  1. not a picture of my car, but i have this part behind the ABS module
  2. Interesting. I never made the connection on the Group N. Always read it like "gruppin". What's the difference between -5 and -7?
  3. I did more research. They are -5. Are they any good?
  4. The previous owner told me that he had a shop replace the old turbos with these. https://www.enjukuracing.com/products/garrett-rb26dett-gruppe-n-turbo-upgrade.html Anyone know anything about them? Looks like they are just GT2860R's? Not sure why they are renamed Grup-N... Does the compressor wheel look like they are in okay condition?
  5. Just wanted to update everyone. I finally got around to working on the car this year and I did a boost leak test. It seems like i was hooking up the 3 port mac-valve correctly, but there is a massive leak on the rear turbo's wastegate actuator. Where the seam comes together.
  6. Doing it this weekend. For sure this time. Thank you forum gods. And im running map sensor now with the haltech. Still have the AFMs attached to the mushroom dome shaped air filter things
  7. Revisiting this thread again x2... 1 year later. This car has been an ongoing project between life. But, I never removed the re-circ pipe. I know, shame on me. But since then, i took it to get tuned and only making about 280hp (lame) and i'm chasing a boost issue where the car wont boost past 7-8psi. Mac valve installed. Haltech Platinum pro with the map sensor. This is the first time i've tackled the turbo side of things, but i have that side somewhat taken apart to chase the waste gate vacuum lines. And noticed this stupid pipe again. I'm peicing together the puzzle and @GTSBoy mentioned that it was a big vaccuum chamber and said a bunch of car math stuff that I couldn't quite follow the car math (im trying). You guys think this would be the culprit? between rotting vacuum hoses? i'm making a DIY boost leak tester this weekend.
  8. Did you run the power cables for the mac valve to the other side of the car near the fusebox? Utilizing the stock boost controller cables? or did you run new ones?
  9. @Milhouse Sorry to hear that brother. I never got to the bottom of mine, although i didn't have a large amount of oil like you described. I just wipe it up as best as i can everytime i'm under the car and if i ever have to remove the engine, then i'd find the root cause of this leak. It sucks that you just had your engine out though.
  10. If i did that, how would i run the 2 electrical wires across the other side cleanly? Is that what you guys did?
  11. Some advice, i realized that the cable broke, because there is a big ass washer on the seatbelt thing and it was squeezing the cable causing it to have extra tension. Make sure that big washer isn't sandwiching the cable.
  12. I replaced this cable recently. I purchased it from concept Z performance. And it was a R34 one. Can confirm it works. https://conceptzperformance.com/nissan-infiniti-nissan-oem-trunk-lid-gas-filler-opener-cable-nissan-skyline-r34-gt-r-gtt-84650-aa100_p_56279.php
  13. Is it possible that there is a leak somewhere? or if my turbos are gone? or if my wastegates are stuck?
  14. Not sure why everyone thinks i hooked it up wrong, but Josh is spot on with my vacuum line set-up. The picture of my MAC valve shows the 2 red vacuum lines going to the water/coolant combo pipe and the black vacuum line is going to the last nipple under the plenum. (See below) Josh i have a few questions: 1. You might need to use an air compressor or just blow through the hoses. When it's off it should connect port 3 to port - Can i blow air with my mouth? 2. Put 14 psi into port 1 vacuum line and verify you can hear it venting into the intake piping before the turbos. It shouldn't hold pressure substantially. - Why 14 PSI? I have a compressor, but im not sure if i can get it to those tolerances.
  15. Hey guys, sorry i just got back from my trip to greece. I was able to take a video of everything. See the link. Dont judge me for the spaghetti wiring/hose mess right now lol
  16. 1. I thought this turbo pressure line comes from the plenum? Is there a way to get the turbo pressure line near the turbos? 2. How do i plumb in the selonoid in its internal gate so it goes only 1 way?
  17. im about to just drive this car off a cliff I swear i hooked up everything exactly like the diagram. could it be a boost leak?
  18. yessir, haltech platinum is in. I did multiple runs and my manifold pressure (boost pressure) never exceeds 8psi. All the settings are correct. Open boost with 33 hz. No matter what duty cycle % i put, it dosent change boost pressure.
  19. I found it in my glovebox. Looks like whoever owned it before had did some snipping. No clue what it is for. Any ideas?
  20. Alright, i connected everything properly, but my car isn't boosting past 7-8psi. Any ideas? 3 Port Solenoid is working, i hear it clicking.
  21. im talking about a generic diagram. Like this one:
  22. Interesting. Those turbocharged engine diagrams usually has all the boost go straight into the intake valve lol. So i thought they were the same thing.
  23. Does the factory boost gauge pressure = turbo pressure? Couldn't i just T into that line by the firewall? I mean its too late, i already shredded all the skin on my hands, but man.. https://www.gtrusablog.com/2019/06/where-do-i-tap-my-rb26-for-boost-sensor.html
  24. Thanks man. Im in the garage now. Dear god, that last hose is so far back. I forgot how much of a pain in the ass it was to work under the plenum.
