Only way to rectify would be to check the mountings and later on get an engine damper unit

But i have just changed to new sets of mountings, a harder type than the stock and it's worst than before, i can feel the whole dashboard vibrationg and giving all type of anoying sound. i'm using sr20ve on my B14.......will racing mounting cause this problem???...but it was already vibrating like hell before i installed the racing mounting it self??? The vibration is bad at idle and is the worst when the car is just about to move ( when i release my clutch)....there is no problems at high revs.....pls advice........

hehehe , its race mountings are like that , cos its stiff it doesnt absorb like normal rubber.

but is ur car performing well , if engine not performing then it could be engine problem

ok when u sit in ur car n u rev let say to 1.5krpm , does it vibrate more ? i mean on idle

its for race use, of course not suitable for daily use. same like people who use race camshafts and complain that engine wont idle with aircon on. want power+comfort, go buy an M5.

best solution, change back to standard mounting.

If its the mountings, you should really feel it during high revs. I had transplant & mountings were not done properly. Vibrate like hell when hard accelerating cos engine touch chasis.

its racing mounting. designed to hold the engine stable at high launching, high revs, high speed. but sacrifice lower rpm comfort.

As I know, SR would bring a lot of vibration compares to RB. As Khoyos said, if racing mounting, sure have this problem as normal drive. In this case, drag a lot my friend, then no more vibrate! =)
