    Well done for having the courage to start this thread.  There is another Australian based performance orientated forum that has some very deep conversations on similar matters.  There is a lot of sharing and advice that makes one recognise that they are not alone.  Experience is showing that there should be a limited access subsection for discussion on such matters to limit public exposure (trolls and vindictive people etc).  Certainly it is a very healthy discussion to have. All the best.  Lincoln.

    Curious cam timing.

    Long time reader.... first time pulling one apart.  

     

    I am giving the GTR a birthday with new timing belt (and braces).  I was told car had HKS 264 cams and under the covers there are cams stamped with "HKS" but no other markings ("RB2" is cast into the blanks).  Curiously, the inlet cam (greddy cam sprockets) is set to 10deg advanced and exhaust is set straight up.  As I dont have a long nose dial indicator to hand and I am lazy, is it conceivable that someone (who knows what they are doing) would end up with these settings on a dyno?  I was thinking of returning them to typical +4/-2.  Car has R34 N1 turbos that I want to run about 20psi.

     

    Thanks Lincoln. 

    Os Giken Clutch - A Time Is Money Problem.

    Hi all,

    I have a grumbling just started in the release bearing and want to replace the clutch plates, rear main, input shaft seal at the same time.... I have a surface grinder at work so should be able to re-use the pressure and intermediate (twin plate) plates and the flywheel...

    As I want to smash it out over a weekend I would like to have the plates already but am finding some holes in my knowledge. I have an invoice from the previous owner from Unique Auto Sports that shows "one reconditioned OS GIKEN twin plate" fitted 2009 and car certainly rattles like a twin plate :).

    Car in a VSpec 32 06/93 which I am told is a pull type clutch. My questions are;

    1. New plates from where?

    2. Do OS GIKEN do a pull type clutch or am I expecting to find a pull-push conversion in there?

    3. Release bearing? I think it uses a standard GTR one but the above question will effect.

    Thanks for any help.... happy to buy off anyone who provides the correct information.

    "Then answer to that brain bender is that I am referring to light loads and off boost drivability. At idle and low speed cruise, less atmosphere caused the map sensor to move about 500 on the PIM scale towards 0psi. This meant that the tune that was stable at sea level would end up rich when at altitude.

    It didn't matter what map sensor I used. Apexi 3 bar, apexi 3.5 bar, GM 3 bar. They all handled atmospheric change terribly. In short the rate if any that they did work differently did not even remotely work with the FC."

    Yeah nah brain still broken. Does not compute with my thoughts about map sensors. I understand aftermarket ecu's needing barometric compensation on NA cars when running a tps vs rpm map. But barometric compensation over a djetro map which already runs manifold pressure vs rpm map has me stumped.
