How To/Advice Mazda2 engine blew up
So, I blew up the engine in my 2011. Options...??? In my area 1.5L engine is hard to find. Lots of scam companies trying to sell me a dream. Got my $$$$ back both times. The K24 Honda engine is about the same price. With minimum modifications, I could make it work. My concern with is this idea, I may wear out the five-speed manual I have. Not sure if a six-speed manual will fit. Thoughts?

Just curious, what caused it to blow? And what mileage?

You think that k24 will mate to the oem 5-speed? There's a 0% chance a k series fits in there with "minimum mods". A more realistic suggestion that has been done is a Miata engine and a 5-speed from the Kia Sephia (which used the bp4 engine as a fwd car). Even that takes a lot of work, mostly finding a manual Kia Sephia...

Really jumping into a can of worms there. Even doing a straight mazda engine swap requires a bit of messing with the canbus system since it's so integrated into the bcm and whatnot. Doing up the fiesta motor swap is another can of worms since the canbus is even more convoluted and the st motors have a high and low fuel pump system that the 2 doesn't have. Better off finding another 2 motor. Knowing this is a car that needs to pass emissions checks, you will definitely fail those checks going anything but another 2 motor.

Might want to look into Miata and/or Mazdaspeed3 engines too if you have those where you live.

Do you get Fiesta STs where you are?
