That will be a rocket.

Managed to snap the dipstick while doing some engine mods (more on that later) and then tried to tack it back together for short term use but the weld melted an unknown amount of metal out the middle of it, so I need to find or make another.

So, gemwreck qld was nice enough to send me this reference pic of the length of the g200w twincam dipstick. So I'll post it here for the internet to archive incase anyone else finds themselves with the engine and without the dipstick and also needs this exact information. 285mm from tip to shoulder and 10mm from the bottom to the low mark and 25mm more (35mm from the end) for the high mark.

Other Isuzu dispsticks, like 4ZE1 (though nobody probably wants to seperate from a 4ZE1) are the same type of construction, just longer, and would make a good donor. I'll see what I can find down the wreckers for my puposes.

We have a starting point, things are running and working.

I would measure the size of the hole the dipstick fits into then see if a local wrecker will let you have a scrounge around for one that fits the hole and if too long that's an advantage. I'm surprised the wrecker that sent you the pic had one of those engines in stock. Their getting old now.

Oh yeah, that one is solved. The one who sent the picture was Elky up in QLD from specialist gemwreck. Good guy. Because he is a gemini guy he had one in his car, but not to spare. I have used him for other gemini parts too. https://www.facebook.com/p/GemWreck-100064048692868/

I just searched generic aftermarket ones and found the longest I could get, and bought that. It was really hard to cut but I cut it and eventually managed to drill the high and low points as per the reference pic so that is all solved. The aftermarket one was "Engine Oil Dipstick For Mazda 2 2007-12 DE 1.3 1.5 Mazda 3 2004-12 BK BL 1.6 AU" for $13 (I search it now and can be found cheaper too) and its not original but it is very long. Worked out OK.

I should document the issue I hit with going boost on 12p. I knew the boost AFR tables are blank out of the box, and I populated them, but my issue was there is also cold engine boost AFR tables and I had missed them. So they were zero and the ECM flipped out (that is, lost all power and it didnt come back even when off boost) with a cold engine. So when takeing an NA tune, populating boost, and adding a 2 bar map, that is one to watch out for and another table that needs base data.

Not hard to cut with an angle grinder. Glad to see you got one.

yeah it was more the drill. it was harder steel than the bit! had to tap it, clamp it, use the drill press. got there in the end but it wanted to spin and spin and spin and not cut!
