Not enough oil pressure from hydraulic lifter gallery(being low pressure, as opposed to getting feed direct from main oil gallery).

I think the internal vct mod is a bit of a hit and miss some say it works others say it doesn't.

All I can say is that it didn't work for me, and its a head off job to drill and tap for a vct feed line.

Take a risk and find out if it works for you :P

So you ended up wanting to go the 35R? What made you change your mind? Just curious...

Ive currently sold my GTX and just purchased a 35R to throw on there.

currently she only revs to 6500 rpm as anything over that it just stops making power, though still enough to run a 12.1 on 18 inch ling longs.

With the 35R on there I can rev it just that little bit harder and gain that extra 1000 rpm. +fix the vct issue and I am back to where I started in terms of response.

Its win win, fix vct and get similar response to the gtx without vct + have that extra 1000rpm head room to get down the 1/4 quicker.

      Need to see other side of PCB in that area...ie; I don't see any thru-hole mounting, just soldered vias (smd zeners in SOT23 have 3 legs but only 2 are used, as reflected by PCB tracks)

      4 to 5 is fine. It will be slow, but that's better than blowing turbos. I don't have a PS pump idle up solenoid on my car, because... I think when we put the Neo in we retained my R32 lines. But.... From inspecton of the R34 vacuum hose diagram, you can see that the solenoid needs to be connected to the turbo inlet as source of clean air) and the plenum (as source of vacuum - which is the place for the air to flow to to cause the idle to increase). So 3 to 1 is VERY WRONG. 3 should go to either the turbo inlet, or the plenum. Follow the other hose from the PS solenoid and if it goes to the plenum, then your 3 goes to 2 2 would also serve as a bleed port for a boost solenoid.

      Pull them out and pull more apart. You can't do shit with them still bolted to the floor of the car.

      Yes it is. ZD1 is on the other side of the board. Where ZD1 is marked is clearly opposite a 2 pin device. Our 3 pin device here is not a ZD.

      Tein Circuit Master- rebuild worth it?

      Alright, a little update on this... I called Fulcrum, who used to be the distributor in Australia. No Bueno, they don't service them anymore.  Called shock works, who don't service them but offered to dyno the shocks for performance, and suggested DNA in Sydney might service them.  Called DNA, who also do not service them and basically said they try to steer customers away from tein for this exact reason these days- there is just no support for them anymore apparently.  Both SW and DNA said they are a not necessarily a bad product, but they just don't service the brand or know anyone who does service the brand anymore.  So... I could keep calling around but at this point I think I'll probably just spring for the shockworks product, unless anyone here knows anything.  Cheers 🍻
