Looking at MBCs.. quick Q

This site may earn a commission from merchant affiliate links, including eBay, Amazon, and others.

Im confused on what you mean "inside". It will allow you to raise and lower boost. I would buy a real MBC some of these ebay ones are crap.

There is nothing wrong with buying a MBC on ebay. I know many people who are running a VooDoo MBC purchased on ebay with great results. I think it costs around $15 shipped.

Does mounting it inside cause any performance loss or problems? This is the one Im looking at

I've never had a cabin mounted MBC, but it shouldn't cause you any problems. I know Hallman now offers a MBC that you can mount inside your car. Hallman Evolution MBC

In all honesty, it doesn't matter if it costs $6 or $60 all MBC's work about the same. Your biggest concern is you want to get a ball-spring type valve. Other than that, your set.
 
If you are a diy er you can make one for about $10.00 in parts from home depot. I cant remember if it was here or vfaq that had the info. I will try to find out and post back. I built mine and it works great. Travis

Yeah I have already read up on that... In all honesty.. I dont trust myseld enough to make one, not that Im a complete retard or anything, its just I wouldnt mind spending $60 on something that if I went and F'ed it up it could possibly blow my engine, ya know? I just do dumb shit. When I had my 300 zx and did the suspension, I screwed up and put the rubber grommets in the wrong spot on the rear.. when I took it for the first drive it bounced like like a god damned pogo stick.. I knew what it was right away, only b/c Im not a total retard, but I still do dumb shit. So ill pay $60 for a MBC. I still want to get my moneys worth tho. Thanks everyone for your response! :thumb: :rocks:
 
In response to the oringinal question, yes mounting in the cabin can cause problems if you run long vacuum lines to do so. With the Hallman MBC the vacuum lines stay short so it works fine, however the ebay one on the link looks like it will require a few feet of hose to make it work, which in turn will cause a major delay in response.
 
I went and test drove a Ford Thunderbird Turbo Coupe before I got my talon. The guy had a gillis mbc and had it inside his car. He he had no issues out of it at all. We were riding and he could adjust the boost as we were driving, without a problem.
 
if you want the mbc in the cab why not just get an EBC?

Why are people paying 40+ for their mbc's?! Igot mine for 15$ :)

I had a voodoo and it didnt even work, I pulled it apart and damn are they cheap. The spring was broken. You can build a better MBC for cheaper than $15. You can buy a used real MBC for a under $50.
 
I know from personal experience that longer boost/vacuum lines can cause spike. I moved my MBC to right at my J-pipe and it was an unbelievable improvement, also started doing hard piping with brake line(no real reason, just because i can and am very bored)
