Installed a throttle body space which switched out the studs for bolts, does anyone happen to know the torque requirements for bolts? At the moment they are tightened by the wrench and not torqued.
Hi,
This is using the stock DBW TB with a spacer plate running longer than stock fasteners.. No additional spec’s?
As I’m uncertain of your fastener material or additional length, I’d stick with OE spec’s, after preparing the o-rings, gaskets (if any).& seal surfaces.
Be 100% certain no binding exists between TB butterflies and spacer bores before starting Engine. Last spot you want sticking.
First pass of two after bolts are just snug moving in a crisscross pattern, torque to 7.4 Ft/lbs (or 89 in/lbs,10NM).
I run an additional 1/4 turn, depending on fasteners and length.(?)
Good luck!

Thanks! Appreciate the reply and it looks spot on. The setup is the factory o-ring / throttle body spacer / gasket / throttle bottle. New hardware replaces the factory studs.
I found the following online if anyone every needs a reference:
