About to go thru the motion of a single turbo install on my 350Z. Been unboxing and preparing and checking and rechecking and I found the "Y" pipe was incorrectly manufactured. After a few days scouring Youtube and other info outlets I stumbled upon a vid of a fella doing the same mod and the issue with the "Y" pipe. Just waiting on the welder now to close it back up. Makes me wonder how many people may have the same issue and did not correct it, which is strangling 1/2 of the motor.
