Bleed valve on a 33GTR

My car currently had just a catback exhaust and pods, with the boost restrictor removed.

I just had hks 2540's and dump pipes fitted, and ive got a pfc ready to be tuned but waiting on some cam gears to arrive first.

the car used to make 1bar with the factory turbos, now it only makes about .7/.8bar and takes a real long time to make boost (I know the 2540's are laggy but I think this is taking longer then it should)

I went down and bought a simple bleed valve hoping to get a harder boost curve (least come on boost quicker) and maybe raise it back to 1bar, is this a good idea?

Is there any chance of maxing out the injectors or running too rich at this stage at 1 bar with these turbos?

Anyway how do you install the bleed valve into these engines, my mechanic said it wouldnt work plumbing it into the hose that had the restrictor and talked about pluming it into a thin metal pipe on the turbo side as he said that would control both turbos

Is he right or is he making it seem harder then it really is to install this thing

Thanks in advance :headspin:

The factory hoses are very hard to get access to.

The easiest way to do it is to block all of the old hoses and run new hoses from the intake manifold through the bleed valve, to a tee junction and then to each wastegate actuator. This keeps the hoses nice and short too.

Yeah just get a crappy bleed valve for now, shit i cant even afford a boost controller yet and im running 1.2Bars on the GTS-T also with a GT-2540. Dont know what you mean by laggy, the mechanic when i had it on the dyno said it kiked in very early.

      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.

      R32 gtr transmission strength, billet plate

      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.
