I am about to replace the turbos on my R33 GTR and i have a choice to make.

I can get R34 N1's through my mechanic for $1495 a piece or i can get GT2860r-7 for $1250 a piece from another retailer.

Which do you think i should go for? I am leaning towards the GT2860's because from what ive read they are the same specs and saving close to $500 is always good.

What are your opinions?

Cheers

Hi mate,

I've installed GT2860r-5, a slightly larger turbo than N1 on my R34 GTR. Works very well and got turbos for same price as GT2860r-7. Was considering HKS GTSS but got garretts for much cheaper and works very well with a good tune. Check the prices on -5 as they were the same for -7s when I got them some 4-5 months ago. No compromise on lag and responses very well on pretty much anywhere on rev range...........now supporting 360+ rwkw.

Yes they are brand new for that price, im not risking second hand turbos.

I have looked at the -5's and have considered them but im really not looking for huge power, i dont think i will ever go over 300 at the very most. The main reason for me replacing my current turbos is because my original ones have major oil seal leaks and need replacing, i have been saving the money for new turbos for a while so saving 500 odd is really good for me.

-5's are 2530 equivs... there is no way they are the same response as factory/-7's/GTSS/R34N1

There most certainly IS a compromise on lag and response compared to the smaller batch

Thats what i was lead to believe.

I am after response over overall power. I am not wanting huge power, i mainly just want my car back on the road :)

I think ill go for the -7's it saves me money and i know they will do the job i want.

There is a black GTR I saw on an igition DVD - which isn't coming to mind right now

but its running N1 turbos on a built motor - 1.7 bar saw it 400kw @ all 4

They upgraded to 2860R turbos (not sure whst specs exactly) now and it makes about 424KW @ all 4

anyways just thought I'd throw that in :whistling:

Hi guys.

I have just done my turbos a couple of months ago on my R32 GTR.

I went for the 2860 -7 with the smaller exhaust housing.

I was told that this was a new smaller housing from Garret to try and reduce lag.

Now, don't shoot me for it because I don't know alot about it.

I know one thing. I was running standard GTR turbos with steel wheels and the difference is huge.

I feel that lag is now non existent which makes it for a real good street car.

I must say that I also installed dump pipes, computer and boost controller so obviously some of the improvements are also due to these extra bits.

Anyway, the car drives really well. The response is quite good.

Power wise, I do realise that power figures varies from place to place but to give you an indication of what was achieved with my current setup, the final power figure on what I believe is a safe tune was 280kw at 1.2 bar.

Anyway, this is my results with I am happy with so I thought that I would share it here.

Turbos ordered :D I went for the -7's mainly for the response etc. I am now a little worried after seeing this thread ( http://www.skylinesaustralia.com/forums/Ga...60-t210071.html ) about my dump pipes. I guess i will find out in a couple of weeks.

You never asked if he changed cams ,has adjustable pulleys or has an after market computer.

But yes........power output is larger with the 2530's and lag is greater.

If you are not wishing to change anything else on the car except for Turbo's you have made the right choice.

      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.
