alternator nut: 108 Nm / 80 ft lbs
water pump bolts: 14 Nm / 10 ft lbs

then again, the service manual says 15 ft lbs + 90* for the crank pulley. assuming that equates to 94 ft lbs, the torque specs are correct

I think you'll find that means torque to 15ft/lbs then turn the bolt a further 90 degrees from there. A lot of modern cars have bolts that are tightened by degrees instead of a torque i believe.

Where did you get them from and how much they set you back?

yes...... thats why im saying if it equates to 94 ft lbs, then the other torque specs are to be trusted

You can get them online from one of the most trusted websites for this car:http://ft86speedfactory.com/go-fast-...234b62f0a3a540

They cost $345 without shipping and handling, I don't know what he got them for, but there is also another kit that gets similar performance:
http://ft86speedfactory.com/tomioka-...234b62f0a3a540

but costs $316

The latter is 0.64 lbs heavier not that much weight still and won't make as much of a difference but it should be noted, also tomioka apparently dynoed them and gained 10 WHP which I'm not so sure about pulleys do free up horsepower but not that much, the gains from both of them will be similar and anything that lowers power loss and load on the motor is a good thing.

Looks like it mate. Tomioka looks like they have the Alternator and Water pump much lighter than the competitors. hmmmmm I will investigate to see if they sell it separately.
