i just got done having a b16 put into my ek hatch....when I go on the highway sometimes on high speed or when I down shiftm it seems like the driver side axle is grinding or the suspension is not acting right....I'm using a 99-00 si axle and motor.

 

put it up on jackstands and run it....make sure it is secure. and get down and look at what is going on. you will need two people to do this of course.
