sorry forgot...ok well the boost guage says it's boosting ...but it doesn't feel like it. normally i'd feel dumped in the seat a little more...basically it feels like theres less power. the boost guage also seemed to be showing it boosting higher sooner. i have only just started (last few days) revving it higher like to redline. lower RPM doesn't feel like theres much boost where as you used to be able to feel it more. does any of that make sence

Maybe your loosing boost(-ed air) from somewhere. Get someone to drive behind and look for black smoke coming out the exhaust when you floor it. Get your pipes and rubber intake hoses checked for leaks.

the 02 wont affect how the car runs, it will simply affect how much fuel you burn up. you can simply unplug the 02 sensor and your car will just run mega rich. its on the dump pipe just after the heat shield. youll see a plug thingy tapped in the exhaust pipe with 3 wires, thats the 02 sensor. you can unplug and the ecu will just run rich and waste fuel. i cant tell what the problem is but it wont be the 02 sensor. what mods do you have to the car? without knowing anthing it sounds like boost / fuel cut from too much boost or some sort of retard with the stock ecu

yeah i know bout the o2 sensor not changing performance...jsut thought coz i'm sending it in to do that mite as well get boost chekced aswell. when it does boost it seems to go past the marker on the stock boost guage (the one without a number) seems to go clsoer to 7+

i've got 3' exhaust

pod filter

ok the flat feeling is the ecu retarding timing and doing boost / fuel cuts

why your hitting or going near +7 i dont know but this will be the cause.

+7 on the guage is +700mmhg which is 14psi. about 11psi-12psi is the limit before the stocker ecu will cut in and do boost / fuel cut. when this happens you floor it, the car makes boost, normal noises but it feels flat and doesnt accel very hard. have you done any bleed valve changes, removed the stock solenoid or changed the tubing etc?

i've only had the car for about a month and havent changed anything myself...or had anything done to it. i'm new to modifying and jsut elarning so... it's come from japan the way it is (i'm first owner is ausrtalia) so i'm not sure wat it's got. any ideas or should i jsut get a general check when i get the o2 changed. could any of this other stuff be contributing to my bad economy aswell 250 per tank

Hey mate i had the same problem, basically its wat had been just before by Paulr33. Your car is retarding the timing and therefore you feel that flat power band during the rev range at around about 4,500 to about 5,800 than it pulls like a rocket again. Well Basically its your shitty bleed valve this was the problem for me i had a turbo smart bleed valve and it would spike to 15psi no matter what the setting. My car was making 217.5 rwkws at 11 psi but the power curve was to the shit house, and basically a r33 with say 170rwkws would have eatten me for breakkie. I had the GCG hi flow but all the same the problem your having is to do with the boost spiking. And in my opinion get an electronic boost controller if you can afford it and maybe a dyno run just to make sure thats the problem. Does you car pull really hard from like 6,000 to redline?

have a look on the LHS strut tower.. you should see a little cylinder bolted there with two small tubes going to it, and an electronic plug.. that is your boost solenoid. Just see whether that is hooked up.. and whether the hoses are actually going anywhere.

I assume you are talking R33 ??

    • I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k . 
    • Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?   
    • Yeah I've spotted this one too, whenever it's lotto superdraw week and I'm browsing car sales dot com for my new ride They must be dreaming, maybe it's worth 150k for the link to Brock?
    • 100% accurate!  We are a pack of know it alls....  But, I bet people go to you when they have a problem! I've been on a bit of a clean up rampage too over the past month!  I've thrown more shit in the bin over the past 2 weeks than I have in the past 3 years combined! Anyway, it's all good fun being different! My wife sometimes does not agree!  
    • ADHD in all form isn't about "can focus, or can't focus" or is hyper active or isn't etc.   It's all a dysregulation. Either time feels to be stationary, or time just vanishes in a split second. We are either under focussed on the task at hand (as we're over focussed on our surroundings) or we have no idea an atomic bomb went off beside us as we're so hyper focussed and locked in on things.   Not to mention the rapid fire thought process. What it takes a "normal" process to think up a solution to a problem, ADHD will be able to give you 5 different ways to solve the problem, and the pros and cons of each. While we can be highly impulsive and lack the ability to "control ourselves" we can also become paralysed with the inability to make a decision for ourselves. While most of us have an OCD like requirement for perfection, we lack the ability often to remain focussed to get things to a perfect state. Those with undiagnosed ADHD as adults, can often find the last part actually stops them ever attempting to do things that they have the ability to do, as the reasoning is often "if I can't do it perfectly, it's not worth doing"   As for projects... Ha ha ha, I still need to take the other half of my wall trim down in the Fiance's office so I can paint it. Need to finish digging and running the back yard drains, my R33, getting the Ninja bike registered (now being sold), the moped project, fixing either of the lawn mowers so they're reliable, along with a myriad of other things.   It's why I've been going through lately and just being brutal and clearing projects off that I won't actually ever complete. IE, moped will go to the tip, or be given away, bike is being sold, Subaru project being sold, some parts for other projects given away. Or I've been making myself focus on one thing at a time, by ticking off the smallest quickest ones first.   There's also a reason by our mid twenties we seem to be "know it alls", as we've all been down some of the weirdest and oddest rabbit holes when you follow the dopamine trail. It's often also why we're more a jack of all trades, but not a master of one.   However, pretty much all of my hobby projects, in one way or another, all come back around to automotive. That's my zen area.
