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.

    • And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!
    • And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.
    • Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).
    • You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
    • OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
