I have swapped engines and transmissions and am running into some questions for someone that has done it. Please let me know if you have.

After careful examination of the cars wiring and also the connections to both 4A-FE and 7A-FE ECM/ECU's, I have come to the conclusion that I need to abandon the project.
Althought it is physically and mechanically possible to swap a 1.6L 4A-FE engine and A131L transmission with a 1.8 L 7A-FE engine and A245E transmission, it is electrically unfeasible (within my capabilities) to convert. My next step I believe will be to locate a working 1.6L 4A-FE engine and purchase it for replacing the 7A-FE engine that I have installed in the car. I will re-use the old transmission (which is still good) and also the old wiring harness and ECM/ECU (will match up with no complications). Thank you all for the helpful advice and encouragements. Unfortunately the operation was a failure and my only recourse is to return it (as much as possible) to stock condition. At this point my son will settle for any operating vehicle and this decision seems to lead to that desired outcome. |
