yes i have a black Si and live in belleview, and yes i bought everything from doug(endless speed and sound)yes i bought everything brand new and name brand. i wanted to get everything to ensure the life of my motor when purchasing the turbo kit. when i bought everything it wasnt just 6 grand that was including labor, i paid around 4,500 for all the parts and the rest was labor.As, for letting Mark look at the car.......i dont think that would ever happen, he doesnt get along with my Fiancee, for reasons i dont know. ok now for my suspension the only mods i have are skunk2 camber kits on the front only, agx adjustable struts on all 4 corners with Nuespeed Springs, as well as a front upper and rear upper strut bars, thats it. and as for my rim/tire combo i have tenzo shu 4 copys with khumo 712's(205/40/17). the 1st and last time i went to the track i ran twice the 1st time i launched at 2,500 rpm and the car just bogged down, the 2nd time i launched at 4,500 rpm, and spun all 1st 2nd and churrped 3rd, then the lines got to long and i called it a day. But when im on the street i have no problems. its just that it feels like it pulls harder on the street rather than on the track, maybe its just my tires or maybe the track surface is too sticky here in Gainesville.
