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.

seems to have fixed itself...i gave it plenty of time to warm up today and then gave it some and it loved it...seemed to be running fine.

thanks for the replys though...mite jsut get it checked over anyway.

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 ??

    • Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!
    • Welcome Alice......hope you have a bit more luck from here on! What was done in the build?  
    • Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!
    • Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!
    • I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.
