I have a 90 hatch with d15, 4spd and Non MPFI, I am looking in to Swaping the motor For either a B16 or B18. I was wondering which swap is gonna be easiest overall, wiring, mounts, etc. I have a shop with a hoist and lots of tools, welder etc. Would buying the engine tranny combo form JDM source or others be the best bet? and would i need any other Parts to complete the swap?
