Bad vibration!!

Have you had any noticable difference in pedal feel? Does it happen whether or not the clutch is engaged or disengaged? In other words, if you have the car in gear and clutch pedal down (disengaged clutch) does it still vibrate? If so then it is probably not the disc, since the disc is not spinning at that time. You also said "loud noise" which makes me think release bearing problem, but generally vibration doesn't accompany a release bearing problem. Does it feel rough like a bad bearing or does it shake like a balance problem? I hope you figure it out!

It does it everytime my car hit about 3k rpms and over, if im not moving or if I am, If the clutch is in or out.
OUCH!
wouldn't you think it would take out the pistons first, before the crank? i mean these cranks can handle 800whp!!!
if you need any parts, i have a complete bottom end.
for me, i bought the crashed evo with a cracked block. the crack went from one end of the cylinder to the other. had to rebuild mine as well.

I know this is a long time ago but I might have the same issue. I delete balance shaft and install a harmonic damper and still the vibration.
my second choice is change flywheel and clutch to see if it goes away. And now I read this post and Im crying right now🤣😭🤣😭🤦♂️
