Single Turbo Blow through Small Block Kits???
I can tell you I have nearly $600 in the hotside including the 5" downpipe I purchased from MadDart. Thats just the materials including all the 3" mild steel .067" thickness mandrel bends(two 7 piece kits), 6-3" V-band clamps, 6-3" V-band flange kits, Jegster header kit and header flanges. Plus a minimum of 15 hours in fabbing!
This is mild steel, imagine if I used Stainless! Bet it would have been triple the cost on the materials!
