Which oil cooler is the best?

allfubarred

I have a 2009 370Z Base with a few bolt on mods. I took it to the track for the first time a couple days ago. It did well the first couple runs but after that I couldn't even make it a whole lap without pulling power and temps reaching 260ish. I plan on taking it to the track a few times a year. I see a few oil coolers available but not sure which to get. I use it as DD as well. Is the Nissan version worth it? I have a friend that works at Nissan and he will let me know his price on Monday. Just looking for help thanks.

Fast Intentions 34 row


you will absolutely need a 34 row for tracking

They are all basically the same in function...the more rows, generally the better. So 34 row is optimal. After that you are looking at construction. All of them basically use a generic oil cooler, or upgrade to a Setrab (very good one). The lines are where they differ and I, for one, feel that the Fast Intentions line construction is the best in the business. I would highly recommend them.

I like my Z1 Motorsports Setrab 25 row with Mocal t-stat adapter plate. You dont need a 34 row cooler unless youre crankin out boosted horsepower and racing. My opinion only. With this setup I track occasionally and hit about 240 deg. tops. Works for me (non-boosted engine). I also went with the protective sleeve to cover the hoses. I don't know how you could get higher quality hoses than these. I was impressed.

Also: This just in! I just now looked at the Fast Intentions Oil cooler Kit. Theirs comes with -8 AN hose. The Z1 Motorsports comes with -10 AN hose which is slightly bigger so probably slightly more flow. -8 = 1/2", -10 = 5/8".

Put on a Stillen 25 row cooler (with thermostatic plate) a week ago and am very happy. Haven't had a chance to really push my car, but in normal driving, my oil temps are 20 to 25 degrees lower. Outside temperature this past week has been in the low 90s.

I heavy track my car and am running the Stillen Race series however it appears Stillen has taken that oil cooler off their website recently

My race grade Stillen cooler was only 24 row, never had an issue eon the track with heat since its install. Typical race was usually out for 25 of non stop use and never went above normal operating temperatures once the oil cooler was installed

I purchased a Stillen 25 row oil cooled kit back in June of 2012 along with Gen3 CAI and Exhaust. Z ran great with no more "Limp" mode at the track. I high speed autocross at Blackhawk Farms Racetrack turning 1:29 times and run my Z hard. Last year I saw a few drops of oil under my Z and found the top of the oil cooler was leaning back about 3-4 degrees and the center row had split open just enough to start dripping. I called Stillen thinking there was no way anything could have hit it being behind the front stock grill. Stillen had not heard of any issues and I ordered a replacement core for $129.00 and put it in. I thought I had 4 years out of it so lets just get it fixed and back on the road. Last night, less then 1 1/2 years after the replacement and maybe 3000 street and track miles I see smoke in my mirror and not 15 seconds later my engine oil light comes on. I pull into a gas station 2 miles from my house, shut down the Z and see oil all over my front end. After a short tow back home I see the oil cooler has once again split open around the middle row but this time I could see the 1/4" slit the oil was coming out of. Before I call Stillen I wanted to see if anyone has experienced this before. One time is enough but twice and this time driving at speed (45mph) makes me afraid to just replace it once again. My towing bill would have been much higher if it happened at the track I was just at 2 weeks ago!

If you go to the track get a 34 row, no question. If you also DD, you'll probably have to block off the plate in the winter in Denver regardless of the number of rows.

Z1 or Fast Intentions. They are both of good quality.

RBfastback

are fast intentions lines really better then z1's lines?
just curious, so far I'm planning on ordering a 34r from z1

edit:
just read FI and z1's website, seems FI went more into detail about there lines and they sound like a better product.
aside from that z1 offers the oil line sheathing for $30.

They are of very very good quality. I have a set on my 1969 VW beetle that go to my external oil filter. Teflon inserts and crimped. They have been on the car since 1992. That is the biggest difference in the kits.

Jumping in to bump this thread, picked up a used Z1 kit with a 25 row Setrab core, thermostatic plate and protective hose wrapping. Could not be happier with the results. Where I would see 220-230 degrees just driving around town on warm days I now have yet to crack 200, but the oil still comes up to 180 nice and quick.

The Z1 Motorsports and Fast Intentions oil coolers are both great quality kits you can't go wrong with either kit. Just make sure you get the correct row oil cooler for what you are using your 370z for.

I mean in DD situations shouldn't the oil reach at least 200F to boil the water off? If the oil remains too cool then won't the water content cause problems? I guess for DD you get the <25 row.

Rusty

Once the oil temperature hits around 100F. The water trapped in it starts to evaporate. By the time it gets to 200F. It's gone. Where I retired from. We used to warm the oil to 110F. before operating the equipment. And kept it under 190F. I wrote the SOP on it.
