ACE A350 header Bolts/nuts torque specs? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Plumbus · 12-07-2020, 09:22 PM

Hey fellas, yesterday thanks to a bunch of you cool guys I was able to finish installing my ace a350 header. I am doing the heat cycle/retighten method to prevent the hardware from falling off (as the ace headers are so well known for), but I could not find the torque specs for them.

What are the torque values for the header/overpipe nuts, for overpipe/frontpipe bolts, and for header/engine nuts? thanks

Somewhere between "pretty tight" and "plenty snug"

Well I went ahead and tightened them good'n'tight. After heat cycling the car a few nuts were actually loose, so it's good to know to retighten them. The engine mount nuts in particular were completely loose, which is probably why I heard some clunking noises during logging. The header to OP nuts were also a bit loose, hopefully they stay nice and tight for good.
