Ok i'll try explain this as best as possible, and hopefully someone will know that im talking about.

Basically, the 2nd turbo intake pipe, inbetween the AFM and turbo, that pipe is sucking shut right where the springs are. I have T517z Turbos i only just upgraded to about 2 months ago. I had the heat sheilds off for about a month and a half, and i had to change the 02 sensors, but i didnt pull anything apart i just used a screw driver and pried the pipe away. I think when i did this i may have damaged a spring or moved it aswell as the heat. I played around with it one day when i put the heat sheilds back on. It hit 1 bar of boost for about 5 seconds then cut back down to .7 to .5. It variates. I was wondering if anyone has fixed this before, or should i just make up some new intake pipes?? I was gonna weld up some bigger alloy pipes at work because i still have to fit my Z32 afms. But if i could fix the standard pipe, i would much prefer that. So if anyone out there has fixed this. Please help me! Hope someone understands what im talkin about too.

Cheers

A quick fix is to secure cable ties into the ribs on the hose. This helps stop the hose collapsing because it actually expands slightly in order to collapse and kink. It may take a couple of dozen to do so, but if it doesn't work you are only out of pocket a couple of bucks.

I was about to suggest that! That or big metal hose-clamps, cause they are harder to distort than cable ties.

In any case, it'd be a quick fix type thing that I wouldn't leave in place... change the pipes over, but remember that the motor needs som flex in all the piping, so it might not be a good idea to have all steel piping. Buy some of that blue/purple rigid silicone piping or something.

either what was said above or buy a aftermarket induction pipe set, or what i did was buy 3" mild steel elbow from exhaust place, trial fit and hack saw. Then also cut the rubber pipe nearer the turbo and insert the steel pipe and clamp her in tight - no way itll collapse

      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.
