Hey guys,

just bought a profec b 2 boost controller and installed it yesterday.

just need to know what to do with the vac line that went from the stock solenoid to the black pipe

that comes from the recirculation valve.

do i just block it off? what's it for?

any help would be appreciated.

cheers

doobs

Actually, dynos are no use really for setting boost controls as they don't provide real world conditions and take alot of time and therefore money to get it anywhere near tuned for the road. You would be better to go to a quiet road and sit in the passenger seat and get your friend to load it up, each time tweaking the settings.

And yeah just block off that vac line, I put a screw in it that was slightly too big so it is tight, then i sealed it with silicone and doubled the hose back on itself and cable tied it near the crimp.

Hope that helps

If your a dumb arse, you might want to get somebody else to tune it, u can stand on the side of the road with one of those old school grid iron helmets on, watching lol. Just kidding mate, I tried doing it on my own once when I first got it, NOT a good idea. Possible the dumbest thing I have ever done in fact, I almost had a head on! I was just sooooooo sooooooooooo lucky the other driver wasn't some dumb idiot like me , but then again you don't expect traffic at 4 am on a week night in an industrial area.

Fair point ardie. i might just wear an icecream container on my head instead,

it's not like i've got much to protect. hehe

i got a mate who's looking to get a profec for his GTI-R so

he can help.

lol. nah i've been using the peak and last boost screen to help me tune it.

BAHAHAHA ice cream container, thats gold, so using that on the misses next time she does something stupid.

As for using peak and last, you wont be able to track how the solenoid reacts throughout the rev range and to the various boost loadings. I've installed and helped set up 6 or so of these including whacking one on a 380awkw GTR and every time I do it the same way: late night, industrial area and friend booting it while I tweak it.

Also, just out of curiosity, where are you getting the boost lines from?

If your mates looking at getting one, I'm going to have one come into my possession within the next couple weeks, if interested in it let me know

    • So could it be assumed it has been installed intentionally with potentially a power FC boost controller kit? 
    • Had my rig on Matt's dyno at PITS the other day. After a few years between tunes I added a few sensors and swapped intercoolers. Result. 553hp at 26psi. Not bad for an FJ20 that was built in 2007. The problem.. It filled the overflow bottle on hard runs which leads me to believe the head gasket isn't sealing. I have a coolant pressure sensor which was reading cap pressure at 22psi and occasionally overrunning to 23/24 psi on deceleration after a pull. It was not spiking. It has arp2000 head studs and a cometic gasket. As its been 18 years in service, I pulled the engine out and head off. Everything looks good but we obviously have an issue. Where I'm at.. Years ago I had the same issue, I checked the stud tension and they were all over the place. Some at 60 to 70 and some up near 90. I nipped them all to 100ft lbs and this stopped the water push until now. I believe this compromised the gasket back then. What do I do? 2 options are..  1) I bought arp 625+s, which I could put in with a new gasket. Thinking Kameari this time, reassemble and try again. 2) strip the block, get fire rings machined in with copper gasket and try that. I do not want to push it more than 28 to 30psi. I think the turbo will be out by then anyway. (G30-770). My other concern is the long term ability of a copper head gasket. Are they streetable for years? I feel like a new gasket with the new studs will probably suffice, but I don't know. Any thoughts welcome and advice on copper gaskets and fire rings. Thanks!
    • I'm a fan of the JZX110, and the Aristo. Big cruiser cars, and with the factory cars, super comfortable and feel like you're driving an armchair! And the JZ motors are a pretty nice engine too, especially with some basic mods.   The import process, and the need to be able to trust people, and the fact there's so many scammers around is what ever puts me off wanting to go through that ordeal!
    • I don't care for these at all, but at least the underside looks straight and not rusty. A good basis for a long life. Many cars from Japan have been lifted with forklifts and f**ked almost irrepairably.
    • Yes, but it's not dumb or dodgy. You can build a perfectly good boost controller from a pressure reg, a relief valve (looks same same as a reg if all from Norgren or SMC, for example) and a check valve. I ran one for years. Only superceded with  EBC because I could get one for cheaps and wanted finer control.   THis mod is certainly not a sketchy boost mod, provided the boost is kept below the "spin to death" threshold of the turbos.
