Best oil cooler


Lau

Recommended Posts

Hey guy's,

 

Apologies if I bother with a surely already discussed matter but could someone let me know what the best oil cooler would be for a 750+ supra ?

 

No matter price considerations, just on the physical point of view. Which One gives you the coolest oil ?

 

I see things like xx rows. I see things like xx rows + fan, I see the HKS and other brand kits,...

 

Could someone give me a "scientifical" argument like - in the best case - oil temp curves for a same Supra with different oil coolers...

 

I still have to precise I'm a noob, I of course understand that a 32 row cooler will be better than 16 but I have no idea if the "cooling part" is the only argument.. maybe also a Matter of flow? Oil type ? Something else ? i really don't know

 

Last but not least, same question for Auto transmission oil cooler... Which if I understand well could be the exact same ? It's just a Matter of Space here ?

 

Thank you guy's

You don't want the 'coolest oil', engine oil has an optimum working temperature range and any kit you fit should have a thermostat that only opens to cool the oil if it exceeds a certain safe temperature.

 

The difference with the HKS oil cooler kit is that it's specifically designed to fit the Supra and includes all the brackets, fittings, oil lines, thermostatic sandwich plate and ducting, basically everything needed for the install in the left hand opening of the bumper. It's a good quality kit but because it's a bespoke Supra kit it's not the cheapest http://www.hksusa.com/oil-coolers/

 

It may work out cheaper to piece together a DIY kit, but you'll need to make up brackets, oil lines, ducting, etc. yourself, Mocal are a good quality brand to look at http://www.mocal.co.uk/products.html

Ok now I understand differences between kits and homemade. But I still have no idea for the technical specs for the cooler I need for a 750+ supra. How many raws ? which accessories do I need/should I buy ? Sorry to insist..

 

I'm also a huge HKS fan and up to now I almost installed only HKS, TRD or OEM parts and I would be glad to follow that philosophy again but I want to be sure which exact kit I need (r type, s type,...) ?

The HKS part number for the Supra Type R Oil Cooler Kit is 15004-AT003 http://www.hks-power.co.jp/product_search/product/129

 

Their oil cooler kit is designed to work with their Supra T51R and GT2835 twin turbo kits which are good for 1000+hp so would be fine for your needs. As Dunk says they are expensive and it'd be cheaper to piece together a kit but if you're looking for a quality off the shelf solution then it's an option.

 

Whifbitz (official trader on the forum) do their own kits see here http://www.garagewhifbitz.co.uk/toyota/supra/cooling-parts.html it looks like they include all the hardware needed but you'll need to fabricate mounting brackets and ducting. Might be worth contacting Whifbitz and discussing with them what you need.

Thanks for these informations Nic !

 

I visited HKS Japan last year (invitation of my mechanics) and I have to admit that despite the fact that ordering/delivery is not always easy with them, thay are true passionate people and they know a hell about supra's.

 

What "impressed" me most was the details level of their manufacturing processes and the obsession of building only the best quality. Maybe all this was just a show and lies but then it was very credible ;-)

 

But and unfortunately it is also 100% true that there is a substantial price premium...

 

Anyway I stop to bore you guy's with this... Next thread : best radiator ? Yes I'm in the cooling phase right now...

If it's for fast road usage a fifteen row with a thermostat (vital) is plenty, *IF* it is ducted and the air exits in a low pressure region. For serious track usage you need to be 25 plus rows. Placing a 25 row plus in the front of a Supra is far from trivial. Whatever size you need a minimum of -10 hoses and ONLY swept fittings, but -12 is better and then you can use forged 90 degree fittings if required.

The Think Automotive (Mocal) catalogue recommends mounting the cooler as close as possible to the front of the radiator, because someone has already sorted out the ducting. :)

 

The catalogue is available online as a PDF document, and has a lot of useful info on the different types of cooler, installation, bypass thermostats, etc.
