I was on here a couple days ago and in a thread someone posted the link for all of the mazda 323/pro/3 engine specs. I can't find it now and I found an MP3 for sale that has had a JDM engine swap done. I want to do some research about the motor. Also if anyone has details they can post those too, but I'm really looking for that link, thank you.

 

the JDM engine that swaps into the mp3 is called an FS-ZE. they barely make any improvement over the stock US spec motor if they are using the stock computer (more than likely they are as swapping to a JDM computer requires an entirely different wiring harness and makes the car emissions illegal). the JDM engine is also a high compression engine which may not run right or even blow if using the stock US computer. you would need standalone engine management to get any measure of power out of this engine. the engine compression ratio is 10.7 to 1 versus the american 9.1 to 1.

 

Should be in "The Bible".
