Pepsi or Coke?

Well Mr. Nickleye, I got this out of one of your threads in the FAQ's:

And I quote: In 1988 "Toyota began using the "7M" crankshaft mid-year, with dual counterweights to improve smoothness. The extra weight also caused the redline to drop from 6500 to 6250."

"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.
