Just throwing up a question of interest, we all are adviced to do the timing belts every 100k just wondering if anyone out there has gone the full distance with there stock timing belt until it snapped or had a problem due to the tensioner bolt , interested to know how long they actually lasted

every 100,000km or 7 years is the general rule. The rubber degrades over time no matter how low kilometres you do. Most people here have probably had their skylines reach the 100,000km milestone with the factory fitted timing belt, 89 GTR for example that changed it this year.. that's coming 20 years old.

Timing belt snaps and the valves smash into the piston, and takes a a piston or 2 with it.

Tensioner/idler pulley seizes, the belt is locked in place and valves are smashed into the piston, and a takes a piston or 2 with it.

i changed my belt at 100k but didnt do the tensioner/idler pulley and ive gone 35000 since i changed im planning to change it at prob 180k wondering if itll last

I had one fail years ago - previous owner did the timing belt, didnt to the tensioners i found out afterwards...

This was on a 120,000 km RB20.

18 of 24 valves smashed from memory when the tensioner let go

Do not risk it, its stated as a required item for a reason.

Did mine at 130,000km, belt was very loose and brittle by the looks/feel of it. You must change tensioner and idler as they are designed to go at around the same time. I should have done service at 100,000km. I suppose I was just lucky.

by the sounds of it most people have changed both, the only reason i left out the tensioner and idler were when I inspected the bearings at the time they were fine , hrmm wishing I had of just changed them

i did a service on a r32 gtst and it had 190000 on it and the idle pulley had been broken for at least 10000 acording to the owner and the belt still hadnt let go for some reason i couldnt believe it

hmm, do you guys reccommend oem belt or the gates belt? also where can i pick up the tensioner and pulley from?

also is there any difference to r32/33/34 /rb20/25/26 series 1 and 2 etc?? looking to pick up these parts soon

oh and part numbers too!

The genuine oem Nissan and Gates belts are about the same price, I chose to go with the genuine belt as Nissan's genuine parts are really good, only downside to the Gates belt that I know of is that they are rather noisy until they are run-in

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      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.
