been looking at the Greddy copy plenums.. iv had a read of a few topics and no one seems to say much bad about them?

question is anyone got one? did you notice any difference?

and duz anyone sell them on these forums?

cheers

I got one on my stagea recently (lots of other stuff at the same time). It is pretty good for the price but there are some things to watch out for like making sure the manifold surface is dead flat before you put it on. and some custom stuff needed like throttle body mounting and cable, aac mounting etc etc

pretty sure just jap sell them

I had an ebay one on for 1.5years.

Never saw a problem. Weren't any defects in the plenum. Didnt have any cyl 6 problems.

But I wouldn't recommend one for a more extensive build.

i was assuming all of the chinese copy manifold were coming from the same factory? as none of them are stamped or anthing? some just polish them up or powder coat them.. are the ebay one just the same?

Unknown quality of the metals used means porosity is a real issue to be aware of.

Mine was stripped back for some extensive finishing work, but got a heavy coat of epoxy enamel before installation.

The Chinese supplied it with a heavy coat of paint probably for the same reason.

myself and 2 others i know are using them, the chinese greddy ones, and they all had water leaks. my one leaked from the water gallery out of the manifold, the other 2 leaked into a port. both No2 runner i think. We all used some of that devcon stuff that my mate aquired from work and gave the water port between No1 and 2 a thin coating.

well, a guy who used to be mates with mafia from here had one on his rb25 and it had the same shit water jackets and leaking issues.

i have personally sold over 8 of them in the last 12 months and had no problems or comebacks. only issue i had was that they dont come with new rubbers for the injectors, but that was a quick trip down to the local nissan dealership.

honestly, they come up really good, and come polished on most surfaces.

only thing that is worth doing is maybe port matching and cleaning up some of the cast markings, as it is only a china one...

www.autotecnica.com have a geezer anyway.

i'm not going to plug the store i work for, as they dont pay advertising, but its pretty easy to work out who sells autotecnica anyway.

    • 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)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
