AlanM Posted February 10, 2007 Share Posted February 10, 2007 Am I correct in thinking the thermostat is in the line going in to the cooler? Quote Link to comment Share on other sites More sharing options...
SUPRASUZUKI Posted February 10, 2007 Share Posted February 10, 2007 The thermo can be integral to the sandwich plate or within it's own housing fitted along the pipe runs to/from the cooler. Quote Link to comment Share on other sites More sharing options...
JohnA Posted February 11, 2007 Share Posted February 11, 2007 Two points: These remote-location filter kits introduce the possibility of extra leaks. Some are poorly designed and have the filter sitting upright. This is a no-no. Quote Link to comment Share on other sites More sharing options...

Ark Posted February 12, 2007 Share Posted February 12, 2007 ...have the filter sitting upright. This is a no-no. Why? That's a serious question by the way, because I've got a kit to fit ATM. Quote Link to comment Share on other sites More sharing options...
JohnA Posted February 12, 2007 Share Posted February 12, 2007 Because the oil will tend to drain out of the oil filter when the engine is stopped. You want the oil filter to be FULL the moment you start the engine, otherwise the turbo bearings will be fed bubbles during the time it takes to fill the oilfilter (several seconds). This leaves light scar marks on the turbo shaft, and the more times it happens, the deeper the scars get. It is non-reversible damage. The manufacturer has the oil filter at an angle for a reason. ;-) Quote Link to comment Share on other sites More sharing options...
Ark Posted February 12, 2007 Share Posted February 12, 2007 OK so the next logical step from that is the assumption that the filter should be as close to the bottom of the sump as possible too, so that the oil won't drain out of the pipes leading to the filter... Plus the term 'upright' was slightly confusing too, as that could mean upside down or right side up, but still vertical... So...good locations anyone??? I'm thinking of the gap under the passenger headlight - just drop the undertray to access... Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted February 12, 2007 Share Posted February 12, 2007 You can get filters with anti drain back valves. I have never fathomed this obsession with moving the filter form its stock location, personally. You are just adding unions, hoses, weight and complication for no good reason.

Ark Posted February 15, 2007 Share Posted February 15, 2007 I can't understand why people don't just use a thermostatic sandwich plate and leave the filter where it is. There's little enough room for the cooler, let alone finding a home for a remote filter head, as well. A lot of the off the shelf kits use 5/8 bore hose, which, IMO, is too restrictive for a 3 litre turbo engine with it's serious oil pump flow. I would always suggest you use 3/4 hose and fittings (-12) with a cooler with the appropriate size unions to match. I even had one Supra in with 1/2 lines and fittings, with a big end knock, needless to say ftp://ftp.chriswilson.tv/Skyline_Stuff/skyline_oil_cooler Nice thing about Skylines is there's loads of room for stuff like that! FWIW, I just measured the lines on my HKS kit: -12 Quote Link to comment Share on other sites More sharing options...
SUPRASUZUKI Posted February 15, 2007 Share Posted February 15, 2007 FWIW, I just measured the lines on my HKS kit: -12 When you say measured, do you mean the internal diameter of the pipe? What was the actual measurement? Quote Link to comment Share on other sites More sharing options...
SUPRASUZUKI Posted February 15, 2007 Share Posted February 15, 2007 Just checked here http://www.racerpartswholesale.com/aero.htm for reference. -12 pipe has a bore of 0.69" ( 17mm give or take) Quote Link to comment Share on other sites More sharing options...

Ark Posted February 16, 2007 Share Posted February 16, 2007 I don't know the internal bore - I read the wiki page about AN sizes and apparently it's all down to the OD (ouside diameter) which in this case is 3/4". They appear to be standard aeroquip armoured lines though, so whatever they are spec'd as. Quote Link to comment Share on other sites More sharing options...

paul mac Posted February 16, 2007 Share Posted February 16, 2007 I'm not 100% sure that you need an oil cooler. I can't think of anyone who has actually measured oil temps and found them to be a problem. i had a few occasions last summer where a cooler would have been usefull on stinkin hot days as the oil was cooking and i had to slow down to keep the temps reasonable which is totally unaceptable lol, as long as the cooler is thermostatically controlled i see it as a benefit (mines in the garage waiting to be fitted) Quote Link to comment Share on other sites More sharing options...

I'd also agree that if you've got a stat in the system you can't really go wrong as you shouldn't run too cool. The reason I'm contemplating one is it will help the engine coolant by removing the heat input from the oil. The same reason I'm thinking of a tranny cooler too.

My gauges are coming together, closely followed by decats etc. I want to 'baseline' my temps before upping the power. Quote Link to comment Share on other sites More sharing options...

Guest TeCKis300 Posted January 17, 2008 Share Posted January 17, 2008 Now how many of you that have high oil temps run a full size intercooler that covers the full grill? Oil and water temp go hand in hand. High water temps will make the stock oil to water cooler more inefficient. Quote Link to comment Share on other sites More sharing options...
supradibbs Posted January 17, 2008 Share Posted January 17, 2008 must say i fitted a 16 row cooler with -12lines on my single and it made alot off diffrence to the oil temp Quote Link to comment Share on other sites More sharing options...
