good commitment, results and thread and excellent work from Yavuz as usual. For those wondering, a dead stock rb26 has the same CAS issue, although in my case we just lived with it (no choice in a p

Eww K-Sport...the other ones are ok...the ones with the twin bolt bridge. I just hate the look, but they do seem to work well. But would still rather 6 pot Alcons on 380x35mm rotors

Hey Paul,

Did you sell that carbon shaft? or still have it? did you get it balanced? or didnt need to?

Hey man.

Still have it in the garage. Got it balanced by some mob, put it back in. It was better but not perfect. The stock one is back in the car now. I sent an email to ACPT and got nothing back. To be honest I forgot all about it.

Great stuff Paul, and those data logs are interesting. Has me wondering if anyone has thought of putting a dynamic tensioner on the timing belt to try and keep the cams more stable.

The EJ20s uses a high tension spring loaded tensioner on the slack side of the belt to take up the belt stretch when the engines RPM accelerates. It makes sense for those motors as the belt is a lot longer than an RB26 belt. It would be worth looking at how the 1UZFE handles belt tension too, as well as they have a crazy long belt.

Ian, I remember you saying something about te EJ's at the Nats.

Thats a good little something I can do when it's on the dyno next. Take a short movie with the Cam gear cover off to show how much the belt flops around. It's actually quite disturbing! Out of sight out of mind right? pinch.gif

When is it going back onto the dyno Paul ?

Looked at mine the other day and contemplated sending it back to Oz but common sense took over as I reached for another beer and shaft was thrown to back of storage shed.

Paul head is not far off. Machining started on other parts.

Very interesting thread !!

Within the next few weeks. Just to turn the EBC on and screw some boost into it. See what it makes before the new head arrives.

HKS Vcam? I'd laugh if that allowed you a choice of 3 gears for any corner!

Sell it Marcus. Ebay that shit. I felt the difference and it was awsome but it didn't work as it should!

Can't wait for this head! Bring it on!!!!!!!!!

Oh. Don't get me thinking. VCam would be UNREAL! The difference between RS's and -5's was just amazing.... V cam ontop would be unreal..... What about a 3.0, V cam and -5's.! Say hello to area under the curve!

      The markings on a balancer are on the outer. The outer is separated from the inner by the rubber. The outer and the inner can, and will, slip against each other as the balancer starts to fail. Put a new balancer on it.

      RB25DET NEO R34 timing belt

      By JC71 · Posted

      I just replaced the timing belt, along with tensioner, idler, water pump, etc. all the front end engine stuff with all new stock Nissan parts on my 98 R34 GTT that I just recently got, so glad I did as the belt ,tensor, idler and water pump were all original to the car with over 161 Km and looked absolutely terrible, honestly I cant believe the belt has not broken, luckily I have not driving the vehicle since I got it, and only have ran a few times because I've been restoring it over this winter. I turned engine over by hand and lined up all the timing marks from cams, to the head (plate behind pulleys), and crank to  oil pump block mark, as ran fine, but had a lot of front end noise. the idler sounded like gravel and the tensioner had to no tensor left on it at all as it appeared the spring had rusted in place due to a waterpump leak over the years. so the timing belt was very loose on the left or tensioner side. Never the less I turn engine by hand until everything lined up even with the marks on the original belt. I remove everything making sure not to rotate anything, then put in new tensioner,  idler, made sure all marks from belt matched marks on the pulleys, cams and crank alike and all marks from crank and cams to head and block were perfect. I slowly turned by hand and everything lined up on the cams and crank to the head and block every other time, as proper. all looked fine until I put the lower timing belt cover back on, then the  harmonic balancer, at this point before torqueing the crank bolt down I noticed the timing mark on the lower cover to the harmonic balancer is off. I think the marks on the harmonic balancer and in 5 degrees, from 0-20  and it should be at 0, but some how its around -2.5, not enough for a belt notch, and there is little play in this cover to the block. The key way and key are perfect on the crank and slot in balancer is perfect, no play here, and the cams and other timing marks seem to be on. Is this something to be concerned with or will it be fine. maybe just this way due to a new stock Nissan belt?? slightly tight and will stretch a hair??? I marked the CAS before disassembly and know it should be set to 15 degrees BTDC or so at 650 rpms per engine decal. so do I need to worry about what appears to be a slight retard of the mechanical timing? or will this slight difference be compensated when I adjust my CAS?   appreciate any insight.
