We took a 2.0 out of a Suzuki Aerio and installed it in Drone637's Race car. A little more involved, switching oil pumps and pans, making new drivers side motor mount, turning exhaust pipe out of Cat, changing flywheel, etc. The Aerio has more Hp than the Tracker/Vitara, it fits in and looks good. If you want to stay with manual transmission, get a motor & COMPUTERS that had a manual, otherwise you may be running with a CEL communication failure. The Tracker/Vitara/GV 2.0 swap is easier, but blending the computers from one to the other takes time and patience. The motor swap is almost a drop in.
Also installed an '05 2.7 with 5 speed automatic from an XL7 in my 93 2 door. Tight squeeze. I also went with a dual exhaust.
