also i noticed that in the commonly asked questions, i looked at all the different mitsu turbos and the various outputs at vasrious psi, but what i didnt notice was an TD05H 18g turbo and its outputs. i can figure its somewhere between big 16g and 20g. but was wondering what psi they were effecient up to. i have the forced performance 18g turbo thats ported and clipped and was planning on only running 15-18 psi with RC 550,s-acf2, and a walbro 255, but if i can go more i will.
