ok, now that i have progressed to the point of building the motor back up, i need to know if anyone knows which direction the coolant flows through the engine (1jz). since im going single and its watercooled i need to know which ports to block and which to tap and install some AN fittings. i think the 2 ports on the upper water neck with the 2 pipe nipples on it are the turbo feed (for coolant) and one return (turbo 1 front) goes back to the w/p and turbo 2 (rear) goes to the hard pipe (shape of a U that wraps around the block) then goes into the oil cooler then to the block. if im right please let me know if not then correct me please. thanks for the help.
now for the 2nd question. which ports do you use for feed and return? i dont have a problem drilling and taping
