Hey guys,

Sorry if this has been posted before.. i've tried multiple searches but cant find anything..

Just wanted to know whats stock boost for an r32 gtst?

I currently have a slightly modded r32 gtst and would like to know what stock boost is, and also how much the turbo could handle, on a cold night, without turbine failure.. i.e. safely.

Mods include - 3" exhaust (need to check up whether its a turbo back or cat back), pod filter and EBC.

Its currently running .8 bar boost which is about.. 11 - 12 PSI..

Dont run anymore boost unless your going to fit a frount mount. The standard side mount cooler suffers from heat soak and also 11 - 12 PSI is pretty much the limit for a stock turbo i would say say 13 - 14PSI max using the stock turbo and a front mount. Im sure some of the lads here can offer a more detailed answer and more advice.

stock boost for r32 gtsts is 10psi, like everyone above said you should see it spike abit more with aftermarket parts eg, exhaust, airfilter etc etc

mines currently running 13~14 with stock cooler, looking to upgrade to bigger one soon.

I see this topic and its funny to read everyone's posts about stock boost. My stock boost gauge reads about 6 psi and my after market reads around 8psi, yet when i boot it on the guage at the mechanics it shows around 10psi. Most people will say its 10psi although as stated its not good to run it too high for long periods of time with the stock cooler and turbo but then again there are guys out there running in excess of 12-14psi with stock turbo. Just my 2cents

Uhh.. i actually did.. but didnt find anything that applied to me directly.. other people had front mounts etc..

So what about on a cold night? Wouldnt that be like having a front mount already since the air surrounding me is already cold?

To a degree yes but then the biggest problem you have with the difference in ambient temp is the way that you have your car tuned for normal day to day driving. One of my mates has a stock R32 that runs like a dream on a colder night and his older brother who's car is slightly moded runs worst on a cold night. When it comes to stock boost and stock turbo i would stay at 10 mayb 12 psi but not for long periods of time and not for daily driving.

      Question about BoV on RB25DET NEO

      By joshuaho96 · Posted

      Atmospheric vent requires something that doesn't use a MAF for load. You would need a standalone ECU for that.

      Rb25 trigger kit and timing misalignment

      By drifter17a · Posted

      Hey all,   I’ve got an RB25 with a trigger kit that includes a crank wheel, and I’ve hit a wall trying to sort a timing belt tracking issue. The belt either rides right on the edge of the cam/crank pulleys or walks slightly forward once the engine starts. It tracks okay-ish for a moment, then creeps right to the edge—and honestly, it’s stressing me out.   I’ve spent hours removing and reinstalling the belt, double-checking everything:   Tensioner setup is good, checked multiple times Idler pulley and washers are all in the correct places Followed the RB25 timing procedure step-by-step     The only thing I changed was the rear crank washer—I swapped the OEM one for a Neato version, and it made things worse. The belt now sits even more forward than before. I’m beginning to think the crank trigger wheel itself (from the trigger kit) is the issue—poor design or slightly off dimensions.   What’s strange is that with the previous belt setup, it actually ran fine for a couple of years—around 4,000 to 5,000 miles, even with hard driving and high RPMs. But even then, the belt was always riding right on the edge, and I know that’s not ideal or safe long term.   At this point, I’m debating whether to:   Machine a few mm off the crank trigger wheel to bring it back in line, or Replace it entirely with a better-designed unit     Only thing is, I already have the Cherry Hall sensors, bracket, etc.—I just want to replace the wheel only, not the entire kit. Anyone know a brand or supplier that sells just the crank trigger wheel on its own?   Would really appreciate any feedback—especially from anyone who’s run into this exact issue and found a reliable fix.   Thanks in advance.

      Hi...a little refresh. Is Nistune gonna be enough to run BoV? Or do i need some proper ECU?

      Yep that's pretty much what I want to see. Racecars that look and sound like the Group A but with newer tech underneath to make them faster and safer. I'm sure there's enough VK-to-VN commodore, E30 BMWs and Foxbody mustangs shells around to make up a decent number of cars with hopefully a couple of sierras, rx7 and R31s in there too.
