So I checked on the net and it says that the 18G turbo flows 600cfm at 15psi of boost. I'm curious as to what t3/t4 trim is equivalent to the 18G? I'm looking at the greddy kit for my 5th gen prelude and was wondering if my top end power is gonna drop off with the 18G turbo or will it pull all the way to redline (at 7psi). Thanks in advance!

Man, it'll pull fine all the way to redline at 7 psi. The 18g is good to 300whp then it'll die off but I don't know if the internal wastegate will hold up @15+psi. But @ 7psi it'll spool up pretty quik and pull all the way

 

where did you get this flow info on the 18g?

Thanks for the info... but I thought the 18G is good for 400+ whp? Just seeing that the DSM guys upgrading to Big 16G can break into the 12's at some crazy boost and they must be making atleast 300whp. The 18G is bigger so should be more efficient, right? I do agree with the limitation of the internal wastegate...might have to port it out a bit hehe. Any more opinions on this turbo?
