Did you have the cams out?

If you did - did you make sure the cams could turn in the bearings by hand a bit each way reasonably easy(without belt on and hitting valves on pistons)

If the cam was binding up and the belt wont snap cause its good somethings gotta give!

Sorry to hear about it and hope you resolve it without too much expense!

sucks to be the people who said i f**ked it

heads fine as is the bottom end

no chips or cracks in the valves from what i can see

chill out mate. In many cases it does. Internet diag. is a hit and miss affair and they are only giving advice.

.

No belt should whir loud enough to hear it from inside the car driving, if yours does this it is TO TIGHT!!!!!

Sorry bout the failure you have there but diagnosing it from the internet is going to be really difficult. It could be anything from losing oil from front cam bearing which in turn snapped the camshaft, could be belt to tight, or as mentioned bolts could have been lose casue a slack that impacted a brittle part and snapped it.

Keep us all posted with pics, and what you find this is the first ever casue I have seen that isnt immediately obvious, and breaking this at all is pretty rare. Good luck pulling it down they are a bastard you need Japanese school girl hands, i swear nissan had midgets putting together GTR's.

    • I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
    • 310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
    • The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.
    • Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.
    • @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
