worried about setting cam timing on new motor
it's a bit of a long story, but i bought a BP from a local to swap into my 93. The motor is from a protege. the guy had turbocharged the motor and blown it up, and when i bought it, it was in pieces.
i had the motor rebuilt at a local machine shop with forged internals, and had the bottom end assembled there as well. i recently bolted the head on the motor, and want to get it timed, but i have a small problem.
for some reason or another, the plate that bolts to the motor with the timing marks on it has been cut in half, and i only have the top part. i called the guy that sold me the motor and asked him about it, and of course he doesnt have the rest of it. he told me the timing marks on the cam gears are supposed to line up with the marks on the top part of the plate, but theyre at 12:00. i'm afraid thats not right. the timing marks on the miata are at ~4 and ~8 o'clock.
how am i going to get this thing timed right?!

Just keep referring to the write-up photos on the m.net garage, and quadruple check it.
If it doesn't look right/count right keep pulling it off.
Main thing is to work belt counterclockwise starting at crank, eg:
crank>exhaust gear>intake gear>tensioner
This will make life easier, but still turn it a few time and make sure you're hitting all three marks with 19 teeth still between the gears.
