Hi All-
New member here. I have the engine out of my '73 2.0 to address some fluid leaks and noticed that the engine mounts were unusual. Going through old paperwork, I found that a PO had installed "Club/Sport" engine mounts 15 years ago. The car is a '73 with stock side-shift trans and cross bar with the hole in it for the trans linkage. But the engine is mounted to the crossbar with solid aluminum blocks and the crossbar is mounted to the chassis with rubber -- similar to the older style tail shift factory mounts -- instead of the inboard rubber+outboard solid mount expected. I'm inclined to return it to stock, but I'm trying to understand the purpose of the "Sport" mounts. Online searches suggest that 911 "Sport Mounts" are used somehow for /6 conversions, but I don't know why PO changed from the stock mount with the factory 2L engine/trans. Thanks for your help. FWIW, pic of my baby is attached.  |

Your setup makes things worse, especially on the track. (IMG:style_emoticons/default/shades.gif) Thanks. So, are you saying that the engine would move more with the rubber at the ends of the crossbar than it would with the rubber inboard? On which axis? (Pitch? Roll? Yaw?) I'd guess that it would flex less due to the longer moment arm between the rubber points (unless the outboard rubber is more flexy than the inboard rubber...) Thanks again. I think I'm gonna return it to stock as you suggested. But, I'm just trying to understand why this mod was ever made in the first place. |
