Can I put a v6 moter in my 1.6 leter mazda mx3
Yes you can. Will be easy if your mazda did make a v6 that year. You can pretty much put whatever motor you want but just know it will be alot of work and probably some costom fabrication.
Substituting a V-6 is not practical, so the answer is.... No, not easily.
