I was just messing about looking over the engine as TURBO has been lodged firmly in my head for the last week or two. I noticed that the sump has a small "U" hose coming out the front. Just comes out then turns around and back into the sump. Is this meant to have anything on it like an oil cooler? or is it jsut good design by Toyota knowing full well that I would want to turbo it thus facilitating a oil return from the turbo?
Other than coolant, oil and plumbing is there any other considerations for turboing a GZE? Ignition, fuel etc. Just want something reliable and driveable, the turbo of choice seems to be the TD05h, any reason not to go for this? Lag etc?
