school me on 4 door 70s

I thought, perhaps incorrectly, that the 2L-T was actually a fairly reliable power plant and only had issues when the letter “E” was added.

That's what I hear too. The 2L-TE is the one with the issues. The 2L-T and the "2L-T II" (2) apparently are less prone to issues because they are less torque-y than the 2L-TE, according to this site:

Toyota 2L-TE – Engine Specs

The "E" in "2L-TE" signifying Electronic Fuel Injection...

Wow, this is an old thread, The data on this notion is a bit sketchy from what I can tell. The LJ with 2LT (early years of the box prado) are known to crack cylinder heads at a certain point due to indirect injection and/or being slightly underpowered, many have been replaced under warranty or previous ownership. The 1KZ-TE is the successor to this engine, the KZJ7X I believe 1995 and 1996 were fitted with the 1KZ and its a great engine! pulls well, pretty quick (for a cruiser) and efficient. These models have only recently been able to be legally imported into the US. People say to avoid these 1KZ models like the 2LT, but I haven't heard much of this from people with actual first hand experience with the 1KZ motor, pretty much always hearsay. I personally believe the reputation of the early LJ7X followed the Box style Prado until the body refresh in late 1996 to the next generation Prado, kZJ90 where the 1KZ-TE engine continued to be used until I believe the mid 2000's, Toyota had however added an intercooler to the newer model Prados. I don't think if the 1KZ was that bad of an engine Toyota would continue to use it for another decade. I threw caution to the wind and bought a 96 KZJ78 with 200k+ KM on it and it runs amazing, love it. Time will tell what issues the 1KZ-TE engine develop for me with more use. I am guessing it will be similar to other owners of 25+ year old 70 series and I'm ok with that.

I also saw in some markets they put the 22re in the early 78 prados and the 3rz in the late 78 prados. I think if my 1kzte ever blows up or starts giving lots of issues I may think about figuring out a 3rz swap. I had a 3rzfe in my 1st gen tacoma and it was awesome! I literally drove that tacoma till the frame rusted in half. patched it the frame then the lower ball joint failure killed it. it had almost 400,000 miles and the engine still ran without burning oil. I think that big land cruiser museum has one with the 22r in it. Land Cruiser Heritage Museum - 1992 RJ77 - https://landcruiserhm.com/museum-collection/vehicle-collection/167-1992-rj77 Its a rj77 other than the 22re engine Idk what the difference is. maybe axle ratios. This being said I have not had any issues with my 1kzte.
