Hi, i just received my new power fc in the mail from Nengun.com $1003.18 delivered.

I already have profec boost control tho not hooked up yet, was waitin 4 power fc to tune them together.

i cant afford to replace the turbos at the mo and need them to last for awhile. So how much boost should i be running.

the car will be jumping on the dyno in the next couple of weeks and wanted to know whether it would be safe to run a bar.

i did a search looking for how much boost is safe to run on Standard 33GTR turbos. (i have 32gtr with 33gtr engine/turbos).

found beerbarons stats, running a bar. Is that safe????

i need them to last but want the most power i can get safely...

yeah, 1 bar is certainly as high as i would go on stock turbos, but that's not to say they will be bullet proof at 1 bar. 1 bar is generally just the accepted compromise between turbo longevity and increased performance. This is the mark for a couple of reasons. for starters the power gains start to taper off once increasing boost (on stock turbos) past 1.2 bar, so you are effectively then sacrificing reliability for not much more power. at 1 bar though you will have a nice power increse over stock, inlet temps will still be reasonable, shaft speed is still at the upper end of being reasonable and reliability should be fairly good. having said that, if your turbos have been pushed hard before, or had extreme heat cycled through them they may fail at any time regardless of boost, 1 bar, .8 bar whatever. But for good condition turbos 1 bar should be fine for quite some time.

a bit off topic here but oh well, i read in the pfc manual on this site in diy, that it comes with a boost controller.

im planning on getting a pfc soon and if i can do everything with the hand controller, without a boost controller then that would be good.

anyone know?

i dont really understand your question? the powerfc does not come with the boost contorl kit its a seperate option for an extra $300 ish. but it does plug into the powerfc and factory harness.

    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
    • @GTSBoy yeah sorry i know thery are known for colors bud those DBA are too in colors 🙂 Green will be good enough for me  
    • That's my life. Past-Duncan has a lot to answer for
    • Yep four point harness. Mounted to a bolted in brace running behind the seats. Dont use it for daily driving tbh but good to have for when its needed plus it looks cool.
    • I had to double check the thread title r34 gtt offset advice lol. Thought maybe i posted on the wrong thread. 😂
