Audi Tuning | VW Tuning

It almost looks like a car again! The new serp tensioner came in, so I put than on and tightened up the serp belt. With the serpentine stuff all done, I proceeded to move over the fans, radiator, etc to the new core support. For those of you replacing radiators in the future, the couplers are just friction fit.

Once I got the core support on, I added/flushed fluids. I added new G12+, Mobil1 5w30, and flushed my P/S fluid.  We test fit the hood and bumper, everything lines up well. It needs some fender adjustment and some more brackets, but it looks damn good! The hood has some poor paint/resin (EuroGear) that will be fixed before paint.

Car should hopefully be done by the end of the month, but of course, this depends on parts and what not.

What can you do in 12 hours? How about swapping 75% of the body panels on a B6 S4? This trip to JMI was quite rewarding as I was able to replace all the doors, remove the front core support, replace both front fenders, gut the interior, and remove the rear bumper.

With the vehicle in service position I thought it would be a good time to do some maintenance and mods. Valve cover gaskets, JHM intake manifold spacers, JHM lightweight crank pulley, JHM heater elbow bypass, and a new water pump and thermostat all ended up in the car.  I’m also relocating the Optima Yellow Top battery to the passenger-side trunk which should help balance out the weight of my sub all-the-while removing weight from the front of the car.

Anyway, here’s the progress so far…not bad for one guy and 17 hours!  (If he must say so himself – Dion)

Today marks the beginning of Jon’s new project, the transformation of his 2004 Audi S4. Due to some unforeseen circumstances, the B6 S4 will be getting a little refresher.

The plan is to do a complete OEM wide body conversion and transform this B6 S4 into a B7 RS4. This involves replacing exterior panels on the car and then some! He’ll be replacing the Oettinger front bumper with an OEM RS4 bumper which he plans to incorporate the S6 LEDs into the fog light area. This should be an easier task then the installation of the lights in the Oettinger kit since the openings in the bumper are a little wider. Jon will also be replacing the S4 blades with those found on the A4, or even RS4 blades… Jon wants to see how fitment is with the A4 blades first. The Kerscher side skirts will be replaced as well. Once all the exterior work is done, Jon has an RS4 steering wheel and a B7 center console that will need a new home

Since Jon’s S4 is a B6, the hood and headlights will also need to replaced; luckily he was able to source a set of complete headlights and a Eurogear CF hood with Aerolatch hood pins already installed from a fellow Audi driver for a GREAT price! Plans will be to color-match these pieces to the body. Stay tuned as we update you with the progress of Jon’s RS4-conversion!

After a few weeks in the shop, we installed the STaSIS 4:1 center differential on my B6 S4. The stock differential provides 2:1 torque distribution, with the modified STaSIS unit we’re able to provide 4:1 just like the B7 RS4.

I have not had a chance to take the car to an HPDE yet, but I have noticed an immediate difference coming out of the apex of a corner. Typically when you’re exiting, the car begins to under-steer; with the diff the moment you begin to under-steer the power is transferred from the front to the rear and we can neutralize some of this under-steer.

There has been no odd behavior from ESP or ABS. The only thing I’ve noticed post-diff has been some Quattro binding at low speed turning, such as in parking lots.

This modification is available for 5 and 6 speeds, manual A4/S4s.

The install was simple, expect approximately one hour for the install and reinstall. Start by disconnecting the center drive-shaft. The drive-shaft is held in by six allen key head bolts, be careful not to strip these. We heated the bolts with MAAP gas to loosen and burn off any Loctite.

Once the bolts are out, the Torsen housing can be removed, and the differential can be removed. Slide in your new unit, refill the transmission fluid (it’s shared with center diff) and you should be good to go!
