It would depend on your level of mods.. if it's capable of flowing enough to make 7psi lower in the rev range, then yes - you would feel the difference. Otherwise a restrictive exhaust would probably make it impossible to make any more boost than 5psi up to 3500rpm.

edit - reports from that thread just posted say that yeah you do in fact feel the difference. I guess a thread wouldnt have been made about it otherwise :thumbsup:

asking a stupid question: do you notice the difference if you put it up to 7psi all the time? (EBC or other ways)

Yep your fuel consumption goes up :thumbsup: Well it did for me. But in terms of performance, you do notice it right off the line. It's only for a split second or so before you get over the 3500rpm line.. but you can see it more clearly on a dyno. With mine.. on the dyno you see a distinct spike with the dual stage, and it's flatter with it disabled.

so tred: I bought the $22 (cost more than that now) boost controller to achieve 7psi. I beleive the stock solanoid constantly "bleeds" some pressure out to the wastegate, so it takes a bit longer to build it up.

Using the manual "ball and spring" controller made a HUGE difference for me. No extra fuel usage, but much more stable and constant boost. I ran 7psi with a completely stock setup, and i'm now running 8psi with just a split dump and 3" cat.

It's a "must do" thing, I beleive.

      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 · 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.

      By cosline · 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 · 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.
