Definately a 16 valve motor.
It has 1.6 Liter, 16-valve, 4-cylinder, SOHC engine with Multi-Port Fuel Injection. 95 HP |removethispart|@ 5600 rpm and 98 lb.-ft. |removethispart|@ 4000 rpm.
When rounding up parts for your conversion keep in mind that '96 and up motors are OBDII and will not be smog legal for California. On '96 and up donor vehicles you will need to get the second 02 sensor portion of the wiring harness in addition to the parts listed below.
You will need the engine complete with all of the hoses, pulleys intact. You will need the fan, starter, alternator, coil, air cleaner, exhaust manifold, head pipe, engine room wiring harness, under dash wiring harness, ECM, and speedometer.
In addition to this donor parts list you will also need a high pressure fuel pump, an engine adaptor kit, and slightly taller mounts or shims for the front 4 body mounts in order to provide for hood clearance. The donor vehicles wiring harness will need to be modified for use in the Samurai as well as the Samurai speedometer which will need the speed sensor from the donor vehicle adapted to it.
In my opinion Trail Tough is your best bet when doing a 16v engine swap. They also have a special going on and the conversion kit is currently 40% off the original price
