There are coolant plugs under the spark plug galley cover. The four giant hex bolts are plugs to oil passages, you need to remove those to get to the coolant ones below the cover.

Oil feed is easy, there's a plugged 1/8 BSP oil pressure port between the oil pressure sender and the thermostat neck... actually, it's right behind the thermostat neck.

The return is troublesome. You need it as high as possible, but there is NO drilled port for it. The two possibilities are having a machine shop drill the boss (as it is on the GTE... MUCH preferred!) or drilling the oil pan as high as possible and welding in a bung... this MUST face a main, not a rod or weight and it MUST enter angling downward (it is a gravity drain).

Coolant's easy, there's a bypass which is employed to relieve suction on the thermostat that's on the thermostat neck. You'll notice it by the huge banjo bolt on the right side of the thermostat neck and it goes down to one below... ad hose so that that tiny circuit now runs through the turbo.

I have no idea what the hell you're talking about... First, you don't have a MAF... you have a VAFM (there is a difference ). Second, the GTE has a KVAFM. The only 7M's which didn't have one of these type of AFM was a certain model race car (which never left Japan, AFAIK) which utilized a system which calculates air mass based on temp and manifold pressure like the 1JZ-GTE and 2JZ-GTE use (2JZ-GE uses a KVAFM).

You can delete one through the use of additional hardware, but without any such devices you'll have an AFM.
