Ok welltoday I started experiencing some vibrations in the car above 5k rpm.
Basically, the car feels normal up untill then, then it seems the motor gets abit louder and I can feel a vibration in pedals.
It doesn't seem to have lost any power.
The motor is a B18C in an EL.
Could it be a mount or an axle?
It doesn't matter what gear it is, its always the same vibration.
If I let off say at 7k rpm, the engine gets louder as it revs down and then starts to fade around 5k rpm.
I have noticed the motor gets louder around then.
Last night I missed a gear and revved the motor to about 9k (mugen chip) it was the second time I've done it...

The vibration might be caused from the mounts, the noise im unsure. When you did the swap what mounts did you use?

Dominik

The swap was done with type-r mounts.
It just started. I suspect a fouled spark plug or maybe the coil.
It just sounds as if it were on 3 cylinders, but I don't feel the power difference...
I'm going to check the timing marks... or just take it to pro-spec tomorrow.

i have the same problem ,
my vibration is different , sounds like something is loose and just spinning around rattling, at first it soudned like my dash was rattling but it was comming frmo somewhere else


i'm going to get it checked out soon, if u find what yours was let me know so i can let the mechanic know of someof the possible problems

Dominik

It was my timing belt mount.
Check yours asap. The mount rubbed away 85% of my timing belt.
