Hey. I have functioning motor mounts that I made for my 142/OHC setup. They used the stock mounts and brackets on the subframe. Stock mounts allow for way too much movement, and since I'm putting a 16v in such a tight space, I can't have all that.
So, I'm making mounts out of torque rods. My dilemma right now is whether to bolt a bracket with tabs for the torque rod to the frame rail, or to weld tabs directly to the subframe.
Pictures:
Ideally, I'd get the mounts up onto the frame rails, to get the mounting points as wide as possible. Also, being able to drop the subframe without supporting the engine would be neat. My concern is with drilling swiss cheesing my frame rail with four M10 holes. Will the front of my car snap off? The holes would be between the subframe bolts, so kind of a low stress area. (maybe?)
If that's a no-go, I could weld the tabs onto the subframe, but then the points aren't as wide and my engine is still on the subframe. I guess I could also weld the bracket directly to the frame rail, but I'm not sure how thick the frame is, and it might not be a good match for the 3/16 plate that the bracket is made out of.
Any input? If you've made it this far, I'm impressed. Nobody cares about 140s.
