Hi there,

I have a '96 R33 GTS-t and found that when under load and boost it pings in any gear. The car is standard except for a cat back. I changed plugs and at same time air and fuel filters. I noticed that the fuel coming out of old filter was bloody dirty. I know fuel quality and dodgy fuel pump can be a cause of pinging as is timing etc. Do you think that dirty injectors would be the probable cause? The car runs very well otherwise with great fuel consumption.

Thanks, Pete.

Happened to a R32 I imported years back. Its mainly due to your fuel pump filter blocked. You probably also heard a loud buzzing noise from the pump too. Had to professionally clean the whole fuel system and the problem went away.

Or unless you are running too much boost.

      R34 GT-R Positive Battery Cable Routing

      By Beanie · Posted

      Hi there, after a quick google search I found this topic as I am also relocating the battery to the boot of my 1998 GTT. I was just wondering how you got on with installing the re-routing and specifically the installing of the harness protectors? How do they attach? Are they just a simple "click-in" affair, or do they attach with bolts? Does the GTT have all the necessary fixing holes for them, for example, where they locate on the chassis? Any help you can provide would greatly appreciated.

      R34 squeaking sound from passenger front area

      Stock less likely to carry one like that than urethane, but still can, especially if the bolts are not as tight as they should be. If it's making that much noise you should be able to use a hose as a stethoscope> stick one end in your ear, crouch down and wave it around the various possible noise makers and get someone to lift the front end at the guard lip.

      Broken actuator rod. Could be one of a couple of them broken. Or, it's locked and the central locking actuator is broken/stuck or the actuator rods between it, the lock and the key barrel are jammed or broken similarly. You'll probably need a locksmith/mechanic who is experienced with using slim tools to reach down next to the window glass to manipulate the mechanism. That's assuming that it is not so severely jammed/broken that nothing useful will move.
