also another question. will I be able to achieve 400hp on 93 octane? Im thinking of building my own intake manifold. i think oj perfromance had weld in injector holders. I know a tig welder and my step dad works at a shop were he can get any type of metal tube also, and lots of scrap metal and a polishing wheel too so i can mirro that thing up. The aftermarket ones are so high priced and i really wanted straight runners that I figured I could build one cheaper and of better quality. Didnt I read somewhere that smaller diameter longer runners would promote better low end power where as wider shorter ones would help top end? q45 flange for throttle body or will a q45 throttle body be overkill? I have one laying around beautiful new looking been in a box forever. also what injectors should I use. I have read bad things about deatshwerks injectors and venom are shit supposedly. nismo ones any good? what do you guys use? i wish I could get this whole degreeing thing with cams down on top of intake and turbo manifold designs ect. Am I able to dial in certain parts of where my power band will be by changing things like runner dimensions and turbo manifold designs, cam tuning ect so I can get more consistent power threw out the entire rang of RPM?
