So I plan on getting the 19 row Z1 cooler and was just wondering, is getting the Oil Sandwich Plate Adapter with thermostatic and protective house wrapping necessary?

You want the thermostatic sandwich plate.

Cool, thanks. So I guess the house wrapping isn't absolutely necessary.

I don't have the Z1 kit, so I'm not sure what heat wrapping you're talking about. In general, heat shielding is never a bad idea.

Especially in NJ if you drive in cool weather.

True. With an oil cooler, you should also consider a block-off plate for winter driving. The plate covers most of the oil cooler itself and allows the oil temperatures to get up to normal operating ranges.

:tiphat:

Very good points. Any recommendations on one compatible with the Z1 or are they universal?

Some are easier to R&R but it's just a flat sheet of something (I've seen everything from posterboard to plywood to Aluminum to stainless steel used) to block the air flow across the cooler. Ie, whether or not you can mount/unmount it easily is the biggest concern. Being in NJ and using the plate a lot, you probably want something a bit more substantial than paper or wood - Aluminum works well and is lightweight. You should be able to find something designed to work with your setup - I'd try Z1 first - if not, just about any shop that does sheet metal work should be able to fab something up or, if you are a DIYer, all you need is a sheet of Al and a small saw.

I fabricated my own with an aluminum sheet, tin snips and some Velcro.

I'll definitely look into that. Thanks for the info, guys.

Duct tape. Old racers trick. With duct tape you can easily add or remove the tape to get your temps where you want them. ;)

I had the same problem. The Nissan dealer told me the car goes into safe mode at around 200+ degrees. There is no fix for this. It's built into the ECU. I had them install an oil cooler they recommended, $1100 dollars total. The car runs full power all the time now. The oil temp stays at around 180 in city traffic and around 160 on the hwy. This will also extend the life of your engine if you like to drive hard.

Safe mode is much higher than 200 degrees. Think about this- the oil needs to get higher than 212 degrees just to boil off any condensation. 200-220 is ok on this car. You'll see power loss from IATs, not oil temp. And you got boned on the oil cooler. First, you paid WAY too much for the unit and install, especially if it's the Nismo version without a thermostat. Labor was especially rapey. And if the oil is at 160 on the freeway, it's too cold. Cold oil is as bad as hot oil.

A Nissan dealer told me convertibles are faster because they don't have a top.
If you want to learn about how to spend money go to a dealer.
