For Audi enthusiasts

Recently we introduced our Project Audi TTS:SF project car series complete with video webisodes. In this installment we’ll cover a few initial installments that have upgraded the car here and there before we begin to really delve into upgraded components. We’ll go over what pieces we have swapped out and what the rationale was for doing so. In most instances, so far we have traded out OEM parts for higher strength pieces to reinforce for planned power increases. There were other parts that were exchanged for maintenance reasons, and still others were traded for subtle aesthetic enhancements.

Let’s start with the appearance pieces first. Northern California firm J-Caps produces Billet Aluminum cap covers for the Audi’s engine bay. We met the owner Jay, an enthusiast in the scene, at a few GTG’s and his parts looked intriguing. We picked up a set shortly after the TTS was acquired – one of those quick and easy modifications to personalize a new car. We installed the oil cap, coolant cap, and dipstick ring cover. The parts are lightweight, high quality covers that snap over the top of the existing OEM caps and tighten down with an allen-head set screw. Easy installation and it’s just a quick inexpensive way to give the engine bay a bit of luster.

Due to other plans, which you will see in Webisode 3, the TTS needed a Cold Air Intake that really fit the engine bay in a specific way. Since nothing on the market had the footprint we wanted, we acquired an AEM CAI for the Audi A3 and repurposed it to work on the TTS. I had previous experience with this intake on an A3 and loved the build quality, fit, power and sound. So after paying a visit to the local metal shop and getting few snips here and there as well as buying some big-rig turbo hoses, we were able to build an intake that has worked very well so far.

Now let’s talk about strength building and maintenance. The Forge Motorsports Diverter Valve is one of those modifications that just makes good sense. Going to an all-metal version of the DV to cope with higher boost levels even for a Stage I upgrade is a solid foundation for a trouble-free build. The piece sits atop the Forge recirculation spacer, which adds a bit of liveliness to the sound of the engine without going into the wretched corny import tuned car sound. It’s just enough to give the 2.0t some vocal character.

The last bit of kit in the engine bay is a Forge Oil Catch Tank or OCT for short. This is a brilliant idea, as it aids in filtering out hydrocarbon buildup in the engine. Essentially it pulls out the contaminated “blow-by” sludge, caused by un-burnt fuel. This is definitely more of a preventative maintenance type of mod and based on the first 2-3 drainings and all the garbage that it pulled out, I would highly recommend the Forge OCT.

Going from inside the engine bay, to inside the cabin, we are now running the famed Valentine One radar detector. If ever the phrase “truth in advertising” rang true, it would be with this amazing device. This piece has saved me from more tickets than I care to speak about. Let me illustrate it this way. I enjoy what I’d call spirited driving. I also have a 100% clean DMV record. Again, the V1 is a must have if you really like driving your car hard. We also incorporated the V1 remote display module that some eBay’r modified for me to incorporate colored LED’s to indicate what radar band being used. We mounted this detector on an ipod ring sourced from MODShack for a stealthy look.

The final interior modification is an AEM Tru-Boost gauge. It is for the most part a digital interface that displays boost levels in numbers as well as a sweeping color readout. This gauge can also be configured to a stand-alone engine management system to control boost levels, but that will likely not be the direction we head in this build.
