Hello guys,

I own a R56 N18 engine and my DV needs to be replaced. At the moment, my setup is downpipe, intercooler, intake, iridium spark plugs and next month i`m going to remap.

I was looking for ALTA recirculation valve and they say that their product doesn`t work with N18 engine because they don`t have a realible vacuum/boost point and I would have CEL/Limp mode.

After that I moved to Forge one and works the same way, based on vacuum/boost on the intake. How do the forge works and Alta not?

I also researched for the GFB and I heard a lot of problems with lubrification.

What should I do?

The Forge valve still uses the stock actuator, but ties into the vacuum pump for vacuum source. The Alta valve “tricks” the OEM actuator and pulls from the intake manifold. I have the Forge valve on my N18.

 

Good to know. What`s the sound look like? Any vids?

 

No videos. I have a blowoff plate, so it sounds much different than the diverted version.
