the protege 1.8 and miata 1.8 i believe are about the same. i dont think there are identical though on the outside of the engine. internals i think are the same. check this link out and you'll see evrything you need to know http://members.aol.com/solomiata/MX5Engine.html
thxs for the info
Since im a complete newb i may aswell get a few things straight.... honestly i don't really know what a mp3 or an mp5 is, i just assumed that an mp3 was a pretege...?? And my car (protege) is a 1.8L. They only started bringing out the 2L versions of 323 in Australia last year i think.
Performance parts for my car aren't that common here so the mx-5 idea was just stupid. =\
MP5= Mazda Protege 5 MP3= A performance version of the Protege that came with an MP3 player from the factory. Mazda quit making them in '01...or maybe '00? MSP=MazdaSpeed Protege. Basically an updated MP3 with a turbo.
...All 3rd gen Proteges.
