I found a table from a Japanese website that had Inconel listed.

R34 N1's? I woulds say they would yes.

It does look like you have steel wheels judging by the nut. However, you still have the 0.48 A/R exhaust housings so they aren't N1's.
The "steel wheel" material is "Inconel" which is a nickel alloy and is non magnetic.

So is it possable to make more power with the metal turbine wheel? Or is 15 psi maxing out the compressor side?

  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.

  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.
