hey guys the popping on de acceleration has been getting worse for awhile and last night at the drags made it ten times worse. Orginally i thought the cat had shit itself but i had it on a hoist today and the exhuast is all good. And there appears to be no exhaust leaks and no intake leaks and it is holding boost what can course this poping. It appears to be down on power as well. I am hoping that a spike to 16 psi last night down the strip hasnt affected the stock turbo.

its normal to have abit of popping, my pops it ass off normally :)

If you think its excessive or getting worse i would check for intake leaks, just simple things like tight hose clamps and all vacuum hoses are on tight with cable ties. What bov are you running? Could that be leaking slightly?

Also what ecu are you running? stock or tuned?

if the turbo is still boosting fine without funny noises it should be ok, a quick 16psi spike wont hurt it, continous high boost will.

Also remember it is summer now, turbo cars hate the heat so its normal to have a significant drop in power during the day aswell.

lol yeah its good but mine sounds pritty bad more like a old shit box back firing but instead its poping lol i will check the cooler pipes and extra tomorrow. It has a stock ecu but its been retuned by toshi and i am running a stock bov

check your plugs for fouling,

my gtr runs pretty rich, and starts backfiring after about 2 months, especially in summer, the plugs will soot up, i just clean them and problem gone........

hope this works for ya

i will check the plugs there only alittle bit over a month old and the o2 sensor is good its not old at all and tested it a couple of weeks ago and i would mind the pop if it wasnt to excessive but it is quiet bad

I had a problem similar to this turned out to be a leaking o-ring in an injector.

however it can be a number of things a small vacume leak, plugs, afm, 02 sensor. since plugs and 02 sensor are newish i would look at clean afm, then change fuel filter (never know) then look for any fuel leaks

    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
    • I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option 
    • You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
    • I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.
    • Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
