Hi all unfortunately for me I have a 1990 miata with a bad crank and have tried the repairs without any lomg term sucess. I am now going to find a newer engine. Does anyone know if a 323 1.6litre is the same or should I be looking for a actual used miata engine. thanks all!!

 

If I was you, I would drop the 1.8L in there. But the 323 motor would be less HP anf torque.

 

i say just do the 302 small block swap. that will give you a thrill

 

good luck shoe-horning that into that little engine bay...

altho i have seen a corvette engine swapped into a pontiac solstice...

 

Monster Miata has a 302V8 kit. It's being built on the ESPN2 show Gearz.

I think it would be totally worth it.
