Lousy news guy did you stil have a 32 crank or had you updated the oil pump drive etc?

Believe the crank angle sensor from a 34 is different to a 32 and the end of the crank is physically different to suit

This being why there is one PowerFC for a 32/33 and a different one for the 34.

Sure someone could fill you in on the other differences,

or correct me if I is wrong.

LOL i pulled it back from 5th to second by mistake from about 255kph. was well over 10k rpm showing

And to the old girls credit she is still running with no oil pressure, not to mention it had over 100,000kms on the engine anyway.

Thoughts were to remove this damaged engine and throw another stocky with the 2860 turbos in for the next race meeting while the damaged engine is at the rebuilders. i have about 2 weeks and not sure we can get the engine rebuilt in time, the builder has a few in front of me to complete.

you are kind of right. GTRs don't have a crank angle sensor. they have a cam angle sensor. The camshafts are slightly different, and the cam angle sensor is different. Yes the crank is a little different too, but that has nothing to do with the sensor, it just has larger 'flats' to drive the oil pump gear (which presents no problem).

that is all I can think of off the top of my head.

yep oil pump drive failure!

But very lucky, no damage to the crank must have been circulating some oil at least. All the bearings were in good condition a light polish on # 1 big eng gernal and back in she goes.

Not a nice job getting engine out for the first time with a pull type clutch

      R32 only blows hot air

      By Duncan · Posted

      Not really, but the heater box is pretty simple mechanically....if the door is one way the air bypasses the heater core and if it is the other way it goes through it for warm air.  If you are sure the actuator you moved manually is for the heater mix (there would also be one for output air direction) then I'd take the heater box out and see what is happening (you'll have to regass and re-coolant the systems afterwards) BTW pp724 onwards from the GTR workshop manual cover the system in good detail, it is probably worth checking. I think the IAT sensor might be a problem electrically for getting cold (if you got 24 error code not -24 it thinks the incoming air is -50c) and it covers how to test the sensor (although most likely it is either not plugged in or a wire is damaged)

      Use the GKTech subframe bush and bring your subframe 10mm closer to the chassis. You'll need to fix an exhaust hanger to suit. One of the best mods I've done.

      Wires cut underneath shifter cover

      By Duncan · Posted

      You'd really have to pull it apart further to know, it least you can be confident that the one heading to the back is not connected any more. There was once a ground on the shifter seal mount too, your head unit issue could be that simple

      Perfect, I'll get to it this winter then at the same time as I weld on my anti squat kit.

      R32 only blows hot air

      By SeanR32GtSt · Posted

      Alright so my 32 only has one temperature no matter what degree you set it to. I’ve tried disconnecting the servo motor arm and moving it either direction and got no change. I’ve fixed the leak in my AC and re charged it and with it on and clutch engaged it still blows hot even though the low pressure pipe going to the firewall is ice cold. Both heater core hoses are hot while running as well. Diagnostic code showed 24 for intake air temperature sensor. Anybody got any ideas?
