Found out I get hook-ups on Drag kits too.

Here's what I'm looking at.
Full Drag kit, including BOV and Intercooler for $2,650.00
or
GReddy kit, no BOV or Intercooler for $1,820.00
I can get the GReddy BOV for $160 and the intercooler for $594 or $750 for the larger one. So, with the BOV and IC I'll basically be right at the $2,650.00 that the Drag would have cost.
So, which kit is better? Which kit is more reliable?
