just bought jdm gsr but i'm not sure if the bottom end is stock. how can i tell what mods were done to it if any?

 

completely dissasemble the motor.

 

then just measure everything and look up the specs? **** that sounds like a lot of work. any1 else know an easier way?

 

There is no easier way. You could pull the head, then drop the oil pan. Then you would be able to see the rods, pistons, and valves. But believe me, that is a lot more work than just pulling the motor and then dissasemblling it.

 

thanx i guess thats all and is a must before i take it to the tracks or go on the bottle
