The car it a 98 itr. It has arias 9:1, eagle rods, port and polish and 3 angle valve job, ported intake, 3'' downpipe to a 3'' cat and just a N1. But I have the greddy kit so I know I will need to run alittle more boost so I'll be using the ems, 3 bar, 680cc or bigger. I have a clutchmasters stage 3, turbo timer, gauges etc. What else do I need to complete the set up? The goal is to run 300whp and to have it last a while.

What is the max cfm the 18g can flow?
