I think they're 16G's but I dont know too much about them mate, but hopefully this helps you.
I know the spin in the reverse direction to the Evo 1/2/3/VR4 turbos though. http://forums.nzmmc.co.nz/viewtopic.php?t=41465
Hi Dre. I'm up to no good ;] nah mate, I picked up my 20g'd 16g.
I was curious what Mitsu used after the 16g & what cfm they jumped to.
You know what I'm fabricating for the in & out.
