So this may seem like a silly question, but does anyone know the specific differences between the two motors? Is it just a intake manifold and a ecu tune, or is it a completely different animal all together? I used to have a rsx and the main difference between the base and type S (engine wise) was the IM and some other little bits you could buy and swap. Thanks!

Two different beasts.

There is a wealth of information out there and though this forum is full of people willing to help, I doubt you'll find the person willing to recompile and retype that amount of information. With a bit of research into your new hobby, I'm sure you'll find everything you're looking for. Plus, your memory will then be far fresher than most here.

If you're interested, there may be those willing to provide you with some links or downloads to both help and inspire your investigation. Good luck.

Great question. This video has the answers you are looking for.

They are completely different. As far as I know, only the oil filler cap, cam and crank sprockets, and the crankshaft reluctor wheel are interchangeable between them.

The 2ZZ-GE was designed based on the 1ZZ-FE, but that is more of a "same displacement, number of cylinders, number of valves, DOHC, and has the intake/exhaust/flywheel on the same side" meaning than "basically the same engine, just tweaked a little."

I also have a pdf on the development of the 2ZZ many may find interesting. Let me know if anyone wants it. I've offered it up before. I may even still have it in my Drive for sharing.
