    Thread: Stepping up to the 3.6 challange

    1. 11-30-2019 11:57 PM #1
      So my 87 GTI 16V has been sitting with a 2L old skool Momentum turbo kit that I never finished. Seeing you guys doing these swaps got me thinking about $/hp and plumbing and tweaking vs 300hp mostly stock, mostly bolts in solutions. Shazam I scored a 55k mile CC 4motion complete car as my donor platform. My contribution to Black Friday on Coparts live auction platform.

      Thus far I am sitting on

      1 low mile 02A CCM
      1 .75 TDI 5th gear
      1 MK4 shifter, cables, shift tower setup, destined for the Polo shifter solution, etc
      A good clutch

      Complete Fabless Manufacturing MK2 VR solution which moves engine more to the center. Includes axles. Its all deluxe, real nice.
      The mounts are currently in a little shop Oregon where a perfect Mk2 3.6 downpipe is being created.
      Car is still under 100K miles, Bilstein + H&R, G-60 brakes

      Plans are something like

      S&P Radiator
      Peloquin
      Keep the car and Engine on their individual fuse boxes and wiring
      Close up the power rack and go manual, or I do have an actual MK2 manual rack.
      Passat B4 TDI pedals for hydraulic clutch, perhaps the throttle pedal as well.
      Working AC
      Keep MK2 260 speedo and tach
      go with the Cayenne intake to get on the other side.
      Malone

      What about o2 sensors?
      There is no Bentley Manual for a B7 Passat. I downloaded a wiring scheme. Where, in the enlightened world, can I get Bentley level documentation?
      Will the oil pan be low?
      Any suggestions welcome.

      Oil pan is higher than a 12v. The wiring good luck, I took the easy way out.

      B3/B4 VR6 pedals are also hydraulic clutch. You picked up a donor CC, NMS Passat here the states is wired differently so better bet would to use wiring diagrams from 2012+ CC, and there is no Bentley and ELSA will help you way better.
      Current: R36 4Motion Wagon, MK6 Jetta SEL, 5N2 Tiguan SEL 4Motion

      Sounds like you are well on your way!

      The CC is actually the B6/PQ46 platform, though it did get some cluster and infotainment updates through the years. But the engine management will be the same as it was on a 2006 Passat.

      There isn't really a one-stop resource like Bentley for them or the 3.6 unfortunately. Have you seen these wiring diagrams? https://www.dropbox.com/s/c2knfvyz2d...agram.pdf?dl=0

      There is also this site which has shop manuals, some in Russian and some in English: http://vwts.ru/

      And there's this site as well: https://workshop-manuals.com/volkswagen/

      Thanks so much for the electrics.
      The donor carcass is arriving within the hour

      I been diggin on the donor. Man, really nice car and the best built, most integrated design of any VW I have gutted. I have sold the gauge cluster and the rear brakes already. I have looked at some dyno outputs and see why there are really no aftermarket power adders. These things make peak power at 6400 which is right with a well ported 1.8/2.0 16V head with a 276 cam. Its a real heavy breather right out of the box. Thanks for all the 411

      They made improvements overtime but haven’t changed the horsepower/Torque figures or dyno plots because that would require recertification of the engine, $$$$$$

      The later exhaust ports are larger, they changed intake manifolds and changed compression ratios and all resulted in no hp claim changes.

      6400 is nothing on these, mine peak hp isn't till 7200 and doesn't fall off hard until 7700.

      What year engine are you using? The 3.6 going into my Corrado is a 2008, and I daily drive a 2018 Passat GT. Is the difference in power going to be significant between the two 3.6s?

      Current engine is an 06 and new one is an 11

      There are some changes in manifolds and the exhaust ports but nothing earth shattering.

      Did you do valve springs or anything else to rev past 6400 to 7700?

      No, stock valvetrain. I tossed a rocker around 8200rpm last year.

      Thanks I'll probably need one. Does anyone have a line on a cayenne intake?
