Oil coolers

[eightsixboy]

I am going to be runiing my ae86 at the track soon and thought is should invest in a oil cooler. Can anyone tell me how you do it? I mean i know i need a sandwhich plate and the cooler but were do you get all the stuff from? i have tried bursons and they just looked at me funny when i mentioned a sandwhich plate.

I did some searching and i saw full flow coolers mentioned alot, will it have full oil pressure right after the filter. And do i need a return to the sump? I always thought you could run the cooler after the filter then straight into the galleries?

So yeah should i just go to repco or something and see what they have or should i lok at wreckers for coolers of nissans etc...

Any help much appreciated

Cheers

You'll need to track down a sandwich plate, there's two types, the plain sandwich plate which pretty much spaces the filter and then there's the relocation kit. You have to work out which you would like first. With either ones the oil run from the sandwich plate, filter, cooler (I think) and then back to the sandwich plate then so on, just like it would without a cooler. Same sequence just the section from where it enters the filter and returns to the block is longer.

Try Jamie from Import Auto Parts

Or go to sd.com where he is a site sponsor, he mainly sells them for sr20 motors, however i have been told they use the same size sandwhich plate.

There's 2 main ways to do this.

1. Factory style low pressure, low flow.

2. Full flow, high pressure.

The 1st one comes standard on many Toyotas like ae82, ae92 and camrys. They have a pressure relief sandwich plate which attaches to the engine block and your filter screws in over it. It works solely on pressure and only bypasses a small amount of oil to an oil cooler plate which then goes directly back into the sump. The only plus to this setup is that it's fairly cheap and one trip to the wreckers is normally all it takes to get all the parts.

The 2nd one can be done a couple ways.
a. Full flow/high pressure all the time.
b. Full flow with thermostatic bypass.

Full flow all the time has an aftermarket sandwich plate with at least 2 fittings. Goes in the same place as the factory style one but ALL of the engine oil passes through the OUT line. This line is connected to a high pressure oil cooler plate and returns back to the sandwich plate through the other fitting (IN line). Downside to this setup is it normally takes longer to get your oil up to temp because the oil cooler is working ALL the time. If your oil stays too cold, a cheapo solution is to tape a bit of cardboard over the cooler to restrict airflow.

The thermo bypass way is exactly the same as above expect it has a thermo either built into the sandwich plate or is slotted inline with the cooler hoses. When the oils cold, the thermo will bypass the cooler to allow it to get up to temp. Cons to this setup is that a quality thermo is normally the most expensive piece in this setup ($150-200 alone last i checked).

If doing any cooler install, i'd recommend doing a remote filter setup as well. Makes oil changes a breeze.

A couple of the better setups. I prefer the inline thermo method as it makes it a bit easier to tee into filtered oil for a turbo setup.

I had a hell of a time getting anything decent in Australia that wasn't ridiculously priced, or even some clear information on how to do it. Eventually got my remote thermostat setup from Think automotive in the UK. Admittedly I was coming through the UK from a meeting so was able to save on freight. The guys there were very helpful and engine plumbing is their business.

If you go to their website you can download a comprehensive catalogue with prices plus technical ins and outs on how to design the system and why.

For what it is worth, they recommend a 13 row cooler for a 4age in Australian conditions. And make sure you get a thermostat take off plate. You can also get their own moquip fittings which are much cheaper than aeroquip plus are available for pushon socketless hose which makes it easy to do your own lines at home, you just need a vice.

Or you can get an off the shelf kit.

The Aust distributors for brands like permacool etc were useless.

[Hen is a total nutcase]

Aonther source for a full flow sandwhich plate style (doesn't relocate your filter, just sends the oil to a cooler before it's pumped through the filter) is Meridian motorsports / Aloy race components.. I think they charge $60 for the adaptor block, which is pretty reasonable. But then you have to add hose and fittings.
