I searched and read alot of posts about a MBC valve. But when you install it does it eliminate the N75 valve all together or better yet can you run an MBC without an N75? I plan on buying the one from ecstuning.com and it looks as if it completly replaces the N75 valve.

 

Just run the mbc inline with the N75. If not, I'm sure you'll get the dreaded CEL.

 

What you do is find the hose coming from the N75 that leads to the wastegate actuator and split it there. Now, add some new hose to the existing hose, with a vacuum connector, that you just split coming from the N75, leading to the mbc input. Connect a hose from the other port off the mbc to the other half of the split hose connected to the wastegate actuator. That's it.

So recap, N75 to mbc, mbc to wastegate.

 

nope dont use the n75. just got turbo----mbc----wastegate and your set

 

N75 is disconnected, but don't throw it away just leave it pluged in so you don't get a CEL.

The post above is not how I have mine hooked up! It might work like he (ALB6) said but imo he (ALB6) is full of ****.........

 

Yep, that would work.

 

alright so im gonna install the MBC in place of where the N75 vlave was and just leave the N75 plugged in and zip tie it to hold it in place somewhere under the hood

 

You got it.
