Here is the intake on the LS1 before I got it polished. It will look the same with the new LS3 motor to go in.
The 2 water/meth jets are downstream of the blow off valve about 100mm ie. on the throttle body side of the blow off valve, and out of sight underneath.
Here is the turbo right out the back. Since then we shifted the wategate so it vents straight to the atmosphere and gained more clearance.
and here is the intake from the front looking back
and the car itself, looking as close to stock as possible
