are manual boost controller's really safe?

[jrb92se]

92 s13 rb25det swap stock turbo blitz nur spec three inch, ok the car is described above is it safe to use one of those manual boost controllers, also i have a walbro f/p should i get a nismo adjustable fpr its a lil rich ; thanks alot guys

[Joe]

yes MBC's are safe. i run one at 11psi, no problems

and dont touch your fuel pressure. just because it runs rich sometimes dosent mean you should be d!ck with something without being able to monitor the effects (i.e. without a wideband sensor)

[jrb92se]

i had a friend suggest the fpr he said to use a f/p gauge to monitor the pressure though

Just get a decent quality one, mine malfunctioned, i dont know how but i hit 20+ psi a few times.

yea that dosent monitor how the engine is burning

you THINK its running rich, when in all actuallity it could be running fine when you are at wide open throttleagain, unless you have the ability to monitor these things (wideband sensor) dont screw with it.

i was told to use the dna m.b.c by a guy a know he said that he has used them alot and never had a problem

[jrb92se]

i wont mess with the a.f.r next tine i bring it to the shop if they thinks its rich ill let them deal with it

I used the TurboXS standard MBC on my Eclipse and never had a problem with it. The only drawback to them is they don't have a set screw.

I want to say Hallman makes a pretty kick *** one that a lot of the DSM guys use, but I am sure it could be taylored to fit an RB. They have locking nuts on the adjusters, and from the feedback I used to read, their boostspike is pretty much nil.

MBC's will do that... correct me if i'm wrong but they have a tendency to have both boost creep and boost spikes. you can set it for 15psi and every once and a while it will spike to 17 or even 20 a lot of the reason why people get EBC's is so that they can adjust it from inside the cabin, and cus they're fully adjustable. you can adjust an MBC in the cabin but you'll run a ish load of vacuum line and i've heard that it will lessen your boost response?? but with a EBC you can adjust stuff like gain and hold so you can eliminate the issues you'd have with boost creep and spikes.like i said dont know if thats all right so dont take it to heart, just throwin my two cents in

I use a hallman Pro series on my 25, and yes it kicks ***, holds boost amazingling! i get full 10 psi by 2700 and it holds all the way to redline. cost me $115

Mine took a **** at the best time merging in early morining traffic, meanest compressor surge ive ever heard, but the wheel held up like a champ!

[jrb92se]

the main reason i was think mbc was cost but if im going to run into issues that could possibly blow my $9000 enigine up i think i will wait save the extra money and get a ebc. which ebc would you guy recommend; i was told greddy b spec or something i forgot ?

[lucky7]

i have an APEXi AVC-R. havnt even taken the thing out of the box yet. but from what i understand, you can run staged boost with it. so in the future, it will help with traction when launching. i paid $383.40 for it, new.

I paid $55 for my Hallman mbc, and have had NO issues whatsoever. I guess if you have the money for an electronics one go ahead, but I would rather put that money elsewhere.

[Joe]

i paid $6 for mine.

home depot build-it-yourself.

[rb240det]

Yeah I built one myself a while ago...but had a few problems with it. So I just forked out the money for one that was proven. But $6...that's pretty good...I thought I was doing well with a $11 budget.

[Gold Digger]

Actually, if anyone knows where I can get a Hallman that is adjustable from the cockpit for a decent price, let me know. I'm gonna be in the market for one this winter or so.

[rb240det]

I got my Hallman from Horsepowerfreaks.com, but I don't really remember how their prices where on the cockpit adjustable mbc's. Might be worth checking out.

Ill agree with kamin in a big way on the fuel pressure regulator on this one.

I had a megan pressure regulator that somehow the bolt that retains the spring on it to adjust the pressure on top got loose, and instead of running about 40-44 psi, it somehow managed to get up to 80 psi at idle, luckily i caught it and fixed it, but im slapping the stock pressure regulator back on tommaro, and then the FPR will go in with a wideband later.

[jrb92se]

how can you make your own mbc? never mind ill search but sounds interesting , also i was think a nismo fpr but im just gonna pass on it for now i need to fix my front suspension

finding a good spring is hard for that, if you can get a good one, your set, if not your controller with suck.

im gonna come off like a d!ck but i have to say it

thats because you bought a megan racing fuel pressure regulator.

cheap, reliable, fast. you can only have 2. I have a nismo FPR and its never lost its setting.

very true! try to get one that will hold up to temprature too!

[jrb92se]

ok i decided last minute today to go ahead and buy th d.na. motorsports mbc i got it put on at xat the car is allottt faster and they only turned it up to 10 psi. im gonna hook up my boost gauge tomorrow can someone please post a link to a thread thatll help with the boost gauge install id search but im going out to dinner and wont be home til late thanks
