SLC cars SHOULD be okay here since the fan control module helps to supply power and only a single fan is on the 30amp fuse.

My question is that if your fans were drawing more than 30A, why didn't the fuse pop?
I think they were pulling less than 30amps. The fan switch died right after Wookies and when trouble shooting it I checked the fan fuse. For ****s and giggles I swapped in a different fuse and this other fuse didn’t make as good of connection and resistance caused a lot of heat.

I changed my motor Mount brackets and crossmember for the fabless manufacturing centering parts:








The about of clearance gained is amazing. I wish these parts were available early on. The 850 fab Downpipe won’t work with this kit but I’m not worried.
[/
Looking on the Fablessmanufacturing site for this crossmember kit and all I see is a kit for the OEM mount location. Was this a custom order, or am I misreading their description?

Lost momentum but with this prototype 3D printed project box I’m moving in the right direction again.

Derale fan controller mounted on a g60 intercooler bracket.

MSD high current solidstate relays mounted for the headlights, fogs and ac. Slowing working on the wiring.

There will be a lexan cover that slides up and down to shield the setup from the rain on the final version of the box.




Some brake changes up front so I could make room for an 8.5” wide LM wheel.

hey guys, i am working on sorting out a 3.6 swap into my mk5 r32 racecar build. i've dug into the wiring diagrams and turns out the most headache inducing part of it is sorting the power sources and comparing them to the passat/touareg equivalents.

that said, once i got my head refreshed on reading the diagrams (it's been a few years) it turns out to not be sooooo terrible. the 3.6 uses 2 main relays to power the ecu and everything else engine related, J271 and J670. turns out the mk5 r32 does the same, more or less, J271 and J317. i am going to list the outpouts of all 4 below.

2006 passat J271 powers
SB49, 50 amp, goes to J293 which is the fan control module
SB6, 20 amp, coils
SB7 15 amp, fuel pressure regulator valve
SB8 10 amp, cam solenoids and various other solenoids on the side of the engine, and goes to fan control module
SB11, 25 amp, ECU
J151 which is the coolant pump relay

2006 passat J670 powers
SB33, 15 amp, Primary O2 heaters
SB44, 10 amp, leak detection pump
SB45, 10 amp, post cat O2 heaters

2008 R32 J271 powers
SB6, 15 amp, fuel pump relay
SB7, 8, and 9 but they are empty, more to follow
SB10, 10 amp, MAF pin 2
SB11, 10 amp, Primary O2 heater
SB12, 10 amp, Post cat O2 heater

J317 powers
SB28, 15 amp, ecu
SB30, 10 amp, Cam solenoids and vacuum solenoids
SB43, 20 amp, coils
SB29, 5 amp, coolant pump relay
J496 to SB15, coolant pump

so, basically, it's all there in the mk5, just needs a bit of thought and pin rearrangement. of particular note though is that the ECU on the passat is powewred by a 25 amp circuit and the R32 is 15 amp, with the resulting smaller wire size. as with the state of SB7, 8, and 9, it would seem that a possible solution is to get terminals of the appropriate wire size and insert them in the connector into the panel. i haven't confirmed the possiblity of doing that just yet as i am concentrating on prepping the shell still but that will be plan A in the new year. i haven't compared the R32 with other mk5 arrangments as my head is still hurting lol, but it should be similar i would think. when i get to actually moving wires n stuff, i will post up what i actually do. one other difference of note is that the MAF is powered differently between the cars. on the passat, the MAF is stil powered by J271 but that goes to another relay, J329 and then powers MAF pin 5.

anyways, more to follow in the new year when all my parts get here, will keep adding to this as i can. hope this helps someone else too.

3.6 24V VR6 Swap Questions & Links

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

In the end I ended up using the stock 3.6 manifold
Wow this is a great 3.6 liter build swap thread here man. I have to ask though out of the six different 3.6 liter donor swaps starting from the list below.
What's the difference in performance and the steel that they're made from? Are all these 3.6 liter blocks made out of the same type of steel if not what makes them different? I was really aiming towards the Porsche Cayenne 2006 and up for my next swap.

3.6 24V VR6 Swap Questions and Links



This Corrado R36 build thread is intended to be a resource for those wanting to do 3.6 VR6 swap. Let me first say that my car has gone through a lot configurations since I first started it in 2016. There are a LOT of different combinations of parts that work well together. My thread might be confusing as to what the best path forward is for you. Read all of it and if it seems confusing ask questions and I'll try to shed some light on it.

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. in 2016 this swap was 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 at some point (its changed a lot over the the past 5 years)
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: Mk2 Corrado or Passat 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:
--- Wiring Harness Services
--- Eurokraft Performance
--- http://shop.eurowise.com
--- TDC Shop
--- https://stancedubs.bigcartel.com/product/fsi-swap-harness-for-mk2-3-4-chassis

For those that want to run Standalone
Paul (Need_A_VR6) contact Paul at his site: 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 reposition 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

Wow man this has to be one of the best 3.6 liter VR6 build threads I've ever seen. Great detailed write up for sure! Out of the six different 3.6 liter 24 valve VR6 engines ranging from the list below. If they are all the same horse power then what are the differences between them? Are some of the blocks made from a different type of steel? If so what's the best 3.6 liter 24 Valve VR6 to go with? I was aiming for the Cayenne one that seems to be my favorite out of them all.

I’m not sure what the reported hp/tq is on the cayenne. I also don’t believe any of reported VW hp/tq ratings, I say this because I once looked at all of the reported ratings from 2006-2013 or maybe 2014 and they were all for the most part the same. One person told me this was mainly due to the federalization process.

That said I would take any forged crank 3.6 VR6. I think the forged crank 3.6 engines probably all have the large export ports and probably the same or better hp ratings of the BWS R36 engine.

I’m personally running a 2017 Touareg 3.6 engine. I’m not a fan of the Porsche intake. I don’t like the look or the 1 piece design.

I think the Passat/CC black intake is better than the Touareg intake because the Touareg intake has an ugly flap between the 3/4 runners on the front of with a vacuum valve.

They are all basically the same engine. Tuning gets changed with a swap file. KP tuning sells aftermarket cams if you want more cam. Get a good fairly low mile engine and call it a day. If you don’t get low mileage then you will end up having to to timing and who knows what else.

Yeah it's funny how many little bit of a difference there is with these intakes on these 3.6 engines. Besides KP tuning I've always been a fan of Tectonics there 268 cams works great in the 12 valve VR6. Would you recommend Tectonics cams for this 3.6 engine if so what degree of number would it be?
I hope you enjoy your Touareg engine for the new year. Thanks again for your help on this I appreciate it.
Also do you know of any shops on Long Island that specialize in Volkswagen motor swaps?

Techtonics doesn’t make 3.6 cams or if they do it’s a new development.


I don’t know if any shops that are really interested in do this swap for anyone. EuroKraft is super backed up at the time and he isn’t on Long Island. He is in NJ. Login • Instagram

TT doesn't have any cams yet for these. I talked to Collin about it awhile ago and even asked for blanks to get some made. No luck though. Cat has a few that we import but not many takers. I am well over 300 whp on a bone stock motor and its hard to argue you need more than 280 whp in a simple na street car.

I would recommend Matt as well for the swap, as few have all the skills and the right mindset for it.

Oh well Tectonics has always been my favorite for after market high performance parts. I'll be probably have to go with KP tuning cams then along with the swap file. That is sounds like the best options at this point.

I never heard of Euro Kraft, it sounds like a good shop.Yeah it's hard to find a good shop that does custom swaps like that these days and if you do there always backed up a couple months or so.
Thanks again for everything.

The complexity of the swap is more than what most shops/people are capable of or more than they want to take on versus what people would be willing to pay. It requires a lot of attention to detail. Matt/eurokraft has been one of the underground masters for a long time just like KP tuning.

Very true and good point it requires a lot of attention to detail especially the wiring loom. It's just too overwhelming to people because of the complexity of the modifications like engine mounts and that kind of thing. I would imagine it would need a custom flash for the ECU as well, then again that's what the custom swap file is for. KP tuning to the rescue lol!

Thanks for the recommendations this guy Matt definitely sounds very experienced and the right guy to get the job done right the first time. But I'm from Long Island and he's in Jersey so unfortunately that's too far.
What if somehow or another someone started some type of group buy here on VW vortex and reached out to Tectonics tuning to see if they would make them for the 3.6 VR6.
I know it would be costly but you'll be surprised how many people like this swap. Hey you never know. Just throwing that idea out there.
Yeah that's the great thing about the 3.6 VR6. 280 horsepower is the perfect power combo for these cars and yet people still like to add more horsepower to them. I wouldn't go any higher than 300 HP at that point you will probably experienced to much over steer and traction control problems unless you had LSD LOL!

Jersey is close and a quick down and a half day trailer trip. Totally worth it.

I wouldn't even do one of these for a customer build unless I had their bank account pin. so many variables and a lot to go wrong.
I rather stay local it works out better for me that way, but thanks anyway. I would never take my car to a shop for somebody that would ask for my pin personally that's a little sketchy. Are you a professional certified mechanic?
