Building the Cold Side
I had bought this beast of an Intercooler from SheepeyRace before I got the cage done. It originally had a 3" inlet and 3.5" outlet. I planned on running a 3.5" from turbo to intercooler, and 4" from intercooler to throttle body. To make this all work, I planned on cutting off the 3" tubing to add a 4" and keeping the original 3.5" that was there.
Naturally, the tank itself was about 3.75" wide so it wasn't as simple as originally planned. I bought a 3.5" to 4" Merge from Vibrant that I modified to get a good, nonrestrictive transition. I had to weld very close to existing welds, so it's not the prettiest thing in the world but it ended up working perfectly.
I also added a 3.5" Aluminum V-Band and a 4" Aluminum V-Band to the intercooler. I did not want to have any silicone couples and clamps holding the tubing together. I blew those apart too many times and didn't want to have to worry about that moving forward.
Here, you can see the piping done from the turbo to the intercooler. The aluminum piping from vibrant comes out of the box extremely nice and perfectly polished, so I taped every piece to protect it during the fitment process.
Aluminum tubing from vibrant comes in a larger variety of bends than their stainless. Personally, I found it useful to mark all the different bends because it's not always easy to distinguish a 45 from a 60 by eye.
With the first section done, I wanted to mirror the bend on the other side to keep things symmetrical. Obviously, symmetry doesn't really matter for performance, I just wanted the car to have a certain presence when seen with the front end off.
Next was to connect the piece off of the intercooler to the throttle body. I went with Holley's Ultra Low Ram paired with an Icon Throttle Body from Motion Raceworks for hood clearance. To keep everything simple to work on, I added a second Quick Seal Connector so that final section would be removable. They are definitely a bit pricey, but it is very convenient removal and install with that style clamp and they take some stress off the 4" aluminum tubing between the engine and intercooler for vibration and slight movement.
Gawwwwwwwwwwwwdam. The vision I had in my head all laid out in real life. An absolute monster of a turbo setup all within the confines of a stock hood, bumpers, and fenders.
