1991 Audi 90 quattro 20V Turbo

Everyone talks a good game, but let’s be honest – few undertake the heavy lifting involved with a project car. I’ve certainly been guilty of it more than once, having had a Coupe GT racecar that I just couldn’t quite come up with the resources to get together. Then I was going to drop my spare Audi 4.2 V8 into a derelict 924 chassis that was kicking around. I still think that’s a good idea, but it has not occurred. And I’m not alone, judging by how often ‘project’ cars come up for sale.

One of the more prevalent dreams in the Audi swaps is to recreate what Europeans had the advantage of all along – 20V turbo power in the small chassis. While most take the Coupe Quattro route for their swap, some go the unusual route of choosing an 80 or 90 quattro. They’re not as popular for a few reasons – mostly, the sedan platform doesn’t look as neat to some, but another reason is that tire size is more limited on the sedan. But let’s not forget that Audi built about 300 S2 sedans themselves, so it’s not without precedent.

Today’s car has taken inspiration from that and done the heavy lifting for your project already. So is it the car for you?

The good? Well, the 20V is already slotted in place, it’s turned up with some popular mods, the brakes are upgraded, and there are a lot of other fairly desirable parts done. The bad? To me, the result looks a little sloppy, if I’m honest. Perhaps its the matte black wrap that’s undoing the package for me, but that front end just doesn’t work – and it certainly doesn’t help that it’s poorly aligned and zip-tied together. I also partially get why people go gaga over the RS2-look bumpers, but to me the regular S2 sedan front end looks waaaayyyyyyy better. So, too, do the correct Speedline Avus wheels, though admittedly sourcing the European-market S8 wheels is pretty difficult.

I’m probably being too harsh, but then this car isn’t exactly cheap. So far, bids have hit $6,800. And you’d be right in saying ‘sure, but it’s a lot of car for that money’. But personally, I think I’d really rather have a clean stock and original 20V sedan sans turbo.

  1. “…Straight rust free body…” I don’t think that means what the seller thinks that means.

  2. Had a 200 20v, 90CSQ, UrS4. Always wanted to build this. Audi’s NLA parts supply makes it a non-starter….
