Hi. I had a nitrous kit put into my 2003 protege5. The shop installed it incorrectly and repaired my engine supposedly but when I got it back it still didn't run. I tore the engine apart and the idiot left big chunks of metal in my engine and the oil was like sludge. I need to replace the engine and was wondering if I could possibly put the mazdaspeed engine in my car.

 

no Mazdaspeed engines are available...Mazda is very particular about getting the parts...you can get a 2.0L and turbo and have more power than a mazdaspeed anyway...the real differences are in the tranny and suspension

 

a promazda member bought a mazdaspeed motor off ebay...check there.
