Ridal Posted September 19, 2012 Author Share Posted September 19, 2012 Perfect. That's a really good point. I'm sure people have had some success with the urethane sandwich but it sounds like solid engine mounts with rubber gearbox mount is the way to go. I can always change back to factory if they are hell. Thanks for the up to minute ruling to. Simon, would solid mounting not help the drivetrain feel more positive? I may end up going for some harder rubber mounts but I want to try solid first and go from there. Fortunately they're very easy to change.

Raizer Posted September 19, 2012 Share Posted September 19, 2012 dont get a urethane/nolathane bush and run a bolt right thru the mount/xmember/bush like a lot of people do, specially with rotaries. if you are going to do that use a solid bush, steel or alloy, if using a compressible bush, the bolt can never be 100% tight and will come loose or oval out the mount holes Does that still apply if the bush has a steel crush tube in the middle? Guys have been using "world cup" crossmembers in Escorts for decades now Quote Link to comment Share on other sites More sharing options...

Borgweiser Posted September 21, 2012 Share Posted September 21, 2012 ^ makes sense to me, kinda. solid mount = transfer of vibration somewhere not wanted in my experience. I would personally try other options.. Quote Link to comment Share on other sites More sharing options...
sentra Posted September 21, 2012 Share Posted September 21, 2012 it just gets dissapated by suspension. ive done it on 3 cars...two bridgeport rotarys and one crummy bfmr with lumpy broshafts. it just gently sways side to side a little bit at the lights, its hallerious, the hunnies love it, you can rev it and it will sway like the movies. your coilover/cuttys nhv will waaaaaay overpower it. i guess if your dash was made of cornchips...or your talking about a p76 engine like borg!!!

flyingbrick Posted September 21, 2012 Share Posted September 21, 2012 I would not feel comfortable solid mounting the engine AND gearbox as it then becomes a stressed member. I have no idea if its actually a problem but you could exert some serious force on the gearbox mountain points should the chassis flex Quote Link to comment Share on other sites More sharing options...
Borgweiser Posted September 21, 2012 Share Posted September 21, 2012 i guess if your dash was made of cornchips...or your talking about a p76 engine like borg!!! First of all, it's you're.. Secondly don't associate me with boat anchors, only good thing about the p76 is they rusted quickly to death. also, rotaries, hunnies- chicks are easily impressed. We are taking about a 5K here, surprised it's got enough grunt to break an engine mount. Quote Link to comment Share on other sites More sharing options...
JoKer Posted September 21, 2012 Share Posted September 21, 2012 has anyone suggested giving it a rub yet? Quote Link to comment Share on other sites More sharing options...
