Emailed some info to another SAU member and thought id post it up here aswell:

This shifter is used to prevent missed gear changes mainly in dog engagement gearboxes.

I messed up once and it cost me.

This is how it works.

The outer aluminum shaft of the shifter is spring loaded up and down, the first picture is in street mode you can freely shift into all gears.

Second picture is when its in drag mode, the outer shaft drops down and is ready for the 1st to 2nd shift.

Once the shifter passes the step it cannot jump back up and into 1st gear and can only go to 3rd.

In drag mode the shifter cannot be changed into 5th or reverse.

The front of the gear knob has a small U shape cut out, this is for the grub screw to fall into when its in street mode which holds the out shaft up...

The shifter has a aluminum spacer that bolts to the gearbox that raises the pivot point up like normal quick shifter... In a way is almost like a straight line shifter just pull it back and push it forward...

For normal use the standard shifter is much easier for daily driving with the dog box, it did take a little bit to of time to get the timing back for smooth operation of the dog gears but not to bad.

Sorry for the low quality iphone pics....

    • Have you put an aftermarket oil pressure gauge on and verified your oil pressure?   Noise being on the block, on exhaust side, how high up the block does it seem to be? It could be the VCT system getting cranky, especially if it's mainly at idle, and when warm, as that'll be your lowest point for oil pressure. Could be showing that oil passages / VCT solenoid are blocking.
    • Well, hydraulic lifters will get noisy if they are dirty/fouled in some way, and exactly how that manifests will depend on exactly what schmutz is where. There is a procedure on here somewhere for dismantling and soaking/cleaning them. Replacing them with new is about 50% of the work and about 5% of the money!
    • Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers  
    • This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?
