Hi Everyone,
I figured I should do a quick introduction since I didn’t in my last post. I have been a long time car nut, be it from playing with Hotwheels to picking up my first project car, my senior design project, known as FSAE, my Audi(s), or helping friends with their cars, I’m daily wrapped in cars. If any of you are familiar with FSAE, you will know that I’m a mechanical engineer, a fresh one at that since I just graduated in May and am now pursuing my masters. Now back to the cars. The first car I picked up was a Datsun 260z with the intent of swapping a skyline motor into, a RB25det to be exact. I’m still working on the car, but college and Audi’s have slowed progress down. I bought a 2004 s4 back in 2013, as some of you know, it recently went to the grave yard. Hopefully someone was able to pick it up for a good price and put that motor back into another car. I now recently own an RS4 and last week did a carbon clean on it, so I will go over that later on too.
Here is a picture of the Datsun as it sits. It doesn’t look to crazy from the out side, but is a little different under the hood.

Here is the engine that I put in it, don’t worry this is just the beginning.

The next car project that I was majorly involved in was FSAE, this is a undergraduate program for engineers where we get to design, build, test, and race a car. It is an extremely fast pace program at my school where we have 1 1/2 years to do all of the above. I was personally responsible for the engine team, where we got to make a custom exhaust, intake, cam sensor, do all of the tuning, basically everything besides build the engine block and turbo. We ended up turbocharging a 2014 KTM 450sxf engine, unfortunately, I couldn’t say how much power it made, but it was around 70hp, mind you this was with a 20mm restrictor before the turbo. All in all it was a fun project, and I learned a lot from it. Below is a photo of the racecar.

The RS4. This is, in my opinion, the pinnacle of the of the Audi 4’s. Mine is a little higher in mileage around 100k, but still drives great, and even better now that I did the carbon clean and a couple of other things here and there. The car has the alcon/stasis BBK with the Mono 6 pots. It is also sitting on stasis CO’s. I’m not sure of the exact type, I believe there were a couple different coilovers they sold for the car, correct me if I’m wrong. I haven’t put the car in the air to see what it has. I will let the pictures speak. For those that are curious as to how I did the cleaning, I used brake cleaner, a brush, and a cheap harbor fright media hopper with fine walnut media to clean the ports.

I also installed some JHM spacers while I was in there. I pulled some data, from before I did the clean, but I need to go pull some now that I have cleaned the intake. I will post a comparison once I get some time.
For the bad. When I had the intake off, I also changed out the sensors for the flap position. I know keep getting a EPC, and MIL, because of the flap positions. I have been looking around in VCDS to see if there is a way to calibrate the sensors. I’m sure the values that they are sending the computer is different than what the other sensors where sending, so it seams like this would affect the ECU. Does anyone know if there is way to correct for this? Could I have installed the sensor wrong? It seems kind of hard to install it wrong though. Any input on this would be appreciated.
This is just the start of this car. I have a lot planned for it and will try and keep you guys updated with things I do to it. It is hard since I’m working full time and doing graduate school full time though.
