Ok, heres the story, i went and had a chat to a tuner about getting my PFC tuned and what boost to run etc! He said that some of his customers have run 15psi through their stock R33 turbo... I have read on this forum that most of you say that around 12psi is the limit or safe boost for the stock R33 turbo. So is this tuner trying to provoke blowing of turbo's to get more business or can 15psi be done?

12 is about max, maybe 14 if it was tuned correctly (or if it was on a rb20), but you still wouldnt be looking at much life, 15 psi is just to high for a ceramic turbo

hope that helps

ok what everyone is tryin to say buy 12 psi max is that will keep the turbo in a healthy state runnin 15 psi will work but dramatically shortin the lifespan of your turbo due to the ceramic wheel so if you wanna run the risk of blowin your turbo in a couple of months run 15 otherwise if you wanna keep your baby runnin smooth for a while stick wid 12psi but i guess you could always upgrade turbo if it blows :(

more boost only means more power when you are in the effiency zone of the compressor (known as island).

the compressor map will tell you when this stops.

for the stock compressor, past 12psi dials in hot air so its pointless running 15psi. as you will dial in more heat, more detonation and probably make less power

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
