hey all im having alot of trouble finding a hole to stick my oil cooler any picks or info of where yours is would be extremly helpful as mine cant go at the front as i have a Massive aftermarket fmic,

cheers in advance pete

I had a similar problem; i thought i'd never fit a 19 row oil cooler at the front, but after playing around a bit, it is possible. Not sure how your intercooler pipes are, but i had to cut mine and add a slight bend so that it went under to oil cooler core. No big deal. My intercooler is 100mm thick with 3 inch piping. Ive got the oil cooler, air horns and a 50mm bov in the inner guard now.

The oil cooler is an Earls item, and i used the earls mounting kit with a custom bracket that i made.

That is one of the best installs i have seen. Its a credit to you or your mechanic. So many people install their coolers in a way to damage them after hours of use hot

roy, im interested to know what u mean by this, are u talking about the positions of the inlet and outlet being at the bottom of the cooler as opposed to the top of the cooler?

and how does the cooler get damaged?

Ditto.

I got one of those R32 GT-R HKS kits and it mounts on the left hand side in the air duct.

I still see up to 130deg oil temps at the track on a high twenty's celcius day though. It's a 16 row cooler.

I think those long studs need crush tubes, so when you tighten it up it holds the ends of the core securely, rather then trying to crush the core.

I agree with GTR1993, how there would be a large air pocket in the cooler unless the return line is at the top, so it air bleeds itself as oil flows thru it.

I'm trying to put one of these in my 32gtr, but i haven't seen a way to deal with the air after it leaves the cooler. all these pics show good air flow to the cooler, but there is no way for the air to leave.

But they manner in which he has attempted to support the lattice arrangement of the cooler is a step in the right direction. If i could have scored some half inch alloy tube i would have cut it to length and used it on the inner part of the cooler so that as you suggest, you dont over tighten and crusch the core.

The easier solution which is all i did was put a nut on the inside of the length of all thread and tighten up to that.

But the reason i like the install is because the cooler is nicely supported with the alloy angle/channel and the mounting uses allthread accross the entire height meaning that when the core gets hot and is full of oil (heavy) over time it doesnt distort and damage itself.

If you look at cars for sale that are a few years old or done plenty of kms its not unusual to see their core all stretched and out of square. I have also seen one fail at the track causing oil down because the core was stretching under the heat and load while racing. Another core fail when the braided lines cause a load on the connection, when it heats up it bent to the point that the core fatigued. Again this was a race car and i noted that my core has been damaged over time as i used a 90deg bend and forced the braid to make up the rest of the angle. Shoudl have useda 120deg bend that way there would not have been any tension in the connection that when the alloy heated up was easily distorted.

Another core in the inner guard had a rock go through it as the inner guard was removed. I think the stone was thrown from the tyre forward as the damage to the core was at the rear. This is another thing i am wary of as i havent run an inner guard since i resprayed the car. Just havent got around to putting it back on....though i should. A had abit of alloy mesh cut into my guard so air coudl still escape whilst being protected from stones and other rubbish. When i duct up the front of the cooler to the new bar opening i will also put mesh on the front to stop a rock going into/through it when following another car, which is most likely ever going to happen at the track (i suppose)

And lastly i saw a car at a track day that damaged the core which ended up splitting as it was mounted a little too close to the bumper / vibrating and it ended up rubbing to the point that over time it eroded the core and split.

LOl, so just some general comments on things to consider. LOL i know my install is short on two of the things noted above :rofl: But i will get around to it, hopefully before it causes me problems. But thought i would just pass on some of the failures/damage i have noticed when looking at cars, attending track days and when i use to scrutineer cars

the best way I reckon for 32 GTR is as per jenkies one. mine is mounted that way too (it's a trust kit too) and I haven't had any problem with it in 4 years or so of use. one other piece of advice for jenkies is you need to open up the inner guard behind the core so the air can escape. either cut a section out and replace with mesh or swiss cheese it with some 30mm holes.

I used to have mine mounted behind intercooler and in front of radiator...a big no no!

now i simply have it mounted in a box up on a high shelf at the workshop with other assorted nick-naks. :yes:

      Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
