Description

my newest addition to my printed builds, the 450ss / r7 based i2! 

at just under 12 hours, you can have a 4 valve per cylinder i2 that can rev past 3000 rpm with the right timing and springs.

some updates will be made in the coming days to remove legoh pieces in favor of a fully printed build.

check the part list for all outside parts required.
