Let's make this a one-stop thread for these numbers. Why do we need this? Because while Toyota offers these pistons in at least five different diameters, most websites (and some dealerships) will tell you this, regardless of what P/N you give them: "Piston, w/Pin." Which is absolutely useless. It's like Toyota is TRYING to be obtuse. So, down the borehole we go...
Standard pistons come in three diameters, to accommodate slight variations in bore size. You'll find a number on the top of each, indicating whether it's a Mark 1, 2, or 3...
Piston (Mark 1) w/Pin. 13101-66040-1 (precise dimensions below)
Piston (Mark 2) w/Pin. 13101-66040-2 (precise dimensions below)
Piston (Mark 3) w/Pin. 13101-66040-3 (precise dimensions below)
Standard Size Piston Ring Set. 13011-66021
(Fits Mark 1, 2, and 3 I believe. Can anyone confirm? Thanks!)
Piston w/Pin (0.50 oversize) 13103-66040 (maximum dimensions above)
Piston Ring Set (0.50 oversize) 13013-66021
Piston w/Pin (1.0 oversize) 13105-66040 (maximum dimensions above)
Piston Ring Set (1.0 oversize) 13013-66021
Oversize P/Ns triple-confirmed.
