Hey I did my swap like couple months ago put a b series in it. Well the thing is that I get a lot of vibration around the 1500 to 2500 rpm range after that it's pretty much smooth. I had avid mounts on first n thought that was the reason so i put stock one in and it still vibrate, then thought it was my exhaust so I took it to the exhaust shop to look at and they say that wasn't it so now I don't really know what's causing the vibration, motor clears the hood it doesn't touch anything. You guys think it might be my tranny or something? Ur help is very much appreciated. Thanks in advance.

 

gsr's had a tsb on the exhaust manifold b pipe for vibration at that RPM. look into it.

 

think i might need a flexy?

 

worn axles will also do this. i did my ls swap in my hatch, and had the same problem. i figured out what it was when i broke an axle @ the track. i replaced it and had no more vibration.

 

i have the same problem. my pass. side axle boot has a tear in it. i gotta go pick one up and put it on. but my friend said its the axles.

 

both axle are new

 

try an aftermarket crossmember. darkstarracing.com has a bad *** one that stops shakes and wheel hop

new or remanufactured? that still doesnt mean that they are not out of balance, or worn on the ends.

 

they're remanufactured but i jux got them like 2 months ago, I really don't think its da axles because the vib. is the there even when the car is not rolling, on cold idle. I really think its something other den that.
