The Turbo update manual states the following for what it's worth.

"The following is a list of deviations for the turbocharged 3.1l V-6 Grand Prix engine. Unless noted below, all torques, general data and dimensional data are the same as the LHO base 3.1L V-6 engine."

The "deviations" listed after that statement are only about the different oil pump, so the NA 3.1 crank should have the same specs(??, I guess Jud, Jeff, or someone else that has compared NA vs. the Vin V crank could confirm that for you though).

The NA crank specs should be on the www.60degreeV6.com board, but if not, I can take a picture of the page from my service manual for you.

does that reluctor ring affect cam/ignition timing?  if so...how?  i'm not familiar with this....

The TGP distance between the slots is .180, the N/A is .105 so the difference is .075. One degree =.0506 of the cir.  1  1/2 degrees is the difference.

Doesn't chang came timing, cam is installed in relationship to top dead center of usually #1 piston.
