Hello all, I'm new here!

I might buy a 1990 Mazda 323 tomorow. The engine is a stock 1.6L 4-cyl with a 4 speed automatic transmission. Since these cars seem to be pretty light, a motor swap would work good I think right?

What would be an easy swap for this car?

I've heard that the 1.8L SOHC from a Protege between 90 and 94 would be the easisest and cheapest way to bolt-on some performance. Is it true?

With this swap, do you think I have to change the wiring too and other stuff? Or just the engine and computer would do the trick?

Would I get more performance by switching my automatic transmission for another one from an Escort GT or Protege LX/GT?

I know I could buy a turbo motor from some 323 and V6 from MX3, but it would cost too much for me so I'm looking for an economical way of having a little more power.

I may only do a good tune up too, what you guys recommend for spark plug brand and model for Mazda vehicules? I know GM is ACDelco, my Plymouth Champion... But what do you guys recommend for Mazda in these years? For the other tune up parts, do I use Mazda brand or something else or anything?

Thanks in advance!

See ya!

 

Welcome to the forum!

When it comes to plugs, either go with NGK or ND (Nippondenso). These are made for this car. ACDelco is great in a GM as well as Motorcraft for a Ford. It is best to stick with stock in my opinion. Just go with a good tune up with plugs, cap, rotor, wires, fuel and air filter and see how it runs. Make sure the tires are also good and properly infated. At the price of gas these days, get the most bang for a little buck! One downside of performance mods and driving harder, less MPG.
