Hi guys,

Finally got some decent pics of my bros turbo of his 1995 series 2 r33 gts25t...

If you know what type of turbo this is please let me kow and how much boost can i run?

also just wondering why the exhaust side looks rusty colour ?

is that maby because of af mixture ?

just some info on it, the turbo spools up at about 4000 and full boost at about 4,500 , 5000 rpm

cheers.

It looks like the standard turbo to me, with plastic compressor wheel and ceramic turbine wheel. Not sure what that orange stuff is, I've heard of some people getting orange plugs from some 98RON fuel and too-cold plugs, maybe it's related. They all get brown-rusty on the outside, but that's the first one I've seen that was orange on the inside.

I dont think the compressor wheel looks std, but the turbine and housing all look pretty std.

I havent seen all that many Nisan turbos off the engine so cant be sure if the compressor isnt factory, just those that i have seen look different.

As for the colour on the exh. housing, i suspect thats from running some sort of jungle juice, be it from additives like Octane booster or toluene or from Shell 100 racing fuel etc. I hear if its white then its from the A/F leaning out, so its not that.

ok,

also on the back it says T459 ? if thats related to anything... and the number 1 so i was thinking its stage 1 upgrade?

And i'v ran 15 psi before no worries,

but it doesn seem like standard turbo because after it hits full boost it keeps pulling all the way to redline and doesnt slak off..

is it bad for the turbo and car to run octane booster? cause i have before....

    • 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. 
    • 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.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • 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
    • 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.
