Nissan Motorsports Oil Cooler vs. Stillen Oil Cooler

Dustin@Z1 · 09-30-2010, 09:37 AM

Just food for thought on the Z32 Oil Cooler. I have a NA Z32 Slicktop that I run as my DD/Track Car (which is an oxymoron I know). I installed our new Z1 Full Flow Oil Cooler on it with a 25 row Setrab Core which is significantly larger than the OE TT unit.

Doing two of the 20 minute run groups sessions at the Z Nationals track event at Little Talladega Motorsports Park this past weekend, I saw oil temps of about 200 ~ 205. Keep in mind that this is on a NA. I was unable to find anyone at the event with an oil temp gauge on a TT Z32.

That's good info. 200-205 on an NA on a track is damn goodl

My 280ZX Turbo used to get up to 230 when fully beat on.

Knowing the guys at Z1, I bet one of you will put a gauge on a Z32TT just to find out! Since the TT's turbos are also water cooled, it might be close to your temps.

What was the air temp. at the track that day? Just wondering. I have noticed these temps in 80-85 degrees. When it is around 100 degrees I see 220-225 on my DE events. I have a Nismo 34 row cooler.

Dustin@Z1 · 10-07-2010, 09:53 AM

The air temp that day was easily in the mid to upper 80s here with little cloud cover to speak of.

Keep in mind though, these temps are on an older 300zx Non Turbo. The oil temps on a newer 370z are going to be higher. The 34 row oil cooler seems to be doing its job if you are only seeing 200-225 @ 100 degree air temp. How long are the run sessions for? An ideal oil temp is really between ~ 185 on the low side and ~200 to 210 on the high side.

In the case of the 370z. Just being able to prevent the engine from going into "Limp mode" and away from the 280 degree mark is ideal. I have heard cases where people all over the country get their Z's to react that temp just in a spirited mountain drive.

Do I need a thermostat?

I've had my new Nissan Motorsports unit all of one week today and I have noticed a dramatic decrease in oil temps but I also have a new short block so I am under break-in with a 4,000 rpm limitation. I saw temps of 245*F during break-in, on my original engine. Now low 200's.
I've read the entire thread and do not think I need a thermostat for my oil cooler, but I will ask. I live in the California bay area that has only snowed half a dozen times in 30+ years, and it does not last on the ground an hour. Temps range generally from high 40's to mid 80's. Do I need a thermostat? Thank you.

Thanks for the clarification on the 300zx. I didn’t realize that.

My run times sessions are 25 minutes. In the spring when the outside temps are less than 90 degrees it indeed runs in the 185-195 degree range. On those summer days when the temps are over 100 degrees and the track is well over 150 degrees, 225 was the max I have seen.

The cooler is a must as you know if you track the 09-10 Nismo.

There are indeed some situations where people may find that they will not need a thermostat. But keep in mind, a thermostat serves TWO purposes:

1) To help regulate the temp and help maintain a proper operating temp (which is what this thread has been about primarily).

2) To help RAISE the temp of your oil quickly and safely (in a controlled manner). You could run without one, but on some cooler mornings you will have to take it easy on driving longer to ensure your oil temps come up to the proper temperature range. The thermostat restricts flow to the oil cooler when shut, bypassing ~80% of the oil back into the engine. This helps keep the warmth of the oil inside of the engine until a desired temp range is achieved.

My 25R runs 90 degree more than ambient temp. Even though my thermostat is 180F, but I can easily get down to the 150-160 range on a cold morning in the 50s

Thank you. Sorry for the slow response. +1

So help me out. If I plan to do light track duty and mostly aggressive street driving, will a 19 row oil cooler work? Or should I go for a 24 row?

I think a 19row will more than enough for light track

I order a 19row

Given where you live I'd go for the 24 row.
