today i spent 2 hrs fitting my new poly engine mounts,
if there is anyone out there still running on standard engine mounts, change them the bushes cost me 50quid and 2hrs very easy work they make so much difference, really gives a punch on when hard revving as you can tell i am as pleased as punch really transformed my mr poo into an mr2 lol

Not sure but if you hear a bang like a gunshot &p and then you hear a slight knock when you are on/off the throttle:/

Re: poly engine mounts!!
It's not uncommon to have that bolt ripped out of the gearbox. Best thing to do is either drill & helicoil if available or just drill & tap out to next size up & use a new bolt. (Will have to open up the hole in th mount iirc)

Re: poly engine mounts!!
What are the poly mounts like for NVH? I always heard that you stay away from them on a roadcar unless you like the whole thing vibrating on idle.
I noticed that fensport still have the TRD gearbox mounts available, assuming that their like the trd topmounts being a bit stiffer?

Re: poly engine mounts!!
I mean yea the car does vibrate a bit at idle but...nm. I had poly inserts on my corolla t that also vibrated and it makes the engine sound louder IMO.
Liveable though.

Re: poly engine mounts!!
Don't bother with Helicoils - waste of time.
TimeSerts are what you need.
IMHO, uprated east-west mountings are pointless. They have no effect on the rotation of the engine due to torque.

Re: poly engine mounts!!
Just my experience but I had my gearbox mount helicoiled nearly nine years ago and I've never had a recurrence of the bolt working loose
Agree on the east-west comment too. I bought a set of TRD mounts, changed the front / back mounts and sold the east-west mounts for nearly the same money as the full set! Definitely more vibration but far less movement. Gear change slicker too due to the decreased movement under load.

Re: poly engine mounts!!
where do you get them?
This is just the front and rear lower mounts? There aren't any others? I've not looked into it. They don't need changing?
I found powerflex ones on eBay for front and rear lower engine mounts.
