hi everyone. i have a ek hatch just finished the swap to B18cr. the car was smooth before the engine conversion. but after swap the car feel shaking when accelerating. i have a 96 spec B18cr and gearbox. 96 spec hubs. and i have tried both dc2 and ek4 drive shaft and center shaft. the problem still there. its shaking anytime when step on the gas. especially from 20km/h to 60km/h. i have done the wheel aligment and wheel balance, swap the wheel from back to front but no luck. any idea please?

 

loose outer tie rods IE: nut not tightened to the spindle?

 

I have the same set up except 98 b18cr.
Check out the engine mounts especially the rear mount.
If not this then check to make sure there is no play in all three shafts.
but it does sound like mounts.
hope this helps
