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

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.

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

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah 路 Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline 路 Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz 路 Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
