I just recently went single and had a Greddy Profec B with the 3 dials, that came with the car and worked great for the sequential twins, but i would like to have something more on the terms of display where i can adjust the PSI and see the actual Number i am adjusting, rather than guessing what min and max is in terms of PSI on the gauge!!!

So seeing if you guys could recommend me something and possible tell me what features you like the most!!!

Thanks....

I'm running a profeb b with a 12 psi spring and in this cold weather with the 'low boost' **** on the minimum I'm seeing 14 to 15 psi. compare that to my old setup with parallel BNRs, I'd need to have the low boost **** all the way to the max to see about 14-15 psi.

Honestly, I think the profec b is a pretty damn good boost controller. My parallel BNRs were akin to a medium sized single, and it gave very consistent boost, it would only change given extremes of intake temps.

If I were to change to something newer, I'd probably go with the most recent blitz dual solenoid offering. Some good reading here, somebody just posted this up:

btw, you did remember to change your dip switches on the back of the profec right? internal and external wg have different settings.

Interesting, I will definetly read up on this, and thanks for the FYI, I completely forgot about the pin switched...lol...But my car hasn't run in the past 2-3months...lol

Be careful, I saw 23 psi (!) which is what sent me looking for answers. That was my problem.....thank God for water injection! I was running 93 octane at the time. The car was fast as **** until the tires broke loose

This is the orientation you want for the dip switches with an external wg:

4-down
3-up
2-down
1-up

look into a hallman pro controller as well. Its manual, and alot cheaper. Though you may be looking for quick settings. If your like me, I just set it, and done

Blitz DSBC is what i've heard to be the best. however, i used the Profec B Spec II and never had any issues with it. i will be using it again whenever i get another turbocharged car.

Are you sure, I am pretty sure that the profec B was, but double check Greddy's website

you're correct, actually we're both correct. I gave the orientation for the 'overboost' setting for an external wg. Basically, I didn't want to deal with having unstable boost, so used the overboost setting.

Gotcha, just to catch you up Rich,
I also found another tranny, bought it off of Brian Galloway (Japan2LA)
it has a bad 5th gear synchro, blocker ring was broken(I will fix it) Anyway, he said he would sell me another jdm tranny for less cost and no shipping, well there was a delay with shipping as the trucking company didnt pick it up on this past monday per him saying that he scheduled the pick up, but they never came. Now on thursday night he said he had the tranny on a pallet in his vehicle and would drop it off in the AM Friday direct to the shipping port, and would send me the PRO number THAT day after 5 pm his time (CA)...well havent seen one yet, said he would email it to me...payment has been made. Hopefully it will be a good tranny this time and I will get my PRO number tomorrow to verify it has been shipped, if not, gonna have to contact some people.

Wow, that sounds familiar!

Japan2LA sold me some parts for my rebuild (1 housing and 2 rotors). After the parts didn't show up for 3 weeks, I asked him where the hell my parts were. He said he 'forgot', and would ship them out the next morning UPS 2-day and send me the tracking number. 2 days later I had no parts and no tracking number, so I decided to file a complaint with Paypal.

He e-mailed me, telling me he was very sorry and that he would refund me and send the parts for free. Well I got my money back, but I sure as hell never saw any parts. He claims he didn't get any of my e-mails and that he had already 'moved on' from our previous transaction and had nothing left to discuss.

I told people to steer clear of him in the For Sale forum whenever he'd pop in and try to peddle his wares. He sent me the following PM:

Subject: You are a little BITCH
Body: I read what you wrote.. i guess you are angry because I resended my offer to give you the parts for free... Anyway, keep it up I will be in Texas Next month...

Yeah, very professional attitude.

Had the HKS EVC IV with no problems, now I have the GReddy Profec-B II with no problems either.

BLitzed33

Sorry for the off topic posts, but I just requested my money back and he did refund me my money and also covered the cost of the synchro/blocker ring part.
I think he needs to reorganize his time management and have a better system of what, who, and when and get things done, thats all.

Thanks for the replies guys!!!

On another note, why does the original Profec B has a large Solenoid box, as compared to the newer Type II and Type A???

And yes its gonna be a good idea to set mine up to on/off/on/off for external wastegate and overboost protection...

And Rich, the instructions advise to connect one side of to the Vacuum/Boost on the Intake manifold and the other to the top of the Wastegate... and the side of the wastegate to the intake manifold Vac/Boost as well???

Can i still use the nipple outlets from the Lower intake manifolf for boost/vac purposes, pic attached??? I see some Single guys cap those off and some leave them alone, makes no sence, Wouldn't there be a leak>>>

BLitzed33

You can use the one that is a pass through to the lower intake on the inside to a vaccum source...and no there would not be a leak, because the others are just pass throughs to nothing. The earlier profec B's used TWO solenoids while the newer versions use a single solenoid.

You connect a vaccum/boost source to the controller and tee that to the in on the solenoid, and the out to the side of the wastegate, and also a seperate vaccum/boost source to the top of the wastegate, at least thats how I did my Greddy Type S (newer version of profec B). I have mine on up down down up as my Electromotive TEC3R has a overboost cut function.

Use the greddy profec b instructions on their webpage, look at the 4th page down for install instructions for an external wg:

http://www.greddy.com/img/PHP/products/pdf/687.pdf

For the 'IN' nipple on the solenoid, run a line to a boost/pressure source (I used a 1/8npt nipple on the pipe right off my compressor) and T that with a line to the side of the wg. For the 'OUT' nipple on the solenoid, run a line to the top of the wg.

In this larger version of my current sig picture, you can see the boost/vac source I used, the solenoid is tucked in by the ABS in the pass rear corner of the engine bay. You can't see the wg lines, they are both s/s and run from the solenoid down to the wg. I used some monster zip ties to snug the lines on the subframe to keep them away from the manifold runners.

Yeah I downloaded those instructions, which is why i am a little confused, per the diagram, its shows that OUT is going to the top of the wastegate and the IN is going to the intake manifold a Boost/Vacuum Source, and the side of the wastegate is goin to the intake manifold as well (Boost/Vacuum Source) and what i've seen others do with other brand of boost controllers is run one line from the Boost controller solenoid to the Compressor (Boost/Pressure Source) and the other to the top of the wastegate, and i think the side of the wastegate was connected to the Compressor (Boost/Pressure Source) as well. Is the diagram wrong than???

Id say either Blitz SBC or Apexi ............as long as it is closed loop

I use a Blitz SBC IDII....... works awsome, kind of expensive

I will be trying the closed loop boost control on my Haltech E8 though........

I've been very happy with my (optional) Apexi boost control kit working off of my PFC. It's allways right on at WOT. Never any creep nor any spikes. It may not be as fancy as Blitz SBCID (single solenoid vs dual) but it's just as acurate without any wire splicing or aditional parts to stuff in the cabin under the dash or wherever.

I'm not sure about how other people do it, but I can tell you this---I hooked it up as per the Greddy instructions for the Profec B (as I described up above) and the car boosts perfectly.

Max_Spd

iTrader: (78)

Rich, the only problem im having is that the instructions are saying to run the lines to a Boost/Vacuum source on the intake manifold and not the Boost/Pressure source on the compressor/piping!!!

GoodfellaFD3S

iTrader: (213)

That part doesn't matter, it's up to you. Sourcing it from the intake mani is the same as sourcing it from the comp charge piping----just further downstream. As you can see from the above pic I posted, sourcing it just after the compressor works fine. As a matter of fact, that's how Gotham sets up all the single turbo FDs that leave the shop.

i liked my e-01... has a built in digital boost gauge, also can display 3 variables at one time... like boost, egt, and wideband 02

Max_Spd

Nice controller, but a bit $$$ Much...lol

So if i were to hook up my Greddy Profec B like in the attached pic, it should work great!!! and also doesnt the overboost settings on the back of the controller (on/off/on/off) make the boost a little more slower to make sure that no creeping/spiking will occur???

GoodfellaFD3S

iTrader: (213)

That's a good question, I'm not sure. I have been thinking about switching to the 'normal' external wg settings to see if there is a difference in spool time. Although, the controller does have the 'balance' **** which should deal with the response/spiking you speak of, and shouldnt have any effect on creep.
