hello all. I need some help here if possible.
My sister bought an 02 civic ex but the stock d17a2 had been pulled out becuase it was blown. So i went online and got her a jdm d17a with matching 5 speed trans.
the new motor and trans came complete with harness and all the accessories.

My question is this- what will we need to swap over in order to make it work in her USDM civic? i've heard the intake manifold sensors need to be swapped and a crank position sensor needs to be installed, but i cant find much info on it. i've also heard others say that it'll drop in and plug right up with no problems. any help would be greatly appreciated as she needs to get the car on the road asap.
