Hello you wealth of knowledge on CFF. I am considering either buying a newer 6 cylinder pickup or just changing the engine out of the existing Tacoma from a 4 cylinder to a 6, if that is even possible. It is a 1994 Toyota Tacoma extended cab with 210K miles. The body is in great shape, no rust, four wheel drive, stick shift 5 speed. I have a trailer and it is all this little truck can do to pull it. Does anyone know if changing the engine is cost efficient or even possible?
