Ok well the only mod i currently have that shoudl cause vibrations is my tranny brace. Now i had that before i blew up my tranny at it only caused a slight vibration at 3,500 rpm. Now i still have that but now with the leight weight fly wheel and counter weight and new used tranny i get some vibrations from 6k up. I was just wondering if this coul dbe because of the new fly wheel now paired with the tranny brace or if this is a serious problem. It's very slight vibration and the engine doesnt make any sounds that it shouldent. could this be something i shoudl look into. And yes every thing is tight and lock tighted, i double checked it all myself. Thanks for any feedback.

 

Pressure plate? Bad Pilot bearing allowing vibration? You said you had alittle vibration before, otherwise I might consider the transmission input or output shafts being sloppy. Your drive shaft needing balancing. Bad U joints. Just throwing things out, I dunno.

 

does it vibrate in neutral? if not its prob the u joints

 

yeah i'd look at the driveshaft, its possible its out of balance

 

The tranny brace will cause vibrations. Try removing it and see if it goes away first.

 

no vibrations in neutral, it's not the throw out bearing i'm sure of it it made noise at fist but once it lubed up it stoped, ah lot's of people keep telling me the drive shaft, how do i check it?

 

Removing the tranny brace sounds like an easy first step in the diagnosis. If that isn't it, are you sure you used the right counterweight (i.e. it has to be the right one to match your rotors and front counterweight)?

I'm pretty usre there is only one counter weight, and it comes off the auto 7. Plus i bought the counter weight off a RX-7 mech so i dont think he was goin to sell me the wrong part.
