I'd consider a small one mandatory for street use, as long as it's used with a thermostat to bypass the oil cooler until the oil is up to temp.

You need to ensure that the oil cooler core has good ducting into / out of it to ensure that you are maximizing it's ability to shed heat from the oil to the ambient air.

Kind of like this:

Forget the second trans cooler you posted, they only really work as trans oil coolers on hotrods IMHO.

The first engine oil cooler you posted is ok....however I would avoid it due to the fact that the fan attaches to the cooler by those zip tie mounts; not good. Since the cooler core is aluminium, those zip tie mounts vibrate / jiggle and consequently wear through the cooler core, resulting in pin hole leaks.

Go for the Setrab unit at the bottom of the page, the 119FP: http://www.anplumbing.com/Extras/Setrab+Coolers-21.html

It has a proper fan shroud (and therefore decent fan mounting to the core), and even if you don't or can't get ducting to it, you can wire in a temperature switch to kick the fans on, when say the oil temp reaches 100 deg C, that way you can still cool the oil in traffic.

Look at summit racing too, they have heaps of oil coolers with fans listed.

I would also go for an oil filter relocation kit and not a sandwich plate adaptor.


Don't get me wrong, you shouldn't rush out to get an oil cooler ASAP, there are plenty of big power street engines around doing fine without oil coolers. If you plan on taking it to the track, then I would invest in one.

thanks mate just the advice i was after, i was thinking of mounting behind the second thermo rad fan, i have a pwr transmission cooler mounted this way at the moment, not with those shit clips, but aluminium strips. i guess you may as well put the filter in a more accessible location..

Guys, this is of interest (the thread) to my car which I am going to be working on heavily for the next month and a half. I will be finishing up work so want to get the car finished as the project has gone very slow.

What sort of power are we talking about to have an oil cooler. A lot of turbo cars producing 200kw @ wheels aren't running oil coolers. I would think they would be for more serious power applications.

How much fabrication is needed to run it through the U12 and what is involved.

as suggested, it will help lower engine temps and also turbo temps, probably don't 'need' it but it will be of benefit.It should be a matter of removing oil filter ,fitting the blanking or blocking piece running lines to cooler, then to filter which you find easy access spot, then back to the blanking plate. I will be adding the install of mine in my project thread when i get it in the next few weeks. I think that's how its done...

A lot of those cars have them standard. I know my SR20DET has a small oil cooler on it. Its at the back of the block, its about 150mm round and maybe 30-40mm deep. Oil flows in and out through the middle, and coolant flows through the outside of it.

i after much deliberation decided to put an oil cooler on my car as it was deemed to be a good thing, i bought a thermo controlled unit and put it on the car so far so good, NEK MINIT it broke on the second run of the day on the fastest corner of the track, dropping oil on the track spearing me off the track in my own oil wasnt good. Now dont get me wrong i dont think they are a bad idea but i think a plate system needs to be made at the back of the block where the connection is for the for the standard aluminum part that goes up for the filter, this part i speak of is not strong enuf to support the extra weight of the adaptors by the look of it as it is only made out of very light alloy, and before you go out and buy one for a GTIR or normal sr20det they dont fit as they have a differnt mounting system to ours. I still think they are good but beware.

Not good Laurence.

The remote mounted filter way is better for integrating an oil cooler, not so much strain on the filter feed tube. The derale kit I bought a few years back was only 100 from memory.

I think I may need to get an oil filter relocation kit just so I can easily change my filter instead of trying to manoiver around the individual throttle bodies. There are kits minus the lines and cooler for like $30 but I doubt their quality.

Can someone source me a good kit, for A decent price... Nothing too expensive.
