Which is bigger td05-18g(greddy) or TD05-16G(very common mitsu upgrade)...the reason i ask is mitsu people are pushing over 300whp easily with thsi set up. so if the greddy is bigger or same is that, it will problay work for me.

 

the 18G is the bigger wheel with more hp potential.

 

18G has a bigger compressor.. neither is a "greddy" turbo.. both are Mitsubishi's.
