Figured I might as well make a thread lol. Was hoping to sell it, but since a lot of members persuaded me to keep it, figured why the hell not.

I bought a bone stock CQ, and it was just too nice to hack up, so I did the next best thing and bought one with the swap already completed. Well, we'll say 60% done... Motor was in the car and running, but barely. Had the essentials hooked up to make it run. I've been tracing the hell out of wires to complete everything, but have high hopes that not too long from now, it will be a fun weekend car.

Brief Rundown:
AAN with what looks to be a fresh head, 7a Flywheel.
VEMS
Stock Turbo
FMIC
01A Transmssion. (Not sure if the clutch and PP are stock or not, will know if it slips when I drive it)

Day 1: Had the car delivered, drove the Red Coupe into the mountains and proposed to my fiance (At the point I figured I'd made a mistake buying it, but figured I'd keep it and slowly build upon it.)
Image


Car came with a milk crate to sit on, no seats, so for now I bought some off my room-mate from his Coupe. $20 and it'll be enough to get by for the meantime.
Image


Relocated the battery to behind the passenger seat to allow more room in the bay and opted for an AAN Valvecover for ease of breather setup.
Image
Image



Slowly began to pull everything out just short of the dash, kinda wish I had looking back at it now. Through about a weeks worth of wiring diagrams, schematics, and countless Forum and Small Chassis Members, I had a solid foundation on what wires need to run where etc.
Coolant Temp, Oil Temp, Tach, and Speedo... spent about a solid day with a multimeter and went to town. :woowoo:
For future swappy's, I will leave a list of what goes where in the comment section and how to properly hook up everything.
Image

All buttoned up. Still trying to determine the best way to hide the harness and ECU. :frustrated: Maybe make a bracket for it with the fabrication tools I don't have haha
Image

RS2 Replica Bumper that I had to cut to hell to make it fir with the intercooler. Painted it White today. Sooner or later I will respray the car in Alpine White (always been a fan, and I'm not yet sure I could tackle the 3 Stage Paint that Peal requires). After looking at it, it's a definite yes. Body work will start shortly on it to prep for paint.
Image
Image

Ordered some PJ US Headlights, only to realize I need to female connectors with pigtails. So once those come in I try and find time to wire those bad boys in. I feel clear corners are a must on any Audi so I went and bought another set off Ebay, same as the Red Coupe.
Image
Image

And that's where I stand today. Car need's brakes all round, headlights to be wired in, and then it will be considered, in my opinion, "Road Worthy". At that point (without going into boost, I will drive it down to an exhaust shop and have then weld up the 3" Downpipe to Magnaflow Catback and run a hood dump for the wastegate).

For future people B3/B4 go'ers that wish to do the swap. Here is what you need to figure out all the wiring for the gauge's. This is how I did it. A lot of busted wires with no continuity where there should've been so I ran all new 20 Gauge Wiring. My CQ has Autocheck for reference.

-Coolant Temp Gauge: From the Multifuntion Coolant Sensor, (Pin T Brown and Yellow). Run a wire from said pin to the Instrument Cluster T26 (Yellow Connector) Pin 2.
-Oil Temp Gauge: I believe the sensor plug in wire runs to the Grey T6D Connector as Connector Station 2, from there it just needs to be ran to the gauge (Will update once I'm 100% positive).
-Tachometer: The Engine Speed Sensor goes into 49/55 on the T55 Engine Harness. 40/55 (Output from G28 Speed Sensor runs to T6A (Pin 1 Violet/Black) From here I just ran a wire to T26 (Yellow Connector) Pin 22 of the Instrument Cluster.
-Wheel Speed Sensor: Once the Wheel Speed Sensor is connected to the Transmission, the wire travels to T6C (Pin 1 Brown/Red). I ran two wires from here. First to the ECU (50/55) and second to the Instrument Cluster T26 (Blue Connector Pin 20)

Here are a few references I complied.

In reference to the Wheel Speed Sensor: http://forums.quattroworld.com/s4s6/msgs/168463.phtml

Yea, the blue is horrible. So close to completely strip is everything short of the dash and both front seats.

The intercooler was from EBay (sigh) but that plus the EFK behind it means the temps never go above 95°c even on a hot day.

Stock AAN manifold with the inlet modified 2" closer to the front so I didn't have to go crazy with the radiator placement.

Headlights wired in, brake rotors and pads come in tomorrow.

Decides to stock with the stock setup for now. KW Coilovers are in the very near future.

Almost on the road :D

corner lights needs to go. you need the clear ones..

I like the big cut out in the front bumper. Are you going to make a grill for it?

I like the idea of a bolt in coilovers suspension that's proven.

Corner lights will be addressed very soon haha. Still trying to track down the sockets for those bulbs.

I probably won't make a mesh grill for it, kinda like showing it off, nobody knows what the hell it is haha.

Brakes are done, rear calipers replaced as well. Guess I should register and insure it and start taking it to work!

Got some sheet metal and riveted it onto the sunroof cutout. Figured it'll hold the water out better then the sunroof panel with duct-tape.

Not my strong side though...Image

Image

In other news, I drove it down to the gas station and back yesterday which felt great. Car feels solid and I'm ready to register it finally! :woowoo: I've had the mentality of hooking wires up, making it work, and properly routing it later. It definitly back fired on me yesterday when I pulled it back into the barracks, and the battery started hissing and smoking. Come to find the Battery + cable running to the starter welded itself to the turbo. That was fun...

Battery is surprisingly good. Added full coverage insurance just in case. Tucked the wiring for the starter and oil temp sensor into the frame rail so it won't happen again. Also need to clean up the driverside while I'm at it.

So freakin' close to driving this thing for real!

You relocate the battery in the trunk, right?

Haha, definitely got lucky and will not make the same newb mistake twice...

On a separate note, the clear corners came in, I was able to find the turn signal sockets (Thanks Jack Dean), and has everything wired up. Car is awaiting registration and then it's off to the exhaust shop!
Image

Image
Don't hate, but I think a huge wang would do this car justice once it's lowered! Haha. The Alpine White is definitly a go. Body work will commence tomorrow in the meantime while awaiting the title.

Hooked up the final gauge. Oil pressure is a go, and no more oil pressure warning lights and sounds.

For those interested in the wiring.

AAN/URS4 (6) side: http://12v.org/urs/UrS4OilPressureSende ... Sender.jpg

From there, I cut the leads at the respective T3 and T6 connectors at Connection Station 2, and ran 3 separate wires. 1 to the auxiliary gauges for oil pressure and the other to the White T26 in the dash (Pins 17 and 19): http://www.s2audi.co.uk/workshop/schema ... /page3.png

F22 W/BK Wire. Travels to T3m. This wire needs to connect to here.
Image
I spliced into this 2 pin connector since there wasn't enough room to work directly where the plug was.
Image

F22 BL/BK Wire. Travels to T6D/5. From there I spliced it into T26 Pin17 (White) at the Instrument Cluster.
F1 W/GY Wire. Travels to T6D/6. From there I spliced it into T26 Pin17 (White) at the Instrument Cluster.
Image

Hope it helps!

Got it registered yesterday and drove it to work today. Also gave my wife a ride in it for the first time (she loves it as much as I do) haha. Sent the video to my dad who is a huge B5 S4 enthusiast and he said it sounds like a Subaru. Can't please them all I guess

Video taken by wife of a little rowing of the gears.
