Our 1984 Toyota Mirage
SEEN HERE was built on a 1983 Toyota C&C chassis. I believe your 1984 chassis has the same 2.4L engine, but with multi-port fuel injection which is so much better. Not just 19 more horse power compared to our California emissions carbureted engine, but today's fuel with 10% ethanol was so hard on a cold start diaphragm on the side of the carb. I had to replace it every-other year due it getting stiff and ineffective. It was dang hard to get and later very expensive to purchase.
It looks like your rig also has the updated rear axle with true duel rear wheels. You are all set with that.
Our little Toyota had a stick shift 4-speed and it was great. We bought it brand new in the fall of 1983 and sold it 23 years later with 107K miles for $4625 less than we paid brand new. It was one of our best investments in life.
We drove a slow and steady 57 mph on the open road, let everyone pass us by, and it served us well. Our trip average fuel economy was often just over 20 mpg, but that rig weight only 3500 pounds plus what we added into it.
