In my recent “Gimmie Five” 10K Friday, I charted some of the developments of the venerable Audi powerplant. Though the Eurovan would continue using I-5s in some applications, ostensibly 1997 would see the end of the line for the original configuration with the discontinuation of the S6 even if it’s returned in spirit in the new 07k turbocharged 5 seen in the TTRS and RS3. Those cars are the successors of the original small turbocharged Audis; the Quattro and the S2 coupe and Avant, and while we briefly got the 10V Quattro, none of the later small turbocharged variants came to the U.S.. For enthusiasts that were unwilling to wait for either the new models to launch or the European models to become legally eligible for importation, a popular pursuit has been to recreate the turbocharged package in the small chassis. Adding the turbocharged motor in 20V form instantly transformed the B3 and B4 into performance machines, and with plenty of tunability in the package it was possible to create a really serious package. That tuning has been taken to another level by an entire generation of new electronic fuel injection management which exploits the longevity and stout construction of the inline-5 and makes absolute monsters. Sure, it was impressive that Audi produced versions that managed the best part of 1,000 horsepower in certain tune in the 1980s – but that, of course, was a major manufacturer with near unlimited budget. What’s more impressive is that small tuning firms subsequently have been able not only to match but to exceed those power levels, with companies like 034 Motorsport and Dahlback Racing making 1,100 – 1,200 plus horsepower variants on their own. Even though the B3 chassis is fairly heavy, if you can turn up that boost to high levels you’ve got yourself a rocketship – and this S2 replica certainly has the right ingredients for that recipe:
