OK, Fuel Injection started in 1985.
We are talking about 22R motors here. The 22R is a 2.4 liter 4 cylinder. Its a nice motor, a workhorse like a 258. Just want to keep gearing correct for bigger tires and keep the weight from getting crazy.
When it became fuel injected, its then called the 22RE
Not ALL 85+ are fuel injected. The 2 bbl 22R was available until 1987. So, 1985 is the sought after year, you can find a solid axle and fuel injection.
My truck is a 1985 with the solid axle and fuel injected motor. Well, I'm only using the body of it, the frame is an 83 and I'm running an 83 motor with a Weber carb, but the fuel injection is going on soon....
There were limited 86-87 models with a fuel injected turbo 22RET, and after that there were the 3.0 V6s, which most people would rather have a 22R. The V6 has a reputation for eating head gaskets, and will hydrolock with oil on a flop onto the passenger side.
I don't know much about land cruisers, except they are expensive...
