building my engine as we speak, mine is a 88 turbo and my crank says 6M. If i remember it is in the front side (timing belt side) on one of the counter weights

"The 86.5 Supra had a new block under the hood, although it used the crankshaft from the JDM MKII's 6M-GE"

So from 86.5-88.5 ALL supras came with cranks from MKII JDM 6M-GE's.

And from 88.5 on they came with true 7M cranks.
