Background:
The DBV2 turbo inlet elbow has been my go-to elbow for testing various intakes with the Mabotech M520 hybrid turbocharger. It is well-matched to the larger compressor inlet size and correlates with the best performance data I have logged.
The only issue I have encountered is that it is made for the Mk7 PCV system, and I am using the Mk8 PCV on my GTI. The problem is that the Mk8 hose includes a vacuum suction pump at the connection to the PCV port on the elbow, increasing the height of the part.
The increased height and orientation of the PCV port made it hard to attach the PCV hose to the elbow without hitting the firewall.
This is a similar problem to one I have with the Blaze ATOM intake, although the situation is bad enough with the Blaze that I made an adapter to relocate the connection point.
This adapter lets me connect the PCV hose away from the engine firewall.
Change:
Because I use the DBV2 elbow most of the time, I wanted a better solution than making another adapter. I contacted DBV2, and they offered to modify the elbow by relocating the PCV port so that the Mk8 PCV hose would not be cramped at the firewall when attached.
I recently received the elbow back from DBV2 with the modification, and the Mk8 PCV hose fits much better now.
I want to thank DBV2 for their help with this change to the inlet elbow, which allows me to attach the Mk8 PCV hose to the TIP more easily.
With as much swapping of intake setups as I have been doing, I value having parts that are easy to remove and reinstall.
How much did it cost to have the PCV port modified? I had the same issue with my DBV2 and ended up cutting off the TIP arm that connects to the turbocharger, moving the arm back toward the firewall about a quarter of an inch, and re-welding it to allow the TIP to swing more towards the front of the car for more clearance. I was nervous because it was very difficult to get the measurements and I could only move the arm back so far because the TIP notches had to line up to the TIP guides on my stock is20. Only about 1/4th of the notches are sitting in the guides currently but I did barely get the clearance and I don’t seem to have any issues regarding the arm adjustment. I wish I would have seen this earlier though. Adjusting the PCV port sounds a lot less stressful lol.
Mine was modified to provide DBV2 information about how well the adjustment would work, so I only paid for the shipping costs.
