Is this behind a turbo motor? With mods? A manual trans?
I've gone through the usual list of options on mine.
- stock mounts - hit boot in 1st gear once and at least one is going to be ripped apart
- poly mounts - do you like buzzes and rattles? That's how you get buzzes and rattles. Didn't rip apart the first time it hit boost in 1st, but maybe... 10th time? One was ripped in half a week later
After that I used a combination of a passenger side OEM/Volvo diesel mount and some shorter/stouter mount from a Dodge pickup on the driver side. Shorter because I needed to lean the 16V head over a little bit away from the A/C lines on the firewall, stouter because it was used in a pickup with a V8 and a low range transfer case.
(1993 Dodge W250 V8 on Rockauto - cost a whopping $2!!!)
But at that point I was tired of messing with motor mounts, and even with 'strong' diesel and pickup mounts, I started using a ratchet strap.
Which was as easy as pie to do. I just ran it from one of the engine hoist loops (front and back of the bolts that hold the intake manifold on) over to the driver's side shock tower. Hooked it, ratcheted it down modestly tight, and never broke another motor mount, even with roughly 350 whp (at times). 'Preloading' the motor mounts with strap tension in the 'go' position also just helped the whole drivetrain feel less sloppy as the throttle went on and off, the stick shift wiggled around less. And the strap adds practically no vibration either.
