hey just a quick question.. i've got a r33 GtsT.. when i'm driving it pulls boost it won't go, it feels like it's holding back... on the boost guage it saying i'm on boost.. but yeah it doesn't go it's like it's lagging.. BUT when i turn my car off then on again, it work's normal it pulls boost then goes good... it only happens sometimes though.. any ideas??? i've checked all hte piping and vaccum it's all good... but yeah does anyone have this sort of problems??

i've got a blitz computer.... yeah it's weird when it happens, at the lights i turn the car off hten turn it back on then it drives normally

i pulled all the plugs in the engine and cleaned it.. even took out the coil packs and cleaned them too...

update.. theres' oil in the last cylinder... and spark plug was BLACK AS!! got new ones and cleaned the oil away... works BEAUTIFUL!!

5 days later... it happened again.. so i checked if there was oil in the cylinder again.. there's none so i cleaned the ends of the spark plugs. now it works good again..!! what the!! again when it did happen, i turn my car off then on again.. it worked normal again..

can't figure it out

oil in the last cylinder?

Its got bad blow by. If I were you, get it compression tested, and stop boosting in the mean time before you really wreck it.

Sounds like you are going to need a rebuild....

I have the same problem. I have a R32 GTS-t and just put a new air intake and boost controller to put it to 12 pund but still feels when it boosts not much quicker and it has alot more potential. Any idea's from anyone what this could be. The car is completely stock other than this.

why am i going through oil so quickly.. there's no leak that i can see

Oil isn't going to magically disappear. It can only be leaked out or lost in the cylinder.

Get a compression and leakdown test done, as others have said. But it looks like rebuild time.

rory_kiernan : stock r32 is 10psi? and you've gone to 12psi with not much else done... :blink:

i've got forged piston and bigger turbo...

it's running good now.. but i happens probably 2/3 times a week.. not all the time when i driving... but it's annoying when it kicks in.. cos it feels like i've lost alot of power, but the boost is there... it's set on 15psi. but when the problems kicks in it only goes to 7psi

Hey Mr Sly, i have the same problem as you at the moment, by boost laggs, but only every now and then, and im only running stock 7psi as well, with a stock ecu at the moment, any one have any idea on this one? r33 series 2 1996, it lags some times on winding up and other times around 5psi, and you can feel the pull then it kicks in, then it pulls then kicks in, its annoying the hell outa me as well, anyone think this a spark plug issue? (i havent checked them yet as been busy, but its the first thing im going to check tomorrow) just got the car back and this happened

      Yes, but 2 things of the top of my head, 1. Legalities of nitrous on a street car. 2. No chop chop. I fully understand that there's much cheaper ways to make power, and whilst a wet 50 shot is fairly cheap to install, bottle fills are expensive, and bottles always need to be refilled, and nitrous also has its own inherent issues with reliability, and tuning, from my experience of others using nitrous, it doesn't take alot to lunch a engine real quick if something goes slightly wrong when spraying, if I wanted a big chunk of additional powers, a spooly boy would make alot more sense, disregarding the additional engineering, supporting mods and other logistical issues of sticking a spooly boy on a car that came naturally aspirated from factory  In the end I'm not racing for sheep stations, and I don't really care if people make more power, or are faster than me, or spend less, or more than me, the only thing the car needs to do is drive around and make me smile, which it is doing now Really, I just want a shiny new intake to look at when I'm cleaning the engine bay, and of course, some more induction doorts, and maybe even that 5kw for that elusive 200hp cherry on top that I might get If the FAB9 intake plenum, TB and air filter box thing doesn't eventuate for whatever reason, Plasmaman do one, not as fancy looking, and a fair chunk of more cash is required when including the TB and other bits and pieces that are required to install it, but, it is another option that is available to me if FAB9 one does fall down (but I really, really.....really, want the FAB9 one though) TL;DR. You want what you want
