Hey all.

Let me start off by saying I have done a lot of reading. And I mean lot of reading about which turbo is right for me.

Basically it has boiled down to me wanting response and a good level of power.

I even found that 13 page long thread about 7/9 5 gtss. It was great for the first couple of posts but then you had to start sorting through the pissing contest the emerged.

So if I only wanted response I would go the -7's and if I only wanted power Id go -5's or bigger.

But the middle point is for me I think.

Now to my question.

Is the 2860-9 equivalent to the HKS GT SS? (I keep getting snippits of people referring to them as equal, or in the same league if you must)

What rpm is full boost achieved?

Is the 300kw range achievable with this turbo?

Thats all I want to know, Unfortunately with my supreme googling powers I could not find a definative answer.

Thanks for any help

Yeah 300-320kw out of both -7/-9 easy, -5 is a good option is u have a rebuilt motor as u can push it harder than u would want with stock

For reference I'm running gtss, full boost by 3800rpm @ 18psi, pulls very linear all the way to the limiter

as per sig and the rb26 turbo upgrade thread is what you want to look through

most of them have dyno plots which shows you the "boost" ramp which is much better than guessing "boost" build rpm

    • You'lll likely have to make do with R33 GTR for engine/tranny stuff, and Stagea for the body. I don't know that there's even been an actual diagram seen in the wild.
    • Haha, i kow right? Could have bought so many cars for the same amount of money (or less) but driving Unicorn gives you at least +1mln to style 😅. Like wise man said "life's to short to drink cheap wine and drive boring cars" 😉
    • Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny
