Hello. I have a question and any info would be appreciated. I have an Australian made 2001 Camry XV 20 4th Gen, with 5SFE which is rated at 94kW. I also have a ECU from Japanese made 97 ST204 6th Gen Celica, which also had a 5SFE but it is rated at 101kW. My question is what are the chances that I will harm the engine if I connect Celica's ECU to the Camry. Thank you.

i have swapped ECUs from plant engine but i would touch a car ecu from another country, also some ECUs are linked via vin/chasiss number. if you swap one from another vehicle the whole system shuts down.

His car is a little to old for that :)

it may work, compare the pinouts to be sure... that said the 2ZZ ecu between the ZZE corolla and ZZT celica are wired differently.

also, that extra power could also come from different cams, different injectors, different ign system, etc, etc

Good luck but doubt it will work, there are many differing factors, such as pinouts, sensors and possibly even connector sizes. Could it be made to work, possibly, but I very much doubt it will be plug and play.
