Umm, guys, just thought I'd say something, the original manifold keeps being referred to as "stock extractors". They aren't, the original one is just a cast iron exhaust manifold. Extractors are as the Coby ones- e.g tubular, better flow than stock. Actualy, "Tube Headers" is more accurate as a term, as extractors are really only a particular design of tubular headers which act to "extract" gas from the cylinder by clever use of cylinder pulses.

cheers,

hey guys, i've finally fitted the coby extractors on the car. cost $99. car is much more responsive from around 2500 rpm. i've ended up taking the pod filter off and putting the stock box on with trust panel filter, the sound is soo lound with the pod on!

only prob i have now is that for some reason it hangs low like dogs balls and scrapes on my driveway :P not sure which part exactly is scraping, i suspect its the part where it bends. gotta get outta the car and have a proper look.

hey denny,

its weird, my fuel economy slightly improved?! the extractors do hang quite low don't they, it makes me reluctant to lower my car.

i will organise that dyno day we spoke about as soon as i finish my exams (november 10) so a few of us n/a guys can compare numbers and not feel uncomfortable about the big numbers the turbos pull :( is there anything to 'tune' on a standard skyline? i was told u need at least SAFC or something before dyno tuning is worthwhile?

cheers

greg

hey greg, with a standard skyline i guess all they can do is advance the ignition timing. i've actually got the old school generation 1 safc, the one with the knobs on it lol. theres only like 5 tuning points though. i picked it up really cheap so thought might as well give it a try. anyone else got ? u can turn it up -30 or +30, i take it when u go towards minus thats leaning it out?

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
