New guy looking for Toyota Pickup Forum

I'm looking for a forum on early Toyota Pickups (79-89) what are they classified under? Also, I'd like to know what the engine interchanges are? ( ex:can you put fuel injection on a earlier 20r-- is it worth it).

I have 2-- 1/2 ton pickups

I have a line on a 87 2wd ex-cab I'd like to build into a low rider.

Anyone with info on nitrous or superchaging a 22RE--can their bottom ends take it?

Any info is appreciated, thanks in advance!!
