TPI torque settings

Hi all,

Could anyone please tell me or point me in the direction for the torque settings on a TPI engine? I'm after settings for the plenum and runner bolts, throttle body etc and various devices like IAC, temperature sensors etc etc. I googled thirdgen.org but didn't find anything.

On those bolts, I've always done it by feel. basically just snug them down, then give it a little bit more. Obviously with plastic parts a bit less is appropriate than on all metal parts. For example on the runners, throttle body etc you can crank them pretty hard (you are using hand tools here right? don't be using 1/2" drive impact guns

). Give any plastic things (sensors etc) an extra 1/4 turn after they get snugged.
