They're the Ford Laser/Mazda 323 specialists.
What you got there is esentially a Mazda 323, the FS-ZE 2.0L is a direct swap, the 1.8L gearbox and clutch mate up with no modifications, the factory
ECU will also run the engine no problem except being a little rich.
You'll run into an issue though because the 1.8L
ECU will only let the thing rev out to 6400 RPM before cutting out, the FS-ZE peak power is at 7200 RPM, but its still a ******** better than the 1.8L.
You'll need to import the engine from Japan or NZ as that engine wasn't an option in our cars (SP20 had a weaker 2.0L engine, different model. only 90 something KW).
