I do agree with you and we have suggested this in the past to many of our customers and forum members here on the370z. Owners of Z/G's living in cooler climates or in the winter with ANY oil cooler should consider blocking off the front of the core during the cooler times of the year. This method is used widely by racing teams to further regulate oil temps.

Race teams will block off individual rows of the oil coolers during test and tune to "fine tune" oil temps depending on the track conditions, humidity and driving style.

Does Z1 sell a core block off plate? If not then are there any photos floating around of a mock up block off plate on how to fab one?

We don't have one just yet but I'm sure there is a DIY somewhere on this forum.

Based on Dustin's comment it is possible that the mocal thermo plate is in fact working properly. I blocked my cooler (will post that in DIY) and observed a freeway oil temp of ~210f suggesting a 40-50 degree temp delta across the cooler. So when the oil temp is just rising off the 140 peg it is likely that the inlet (and sandwich plate outlet) temp is 180, as it should be. However if the unblocked freeway outlet temp is 160 that is still the temp of the oil heading into the engine for lubrication, which may still be a bit too cool.

Thanks, my oil cooler(s) arrived today. Will search around for a block plate.

At what temp does the mfg rate the sandwich plate to open?

Here are a couple, pretty much the same with additional mods and more in detail on the second link.
