hey guys

got an r32 gtst with a r34 turbo with r32 actuator got it running 14psi nistuned so everything should be sweet

getting surging around 2-3000rpm more on cold but happens when warm to.. im thinking it could be the actuator buggering up sometimes it boost's Fkn hard sometimes it doesnt but still hits 14psi

im running new splitfire coils on .8 gapped coppers

when i baught the car it had a catch can but i had to get rid of it to get over the pits so its plummed back into the stock intake

when im boosting it blows black as usual but a little bit of white aswell.. could the white smoke be blow back from the turbo? meaning do i need to put another catch can on it? ive also noticed with the stock boost gauge in the car it moves ferom 0 to -7 as it chooses could the gauge moving b sending mixxed signals to the ecu?

also a mechanic mate of mine told me it could be something to do with the brake cylinder??

any opinions would be wikid!

Think you need to probably explain the situation a bit better

Are you mainly worried about the white smoke?

Could just be moisture in the exhaust when cold from sitting over night and then as the exhaust heats up it just evaporates into white smoke...

White smoke is usually an indicator of water/coolant

if its a bluey smoke then it could be burning oil.

But more info will probably help

now thinking about it my water pump went a little while ago so i got all my belts pump and radiator redone so yer main concern is the smoke drawing unwanted attention and i dont want to do any engine damage.

iwhen i baught the car it was a stock rb20 turbo running a stupid amount of boost so got rid of that and put the r34 turbo on.. ive really only noticed the smoke since getting a nistune done... could they have buggerd the tune up? and apparently u can smell fuel from my car driving about 20mtrs behind it..

does that help anymore?

      R32 Gtst - Track Car

      By bcozican · Posted

      it takes so long to get things done but ... they are nearly there and we hitting the track soon again  So - at Perth Festival of Speed the car unfortunately had a decent off, wasnt me driving, wasnt the person drivings fault. Long story short car got sent very fast towards the wall without the control on throttle from the driver input and a disaster was averted but there was damage that needed to be fixed - carbon busted and alot of bent bits The splitter got munched and had to go back to get fixed - took a bit to get it there, fixed and back but got a surprise package when a new double element higher DF splitter came back - nice surprise !  and first person to have one     At a car show I took the car too some punks stole one of my carbon indicator blanks and stomped on the other so had to get a new set of headlight / indicator combo from tops stage so got front fender vents as well to put in the order     While all this was happening the new MCA golds turned up and did some fiddling around with those   Put in the flappy paddle system and clutch lockout wiring/ system   We have also put shorter gearing in top top it out at 300 kmph in 6th gear  where previously I held 5th to 282 at SMP and 277 in Perth   Looking for better control and faster acceleration     I wasnt intending on doing pedal box I was managing with the brake master replacement system I had going on and adjusted std pedals but on applying the clutch switch to the old system we found the *insert technical word here * bar that goes from the pedal to the master was bent about 40 deg and about to snap = lucky find otherwise be a bad bad time - discussion was had about getting a custom bar built to withstand the load but in reality it was time      making any suspension, wheel or anything adjustments to date has been a nightmare - aero off, adjust, check and repeat - time consuming and hard - short of going full airjack system we fashioned some external manual car lifts this will make life a million times easier     All the bent framing, some intercooler pipes and other has been fixed and replaced and after 6 months I finally have the car back at home in my control so its get to work on it, set ride heights, wheel align and will start track testing again soon   So ultimately other than a few flashy bits nothing actually looks likes its been done but in reality alot has. Typical   We'll see how all this goes

      I'm far from an expert, but for sticking bits of metal together occasionally I got a MIG, the biggest one I could get with a 10a plug (because while I have some 15a GPOs around, they are not everywhere).  Also, because I get through SFA, I just buy the small disposable gas bottles at Bunnings, I'm not opening a BOC account to get through 1/10th of a full size bottle each year

      Ignore the BOV / recirc valve question. You have an NA and shouldn't have one. If there magically is one though... It should be removed, though it shouldn't really effect it in the way one will for a turbo motor with it venting to atmosphere while running an afm.
