Is it necessary to ger an Oil Cooler?

Zyonara91

I've posted it before and I will post it again. Yes.

Daily driving, spirited driving (no track) and traffic jams? - 19 row cooler recommended

All the above plus track usage - 34 row oil cooler needed

Mandatory things to get done to the Z once in you possession unless done so already (in terms of importance):

1) Wheel lock removal
2) CSC elimination kit (Z1 or Z speed)
3) Oil cooler (Get one with Setrab core, check out Z1, Stillen, Zspeed or Fast intentions)
4) Differential bushing change (White line or SPL)

now you know how i feel

Note that the Stillen one will require a different size oil filter

fast intentions and z1 retain the stock size, ALTHOUGH i recently found out that certain brands won't fit because they used a larger size

The Pennzoil filter did not fit on my Nismo with the 36 row Z1 because it is larger than stock. A Wix filter fit fine

I am FOR SURE grabbing the EZ-Street Stage 2 Clutch Kit along with the CSC Delete Kit from ZSPEED soon!

Now can I just get the 34 Row for the hell of it? I'm driving in Jersey traffic and Summer temps averaging between 85-100 a day. No track days whatsoever.

Got Z1 Polyurethane Diff Bushings

What is a "Setrab Core"?

Why does the Oil Cooler kit require a different Oil Filter and not just keep it OE?

The plate bypasses the cooler when the oil is cold (the oil flows straight through the plate). As the oil warms up, more and more of the flow is sent through the cooler. During colder weather, you may want to block some of the air flow over the cooler as few, if any, plates will completely block flow to cooler (no positive shutoff).

My question is what does installing an oil cooler do to a warranty?

I would guess that would depend on what work your having warranted. Same as changing the exhaust, the intakes, tuning it...

MZ DAIZY

I’m still using the stock size. You’ll find out why you don’t want to go bigger if you change your own oil. It’s a bitch getting the filter on and off.

Being born and raised in N.J., I will tell you without a doubt you want a thermostat. Gets way too cold not to have one.

An oil cooler is just a big heatsink for the oil. Setrab core is just a higher quality heatsink - cheap ones can get punctured by a rock while driving, which will really ruin your day.

The thermostatic sandwich plate closes when temps are cool and opens when temps heat up. This helps the oil in the engine heat up faster after a cold start than if it were being pumped through the oil cooler. The block off plate basically is a poor man's thermostat - thin piece of sheet metal and some hi-temp velco on the front of the oil cooler will do the trick - for when the cold winter air during casual driving is cooling off the oil too much.

The plate only shuts off the lines to the oil cooler - the filter is still working. That would a horrible design if not.

The oil pump is what moves engine oil through the oil filter. The oil cooler doesn't turn on and off. When you plumb in an oil cooler to the system, it just gives the oil another path to go. The thermostat controls that path and opens it at a certain temperature.

Setrab is a core in the oil cooler, helps you flex on the haters. I'm kidding, about the flexing part. If you go to Z1 you will see that their oil cooler options gives you a choice between a Setrab core or a Mocal Core. Both are very good brands, however I went with Setrab since it has some high end customers it supplies to:

We supply many of the world’s premium car brands, e.g. Aston Martin, Audi, Bentley, Ferrari, Lamborghini, Lexus, Lotus, and Mercedes, as well as many other vehicle manufacturers, e.g. Bobcat, Husqvarna, Scania, Volvo, and Wirtgen. Our products are also highly suitable for a number of stationary applications

Also the Setrab cost more than the Mocal, just thought I'd share that so you are not blown away. Oh, make sure you get the protected braided lines and thermostatic plate as well to deal with cooler temps in the fall and winter.

All in all I would go with Z1 for the oil cooler, but that's my opinion. Fast Intentions make a wicked product to.

Dude, you're not being annoying. This is a part of the learning process and that's why there is a forum to ask such questions. Just pass on the knowledge to someone else when the time comes.

Background. I have the Z1 34 row oil cooler. Been running it for years. My opinion. There is only 2 oil coolers to get. The Z1 or the FI 34 row coolers. Get a 34 row cooler. The smaller coolers will help, but may not be large enough sometimes. You can always add some block plates if the oil is too cold.

The stock oil filter will fit with the thermostatic plate. Which is a must, unless you are a totally track car. When closed. The plate is still open about 10%. This is to warm the oil in the cooler. The why to this is because you don't want cold oil flowing into a hot motor when the plate opens fully. This would cause some thermo shock to some engine parts.

Oil flow.

When cold. From the oil pump to the thermostatic plate. (About 10% of oil will flow to the cooler and back to the oil passages.) From the plate to the filter. Filter to the oil passages.

When hot. From oil pump to plate. From plate to cooler, Cooler to filter, Filter to oil passages.
