Found a great replacement motor for the SCX cars with pods. Scaleauto makes a short can Boxer style motor with a 10mm armature that reaches the crown. SC-15/2 25K, part #SC-15B. Drops right in nice and tight and glues in using ShoeGoo by Amazing Goop. The connectors are on the end so it clears all the interior better than the old Slot.it SIMC03 V12/2 29K which is no longer available.
If you haven't tried a motor upgrade in your SCX, along with gears, axles, and alloy wheels, you are missing some fun! I take on Slot.it cars every week with my C6R and win more than my share of races. If SCX re-think their motors and upgrade, I'm confident they could be a leader in the RTR market performance wise!
Here's a pic of it in my Seat Toledo GT...
