We have had lots of problems with out Skyline overheating on track. We have tried a 19 row mocal oil cooler with no real sucess. We have fitted a Greddy radiator to limited sucess but still the car runs excessively high oil temps (130 degreesC) after 10 mins so we have got serious now. Out came the 19 row cooler sat behind the intercooler and in went a 34 row cooler right slap bang at the front of the car.

It fits beautifully in the number plate recess and a quick trim of the bumper support panel gives plenty of room for the oil lines.

Whether the cooler adversly effects charge air temps to any significant degree is unknown but we are fitting a charge air temp gauge so will know either way soon enough. In the meantime Im loving our latest mod :P

You need to look into ducting, if the cooler had no air going through it then doesn't matter how big it was. But looks like it should do the job there - just make sure a rock doesn't go through it and split it

personally id move that oil cooler to the side, oil runs at a hotter temp than oil usually, and having to pass through first the oil cooler, then the intercooler, and then the rad, the air would be super hot by the time it got to the rad and probably do three fiths of bugger all for cooling..

better off moving it to the side, and ducting/sealing everything up so the air HAS to pass through the intercooler then the rad, and a seperate duct for the oil cooler..

looks awesome, but id cut a giant hole in the bonnet and have it mounted ontop of the bonnet like a drag car's intake.........seriously id prob have it near one of the corners with good ducting and flow.. or maybe even dual oil coolers :mellow: 1 each side

We ran the cooler in the middle simply because the bumpers moulded to take its height at that point. We could have fitted it to one side but we would have to seriously hack into the bumper or wed have lost the top few rows of the core.

We did look at fitting it in the wheel arch but it was going to be a pain and the current position was an easy job.

Theres no real way to get ducting to the cooler when its behind the intercooler.

It will either work or it wont, we will see. The current position was chosen mainly because of ease of fitment. If it effects charge air temps adversely then we will stop being lazy and locate it in the inner wing :mellow:

Our tuner said the exact same thing as you guys, that its current position is a very bad idea but:

A) He said that after we have fitted it

B) Hes never tried a cooler in that position so dosnt actually know how it will effect cooling, hes just making assumptions.

I will find out for sure.

get one of those ARE custom grill fit oil coolers. get rid of the grill and put it in its place...good airflow thats not getting used fully. Right inbetween the headlights.

I cant seem to find ARE coolers anywhere, you dotn have a link do you?

I can tell you now, its a bad idea..

the main thing to fix your overheating problem as ive seen in a number of race cars now is to seal/duct the front end up..

basically ensure that the air has to travel thru the intercooler and then the radiator, and not escape out the sides after passing through the intercooler and loosing all velocity.., the best setup is to have the intercooler pressed against the front of the rad, so its in effect one unit, far far more efficient, even tho there is still some heat transfer from the rad to the intercooler, there is no actual intake temp increase if you do it correctly and channel the air correctly..

did this to a sivlia race car that was over heating and all the cooling issues went away and it sat between 80-90 at all times on the track there after..

my 33 runs a simular setup, with the Ic pressed up hard against the front of the rad support, and the rad in a factory poisiton, the air can't go anywhere then..

personally i think you've gone backawards and will be worse off, but you will only realise this after you hit the track..

If its a track car you dont need those huge round lower lights on each side.

Remove them and put it on one side there where there should be plenty of airflow. Better yet put one each side as someone else suggested.

OK - great minds think alike Ash!

oil runs at a hotter temp than oil usually,

Really???

ARE coolers -$ 1054 for the kit though

He said ARE not ARC...

BTW, Richard of ARE at Brendale is a good customer of mine and his products are simply the best aviable on the market here in Australia.

Why exactly is the current set up a bad idea? I cant see how youll get a better position for the oil cooler itself. We can seal the oil cooler to the intercooler and then seal the bumper to the intercooler so air cant escape round them.

The ARC cooler looks good, I just need to get dimensions.

We have had another look down in the wheel wells and there isnt really room in there to fit a decent sized cooler.

The car is used on track but also drives to the track so I dont want to remove the air con and it has to remain street legal.

I understand the concept of layering the various coolers to minimise disruption to air flow but that would be a very involved job requiring custom intercooler and pipework, plenty of body and chassis modifications etc and its just a step too far for the car at the moment.

    • Well you could certainly buy or build an enclosure for a pod in that corner of the bay. It is absolutely vital that there is a nice big opening to let cold air in to it from the front or underside, otherwise it will just pull air in around the edges from the bay, and if that air is hot, you gain nothing from enclosing the pod. There is lots of good evidence around (including on here, see posts by @Kinkstaah for example) showing that pods pulling hot air from the bay is only a problem when you're static or slow in traffic, and that as soon as you get the car up and moving the air being grabbed by the pod cools down. Although that will obviously vary from car to car, whether there is a flow of cold air to the pod or if it all has to come through the radiator area, etc etc. Obviously, the whole exercise requires as much thought as anything else does. Doing the lazy thing will often end up being the dumb thing. The stock GTT airbox has a cold air snorkel to feed it from over the radiator. Shows that Nissan were thinking. The GT airbox is upside down compared to the turbo one, yeah? Inlet at the bottom, AFM/exit on the lid? That might make it harder to route the turbo inlet pipe using the GT airbox than a turbo one. That would probably be the main reason I'd consider not using it, not that it is too small and restrictive. I'm looking at a photo of one now and the inlet opening seems nice and large. Also seems to have the same type of snorkel that the turbo one has. Maybe all that's required is to make a less restrictive snorkel/cold air inlet, perhaps by punching down through the guard like I did.
    • Also seen this as an option 
    • I get you, we’ll see I’m aiming for 200ish kw now and hopefully 300rwkw down the line after some upgrades maybe like headstuds, E85 flex fuel etc  so trying to make it final for that now, I can get a GTT airbox for $280 so it’s not too bad but not sure if there’s better ways to spend that money. I seen online they say pod filter which isn’t enclosed isn’t good especially for a plus T.      hard to say what to do
    • Meh. How much power can you make from a +T anyway? I wouldn't have though it would be enough to challenge the airbox. It's not as if it's tiny compared with the turbo one. As to putting a pod in a stock airbox .... it's not the filter element that would be restrictive. It would be the air inlet to the box that would be the narrow point, which you could open up regardless of what element was inside. On my R32 I opened up the sort of triangular opening in the bottom front corner of the box, deformed (heated, moulded) some 4" stormwater pipe to fit to that opening and punched a 4" hole down through the inner guard to the spot where the stock intercooler used to be. This was purely in the search for a cold intake, but you could do something similar if you need to open up the inlet side of it. The AFM tube size is the same for both NA and turbo, so the outlet from the airbox is same same anyway. If you're going to do the right thing, then an aftermarket ECU won't care about the AFM (ie, you can get rid of it). But even if it was still there, people pull >300rwkW through them all day, and I suspect you won't be going there.
