Well if you set the max boost on the mbc to whatever you had with the n75 hooked it should be alright, right?

 

no

 

opps ya if its the same as teh n75 your ok

 

ok good.. so i should get the kind with 3 ends right? Or is it 2?...., nipples, if you will?

 

well what i did is just take the n75 out all togeather. if you do that you only need the 2 prong one. and this is how you set it up...
turbo nipple----------mbc--------wastegate.
and then you can controle boost o ya the --------=vaccume lines

 

Alright but if you dont have the n75 hooked up, wont that trigger a cel?? What exactly is the reason that most people keep it hooked up?? So If I keep mine plugged in, ill need the three nipple mbc?? I like the looks of ecs's forge mbc's, but i dunno how they perform.

 

^^^I would think you would keep it hooked up just for cel but I don't know yet..................

 

You are correct, keep the n75 plugged in but disconnect its pressure reference to prevent a cel. As for which style of MBC to purchase that will be determined by your budget and your performance goals. The three port MBC is a traditional bleed-type, the adjustment **** controls the size of an orifice, the larger the orifice the more boost is bleed away from reaching the wastegate thereby raising the manifold pressure needed to open the wastegate. One port is an input, one an output, and the third just vents to atmosphere. The dual port is a ball and spring unit, the **** determines preload on the ball retention spring, boost reference is blocked from the wastegate until that preload is overcome. One port is an input from vacuum the other the output to the wastegate. Generally the ball and spring style MBC will have better response and a more stable boost curve.

One caveat, you will be limited to how much boost you can run until you are chipped...
