So fuck ebay parts, but I love ebay. I bought a Precision 350hp, broke a tab making a mount for it. Then tucked my manhood and bought trackspeeds. I mean why not? I just spent $700 on his radiator...2.5" 45 with mini 45* ss elbow I cut. Welding a reducer cone to taper down to 2" which is the O.D of the compressor outlet. So 2" most of the way to the intercooler inlet, and about 10" of 2.5" and 3" of transition between.
