Oil cooler kits ....

[Bender Unit]

Tim,

Did you supply any brackets for your oil cooler out of interest?

Cheers

Biggest issues I can see for the kits are mounting bracket for the cooler, especially if people want to hang it down under the back number plate.

For the relocation kit its also trying to find some spare room near the IC. I will be looking over a stock engine tonight so I will see if there is more space, mine is bad for comparison as I have a big external wastegate in the way.

James I wouldn't want it in the IC side vent. back bumper sounds good. Where is the stock rev 3 one located?

Stock rev3 cooler sits between the block and the oil filter. I think James was referring to the oil filter relocation mounting point when he was talking about a mounting area near the intercooler.

James Have a look at this post <A href="http://www.mr2oc.com/showthread.php?t=1 ... relocation" target=_blank>Oil cooler & relocation kit</A>. Scroll down to the post at the bottom by KingSapper.

Just found this site. Seems to sell everything needed to put a kit together. <A href="http://www.perma-cool.com/Catalog/Contents.html" target=_blank>Perma Cool</A>

Thanks for that information Ed. I was going to use the psuh lock fittings but I my have to enquire about its tolerance to heat as I dont want it coming loose. Swaged ends and Earls fittings look good but cost a fortune.

However looking at that guys install I personally feel the take off plate he has used is wrong, sits far to close to the manifold and the lines will be running very close. The braided hose can actually be heated by the braid causing the rubber hose underneath to blister and melt. I think a heat wrap of some kind is the oder of the day.

Ens,

As Ed said the cooler will sit at the rear bumper, fitting it will be another matter?! Its the Rev1/2 filter relocator that I cant see where it can be located.

Mounting these bits is the real issue from what I can see. Also I didnt really want the relocation kit to go near the turbo etc but then again its no different to how it is, only that with the relocation kit it would be very easy to take the filter off.

Done some more digging and it seems braided hose is no better as I suspected with mot brands actually having a lower temp rating that the non braided hose I want to use on the kit.

What about having it attached to the back grill? I know most people with fancy exhausts chop it away but it'd be a good place.

[Bender Unit]

Problem is mate, that the only way to attach it to the back grill is by zip ties and I would be happy for people to do that bearing in mind that if the cooler comes off then it could cause a rupture in the oil lines and bleed the engine dry.

It seems the only real option is to drill two holes in the boot floor but gain it depends if people are happy about that.

[cantfindausername]

I doubt people will mind drilling a few holes in the boot. The sort of person going for this kit will not be the sort that says.. I dont want to drill my boot

If they did, could it not just be drilled through the boot heatshield?

[MR2Mania]

Has anyone actually measured their oil temps on a heavily modded tubby, to see if extra cooling is actually required?

I've not done so on mine, but a while ago I remember comparing a stock car to one cooled by an SPL kit, and the SPL kit showed higher temps.

As SFLee says, you don't want to be cooling the oil down to 75C or lower, as it's not where the temp should be. You *can* actually overcool the oil!

[MR2Mania]

Additionally, I think the gearbox oil could do with a cooler before the engine oil does.

[Bender Unit]

Already planning the gearbox oil cooler Dino! Thats going to be an easy one, the loop is already there for the take off and there is a perfect mounting point on the box itself right in some decent air flow.

The thermostatic sandwich plates wont open at 75degC Sorry that was my mistake incorrect information.

Would the SPL kitted car be totally standard engine modification wise?

I agree for stock oil cooling is clearly not an issue however for highly modified engines doing track work then it is desirable to have better oil cooling capabilties as you run the risk of the oil etting too hot and breaking down.

TBH though I havent seen one high performance track car that dosnt have a big oil cooler.

No mate, it was modified too (although not massively) - it was Jase at MTTE's old car.

If you've got a decent synthetic oil, it won't break down. In fact, from a bit of research that I did a while ago, you're more likely to get higher oil temps on a high revving 16v NA than you would on our tubbies. I remember my Golf 16v hitting temps approaching 120C, and there were no issues with that car (was running on Mobil 1 and still going strong at 135k miles).

You don't want the oil to remain TOO cool as it'll be too viscous to do it's job properly (which is why you want the oil temp to still remain at a reasonably high temp).

TBH though I havent seen one high performance track car that dosnt have a big oil cooler.

But are you including tubby MR2s in there? After all, it does have *some* form of oil cooling going on?

I'm just a bit concerned about doing major stuff to the oil system if it's not really needed. The last thing you want is an oil leak, as that's a guaranteed engine bay fire if any lines come off (let's not forget poor old Steve Cordiner's car that went up in flames! ).

One bit of advice I'll add is, make sure you've got enough "play" in the lines, to cater for any engine movement, so that the oil lines are not being tugged as you cane the car.

Anyway, I'm sure you'll do a good job though, James...

Jeah James,
I'm sure it'll turn out OK mate,
I'm up for both when you have a conclusive product.
Looks like i'm gonna need it.
I'll be chopping holes away like the channel tunnel in my boot for the TMIC so not too bothered about a few more for the oil cooler.
Also regulating it around 80-90 woiuld be ideal,its true, over-cooling the oil can have just as negative effect as over heating the oil.

i've fitted mine under the number plate, running an inline thermostat so keep everything from being undercooled.

They were listed on twosrus for the last 3 years

Oh well, never seems to be any great interest so won't be buying anymore again i don't think.

I just used the last one on my own car.
