    Take a photo and post it.

    The Nissan pipe will have a small orifice (Restrictor) in is.  Does your new piping?

    PCV = Positive Crank ventilation.  When you have manifold vacuum it will suck the blowby out of the sump.  It is usually on the exhaust cam side of the engine half way along.  What did you do to the piping on this side?

    Tbh this is my first import and im quite new to dealing with them. The engine is NEO not sure if that matters. It seems to run perfectly well.. actually better... boost is more obvious and same with power. But with the check engine light on im worried if i continue driving it as my daily I'll damage something expensive :'( As you can see in the picture its just a basic setup to be considered legal so if this is wrong please let me know of a better way? 

    Cheers!

    Did a search and couldn't find a topic like this.

     

    Any way, did a catch can install on my GT-T yesterday and nI now have a check engine light on... and dont know what the problem is. Its plumbed from the cam breathers to a tee piece to join them together, going into the 'in' on the can, then the 'out' going back to the intake before the turbo. Have I dont it wrong? Id check for a pcv but tbh I have no clue where or what it is. Any better suggestions for a closed loop system or and help would be great! 

    Thanks in advance guys!

    R34 gtt idle problems and bad running

    Forgot to add a detail about upgrades to car

    R34 gtt idle problems and bad running

    So basically as title suggests i have an r34 gtt. Basically stock except using power fc with rb25neo, steel bearing turbo tuned to 13psi, and walbro fuel pump (255 i think? Cant remember exactly)

    Her idle is running terrible. Constantly hunting idle making it sound like its got fat cams lol, and even worse when cold and cold nights. Tends to surge on cruise speeds (60, 80, 100) as well and a light throttle tap temporarily stops it. Under boost she pops alot on revs over 4k and just found that shes making sucking noises under the hood somewhere, IAC have been removed and no gunk is inside but cleaned and replaced anyway. 

    Just today she started getting worse, started making a weird  (soory for the silly description but its all i can associate it to) robotic kinda wirring noise everytime it tried to raise the idle rev during hunting and then stalling not long after. Will attach video link.

    Ive taken it to multiple mechanics and all just seem to be trying to drain my money coz ill get the car back "fixed" but its not and all they say when i bring it back is "no idea why its doing that". Its driving me absolutely insane... just want her to run right as shes currently my daily 

     

    Any help will be amazingly appreciated, shes due to go into a new mechanic that specializes in rebuilds but even they say they may not find the problem.

    Awesome cheers for that. I did have a look aeound but being new to imports im not too bright on where to look haha. I could get it locally but they are charging at least 200-300 more to be built. Will definitely check this site out.. thanks heaps!

    34gtr radiators fit 34gtt?

    Anyone know if an aftermarket 34GTR radiator with fit into a r34 GTT? My local dealer only has GTR radiators and not really wamting to wait 8 weeks for one from japan if i can get one in a week.

     

    My radiator had a huge blow out, ceacked between the fins on top and bottom driver side. Apparently too much pressure. Anyone know what could cause this as well?

    Thanks folks!

    Hey mate, welcome.

    If you've got a GTT you have an RB25, not RB26. Just fyi. (probably just a typo :P )

    Also, you say it's stock but it's running 15psi? That's too high buddy and is also likely a cause of some problems pending the tune. Turn it down to 10-12psi before you pop your snail!

    It's also very strange that disconnecting your catch can would help with the issue you described. You've gotta be careful with your plumbing with stuff like that too, but you say it's running right now so I'll take your word for it.

    Throw up some pictures so we can see what you're working with. :) 

    Yea my bad rb25 neo (typo) but 15 is ok. Mechanic had a look and said its highflowed... my mistake i shouldve mentioned that. 

     

    But as for the catch can.. the problem was it was shooting black smoke and sometimes white (both on boost and idol) was repaired by the mech but kept happening.. he checked everything. All seal.. patched up 7 vac/boost leaks and reset to factory the power fc and completely new tune. Had a hunting issue before but its not soo bad now on idol. I find it weird to be running without the catch hoses connected but it seems to like it :/ if i connect it up it feels like its not getting enough breathing room. Will grab a pic up tomorrow, if there was a way for vids id do that

    New r34 gtt NEO owner

    Hey people, new 34 gtt neo owner here, been on the site here for a while finding tips for my car and finally decided to join up. My car is a stock R34Gt-t RB26 NEO and she hates me haha. Had alot of problems since I bought her unfortunately and all i want is for her to run smooth. Shes gota power fc with the steel bearing turbo, tuned at 15psi but has probs with a power cut (i think) on WOT boost. Felt like she wasnt breathing right so disconnected catch can and she was great.. albeit illegal... so thats just the tip of the iceberg lol. See you in the forums!!!
