Rb26 Turbos

[stasis]

Guys ive got a Rb26 stock std. I just want to know the ctock turbos is it ceramic or ball bearing type ones? thanks

[Duncan]

Ceramic blades, plain bearing. Shouldn't really boost over 14psi

[wrxhoon]

As Duncan said but R34 turbos are ball bearing .

[stasis]

ok thanks guys

[stasis]

do you guys know whats the stock standard boost?

[Duncan]

Standard boost is 0.8bar per the 32 workshop manual.

THanks duncan. So preety much the turbos are already at their 80% limit then.

I was chatting with hypertek las week and i told them i want an everday driveable car with at least 250kw@wheels. Ohh I dont think i mentioned this the car ive got is the 260rs. I just got the car not long ago thats why im asking all these basic questions. Pardon me.

Anyway they said the power i want is achiveable only with the following parts :

1. Full echaust system. Currently i have everything fitted except for the extractors (looking for 1 and 3 : Dump pipes) the rest of the exhaust is 3" as well.

2. adjustable cam gears. ( In transit)

3. Drop in k&N filter

4. Power FC with boost controller.

5. HD clutch.

6. Higher boosy didnt specify at what pressure.

This will roughly get me there. The main problem is are the urbos. The std turbos are ceramic which i need to change to a ball bearing type with metal fan. So i though about it since im goin to take out the turbos when i fit the dump pipes and the extractors might as well change the tubos as well.

Now i dont want to mess with having to change the fuel pump and injectors , water pump upgrades and oil pump ungrades. So i was just thinking of geeting a R34 GTR's stock std turbos whack it in and run a higher boost.

Will the R34Gtr's turbos bolt on directly onto the the 260rs? How much more boost can i gain from it? What other type of turbos will fit onto my car? Like a r32 N1 turbos?

Finall thing where can i get a specifications for the different turbos ever made for skylines? What which model is interchangeable to which? Like an an example which turbos will fit my 260rs? And the specs for it/

Thanks for the help guys.

Cheers,

Yudy

yeah look turbos are going to be a problem getting to 250 injectors, fuel pump and and afm will be close to their limit but OK with a safe tune if they are healthy.

I'm pretty sure all of the stock turbos are going to fall short of 250, 32 (or later) n1 can make it, or hks gtss, high flow standard etc etc

Unfortunately I am not sure about the 260rs engine bay, although I'll be interested to see how you go for a future project As far as GTRs go all models take all the same turbos, there are heaps of low mount standard manifold options, but highflow standard would be the cheapest if thats all you want.

260RS ....the same motor as the GTR in that year.....What year is it...?

If you have a 98 and up they are the BB type.

If you have the ceramic...

GO

air mods,exhaust mods,computer and boost controller,N1 gtr(300Hp each turbo's)

This should get you to that figure.

But after you get use to the power you will not be able to push these turbo's much further

Sorry guys been busy these couple of days.

Well i forgot to tell you guys its an S1 98 model. i have been told that the stock turbos are steel not ceramic and i can run with it. with bosst to up about 1.4 bar. I dont know the durability factors on the turbos if ran at that boost.

So heres the current ides . im not looking for big powers if not i will get too michevious with it. If you guys know what i mean. Itchy feet and feeling heacy footed too!!.

Anyway heres the list :

1 Power Fc w/ boost controller. (either Apex ones or the HKs v pro

2. AFMs

Will suck it and see how much power i can get. I have been under the guidance of a friend of mine who recommends me what to do. Cos i got the same car as his

But im itching to get the R34 N1 turbos but to think about it if i get the N1 turbos i will probably need to upgrade the fuel pump, fuel reg and injectors. But i think i will wait But wat do you guys think?.

Hello again.

If you like them buy them, don't get petty with information.

Just look at the results people are getting on stock bits and after-market turbo's.RB 26 Turbo upgrades.

You will find you can get these results easy without injector or fuel pump upgrades.

A goodtune and computer with great air flow(INTAKE and Exhaust)

You could sell the turbo's you have, and get some N1's if you like.

With a car like yours you should do the Turbo's.

I have a set if you like i could sell you them...They are Garrett and are bolt on/no modes.

New in a box.

PM me if you would like them.

Cheers
