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

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?

      boost source Size Garrett gt28 gen2

      Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.

      I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things

      I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt

      So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm.

      Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
