Got a set of PU bushing but it was too big so I just got a set slightly smaller and sleeve arrived today. Cutting the sleeve tonight and post some pictures tomorrow.
The Toyota OEM mounts for the 1UZ break everytime you take out the engine, even if they're new. I believe they start to tear when the engine is tilted before being lifted.
Can you describe the the feeling before/after with solid mounts? I would rather save a few HP by stiffening the engine. Can you feel the vibration at idle? I mean if you feel 10% w/ stock rubber and maybe 25% with solid... I think I can live with that.
Talking about vibration. If you have a perfect idle, then you'll have some vibrations. But if you have a set of modified cams in there, the whole car will shake and rattle your butt, back, and b**bs at every second. I used to have an exhaust system that's mounted solidly to the chassis and it shook the car like crazy with all of the noises, although I have rubber engine mounts. It was worth a try to know it. I wouldn't use solid mounts in anyway, even for racing.
bumping this to the top, any updates ?
i want to replace my engine and transmission mounts, but dont wat to give Mr T the pleasure of raping my wallet !
A few options..
Fitting solid mounts or welding them solid with give some harmonics through body..
BUT not as bad as exhaust being solid mounded.. Don't solid mount the trans as any body twist can break housing..
Another option is to add another fastener on the left hand engine mount to hold it down.. Some use a modified seat belt ends and fit them to restrict engine lift on that side.. Being a fibre there's no vibration transmitted through body..
Another option is a mount a mid cross member under engine / transmission and add extra mounts .. This is usually done on all out race / drag cars...
Some race rules say you must have these to prevent engine or trans falling on ground IF trans breaks..
Imo adding extra support to the drivers side [left as sitting in drivers seat] is the best performance street option...
Having said that.. In many other brands of cars they often just weld the left mount solid... With hardly any difference.. You possibly couldn't tell unless you knew it was solid...
i dont really want to go completely solid, i noticed someone on here made mounts for the engine, and though about doing the same things myself, but if there is an option to buy at a reasonable price, id rather to that so i can focus my attention elsewhere
I used GM V8 engine mounts they were about $14 ea. Very firm mount, no body harmonics and cheap to replace if I ever break one which I doubt will ever happen. I don't have the part number but the mounts are very common here in Aus. Brackets were fabricated from flat bar.
Any other updates on this? Did Lextreme ever end up making and selling any poly mounts? I tore a driver side mount on the chumpcar racing SC400 I have. I'm debating just welding up my own solid mount, but don't know the angle between the studs.
