Ive got a glanza engine out of a 1996 car i know the 98 spec cars are slightly different so how hard would it be to fit the 96 spec engine into the 98 spec car?
You may just need to change over a few sensors to get the loom to suit, everything else should be a straight swap. Compare the 2 engines when you get the 96 out and swap over the sensors that have different plugs.
