Just wondering if anyone else has had a noticeable increase in vibration after doing a swap. I have a 93 EJ coupe, with a B20 with jdm b16 lsd trans. The motor, tranny, clutch assy are all stock. There is a noticeable ibcrease in vibration, esepecially when cold. At first I thought it was the missing front transmission mount, but I have since replaced this part. There is also a missing a/c bracket to frame mount, but could this mount really cause that much vibration? Also it seems to level out around 2000-2700 rpm, anywhere else in the entire RPM band, it's there. It's also quite a bit worse when cold. This is not totally unbearable, but it is rather annoying. Any help is appreciated.

My advice would be, first, get the bracket you are missing.
Then find a service manual. There is a certain order that you are supposed to follow when torquing down the motor mount bolts, to help decrease vibration.
