240SX came with 2 different lug patterns. All 1989 to 1994 240sx came with a 4 lug 4x114.3 pattern. While the 1995-1998 240sx SE/LE's came with a 5 lug 5x114.3 pattern. Preferrably you'd want to find a wheel with less than +30 offset for 240SX's.
I believe for yours it is 5x114.3. As for the 1989-1996 240sx is a 15x6 wheel with 4x114.3 or as for the 1995-1696 240sx se is a 16x5.5 wheel with a 5x114.3. Reference: http://www.discountedwheelwarehouse.com/Nissan___Vehicle_Bolt_Pattern_Reference.cfm
No speed sensor on the manual trans. The speedometer signal comes from the rear axle speed sensor.
back center of the block right above the oil pan it has 2 wires going to the one above it with one wire is the knock sensor
if it is the 4 lug its a 4x114.3..... if it has been converted to 5 lug= 5x114.3
