It's pretty fast if you ask me, but I'm begging for more. I have the following mods...Engine:4.6L SOHC with PI heads and intake manifold.Comp Cams stage 1 camsForged pistonsForged bottom endUnder drive pulliesElectric fanFRPP ignition and plug wiresMAC true cold air intakeBBK 0 weight aluminum flywheel150 WET shot NOSBBK H-pipeCatless exhaust with flowmaster turn downsTransmission:5 speed manualBBK short throw shifterStage 3 clutch 3.73 FRPP posi rear endDo I have to run 93 octane in it, with the mods listed?I want to s/c it, but I've "heard" with the PI heads that the compression ratio is too high. True? What else can I do to this car to get the full potential of it? If I can s/c it, what is one of the "better" kits out there? Would a larger throttle body do any good? A larger cam? Has anyone priced out a KB s/c kit?I'm not sure if this is the stock t/b or not.<img src="http://img.photobucket.com/albums/v319/mazdaboy873/DSC01158.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />And a random shot of my engine.<img src="http://img.photobucket.com/albums/v319/mazdaboy873/DSC01163.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Brenton</blockquote>
