OP, if you see temps in the 240's. Get an oil oil cooler. The ECU will start to pull timing at 240F. And go into limp mode at 280F. Get a 25 row. If you want to push it. :driving: Get a 34 row.

As for the oil to be at 180F is BS. :shakes head: Once the oil has hit 110F. The moisture in the oil will start to evaporate out. By the time it's at 160F. It's almost all gone. Remember, you're only dealing with 5 qts of oil. Not 7,000 gals. Oils work best between 130F to 190F. The engine has to operate at around 210F because of emissions. To help lower NOx emissions. The combustion temps have to be higher.

After I added 40rwhp from exhaust,CAI & Tune (not to mention 19x10’s/12’s w/285’s & 345’s) I had a tendency to stay in the gas more....210* is a normal cruising temp for me & it escalades when I hammer on it.
I try to avoid sitting in traffic on a 95+ temp day/as this will push it up
As well.....@230’ish I’ll back out the throttle-as I have seen 240/250
In the past.
Gonna add one this spring/as some hard spirited driving will push it up rather quickly.

So I've pretty much decided to move forward with this. Thanks to everyone that contributed. Last question.. Which one?

Z1 - 34 row with Setrab core / thermostat plate $599

Fast Intentions - same set up $618

Both the same? Either one seem to have a better reliability than the other?

One was easier to install than the other? Customer service?

Flip a coin? :icon17:

Thanks

I don't know how reliable the data is, but there have been some complaints recently about Z1's customer service. I have never read anything negative about FI ever.

Personally, I have bought from Z1 a bunch of times and had excellent experience. I have never dealt with FI.

I've bought from both and never had any issues with either one. :tup:

Quality of the products the same?

Fitment the same?

After really digging into what you get it looks like the only parts that could be different between the 2 companies are the hoses and brackets. Setrab oil cooler isn't theirs, mocal thermo plate isn't theirs, that leaves the rest. Am I off base?

you're spot on. If you feel good about making your own brackets and hoses, you can do it a little cheaper yourself. All of it is pretty DIY friendly.

One thing I like about the Z1 kit is that they provide an optional hose wrap that protects the steel braiding from fraying, but like everyone else said...the oil cooler cores are the same between FI and Z1...the lines and fittings are going to be the major difference. Brackets are usually from the same manufacturer as the core, I'd be surprised if FI sells their kit with a non-Setrab bracket, I know Z1's is.

With alot of reading, some great input from the good folks here on the forum and talking with a gear head buddy of mine I believe I've finally reached an answer I'm happy with. Hopefully in the future when someone searches the forum for oil cooler info this posting will help.

I realize there will be different driving conditions, tracking / spirited driving / grandpa mode (ME when the wife is in the car), different areas of the US people live, etc. All of these things should be considered and will ultimately effect the final decision of what a person buys. With that said the below info certainly is not an end all answer, but hopefully it will bring things into focus for many and reduce the amount of leg work they'll have to do.

19 row - waste of money

25 row oil cooler - the place to go is Z1 Motorsports. Setrab oil cooler and mocal thermostat sandwich plate - $523. Wrap over Stainless steel lines $35 add-on optional.


If you want a 34 row oil cooler go to Fast Intentions, they only offer a 34 row. I called them, they used to offer both a 25 row and 34 row but the gentleman I spoke with said the 25 row often did not meet the racing needs of their customers. Setrab oil cooler and mocal thermostat sandwich plate - $599. The same set up at Z1 - $628.

Fast Intentions have better hoses- teflon inner liner. I called Z1, their hoses are "elastomer" which is much better than neoprene but not quite as good as teflon lined. Fast Intentions does not offer optional wrap over SS lines. Brackets and screws are brackets and screws.... same either place. At the end of it all everything is the same except for the hoses. Oh yeah, customer service. Seems both have good reputations.

As many have done both the Setrab oil cooler and Mocal Thermostat Plate can be bought individually from other sources. Make your own hoses and brackets if you want to get that deep into it. Cost would cheaper, not sure how much.

That's my story and I'm stickin' to it. Yep there will be lots of opinions. Jayhovah and Eagle were very helpful to me in the end, THANKS! Thanks to everyone for reading and their input. I'm off to order me an oil cooler. :tup:

Nice write up. But in a month or so. Someone will asked the question again. :rofl2: Well..........are you going to get a cooler or not?

My answer to the oil cooler question is the same as is with wheels and tires...."Go big or go home." 72 row for me lol!

Been some used units in the classifieds lately. As long as the core hasn't been punctured or an engine blown its guts in it, you're good. I got a 25 row setrab w/thermostatic plate, lines etc. shipped for $300 last month.

I live in chattanooga TN. Trust me when I say if you drive your car more then 20 min in the summer you need a oil cooler. I have a 25row and love it.

I was trying not to ask but....

Tropical climate, NEVER sub 70*F, 80-95*F most times. Currently stock but will be doing R35 turbo conversion ala Husam's kit. Plan to get koyo rad whenever it's released.

Daily driver, 1/8th mile drag once a month and auto x 6 times for the year sub 45 sec courses.

25 row or 34 row?

34, no question. With what you have planned. A 25 would be a waste of money.
