Not Your Dad's S4

Not Your Dad's S4

You ever just...... yeah, us too. 

Definitely not a car you see every day, let alone ever really. Come on, a factory 6spd manual Nogaro "slick-top" b5 s4... Let's cut to the chase and just get into it.

Well, it started when Mike bought this car as the infamous "Ken Stevens' 034 Motorsports Audi S4". The car came into our shop pretty unhealthy and needing a bit of TLC, but aside from the critical maintenance, Mike was about to start a journey on getting this to exactly where he wanted it. He requested to keep the originality and nostalgia of the story behind the car, out of respect and admiration, but knew he wanted to put his own twist on it. 

After many conversations on what outcome Mike was expecting, the journey of taking it in as the "Ken Stevens/034 Motorsports s4" and turning it into the "Mike Davis/Tweetler Performance s4" began. Starting off with the obvious, Reid had made a plan to turn this from a 2.7t Tial 770 setup to the 3.0L stroker Tial 770 setup. The engine was completely rebuilt by Tipcke Repair and involved installing 82.5mm Mahle pistons, IE con rods, and the obvious piece; the 3L crankshaft. Once Tipcke Repair was finished up with the bottom end, it was crate shipped back to our facility with a TDI 6spd transmission to be fully assembled with S.E.P Auto cylinder heads (upgraded to Supertech valves with 3% leak down results) and freshly powder coated valve covers and intake, then installed back into the car. 

This setup would need to have new fueling. Tweetler upgraded from stock lines to -8an feed and -6an return with an Aeromotive inline billet fuel filter, upgraded to Fuel Injector Connection 1100cc injectors, and installed a Kenne Bell boost-a-pump to improve the fuel flow by bumping the voltage to the fuel pump itself. 

After upgrading to all of these new parts and receiving a fresh AMD Tune, he was finally able to put down some power. Unfortunately, post dyno tune session, Mike had noticed a hefty vibration and especially under load. We took the s4 back in and checked wheels for balancing, motor/trans mounts, axles, and came to find the driveshaft was no longer able to hold the power the car was now making. We reached out to a local shop and had them make a single piece driveshaft from the OEM one. Safe to say Mike will likely never have to deal with drivetrain vibration issues again. 

Over the years Mike has been coming back to Tweetler Performance to have all maintenance and upgrades completed. Just recently had come in to have some aesthetically displeasing issues addressed. First one being the typical VW/Audi sagging OEM headliner, which was reupholstered including pillars, with OE style "Charcoal" Alcantara Suede, a compliment to his blue sport package interior and doubled to be that extra subtle touch of luxury.

While this was being completed, he had asked us about doing a full overhaul on his sound system that was fairly outdated and weak. So, a full set of Focal speakers, a 12" JL subwoofer, a 7" Kenwood double-din with integrated Apple Carplay, a 6-channel Alpine amplifier and adapter plates were ordered and installed the following week at our facility. 



All in all, we think it's safe to say that this is definitely not your dad's s4.

    Love what you guys did here! I have 2000 S4 I’m looking to have rebuilt (new engine, drivetrain, sound system and carplay)—what information do you need to provide a quote?
