I am going to buy a boost controller soon. I am wondering what the difference is between the Greddy profec B and the Type S boost controllers. I know the Type S is newer but is it worth the additional money over the profec B. From my understanding the profec B requires a boost line to be connected into the controller (inside the cabin of the car), Does the type S require the same? The profec B looks like it has a really big solenoid, is the type S smaller and faster responding? Just wondering which is the best to get before I spend the money.
Thanks

um i would just get a turboxs manual controler they are much more simple and reliable

My undersnating is that the electronic types are better because they do not bleed (or prematurely open the wategate) until the preset pressure is reached. This means that they can come up to max boost quicker. Also I wanted to have 2 setpoints so the greddy electronic type is a simple version that does this. I have checked into the manual type and have decided to go this route unless I am not undersanding the benefits as I just mentioned.

turboxs all have a ball and spring type valve which doesnt really bleed like the cheapo ones do. also you could always get the turboxs dual stage mbc like ive got, lets you switch between 2 boost levels with a switch inside the car.

i dont think there is really any difference between the older and newer electronic boost controllers other than bling factor. I personally would save the cash and get the older one as long as it has all the features you need.

i have a profec b and a turboxs manual controler and i choosed the turboxs over the greddy cause the greddy was so complicated and very hard to get it set to the boost level your looking for

I ran the Profec B Spec II and now I have the Type S, and I can tell you, the Type S is a dream come true.

The Type S does require boost line inside the cabin as well as the B. The thing is, the early type B controllers are GREAT! If you can get your hands on an older one, do it! Just dont get the B Spec II. Its a peice of ****..

winter39

J-Rat, Yes, I am avoiding the Profec B Spec II for the reasons you have mentioned. I am actually wondering if the Profec B (Old unit) is any slower, larger then the Type S that you have. The solenoid in the Preofec B looks large but then again maybe the type S unit is big too.
Thanks

The solenoid for the type s is smaller then the b.

My profec-b spec II always worked just fine for me. Whats wrong with it?

I hated the complexity of the system, not too mention that in my opinion, it didnt control boost the way I liked. I must not be the only one that complained because they brought back the old style.

OR APEX-1 THEY HAVE THE COMBO TIMER AND CONTROLLER IN ONE

yeah it's complex for sure but it worked fine with my......rrrrrrr, your bnr stage IV 15 low boost, 17 high boost level. There was some bleeding off but we all know that isn't due to the boost controller.

I like my B II. No problems here once I figured it out.

Well if you where any good at reading how to operate a vcr back in the day or nail that 6 botton combo every time durring tekken 3 then you can operate this unit. It takes a little brain power and some attention but surely all the other components in the car including a standalone is much harder to install and understand.

To be honest, when I am trying to tune in excess of 25 PSI, I dont need 6 different settings to be ******* with while trying to tune.

I guess it all boils down to preference, but I hated my Spec II.

I hear ya man, that original profect b I had was easy *** all hell but for some reason I just love digital stuff, lol.

I am considering the relatively new AEM Tru Boost EBC which is a combination digital boost gauge and boost controller. It's supposed to have just a couple buttons built into the gauge to set the boost and be pretty easy to use. I did some searches and most of the Supra guys like them apparently.

winter39

Hmm...that would not be the route I would go. Digital readings of boost or other fluctuating signals would drive me crazy. I like the simplicity and ease of viewing of a traditional gague and arm type readout (I ahve a manual boost gauge as well). I had a Ford probe once that had a digital dash, I hated it about 1 week after owning the car and stopped hating it about 1 day after selling it but to each his own.

i've installed many profec boost controllers and i always prefer the original B series and now the new type S. simplicity = the win.

but personally i'll be using my wolf 3d for boost control
