R34 Question

[R34P3R]

this may be a stupid question but my friends and i was wondering how much psi does a stock r34 run on? i tried looking it but but just got alot of car reviews that talked about crap

[hoony]

seven pounds - (7psi)

EDIT: ELEVEN POUNDS!?!?!

well i don't know then bahaha

eleven pounds - (11psi)

point seven of a bar - (0.7bar)

same as a 32gtr - (same as a 32gtr)

[SKYRYAN]

An R34 GTT or an R34 GTR?

[infamous_t]

Not this again, Stock gauge doesn't read in bar, it reads in torr (mmHg)

6(x100 mmHg) on the stock guage is actually 600torr(mmHg) = 0.8bar = 11.6psi

That said I don't know what boost the GTT runs

[hoony]

i think it's 7psi LOL

[infamous_t]

Found it, R34 GTT Stock boost is 7psi, just under 0.5 bar.

R34 GTR is same as 32/33 GTR... which is what Topaz was referring to I believe.

[Marco-R34GTT]

GT-T is deft 7 PSI

[NISZILA]

Well... if you want to get technical, it runs a two stage boost. First 5 psi and then up to 7psi at higher revs. You can earth the one wire and make it 7 psi all the time though. This is the same for the R33. R32's run 10 psi.

Just to clarify, I'm talking about GTT's, GTSt's here... not GTR's

[R34P3R]

yes i meant a gtt and thanks for your replies

Wow, I really thought the GTT's were 11psi like the 32GTR's. 7psi is shit!

Not sure what 33GTR's are stock, 34GTR's are 1bar stock.............................. I'm 95% sure

It can be 11psi... Easy fix

[lcy]

i am running 0.85 bar(12 psi) daily.... izit bad then?? lol

That changes when you get the RB20 actuator yeah??

10 psi???

You're doing that to your car aye??

12 psi will be fine, but you may want to check that its not leaning out at all. Upgrading your fuel pump is always a good idea when running more boost. Probably wouldn't go too much higher than that until you have some other bits and pieces to support it.

Yep thats right Cause the R32's are 2 litres, they run 10 psi to make up for the smaller capacity. By changing to the RB20 wastegate actuator, you are getting 10 psi instead of 7 psi. This is a lot better than a boost controller as there is no chance of boost spikes, therefore safer for your turbo. You still need to ground that one wire to get rid of the two stage boost, and then bypass the solenoid. There is a tutorial somewhere here on SAU

Link??

So with the actuator you don't need a boost controller??

Here you go Mark

clicky

With the actuator you don't need a boost controller. This is how it works

First, ground the one wire mentioned in the tutorial. This will change it to constant high boost mode meaning istead of a two stage boost of 5 psi then 7 psi above 4500 rpm, you are running 7 psi all the time.

If you put the RB20 wastegate actuator in and bypass the solinoid, you now have 10 psi all the time. You have to bypass the solinoid cause it will limit you to 7 psi. The solinoid is what is used to create the two stage boost. Since you are not running a two stage boost anymore, you don't need it
