skylineGT Posted January 9, 2010 Share Posted January 9, 2010 Have just purchased first skyline and i'm not sure if the boost gauge is reading right, it generally sits in the negative and only goes into positive boost when accelerating hard, is this normal?

30three Posted January 9, 2010 Share Posted January 9, 2010 Standard gauge isn't the best. Check the line for it hasn't cracked as they tend to do. It comes off the intanke manifold near the firewall, it's a 4mm black rubber hose Link to comment https://www.sau.com.au/forums/topic/303138-boost-gauge-on-skyline-r33/#findComment-5025101 Share on other sites More sharing options...

PM-R33 Posted January 9, 2010 Share Posted January 9, 2010 (edited) Have just purchased first skyline and i'm not sure if the boost gauge is reading right, it generally sits in the negative and only goes into positive boost when accelerating hard, is this normal? That is the corect operation of a boost gauge. Under no load the intake pressure sits in a vacuum, demonstrated on the gauge as a negative pressure. Once the engine is under sufficient load and the turbo is "spooling" the pressure will go into a positive "boost" it will continue to climb until the wastegate cracks open and the boost will stabilise at a single value controlled by the wastegate/boost controller. Have a read of this, good article to explain the basics. http://www.howstuffworks.com/turbo.htm Edited January 9, 2010 by PM-R33 Link to comment https://www.sau.com.au/forums/topic/303138-boost-gauge-on-skyline-r33/#findComment-5025107 Share on other sites More sharing options...

PM-R33 Posted January 9, 2010 Share Posted January 9, 2010 Hmmm that doesn't ring any bells. Could be something from the previous owner. Post up a pic if you want and it might help.

Grimnir Posted January 9, 2010 Share Posted January 9, 2010 that knob will be the dimmer control for the dash lights. Link to comment https://www.sau.com.au/forums/topic/303138-boost-gauge-on-skyline-r33/#findComment-5025491 Share on other sites More sharing options...
PM-R33 Posted January 10, 2010 Share Posted January 10, 2010 Ahh yep that's probably it. Sorry, mine doesn't have a dimmer for the lights so i forget some skylines have that.

skylineGT Posted January 11, 2010 Author Share Posted January 11, 2010 another question, is it common for the exhaust manifold nuts on cylinders 1 and 6 to come loose/ fall off, and is there a special nut/washer type to stop this?

gotRICE? Posted January 11, 2010 Share Posted January 11, 2010 another question, is it common for the exhaust manifold nuts on cylinders 1 and 6 to come loose/ fall off, and is there a special nut/washer type to stop this? Totally normal. Just kidding dude. Maybe the studs are broken so they arent staying tight? Best thing to do would be to find new ones and just put them on tight.... tight tight. Maybe even some threadlocker? Link to comment https://www.sau.com.au/forums/topic/303138-boost-gauge-on-skyline-r33/#findComment-5027743 Share on other sites More sharing options...
S1LV3RTRACKS Posted January 12, 2010 Share Posted January 12, 2010 Standard gauge isn't the best. Check the line for it hasn't cracked as they tend to do. It comes off the intanke manifold near the firewall, it's a 4mm black rubber hose I had this issue. The rubber hose becomes brittle and cracks appear which messes up the factory boost gauge. I had some 4mm rubber vacuum hose lying around which I installed and all is fixed with the gauge. Very easy to fix.

I had some 4mm rubber vacuum hose lying around which I installed and all is fixed with the gauge. Very easy to fix. Yep, I had the same trouble. That little hose just gets brittle with age. Also causes a vacuum leak, which harms the boost as well. A few bucks worth of hose from Autobarn should do it!
