Re: BAD VIBRATIONS.....
I had the same vibration issue with a ef hatch i bought with a b16 already swapped. My first hunch was the crossmember because it hadn't been notched. Well I notched it and it didn't fix it.
The problem was the axle / intermediate shaft setup that the prior owner used. He had a SIR halfshaft (from ef hatch or crx) and was running Integra axles. For the passenger side that's fine but the driver side needs to be a hybrid of two different axles which is an 86-89 integra axle with the 90-93 integra inner joint.
You need to figure out which halfshaft you've got to determine which axle set-up is correct.
Go here for a better explanation.

Re: BAD VIBRATIONS.....
-yes it does it when i drive
-i have been told by several people that it could be the mounts but i didnt think that it would vibrate that much
-i am using 90-93 integra halfshaft and 90-93 integra axles

Re: BAD VIBRATIONS.....
Solid urethane mounts are pretty harsh. Take a stock engine on it's mounts, and shake it back and forth. Then do that with the Hasport mounts. Big difference. It's also the reason that GSRs came with liquid filled mounts, and the reason that most stock mounts are a series of rubber webs instead of a solid puck.
Solid mounts are nice for shifting and drag launches though (if you can stand the vibration) so take it like a man. EFs are prone to stuff like that because the chassis is pretty flexible and doesn't have enough stiffness to keep that isolated to the front end. Blame 80s engineering and manufacturing.
Don't ever cut anything around the engine mounts if there isn't a clearance problem, there really isn't any reason to weaken something unnecessarily just to help vibration. That's ghetto as hell.
