Motor mount.

Ok, I asked in the modifications section but I guess not too many peole saw it.

I'm going to be doing my own motor mount install soon, does anyone know what the factory torque spec for the MM bolts is??

Assuming you mean the number one engine mount: this is what the manual tells me.

A type: 72.6-90.9 N-m {7.40-9.2 kgf-m, 52.6-67.0 ft.lbf}
B type: 93.1-116.6 N-m {9.5-11.8 kgf-m, 68-85.9 ftlbf}

A Type: top of bolt head is blank or has a single dash (-) in the middle
B Type: top of bolt head has a number 10 or two dashed aranged so they look like the hands of a clock showing about 10:00

The A/B reference is for the normally aspirated engine. The turbo version has numbers for both bolts that match the Type A values.

This is the dealer repair guide for the MM recall.

Tighten the No. 4 engine mount securing bolt (M14, one piece) to the following specified torque. Tightening Torque: 129.9 – 152.7 Nm (13.3 – 15.6 kgf-cm, 95.8 – 114.8 ft-lbf)

the number 4 engine mount is the tranny mount that the recall was done on but it might be the same
