I'm new to this forum and the Mazda 2.3 engine. Could someone please tell me differences between the MZSPD3 2.3 engine and the N/A 2.3. I want to build up an engine for high boost so if there is nothing different between the two other than pistons, rods, and cam driven fuel pump then ill just get the N/A 2.3. Any info would be great. Thanks!
