Turbo Removal
Time to remove the turbo and all of its components. It would probably be
a good time to take a small break and grab a coke. This next part is 
tricky and time consuming. Having a friend would help, but I did it by 
myself so it wasn’t impossible. Plus, there is really only room for one 
hand

1. Remove the Turbo Support bracket: (2 x M10 XZN) Rear bolt is EXTREMELY close to the axle, you might need to have short (M10 XZN) to access this. I used the XZN bits from AutoZone cut off and (1/2” Combination Wrench
   
2. Remove upper section of turbo support bracket: (6mm Allen) Place bracket to the side. Nut is welded on, so don’t worry about it falling
3. .
4. Remove Coolant Return at the Turbo: (Short M12 XZN + 1/2” Combination Wrench) Just like the turbo support bracket, you should have plenty of clearance.
5. Disconnect Oil Return on the bottom of the turbo: (2 x M8 XZN)
   The picture isn’t very good, but you WILL be able to reach it. It might
   benefit to have a longer M8 XZN. The view is looking UP from underneath
   on your back after you have rolled in from the front of the car.
6. Remove Oil Supply Line Bracket Under DV: (M8 XZN)
7. Disconnect Coil Packs and route harness to the other side of the engine bay
8. Disconnect Oil Supply Line on top of the turbo (M12 XZN): Push to the back and out of the way
9. Disconnect Coolant Supply Hose (Channel Locks or Vice Grips): Just undo the clip and pull the hose off the hard piping. Route it out of the way.
   
10. Remove Turbo (5 x 13mm) Nuts: Some studs might come out, just be sure to chuck these up and remove the nuts and place them back into the block. None of my studs came out and I have around 40K on my vehicle. Picture is from the backside of the manifold
11. To lift the turbo out, pull manifold away from block studs and angle the turbine side upward and wiggle it out of the top. It took me a little bit, but I found the compressor outlet was hitting the block. Once I got it free from the block, the turbo was MUCH easier pulling out
    from the top

Bench Work: Swapping IHI to K04
Awesome Job. Now that you have the turbo out, pat yourself on the back and take another break, or continue on. The rest is simple, but you must make sure you are aware of what you’re doing, because you could be in for a headache if you mess something up.

1. Assemble DV (Purchase a REV D valve!) to K04 per APR’s instructions (3 x 5mm allen + lock washers). Make sure they’re snug
2. Swap (6mm Allen) Coolant Plug per APR’s instructions. Torque to 38-40ft-lbs. Plug Location was triple confirmed by APR’s service department
   
3. Swap Coolant Supply line from IHI to K04. BE SURE to follow APR’s instructions for washer placement. DO NOT put the thicker washer on the coolant line you are currently swapping. This washer is for the firewall
   side line. I made the mistake and reinstalled everything and had to pull the turbo a second time to swap them out. Torque to 20NM (18.5ft-lbs) + 45* (You will not be using the 8XZN bolt from the bracket.)
   
4. 
5. Swap Vacuum Line from IHI to K04. Be sure to use Oetiker clamps provided. (I used a small pair of nippers to clamp). The line had a little play in it so I wrapped some high temp electrical tape around it to provide adequate clamping force. That might not be needed for other 
   installs
   
   
   
   
6. Install Downpipe Studs provided in the kit. Be sure the smaller end is installed into the flange. Don’t destroy the threads, but make sure they’re snug. You will torque these later
7. Install APR Supplier Silicone Connector at the same angle as the Stock Turbo’s compressor outlet. This will help later.

Re-installation du nouveau Turbo

Now you’re ready for the full install. Make sure the engine bay is free 
from wires, connectors, lines, etc. etc. You’ll need as much clearance 
as you can and plenty of hand room. I have smaller hands and I don’t 
know the variation between big hands and small hands when installing the
turbo. No pictures will be provided for reinstallation of everything.

1. Install K04. It would be wise to angle the compressor down first for easier fitment. Make sure you’re aware of the silicone adapter. You might need to go underneath and guide it away from the block. Once that is situated the turbo should just slide into place. Make sure you place the turbo into the Vblocks on the engine. Basically when I was aligning the holes to their studs, the manifold sort of slipped into the blocks naturally. Be sure in install the gasket the same orientation as the IHI(Tab faces driver’s side)
2. Hand tighten manifold nuts on the studs
3. Taken from GolfMKV: “When torque-ing the turbo to the head, there is a very specific sequence to follow. Let’s label the nuts 1 thru 5, starting from the passenger side. The sequence to tighten them is: 1, 3,5, 4, 2. You have to make five passes in that exact sequence. The firstfour passes will increase torque each time, starting with 5 Nm, 12 Nm, 16 Nm, and then 25 Nm. The fifth pass should be made at 25 Nm again,to verify nothing has changed. If you get any rotation on the fifth pass, make another at 25 Nm until the nuts don’t rotate.” I believe thisis the Service Manual process. (13mm)
   Install Oil Feed line to the top of the turbo. Don’t forget to use new washers on either side of the banjo bolt. (M12 XZN) (20NM + 45*)
4. Install Oil Return Line. Don’t forget to use the new gasket. (2 x M8 XZN) (Torque: 9NM)
5. Install Coolant Return Line. Don’t forget to use new ashers on either side of the banjo bolt. (Short M12 XZN + 1/2” Combination Wrench) Tighten the bolt well.
6. Install Coolant Feed Line onto the hard piping to the left of the block. I would make sure the clip is facing in a convenient location
7. Install Turbo Support Bracket
8. Install Pancake Pipe
9. Reinstall Heat shield
10. Install vacuum line to block
11. Install lines onto heat shield
12. Connect DV and N75 connectors
13. DO NOT CONNECT COIL PACKS YET
14. Install downpipe per APR’s directions (or other vendor)
15. Install splash shield
16. Install battery
17. Install Intake
18. Install Battery (tie down and connectors)
19. Install Passenger Fender liner
20. Install Passenger Wheel (90ft-lbs)
21. Check work and make sure everything is snugged up
22. Fill Oil
23. Check EVERYTHING again
24. With the coil packs still unset, turn the engine over to allow the oil to recirculate into the turbo and throughout the system for about 30secs. Since the coil packs aren’t connected, no spark will be delivered to the chamber and the system will not turn over.
25. Connect coil packs
26. Leave ECU in stock mode and crank the car up. Let the car idle and run for a few minutes
27. Check for Leaks
28. Shut the car off and fill 50/50 Mix of coolant to appropriate level.
29. Go for a test drive. Do not go crazy. You’re basically just checking whether or not you broke something or you missed installing a part.
30. Check for leaks again
31. Troubleshoot if needed
32. Reinstall engine cover
33. Place your ECU in tune mode and go have fun!!
