Honda Engines Swap

Recently swapping engines such as Honda and Nissan for the JDM models has become very popular. This is partly due to the great quality of the JDM engines, but also the fact that many engine models are only available in Japan as a part of the JDM range.

Swapping an engine can be a tricky job though, so it is recomended that you get a mechanic to do it. If you choose to do an engine swap yourself (especially a Honda engines swap, given the large amount of wires and bits and pieces) make sure you get an engineers certificate if it is not the original make of engine.

Below is some important information on doing a Honda or Nissan Engines swap:

Emissions and Legal Issues

In most (if not all) cases, Honda Hybrids remain emissions legal, thanks to the low emissions levels of Honda engines. However to stay emissions legal, you will have to retain all the emissions hardware that came with the original chassis/engine or, even better, uprade the emissions hardware to the one that comes with the new motor.

The essential hardware that is required for legal emissions are:

* catalytic converter of the correct type
* properly functioning O2 sensor
* properly function evaporative emissions hardware

Due to the different emissions testing standards in various states, a hybrid may not pass certain emissions requirements. For example, California vehicles have to pass a visual inspection in addition to the emissions tests.

Staying legal is not difficult too. Most states require that engines can only be replaced by engines of the same or later model-year vehicles. Hence, it is easier to find replacement engines for older cars than for newer cars. Some states keep a record of the engine serial numbers so make sure you update your vehicle registration with the new serial number.

One last thing. Make sure the engine has proper paperwork when you purchase it. Serial numbers are required to be on the engine, so that it is easily traceable. With the prices of certain engines skyrocketing due to the large demand, there is always a market for illegally acquired engines. I know of at least one HP list member who had his hybrid Prelude engine confiscated as it did not have a serial number.
