hey guy, i just did a major service on my r33 and all was running just wonderful. i have had her tuned since putting on the new turbo (HKSgtrs). along with this i did the plugs to. i put in ngk BKR5ES-11. now i have been driving the car around for a week or so since being tuned and having the new plugs a nd turbo on and itr was tarting perfect, like almost immediatly...

but now i have to cranck her over for about 10-20 secs and put my foot down on the throttle. once she is strated she runs a little rough and then once it warms a little then it all calms down.

any ideas why this may have happened....???

this happned before when i first had my powerfc tuned and the tuner put new plugs in....

im thinking this may be plug related...???

i use bkr7e

never ever heard of them spark plugs...

if u have a turbo timer and u let it idle for 5 mins or so with the combination of wrong spark plug, could be fouling your plugs thus creating all them symptoms...

Next time ur at home and u try start the car n its doing that whole 10-20 sec thing, take one spark plug out and see if its fouled (covered in black dust looking stuff)

    • Like I said, "black magic" LOL In the end,  it is what it is, and hopefully, what this here knuckle head has done is an improvement and not a hindrance Not that I actually notice any negatives now, or that I will get any seat of the pants benefits when all is said and done, but best practice says I shouldn't be pulling intake air from the hot engine bay  Famous last words: I cannot see it being any worse than what it is at the moment 馃
    • If the gases flowing in those two tracts had the same properties, you could maybe use such broscience. But the exhaust has a different composition, different normal density, different actual density (because of different normal density, and mostly because of the massively higher temperature), and different viscosity (again because of much higher temperature). Consequently, all of the fluid dynamics parameters that matter, that you calculate from these inputs, such as the Reynolds number, friction factors (for wall friction) and so on, are all incomparable.
    • And we shall have to presume that Canada is the same?
    • In the US almost everything is E10. It can't exceed 10% by much or fuel systems have trouble adapting. At the same time because MTBE, MMT, and TEL are all banned they need as much ethanol in it as possible to boost octane.
    • I was mostly jesting. In my experience (and probably only my experience) the R34 GTT physical airbox space is actually too small to flow the amount of power it wanted. By sealing the box, I made it so it could only be fed by the ducts themselves. So you can seal it up and get nice cold air which IS good, but at a certain crossover point: More Hot Air > Less Cold Air I don't think you're at this point. In my case merely ducting the hot air intake with a very focused set of ducts counteracts the fact it's in a V8 engine bay. More cold air obviously best. The solution looks great.
