1990 Audi Coupe Quattro S2 replica

For a long time now, one of the most popular builds that Audi fans have undertaken is coupling the excellent 20 valve turbocharged inline-5 Audi motor to the capable, fun and good looking Coupe Quattro. It makes sense; out of the box, the heavy Type 89 chassis had a hard time feeling fast despite being equipped with the fantastic 7A 20 valve motor. Consequently, both the non-turbo motor and the Coupe got a undeserved reputation as being slow compared to the competition. However, just as the 4000 Quattro was a stout chassis in search of more power, adding the AAN 20 valve turbo to the Coupe Quattro was a match made in heaven – certainly, the factory agreed, since that was basically what they did to create the S2. This particular conversion goes to 11, upgrading the engine, swapping in a TDi-spec 6 speed and all the correct S2/RS2 bits to make a stunning looker with even more stunning performance:

The modifications and work done on this car is well documented. The car is fast and runs flawlessly. Pretty much everything has been cleaned, maintained, refreshed, upgraded, fixed and works. Interior was removed. Carpet shampooed. All interior bulbs were replaced, even the ones that were soldered. Even the underhood light bulb works.

I have over $20k into the car. Email me (ktnguye1@gmail.com) with any questions or for my contact info if you are interested.

Reading through the build list on this car, it’s easy to see the claimed $20,000 invested; indeed, I bet if I started to add up the details on my car I’d come up with somewhere around that figure too. The question is, does that make the car worth $18,000? Well, that’s a bit harder to justify – especially when you consider that there recently was a real factory S2 for sale in Canada for $10,000. I have to believe that over the next two years, the market price on these built S2 replicas is going to crumble as real cars make their way over since you can pick up a pretty good example for the equivalent of $5,000 – $6,000 in Europe.

However, about this car; it’s pretty awesome, it’s undoubtedly fast, it looks fantastic – there’s a lot to like here! I really like the incorporation of the correct S2 front end rather than the commonplace RS2 “catfish” bumper cover which often looks out of place. For me though, despite the great condition and quite impressive build sheet, I’m just not sure it’s worth $18,000. For that price, I’d really rather have very nice 944 Turbo or 968 in all honesty, but if the S2 is your goal, perhaps this strikes your fancy.

    Mods to a car follow the rule of diminishing returns….unfortunately…
    You have to find the right a$$ for the right seat….someone who views the car and says THATS how i would build mine….and then pay you for the luxury of it being turnkey…
    otherwise don’t get expect to get a return on the mods….
    up to date maintenance with service records, using OEM parts, now those things add value to a car IMHO

    IMHO this car is tasteful, fast, well executed, and makes a WRX look like a toaster oven. Looks to be a detailed OEM+ conversion with all the best proven upgrades and just the right amount of aggression.

    As a former CQ owner and S2 lover, I’ll be waiting to bring a real one over for less $$ than this swap.

    MDriver, while I don’t disagree in general on modified cars, I think overall I agree with UrSDriver – this is a pretty well executed OEM-sourced conversion. However, like you and Poorhouse agree, I don’t think it justifies the price, unfortunately for the seller.

    There is a very well-done Coupe Quattro RS2 conversion around these parts, all black on late-model A4 wheels that looks the business. Guy probably spent a kidney on it. I would love to drive it, but have to agree that waiting a few years to import a real one is the pragmatic choice.
