2010-13 Mazdaspeed 3 Engine and Performance
I bought a 2010 speed 3 recently. Got it for a great price, but it was too good to be true. The engine had severe knock and unfortunately it seized up. I’m thinking about doing a swap. But not sure which engine. I’d like everyone’s options on this, Stock engine 2.3? Or could I do a 2.5 fusion...
