Highest Safe Boost For My Stock Rb26?

[Purchase]

Hey guys how high can I put the boost on my 32 Gtr it's mainly stock just bigger intercooler and cat back exhaust it's at 8 psi ATM which I take is stock? Just want an idea if I can safely boost it more than that cheers

[Anfanee]

Don't go higher than 12 PSI. Also get a standard 32 GTR intercooler. They are actually one of the best before spending big bucks.

I already bought a bigger intercooler and put it On would that matter?

[Hadouken]

I would just run 25 psi and not listen to these yellow bellied cowards.

Bigger intercooler means bigger boost no?

[Anfanee]

the GTR intercooler is good to power bands upwards of 600HP.

[pistol-pete]

12 is stock (well a touch over like 1psi)

[niZmO_Man]

Go to driver's side strut tower, locate the boost solenoid (small tube looking thing), pull the whose off with a white band on it, squish it, it should feel hard (piece of plastic in there), cut that bit off (so you remove the white band/plastic restricter thing), put the hose back on, enjoy 12psi.

How much boost have people been running on stock 26 with E85 (-5's and head gasket)?

[Purchase]

So if I run 12 psi is that pretty safe still? Being stock bar big intercooler

[usmair]

we've put 30psi through a stock block on e85... still going strong!

[OVA 300]

Without knowing the condition of the 20 year old standard turbos, I wouldn't suggest anything over 12 psi unless you WANT to blow the turbos. Keep it sensible until you are ready to upgrade them.

Wasn't planning going to High just wanted to know a safe psi level on all stock want it reliable still

[Hadouken]

Then get rid of the crramic turbos and run stock boost. Most reliable skyline ever

[Purchase]

As the topic states I wanted to know if it was safe to run higher boost on stock turbos and if it were what can I go to without a problem....

Stock boost for the R32 GTR is around 0.7 Bar = 10.9 Psi.

Well that's what mine ran at.

If you don't know the condition of the stock turbos don't run anything above 0.8 Bar = 12 Psi.

​Just in regards to your bigger front mount intercooler, you were better off spending the money on Down and Front Pipes with a High Flow Cat.

Giving your GTR a full exhaust upgrade will benefit you more at this stage, if you just want to keep it stock-ish...

Stock GTR front mount intercooler can handle 300+ kW's.

But anyway, all for the better in the long run.

Sorry to butt in. On the subject of stock engine and boost, I'm running a very healthy R33 Rb in my 32-r and I'll upgrade to N1 steal wheels with ceramic coatING on the hot side, what's a good boost for me while still being on the safe side?

What N1 turbos you getting?

From memory they came from factory running about 1 Bar = 14.7 Psi.

(R32 GTR Nismo & N1 / R33 GTR N1 / R34 GTR V-Spec N1 & V-Spec II N1 / V-Spec II Nur / M-Spec Nur)

You could run a tad higher 1.1 Bar = 15.9 Psi / 1.2 Bar = 17.4 Psi.

My GTR has the R33 N1s and I have been running 22psi on them for the last 2 years on E85. I think I have stock bottom end. I don't drive it at that boost all day if that helps
