Hi all , I recently bougt a rebuilt Evo 9RS Ti Mag 71 series turbo and I'd like to know how to get the best potential from if and keep the boost level sane .
I've just been to FPs site because I'm also interested in some of the smaller HTA compressors but mainly their flow advancement compressor housing .
They show std 9 turbos with this housing and I hoping its available on its own .

Has anyone tried these housings on std 9 and 9RS turbos and and did it make a noticable difference ?

Also while I'm here can someone tell me what std boost pressure is for 8s and 9s , I believe 10s are 21 pounds ?
This turbo is going on a JDM Evo 6GSR and std they are ~ 0.8 bar or 11 pound on their actuator , my 9RS turbo had a new 1.2 bar actuator fitted .

Thanks , A .
