terrible vibration 3500rpm and up
recently i bought a 1988 RX7 convertible. Great car. Buddy borrowed it and blew the motor, a 13b. I changed it out with another 13b and now at around 3500rpm, the engine begins to shake. It does this regardless if the clutch is in gear or if I am driving down the road. I am not a gear head and it seems that all the mechanics around here think a rotary means the pistons turn sideways. Any help?

Anyways, onto your problem. Possibly either a motor mount problem, or a balancing issue. You say it does it even with the clutch in? I would say something is out of balance - when you changed the engine, did you screw with the counter weights, or did the flywheel get damaged in anyway?
