Yuh, that's just a sheathed TC passed through a gland.  The screwed fitting at the very top (female part) is the gland seal.  The TC is very short, so it would be trivial to not insert it far enough.  Just loosen it and see if it can be pushed in further.

Finally got the car back. Based on a quick spin everything seems a-ok, no more bubbles in coolant, in fact the overflow is sitting rock steady at the max mark before and after a run now. Water and oil

If your not going to go crazy with the boost levels Stock headbolts will be fine unless you plan on running more than 22psi closer to 25psi Would get away with a head skim and genuine headgasket un

Have you got a new radiator cap? Have you had a new radiator? Go to a radiator shop and get a pressure test then get them to take the top tank off and clean out the radiator or recore as necessary. Yo

According to tampered motorsport website apparently there is a sandown track day on the 11/12. I may sign up for that once I have my car running again.

Some of us other SAU's might join you on this day :) Either that or rexmas pending on the amount of cars entered

Cool, will keep an eye out on both events and touch bases before committing to anything.

Just pulled out the sensor then, it was pretty stuck with the constant heat expansion/contraction. The probe sticks out a good 25-30mm and I don't think it's ever moved since installation (nor could I move it) so it's not the positioning. Also the gauge doesn't move anymore at all (no error light either) so somehow the sensor just decided to die now.

A genuine Defi replacement is like $250 so I reckon I'll try a cheapo eBay replacement next to see how long it lasts.

No.  Take it to IPA (Industrial Pyrometers Australia) or any equivalent place near you and say, "Please sir, make me one of these."  Will cost ~$50.  Will be proper.

Did exactly the opposite, ordered cheapie off ebay, butchered original sensor wire to get the connector, only to find out that the probe itself won't fit through the Defi bung in the first place lol

I was googling industrial pyrometers and a few companies came up, if you've used one in Melb before which one was it?

      Or, the height of the release bearing is not correct for your combo. Start with the bleeding and checking the slave moves throughout its range when you press the pedal (2 person required), but it is possible for the height to be internally wrong too (box back off to measure.

      Yes, there's quite a few things that can go wrong during a clutch install. Very unlikely. I have a similar clutch. They (ACS) make good gear. No, it is not normal. It is possible that you just need to bleed the clutch slave. But the new clutch will also have a more aggressive actuation force/pressure, and so your old slave cylinder might be a bit leaky or otherwise compromised, and not up to the extra force required. Or the master cylinder, same.

      Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in?
