Very cool! I had a good source for JIS fasteners (the style Toyota uses with a flange hex head), but some of them dulled very quickly in the engine bay.Not today but yesterday... piddling around trying to get the right studs, nuts and bolts to put her back together. Ended up powder coating the exhaust manifold because it goes back on first. It's gloss black. Next was the turbo heat shield which I may not use in the end, but for today, it was powder coat. "Black Chrome". It looks sort-of all-right, not sure the color came out how it should have. My oven is for small pieces, when I do these, it's in front of two 1000 degree gas heaters... standing there with an infra-red thermometer, trying to hit 400 all over Not easy.

I have all the Harbor Freight colors and three or four custom colors from Eastwood, but I'm trying not to go crazy on the colors, much prefer a good finish to a colorful one. Not much experience with powder coating, wonder if something like this turbo shield will continue to change as heat is applied. They warn you not to use an oven for eating after powder coating because the powder re-activates when you heat it...
This car has been apart for several years. All the original nuts and bolts were caught in containers based on their function. I also took went to Fastenall and purchased quantity of everything we could identify with the hoped goal of all new hardware. I still find myself at the local Ace Hardware regularly getting this or that. Little things like the upgraded exhaust studs. There never were any nuts for them. Ace. See you tomorrow.
Spent 30 minutes at the hardware store before asking for help, only to find nothing. Even with help, and a friendly customer, we found nothing. I didn't specifically check the American sizes, but my one sample nut only fit 12 MM thread, didn't come close on 7/16;Very cool!

Are you using normal hex head with a washer or did you find bolts with the integrated flange?
Powder coating looks great to me. Hard to make that heat shield much worse than normal. I'd say it's a huge improvement.

The studs are from the 7/16 upgrade kit from Drift Motion. The find thread end of the studs is 12 mm x 1.25 pitch.
If it proves to be 12 mm 1.25 pitch. DM sells those nuts as "motor mount nuts", and they have an <snip>
This a very well put together video. Very professionally done. Nice workInstalled the Arizona Performance BBK on my MK3. The car hadn't had fresh brakes on in... 10 years? Going from worn and tired brakes to this 4 piston setup was unreal. (Not done today, but uploaded within the last week)
Thank you, and yes, I want to run it on the stand. There is still a lot of work to be one on the Speeduino ECU, all the sensors and wiring, etc. It's been six or seven months since the head was put on, and the valves haven't been adjusted yet either. I try to do each step as properly as I can, but, still, you never know, did you get everything right? Also, did other things, like the media blaster, or the metal fabrication, cause contamination. The engine is usually covered, sometimes in a big plastic bag, but, I still worry. It's got to run on the stand.I like that stand. Need to hook up some fuel and battery power so you can break it in and tune it before it goes in the Supra
@plaaya69 Got to thinking about that... running on the stand... and shooting in that direction, the things I'd have to do. My oil pump was modified and primed with grease, but, there's still no oil in the crankcase. There are still holes for various things, turbo oil return, etc. When the machine work was done the tolerances were set to use synthetic 20-50, 2 gallons of Castorol on the shelf. I added one and had two oil leaks. The simple one was the drain plug, it was never tightened. The other was the oil pan, one of the four bolts on the timing gear/end plate.... <snip> The engine is usually covered, sometimes in a big plastic bag, but, I still worry.

Great idea. A fog machine under the engine bay and some dim flickering orange/red lighting under the hood to look like a small flame would be a great touch. If you really want to scare em hang some blown 7m Headgaskets by the door and you will have the scariest house in towni did my halloween setup

where did you have the filter at in the system?Has anyone installed a bypass filter to their coolant system?
I tried this over the summer, so only a few months and not many miles. (~2,000 probably)
Really surprised as to how much crap it caught in the system.
Mind you this was installed after a recent flush and filling it with new Toyota Red Coolant.
Most of the components in the coolant system are also new.
Have a look:
I knew something was in the filter after pouring out backwards what was inside.
The grey liquid in the container was what came out, lots of weird floaties.
I cracked the filter housing open to have a look inside, and wow!
Lots of Grey Goop, I have no idea where that came from.
The filter was clearly getting very clogged as it was starting to deform.
Luckly the inside filter medium was still pink and intact.
I am glad I removed it when I did.
Appears to have done its job, the coolant I drained from the engine was spotless, like it was poured out of a new jug.
The last couple images are what the filter medium looked like after I sprayed it with water and compressed air.
