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.

      Got the passenger door on plus the master cylinder and booster. Loaded up to take it home. At home, the colour changes a lot in the light.

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      Nothing cheap, but I have seen the AC Hydraulic DK13HLQ which is pretty close to what you're asking for. The problem is the hydraulic cylinder mandates that the back of the jack be a certain height and Skylines have fairly deep inset floor jack points. A more certain and cheap option is to get some nominal 2x10 inch lumber boards and have one board be 1.5 feet, the other board 3 feet. Glue it all together with lots of clamps to maintain pressure. Make two of these. The ramp suggested above is a good idea, it takes quite a bit of clutch slip to get over each of the boards. I only need the first ~1.5 inches for my low profile jack on a standard ride height car but a lowered car you want to go up to the full ~3-3.5 inches. Paint it or store indoors if you want it to last.

      Boost cut after swap(RB25DET NEO) R34

      Ok. And Nistune? I read (here too) mainly on Stagea threads that it can by "turn off" with Nistune. But they say they still had the sensor plug in. Next week iam going to the Nistune(and other ECUs) tuner so i can finally make it work. I drove the car home and apart from the cut it drove great. No misfire no smoke no hesitation or rough start...so hoping it is this sensor that is missing

      I just stack 2 pieces of 200x50 timber on top of each other. Total length about 900mm, with the top one being a little shorter and both having a 45° angle cut on them to make the front edge a bit of a ramp. Put these in front of each front wheel, drive up on them, throw the trolley jack under. Takes 1 minute. Scissor jacks can eat a bowl of dicks. I never use on under my car unless desperate.
