust manifold (if not getting a Wagner for K24/26 flange). Theoretically limited at 8500 rpms.

No big news actually, but I'm getting a Sport Quattro turbo to match with the original exhaust manifold.
Will try to get some ideas of figures from James B, but I believe this is capable of 450hp on 1.3BARg.
But look at the graphs anno 1983, my Lehmann 10V has more torque, and it drops at top rpm - how will this be on a valver? Don't know, but the K27 turbo is according to rallye documentations atleast.

James (Fusilier) has such a great writeup on the old style KKKs on his homepage, so I will not elaborate further over this. The thing I can say however is that I am a bit puzzled that the in-port of the K26/24-7200 RS2 unit has a straigh inlet port, whereas this K27 has a coned one from approx 62 to 46mm.

Note how the backplate also has the K28 numbers. Sadly no idea what these represent though.

I believe a lot of spares are for sale, as they also purchased some S2000 cars for more fun-activities.

Not sure on pictures gone missing, or if I just forgot to present the ones we shot for the magazine.
So here goes!








edit: look how aweful those speakers look! 1. pri to change them out with something more descrete.
Been thinking of Infinity 693.11 or what they're called, a bit of oldskool plastics look.

Purchases Samco induction kit, but it's not to my taste with black/red brick color combination.
eBay add even stated available in brick red only, so there's a hot tip for you!
