Im wondering what yalls suggestion would be for a guage or wall thickness of piping to use as a j pipe to support a t3/t4 turbo. I weighed the turbo by itself at 14 lbs. I figured that the extra hoses and other small misc stuff would add potentially another 1.5-2 lbs max but then the down pipe would be the big factor is this instance. Do you think 16 gauge would be enough, would 11 gauge which comes out to be roughly 1/8 wall thickness be better? im gonna be using the stock style manifold with a trussed 2 bolt flange to the standard T4 flange. What are you guys running?
