their is a rwd conversion for the 4g63.. it is kinda expensive. even if u bought a cyclone swap it would end up costing a grip of money..
i may be bias towards a import.. but to do a drop in motor swap you should have about 10grand set aside.
motor tranny
new seals(full)
new fluids
possibly new rings
clutch/flywheel why u are their
timing chain/belt
and thats before you start modding the motor at all. these jdm import engines have been sitting a long time. even if you get a usa motor its still being pulled from a early 90 motor...than u could be talking an evo motor but thats a grip of cash up front.
u are really better off keeping the yellow car and doing bolt ons, full heads, ect ect.. suspension.
