OK, so this started with the wifes car being out of oil. Engine seized during a high rpm shift. The only damage I found inside was the rod bearing grabbed onto the crank and sorta just stuck themselves on, luckily they never spun and I was able to just polish the crank and replace the bearings. The oil consumption was the rings, the oil control rings were completely carboned up.
When I went to reassemble using the manual to line the timing marks up, the engine hits a valve. Rechecked several times, its timed right. So I got to wondering if the sudden seizing caused the crank sprocket to slip or bend the keyway, I was shocked when I pulled it off to find the crank and sprocket have no keyway or any way to locate the position to the crankshaft.
This comes to my question, how do you put the crank sprocket back on in the right place??
First one I've had apart and its a really well built little engine, but not a lot of info around

Ask a builder of these engines.

I think I have it back on right, but do you know a builder of these engines? I emailed KDMtuners but never got a response.
I'd like to know exactly how its done

I believe this is becoming rather common. The MZR in my Mazda 3 is the same way. There are special tools that hold the cams and crank in place to preserve cam timing. They were surprisingly inexpensive.

Yeah I've done that on other engines and brands, but I can't find anything for this one. So I put it back on making sure the balancer ended up lining up with 0 with the timing all lined up and the sprockets referenced to the cylinder head surface. So I think I'll be ok, waiting for a couple crank cap bolts that are back ordered or I'd be able to tell you if it worked.
