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

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 used the radium thing, makes the whole parallel assembly a lot more compact compared to any other way of doing it 
    • Racetronix also sells those ethanol content sensor bypass blocks. Adapter, Flex-Fuel E85 Sensor High-Flow Bypass, In-line No Sensor (ADF-FLEX-NS): Adapters - Flex Fuel | Racetronix Ethanol content sensor are originally designed to be on the feed line. These bypass blocks are meant to be ran in the feed line and not return. The continental ethanol content sensors have a 3/8" ID and not 5/16". This is why they are ran on the return line directly in conjunction with a low threshold sampling value VS in the feed with one of these blocks.    Haha we think alike, I used both original feed/return for 8AN feed, and one of the Hicas lines as a 6AN return. I also capped off and left the other Hicas line as a spare. 
    • Interesting, I haven't read about the issue with oil getting into the speedo in the cluster before. I'll have to take more notice with mine. The speedo on my R32's when I've run factory diff and tyre size have never been accurate as far as I can remember. The non Type-M GTS-t did come with 15" 5 stud wheels and smaller brakes, but that's less than 5% of them.
    • Good to hear the condenser you picked up off my brother worked all good. Do you think there could be an issue with your AC compressor itself or the clutch on it then? I don't know a lot about them so I can't really help but keen to hear what it ends up being. Keep the build thread going man, it's nice to look back on over time.
    • This is a story of my life things, I learned eventually (thanks to someone calling me out) that my enthusiasm for discussing and sharing ideas that it came across as arrogance and I'm like... WTF?!    One thing I'm pretty sure I justifiably pride myself on is knowing that everyone will have things they can teach you, and you're always going to find out that something you think you know turns out wrong - you just don't know what it is until you get there.   Just the bursting enthusiasm that comes with ADHD when you hit something that gives you dopamine dumps can come across like you think everyone else is wrong or don't matter. But yeah, I'm a software engineer by trade and also do tuning in weekends and 100% have long had a reputation for  quickly making connections when resolving problems or forming solutions that I've sometimes had to take people form a long walk from start to end to explain how I ended up where I did when it's seemed "too simple" when I've stated my initial case, and had the "WTF" type reaction when they've realised how much was actually considered haha.   My reward is that I get all the curly problems thrown at me.
