Hi Mohan, the Kia Spectra uses the mazda B series engine. Im not entirely familiar with the configuration but back in the days a number of em converted these to the B6T or even the B8T or B8Na. assuming your goal is not to be making tons of power but to be comfortable for daily use, you may want to look into the B8Na. Having driven a ford lazer that comes equiped with that engine, i can say it was a very comfortable engine to have for daily use. nice amount of low end torque. Do note, these engines are old, i dont even know if theres any still available around. your best best is to look around the fb pages for the mazda ford boys. i just did a quick search on fb and saw a guy sold of the B8 Na engine, gearbox, ecu n wiring for RM2800. All the best.
