Leigh,

You and Andrew probably have the OEM boost restricter removed, which inside the hose that goes to the Boost Solenoid.

Once removed you can run a "Safe" factory boost increase, as what I have heard and read about so far.

i hope r34 gtr turbos can run a bit more boost safer than the r33 and r32 gtr's because mine usually runs over 1bar, the highest it got to was 1.18 on the screen which was right on the edge of the screen, maximum it reads is 2.0. in psi i think its roughly 16-17psi.

Not really - they are just newer, doesnt mean they wont/cant fail in the same fashion especially considering you dont know what was going on before you got it.

too much heat = bye bye turbo.

could happen to near new turbos IMO

I know everyone will say that it is way to much boost but I have never seen an R34 including mine run less boost than that. I bought mine with only a cat back and am in fact now running less boost with the computer and full exhaust. Factory mine ran the same and I know of a few other guys telling me the same, when mine was stock it used to hit 1.18 bar as well on occasion. Now with the wolf I have managed to run a perfectly steady .9 bar.

So done stress, the R34's just run more boost than the R33 and R34. In fact it may just be coincidence for me but I have never seen a 34 do anything but run minimum 1 bar.

Geoff brought snowys old factory turbos - i think he got like 1,000kms out of them or something before they let go and took his motor with them (this is going back a few years now)

So they can indeed fail... It's just that most R34 GTR owners dont run them that high, for that long.

I think we will see more examples as time goes on of this occuring.

+1. How long do you run that 1bar? If you're just driving on the street it wouldnt be that long would it? If you're doing mountain runs/track, the risk just increases. Its all about whether or not you wanna take the risk.

Nobody really say you cannot run 1bar but rather its not advisable to run 1 bar because the risk or probability of the turbo blowing up increases.

Mine runs 1-1.2 bar factory with no dramas but I need a tune.

Mate you've got a NUR (according to your profile/nick). They have N1 spec turbos like mine so you're not comparing apples with apple. I'm running mine at 1.15bar with no dramas too... -.-;

with my BNR34:

Mods

-full exhaust system

-cam gears

-power fc

-kn panel filter

everything else standard, 1st dyno tune from Race Pace 280awkw (30,000km) 4 years ago. Now with (120,000km) dyno tune from Race Pace it's now 250awkw.

Not to sound rude but how did Racepace dyno your car all wheel? They only have a rear wheel dyno...so they can only generate numbers with rwkw...did they ever have a 4 wheel dyno before?..

Trent has a rwd dyno, and when i asked him about it he said he can put a "GTR setting" on or something which puts 5% more stress on it or something to act like a AWD dyno when doing GTRs, something along those lines anyway he can probably explain it more hehe

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...

      the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
