I have a b16 with hasport mounts and it makes a lot of vibrations and rattling in the car between 2000 and 4000 rpm. someone told me they had to break in and the noise would stop after about six months. I don't know about that. My thought is that it no longer uses the front mount. Is this normal or is there something I can do to prevent the vibrations.

 

Well it depends on how bad it is. Mine vibrated a lot at first also. I really thought the installation was wrong, but I asked the shop and they said it was normal. It went away after a few months. The mounts give a little after a while and the vibration should reduce. Just make sure you check the nut's and bolts because mine started coming loose from the vibration after 2 weeks. I had to take it to the shop and get them to tightened them again. They said that 1 bolt had come loose. That 1 bolt was night and day from the vibration.
Enjoy the B16, I know I do.

 

yes its normal. I have Place Racing mounts for my B16 in my CRX. That thing rattles like a biatch! You'll get used to it though. People will think that your car has some ***** with all of that vibration.
