There can be many varieties of answers to this question, so I want to see what kind of information or even theories you guys can sum up. A GSR swap is about to happen soon in an EG and I was wondering... - How can a 1994 GSR motor (13-14 years old) have such low km's, or so the suppliers say? Hypothetically, assuming that most reputable motor swap dealers are truthful, how and why are these Japanese motors of all sorts have such low km's? - I originally wanted to get the ODBII GSR because theyâ€™re 96-2001, so I guess theyâ€™re more new motors; but I am reluctant to get them because my car is ODBI, and wiring would be difficult. So let me ask you guys, would the cost benefit principal say that I would be better off with the simplicity of the ODBI motor which may suffer in reliability solely because of its old age, or more beneficial to pitch in a few hundred dollars for the ODBII-ODBI conversion harness so I get a newer motor? With the conversion harness, is the swap literally a drop in and plug in? - Or am I being paranoid and underestimating the reliability and durability of Honda motors?
