i am not totally sure the diffrence between the 20g9-5, 20glt and the fp green turbos?someone fill me in..or on the other hand which of the 20g's makes the most hp?thanks ahead of time

20glt and fpgreen is the same thing and that is the one you should go with, not a doubt about it.

so what is the 20g 9-5?

i want those most powerful 20g and i am looking into getting it ported if that will yield more whp gains

it is the old 20g that buschur modified and the 20glt is the new one that fp/buschur modified which is a great turbo.

all the hype that you are reading about the new 20g is the new 20glt/fp green. capable of 10 sec 1/4 with the right supporting mods.

a perfect guy to talk to about this is buschur - www.buschurracing.com

so the 20lt is def the most powerful one

YES, the LT after it stands for large turbine. if u want info on it go to forcedperformance.net or Buschurracing.com

20G-LT is the same thing as Evo Green. The 20G-9-5 is the previous version. It has the same custom-cut compressor wheel as the green, but the stock turbine wheel. The green has a custom turbine wheel too.
