    WE'RE ALL COUNTING ON YOU!!! YOU MUST PRESS ON!!!

    Also, that IC piping is freakin beautiful! Polished aluminum?

    Haha, it's getting there man! The pre turbo exhaust is fully welded including the Tial 44mm MVR wastegate I did yesterday. Still need to make the dump pipe for turbo and wastegate, but it's not a priority at the moment.

    On the intake side I need to weld the Tial Blow off valve, HPX MAF sensor, and MAP sensor flanges to the Intercooler piping.

    Oil cooler needs to be mounted and oil lines ran...

    I need to weld a -16AN bung to the coolant crossover pipe to go to the radiator...

    Radiator fan shroud is done, just need to cut out the 2 holes for it..

    I should be pulling the engine out today so I can mount the flywheel, clutch, and pp and after that I'll be ready to start wiring and hopefully get it started. A lot done, but still so much to do. I'm just thankful I dont have to touch the transmission, suspension, and anything else on the car once it's running. Just go straight to driving and street tuning.

    Not bad at all to be working on details that fine after 4 months of doing it on the side!

    You said BOV, but I thought you were running the RS6 ECU? You are planning on coding out the DV, i guess?

    A thought I just had (but it could be a bad one, it's barely formed), as I know you mentioned you were dreading the wiring harness integration, have you considered a standalone like VEMS (I know that one is the primary one used on the C4 cars)? Also, you could probably call Marc at EFI Express. He is crazy good on the C4 chassis ECU / Tuning side (He wrote me the chip for my RS2 injectors in my C4 S6), and might be able to assist. He does a lot of custom VEMS installations. I imagine the wiring / ecu part will involve equal assistance from the BCY & C4 communities, have you considered a dual thread on like motorgeek.com or theprojectpad.com?

    Generally having everything before started and not having to wait on parts has been great so far!

    I will be running the BOV in conjunction with the RS6 ECU with the help of the HPX Blow Thru MAF. Another advantage of the HPX MAF is that it's routed between the turbo and the throttle body (Instead of our traditional pre-turbo MAF.

    The wiring really isn't too difficult for me; I've just been saying it's going to suck... OBD2 might be challenging since I won't have the same modules as the C5, but I have 2 full RS6 harnesses and the entire RS6 chassis harness from the one I parted out. Shouldn't be too difficult. VEMS would be great, but I already have a very competent tuner when it comes to the stock motronic. Plus I have 2 ECU's...

    Funny, I started this thread on Rs6.com to help with the BCY end of things... MotorGeek.com to help with the C4 side... and the ProjectPad as a combination of both and fabrication...
    Each kinda serve their own purpose.

    Thanks for the support, the next update will be dope.

    Busy Monday, wrapping it up before I head to work tonight. Pulled the motor and installed the Steveken Flywheel + Ringer Racing Stage 4+ Clutch. Went on like clockwork...

    Since I'm running an oil cooled turbo, I don't need all the extra coolant lines under the intake manifold. The driver side cam gear has to come out which means taking the belt off. I wasn't going to do the timing belt, but it'd be stupid not to at this point.

    I have a -16AN going into the radiator so I figured putting one of the crossover pipe out simplify things. Exhaust manifold next to the valve cover meant it had to be modified. I'll run a 90 off of it and wrap it over to the passenger side fender, then back to the radiator.

    After the last fit up I found a few things that won't work. I'll need to run an 8" fan instead of the 12" for the passenger side. The main 12" fan will open at 180 degree's and the 8" fan will open at 210 degrees. I think that wraps up the cooling. Just need to cut and rotate the radiator outlet to clear the alternator and bing bang done. I have some cleaning up to do in the meantime...

    Replaced only the necessity in regards to the timing belt. Also opt'd for an 80 thermostat instead of the 87 in hopes to keep this beast cool... Hocky puck motor mounts are done as well. They are literally rocks; should be great for my back.

    All that's left to do now is wrap the manifolds and toss the engine in for the final time

    Been busy doing nothing lately. Got the engine back in with the flywheel + clutch kit and tested it to make sure I wasnt going to have the same hang-up as my first BCY 01e swap I did a year ago. Wheels are turning while moving the crank in gear and, yet stationary when out of gear... perfect.


    Made a big giant to do list, and going one by one knocking everything out. Aside from making a new oil feed line to the 76mm turbo and a drain line, I'm ready to start wiring in the harness, which aside from a spanner check is the last thing on my list...


    Spent all of today redoing the throttle body piping and radiator shroud clearancing among a few other stuff, and I'm able to get the front end on beautifully. [wrench][wrench]

    Front end/engine bay is 95% sorted.


    Time to start wiring the RS6 ME7.1.1 ECU and OBD2 into the C4 S6
