Oil Coolers

[IanB]

Hi all

Im looking at a few basic upgrades for my GTR and I am considering an aftermarket oil cooler - I have noticed that when the oil is cooler initially when I run the car (allowing for a 2 min warmup before I drive) it runs alot smoother / more responsive and maybe a bit more powerful.

Is this because of the colder oil and if so, is it worth investing in a oil cooler for a GTR? I have heard oil coolers come with their own personal deamons.

What are peoples experciances? Will it help or hinder with the oil starvation problems the GTR can have (I have noticed if you break hard the oil preasure can fall if you dont imediatly stand on the throttle and take off again)?

Your help is appreciated

Thanks

Ian

whts ur plans circuit/drag or just streeter

Oil coolers are great.Just whatever you do,get one with an oil stat.I have hks on both my cars.Oil goes up to temp and stays there.Too cold can be just as bad as too hot.

You will probably find thats your intake temps, not your oil temps.

Most GTR's run over 100c on the track and they still go all day so you may have other issues (bad coils even).

my oil has gets to ~130 deg at track days, don't change the performance or drivability. But I've ordered one of the coolers from the SAU group purchace.

get a proper oil gauge and monitor it under the conditions that you use the car. then find out what the optimum temp range for your oil is. if it's over, get a cooler. just make sure it doen't run too cool when you're not driving hard.

id be definitely getting a oil cooler, piece of mind protecting ur engine components, ive heard that if oil hits above 140 deg the oil looses some of its lubricating properties and you should be changing the oil straight away if that sought of temp is reached.

The temp of the oil doesnt really go up past 90, I got it up to 110 once with a hard, hard run over the mountains but other then that it hovers around the 90 degree mark, up and down depending on how hard im driving / conditions of the day.

The car will mostly see street use with the occasional blast on the track / strip for fun, but I cant risk crashing it in track use as its my a->b car atm.

oil cooler is MORE IMPORTANT than a big intercooller or radiator.

just gat the bigest one you can fit.

with two. 25 row serek coolers my oil temp still gets up into the 115 mark.

the main problem is the factory oil presure relief valves inb the factory cooler and filter block. (4 in total) so anything over 4k most bypasses the filter (and your exta oil cooler)

Jup get is for the GTr i use the HKS oil cooler with a thermostat, and in my country i have a allround year avrage temp of 30 deg, so a oil cooler is a must in my country. even when at night when i drive to work with outside temps hitting 20 deg and im driving at 240km/h on the high way my oil temp hits 110 constantly. and i have a JUN oil pump, and a tomei enlarged sump with baffles, so i have no oil suriging issues. but look to have that thing fitted along with a oil temp gauge.

[T04GTR]

idealy you need to fit the nismo oil cooler adapter.

or remove the factory oil filter block asembly. unscrew the plu on the block and re fit it with a non turbo fliter block asembly. ie no coolant oil cooler.

and use a oil filter that has a relief valve in it. ie. toyota ones z418 etc etc.

The oil thermo stat isn't really needed in most parts of australia. Always allow the motor to come to temp before driving away, you should always do that.

And yes an oil cooler is a great idea for an RB engine

i say any car with an oil temp gauge has oil temperature control problems.. i have seen around the 130deg mark on my lightish tune 32 gt-r on a run through the hills before, certainly dont want to see it any higher than that. preferably around 100-110 deg max. ive got a hks cooler with thermostat ready to go on when i find the time.
