I dont own a honda but with all this discussion I am probably going to keep my eye out for a vx...
Can lean burn be acheived with the vx ecu/sensors and the next size engine retained such as the 1.6? Personally if that is possible i would be totally happy with, say an 89 hatch dohc with lean burn enabled.
Everyime I look for a JDM mazda motor the big companies are in Jersey, or Canada. You can probably buy one will-call cash and take it home in the back of your car! I have to pay pay pay shipping 3,000 miles.
