      This Corrado R36 build thread is intended to be a resources for those wanting to do 3.6 VR6 swaps. I would like help with questions that pertains to 3.6 swaps as well as compile links to other resources that help with the 3.6 knowledge. I did something similar for the TDIClub when I was doing my 1st TDI swap and it has been fairly helpful to the VW community for those that want to do TDI swaps to the point where TDI swaps are now fairly common place. I think with a common pool of 3.6 FSI knowledge this swap will become the new why not swap. Right now its a little beyond most people's knowledge level.

      and dozens upon dozens more, its easier if you ask where to get something than to list all part suppliers.



      Parts necessary for the Corrado swap as I’ve done it
      Engine Parts
      -Passat BLV Engine & Harnesses
      -2007 Touareg BHK ECU (I used this so I could use a mk4 gas pedal which is easier to install and looks more OEM)
      -Passat intake fuel pump and control module (people have used regular fuel pumps and a relay)
      -850fab Downpipe works great with 3.6 manifolds
      -Mk3/SLC rear motor mount bracket
      -Fluidampr crank pulley (I initially test fitted a touareg block and the crank pulley was HUGE, it hit the frame rail. The Passat BLV pulley is smaller and should fit the corrado)
      -S&P tuning drive by wire pedal bracket for the mk4 gas pedal: https://s-pautomotive.com/product/mk...t-dbw-adapter/
      -mk4 gasser gas pedal

      Wiring Harness

      Off the shelf wiring harness in 2-52 weeks:
      -For those that don't want to save the $750-$1,000 you can have one of these tuners build it for you:
      --- https://s-pautomotive.com/product/wi...rness-services
      --- https://www.facebook.com/eurokraftperformance
      --- http://shop.eurowise.com
      --- https://www.instagram.com/tdc_shop
      --- https://stancedubs.bigcartel.com/pro...k2-3-4-chassis

      For those that want to run Standalone
      Paul (Need_A_VR6) contact Paul at his site: https://kptuned.com/ he has recently run a 11.638 in the 1/4 with his 3.6 Corrado on his tuning. He is in the process of having intake manifolds made and cams ground for the 3.6

      For those that want to build your own harness
      -I made my harness I used the wiring diagrams from the corrado manual, Passat and touareg as well as one of the pinout sheets that I've taken substantially updated. (linked above) Wiring is not easy and you might not like where the harness makers install everything or the amount of wire they supply. Hence why I made mine. You will save a lot of frustrations by buying it, but when things don't work you have zero luck in trouble shooting it by not going through the learning curve of how things work together.
      -2 CE2 add on relay sockets
      -6 CE2 add on fuse sockets
      -Mk4 Beetle OBD2 diagnostic port and bracket there was an OBD1 plug in 1994 corrados and if you wanted to be an anal corrado guy you could go that route. I didn't because I didn't know about it when I installed my OBD back in 2008.
      -3M Friction Tape p/n: 3407NA
      -A bunch of TE terminals in various sizes
      -A lot of heat shrink tubing with glue on the inside

      Accessory Bracket

      -MK4 24V VR6 accessory bracket
      -3.6 accessory belt tensioner pulley
      -MK4 24V VR6 belt tensioner
      -MK4 24V VR6 Power steering pump (I've been told a 12V PS pump and pulley will work)
      -Mk3/SLC VR6 AC compressor
      -3.6 Passat Alternator 140amps

      Oil Filter Flange

      -Passat BLV is the same as the other transverse 24V oil filter flanges
      -I had two ports welded on
      -I also used G60 brass oil pressure fitting that’s found on the head for the super charger oil feed line. I think the Vr6 corrado also has these too.

      Pie-Cut Front Motor Mount Bracket

      -Steps to make a pie cut front motor mount bracket
      -Could have used the 12V VR6 oil cooler but it was still a tight fit
      -Will require a shorter starter bolt as found here

      Coolant hoses

      -Front end hoses
      -lower radiator hose is a combo of a G60 lower radiator hose, VW t fitting with temp sensor Flange part number 1c0121619C and the Passat blv lower rad hose
      -upper is the Passat blv lower rad hose, comes with the lower hose and a custom SS pipe I fabbed up.
      -the heater core hoses are the same heatercore hose from a mk3 that runs from the side of a 2L Head to the HC. I cut them down.
      -the coolant bottle hose is from a mk3 tdi.
      -I replaced the BLV’s coolant temp sensor with a mk3 TDI temp sensor part number 357919501A to support the ECU and cluster from one port.
      -I used a MK3/SLC Electric Coolant pump

      Transmission
      -I used a CDM VR6 02A from a corrado with a Tdi 5th and Peloquin lsd
      -southbend stage 3 daily clutch after having a stage 3 clutchnet issue and a stock Sachs failure.
      -stock 12V VR6 flywheel with ARP Flywheel Bolts
      -I used a mk4 02J starter because I like the bendix and how it doesn't go into the bell housing.
      -Dieselgeek Sigma 5 02J short shifter
      -Polo 02J Shifter

      Exhaust

      -Made my own downpipe 2.25" to 3" the person who did the welding for my fab work now sells them 850fab Downpipe works great with 3.6 manifolds and MK5 R32 manifolds

      ****NOTE THE 850fab Downpipe fitment doesn’t work with the FABLESS VR6 Swap Kit mounts and cross member that repositions the engine****
      850 Fab's individual mounts and cross member doesn't resposition the engine and works with the 850 Fab downpipe.

      ****also note that I don’t have any connection with 850Fab other than I paid to have him weld my downpipe and he then made a jig from it. I don’t make a cent off the sales of that part or any other parts sold by other 3.6 swap part sellers.

      I do sell 3.6 wiring harness cores to people but that’s all I get into. I don’t want to deal with end users issues and hence why I’m not a business.

      Throughout my swap I had to test fit, re-engineer parts and then start over to get my car running to the point where I could rack up lots of joyful miles.

      -3” Downpipe back with a cat, resonator and Borla muffler.
      -I used a 3” Stainless Techtonics Over the axle pipe, call them up to order it.


      Intake

      -Started with a Swoops built hidden MAF
      -had it modified to have a custom 5" velocity stack
      -K&N filter
      -83mm

      In the end I ended up using the stock 3.6 manifold

      For my Corrado swap I thought about using 2.8 24V manifolds or 2004 R32 manifolds (there are probably a bunch of other donors) that point straight down so I could use a TT downpipe with a single outlet.

      Here are the different manifolds

      Do all 3.6 motors have watercooled alternators like the touareg motor I picked up the other day?

      From what I remember the non fsi engine manifolds have a different bolt pattern and are not a direct fit. At the very least you will have to redrill.

      The Passat blv accy bracket works nicely with the older alt. I had some clearance issues with the short runner so I am running a 2.8 24v tensioner on the head and cut the one on the accy bracket off.

      No. The alternators are non watercooled. Quick vid of mine from B6 (scavanged from a bit).

      Good to know about the water cooled alternator. I was asking mainly because the Touareg block I have has the port in the block and coolant pipe.

      The accessory bracket I have from the Touareg has a power steering mount but unfortunately doesn't allow for the Corrado AC compressor to be mounted. I'm going to take a look at the Touareg compressor and its fittings before I seek out a 24V 2.8 bracket.

      I'm currently trying to decide on what oil filter setup I might use too. I have a nice remote setup installed in my car so I'm leaning towards the 034 flange.
      https://uploads.tapatalk-cdn.com/2016...8ad528f1e6.png

      I just wish the ports were 10x1.00 for the oil sensors.

      I ended up using a stock 24V Oil filter flange assembly with extra ports welded on.

      Nothing wrong with the stock filter setup no huge advantage to remote other than cheap ford filters.

      Great idea for a thread, most swap posts here start with someone asking a question, someone else posting an unsourced photo of some amazing swap, and then the whole thread going dead. Hope this one keeps going!

      I maintain a 3.6/4motion-specific info thread in the B6 forum. No swap-specific info but it might be useful:

      Here is a link I have been using to look up part numbers: www.7zap.com

      I haven't torn apart my core long block yet but I can't find the part number for the valve guides. Has anybody ever replaced these yet? Thanks

      Wouldn't the guides be the same as the 3.2?

      Probably it looks like they use the same valves.

      The crank pulley was right on the frame rail but it's the Touareg crank pulley. I have one that's thinner on the way from fluidamper.

      Im doing a 3.6 into a 2004 GTi VR6

      Donor was a 2006 passat
      So far I have

      Motor
      ecu with harness
      Gas Pedal
      FCM
      Mk5 GTi fuel filter
      Passat body harness to hack up for plug and play setup using a spare MK4 harness

      Its a straightforward swap if you have common sense and some literature. Have your tuner code out **** you don't need and its a breeze. Good luck to y'all

      I brought home a running swap with a bad rear diff today and after doing a couple do swaps I'm certain this shouldn't be too bad.

      I've been meaning to finish up my thread with the swap info. The wiring was surprisingly easy.

      I think there was about 12 wires that went from the chassis harness to the engine harness. Still toying around with the wiring diagram since a lot of changes were made on the day we fired it up.

      Good job. Did you end up using aftermarket cruise control?

      I haven't got it wired in anymore, I'm still tidying up the swap. It looked promising to make the stock pedal work, but it kept getting EPC lights. I ended up using a brand new MK7 pedal flawlessly. Bolts to the firewall relatively well.



      I sent the ECU away to get a couple phantom check engine lights removed, so once it's back I'll tinker with it more. I ended up needing a new fuel pump because the stock one was causing lots of hesitations.

      Did you use the fcpm modulu to pulsate the stock pump? So the mk7 has a upside down pedal? Might have to look into that since the passat one is huge

      I did use the FPCM. I also retained the stock Fuel Pump Relay.


      The MK7 mounts a lot lower than the the MK4 pedal, but it avoid slicing up the floor. Looks like MK4 pedal covers will fit on with no issue as well.

      Was it a direct swap or did you need to use the mk7 plug? Also did have the same values as the b6 Passat pedal ft the ecu or did it take custom coding?

      Thanks

      MK7 pedal (any pedal works, I tested with a TDI pedal) works with the MED9.1. The B6 pedal gave codes in my brother MK7 TDI. I just ran basic settings for all the pedal related things and I haven't had an issue. The plug looks different, but you can plug the B6 accelerator plug into the jack on the MK7 accelerator.
