Hey guys

Have a problem with my 32 gtr.

Started the car and no belts or fan or the harmonic balancer where moving so I shut it down immediately.

The next day I cranked it with the CAS unplugged so it wouldnt start and they started moving again

I still didn't try starting it as I know something is wrong.

The harmonic is loose even though the bolt is tight.

I can wriggle it foward and back a bit so it has play.

Now I try taking the bolt off and even while it's in 4th gear but it spins when I put heavy load on it.

I was going to try a rattle gun.

Any suggestions or anything would be a massive help.

Don't chuck it in gear and try to undo the nut, you'll f**k your drivetrain. pull out the starter and jam something(screwdriver etc) between the ring gear and gbox housing to stop the crank from turning.

32 GTR is extremely tight to work around, but fitting a ring gear stopper takes only a few minutes, well worth the time.

With the battery disconnected, use a 3/8" drive 14mm universal long extension coming in from above the alternator.

Remove the top bolt completely before starting on the lower bolt.

Swing the starter clear, no need to remove any cables it will jamb up there nicely.

Fit the ring gear stopper.

Mine has one hole completely slotted so I can engage/disengage the stopper by loosening the bolts and then rotate it out of mesh with the ring gear.

I can fit a cam belt, spin the crank a few times and re-engage the stopper, all very quickly.

Installation is just the reverse. Fit the lower bolt first and nip it up before offering up the top bolt via the long socket.

There's a cable clip under the head of the bolt to add to the hassles.

There are special "C" spanners or "half moon" spanners designed for starter bolts but a socket + long extension works much faster.

I can assure you, there's a lot harder jobs on a 32 GTR than fitting a ring gear stopper.

i was thinking of welding the keyway in and filling the slot as it has almost doubled to the size of the key way.

Either either way im selling the motor,all bolt ons,loom ECU for 2k if anyone is interested.

I have a built motor and i cant be bothered wasting time on this motor

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.

      Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
