Yep, I see your point Cam. With the system Terry described on a naturally
aspirated engine, the oil would only be cooled when it is required anyway!
All the Z18 guys seem to be getting around without oil coolers anyway but it is
just something I have had in the back of my mind since building the turbo L
series (with an oil-cooled turbo). It sounds ideal to route the freshly cooled
oil straight to the turbo, then back to the sump (using your method, not
Terry's).
