the car in question is my girl's B20vtec/GSR swapped EK hatch. Its got a really pronounced vibration on acceleration only, the harder you accelerate the worse the vibration. Coasting and decel are fine, no issues. I got the car from a buddy of mine who did the swap, he said it's always been like that ever since the swap. Is this most likely to be an axle/midshaft or motor mount problem?
