Hey all

so, i searched, and I know i have seen various threads before with the writeup...

I am running a mbc with the n75 right now, I would like to switch over to just an mbc...

I believe I have to run a vac line in a loop running from-to the n75...

a link or a pictorial would be greatly appreciated

thanx in advance!

 

Keep the N75 or your ECU will go nuts and your car will run like crap. People have enough trouble going to the "race N75" and removing it would be 100x worse.

 

I do not plan to unplug my n75...I plan on plumbing the vac lines to trick it into thinking it is still serving as a boost controller...

I have seen a handful of setups that have ran 100% with a "tricked" n75 and using a mbc for boost regulation...

I know I have seen a pic of the setup I want to run on here somewhere, but my searching is not coming up with what I am looking for...

 

you don't need to run any vac lines to the n75 if your going to use just a mbc.
just keep it electronicly connected. i have mine just electronicly connected and stuffed it near the fender.
my mbc is the only thing connected with vac lines.

found the thread that I was looking for, will update with results, I am going on a 500 mile road trip tomorrow and am going to up the boost...

 

i just left the n75 valve plug in and capped off the vaccum ports with rubber caps i found at work, when i hooked up my mbc like it is in the top pic of that linked thread above
