Need A Pic Of Stock R33 S2 Turbo Wastgate

Trying to read between the lines here , are you attempting to beat a boost creep issue by doing this ?

A problem can exist where people think the waste gate acts as a pressure relief valve which its not intended to do . It is possible at times to make the situation worse by giving the exhaust manifold pressure greater area with which to act on and force the flap valve open . If exhaust manifold pressure (turbine inlet pressure) is the problem the usual fix is a larger AR ratio turbine housing or smaller compressor / compressor trim .

it's a stock turbo, but it creeps up to 10.6 psi. How else can i cure the problem? I tried to controll boost any which way i can, but if you connect it directyl form the IC i get 10.6 psi, with the gate fully open, still 10.6 psi. I have a stock BOV which has been pressed in a little, about 5 mm, but the problem started to occur long before that was done, actually it was just after the dump was changed. So i pressume boost creep is due to the wastgate.

Can somone elaborate. I have read heaps of pages on the internet, all regarding creep, and it all point to the wastgate.

    • I still have Garrett parts to build GTX2860 if interested. 
    • I reckon coilpacks too. Mine went at exactly 100,000kms
    • In the process of riding up my car lol, am trying to get a decent looking oil cap. Some say they are fine to fit all RBs or even all Nissan, others like a stock GTR oil cap say rb20/25/26 but they won't fit a neo rb25. Is this due to the stock plastic engine cover or is there something else different?
    • Well Coolant pressure increased significantly under + boost.  Enough to bypass rad cap Coolant pressure normal under low load conditions and no overheating. Head off and you can see where it was bypassing the cylinder ring to coolant chamber on both head and gasket. Head cracked tested and serviced, all good. Block was only visually inspected, so please god ...  let that be ok   You could argue that is a Head gasket failure but it was still very much a complete unbroken gasket. So suggests some stretch on the factory head bolts. I know others that have had the same as above and not even taken the head off, just put in studs and  continued on for years.  
    • Just jumping into this one, someone's decided to try get into my 34 by bending that top door window trim back.  Anyone know how to remove these? Going to try and bend it back properly and sikaflex it... Cheers
