Polyeurethane mount vibration

[inthemidst]

I have. A 96 gst 6 bolt swap balance shaft eliminated and polyurethane mounts all 3 and front mount only has inserts . My steering wheel vibrates like hell when I rev past 1500 rpm it fades away.just want to know if anyone thinks this is normal car idles perfect no misfires or check engine light.

This is normal with aftermarket mounts and balance shaft delete that how my car feels it vibrates a lot

How I like to describe my car to other people: if the rearview mirror isn't shaking to the point you can't see out of it, turn the car on.

If you do this to your inserts should help with the vibration. There is a writeup about it but I can't seem to find a working link to it. A lot of my bookmarks no longer work since the site was changed.

What kit or method did you use to do your BSE?
Also did you have your rotating assembly balanced?
I did a BSE using STM kit and had my rotating assembly balanced and it feels just like stock. No vibrations etc.
I still have stock motor mounts though. If I switch to the inserts I will drill them out like in the post.

Exactly. How it stays tight enough not to move out of position ever is beyond me.

Normal. Put some polyurethane sub frame mounts in too. If your keys aren't vibrating your not doing it right

I got my keys to stop shaking at idle with ac on but I'm pulling 33 percent fuel my short term fuel trims show add 17 percent do you guys know if I can get some melted pistons or valves from running so lean at idle. My o2 sensor voltage reads .060 not .60????

I want to advance my intake cam one tooth on my timing belt to give me faster acceleration and more low end power my question is are their any cons to doing this?

Get your tune down first before adjusting cams. What you want to do is not just mess with advancing a tooth, I'll put a YouTube video for your cam question. As far as the mounts, if you can see out of your mirrors with poly mounts then something is wrong. I can barely use my side mirrors. I don't even bother with my rear view mirror

Is that a joke? You dont skip teeth on the timing belt, you do it right eith adjustable cam gears and a degree wheel.
