pondering.. oil cooling

[viper92086]

as some of you know i'm in the middle of my na-t build and i'm stuck in a oil cooling dilemma, so i have this summit oil filter relocation kit and the whole stock oil cooler setup and it looks like it is in the pics below. But this got me thinkin, after all this oil travels through all this piping, wouldn't it make more sense to ditch it all and just throw the filter straight on the block? also do you think how i have it setup would be equivlent to a 7mgte stock system? or worse

I would be careful with the diameter of that tubing... using the stock setup as a full flow setup I doubt is going to provide enough lubrication. If that is what you're doing there.

^ yea it is what i was planning, so would it be safer to just ditch the whole idea and just run the standard filter? i know a friend of mine with a na-t has been running without a oilcooler (na-t) for quite some time

I have an oil filter relocation kit for my 1JZ, but it linked with an oil cooler. I wanted optimum oil pressure and efficiency, so the unit that bolts to where the oil filter would go only opens up the oil cooler when it is at optimum temp. but always filters my oil 24/7. Hope that helps so what.

not really, cause this is the stock oil cooler, nothing fancy, i really just want to know which would be more efficent running with the oilcooler/oilfilter relocation, or just the stock way with just a filter

I can't make any comment on what temps would be without the stock oil cooling setup on the GTE (some people say it does nothing, I don't believe really anything anyone says any more with stuff like that). I would say it'd be safer to keep up the flow just running the filter right on the stud.

Generally I think people run -10 lines for full flow oil coolers, just for comparison to what the stocker is.

You really should have an oil cooler with a turbocharged engine.

hmm for now i'll leave it as is then if i see that i am getting low pressure i guess i'll just bypass the cooler for now and just run straight relocation kit... cause it is very hard to get ur hand in their to put a filter on

Listen to Nick...you need an oil cooler on a turbo motor
And it is a LOT easier to change oil filters w/ a remote set-up...if you leave the filter at the stock location, you will need the turbo filter head to prevent inference with the turbo compressor piping to the IC.

The way you have your oil cooler hooked up is fine, but realize it will take longer for your oil to reach ops temp without a thermostat controlling the flow. You should have the lines routed block out -->filter-->oil cooler-->block return to run filtered oil through the cooler and protect it as well. The addition of an oil thermostat is a good idea IMO...it will bypass the cooler until the oil is at ops temp.

And as long as you have the oil system apart, put a bypass filter on.

 

[jdub]

^^^ That is an excellent idea

I am slightly confused. If the setup is routed like that with an oil thermostat, then until your oil is at operating temperature it will not go into the filter either. I assume that's bad.

 

[jdub]

The thermostat bypasses the oil cooler to the return until the oil is at 180 deg F or so. The valve inside the thermostat then allows the oil to the cooler.

Most T Stats are 90/10 then 10/90 when hot so you always have Oil in both circuits.

BIG is better when plumbing a full flow system.

 

[theDon]

stock oil cooling system has no valves or thermostat?

for some reason I thought the cooler had to be installed a certain way for flow... maybe i'm tired...

 

[supra90turbo]

I agree. You're better off underflowing an oil circulation system than outflowing it. To have it restricted down to the oil cooler size isn't that good. You're better off getting another oil cooler with -12an lines and adapting down to what you have (-8an?)

OT: I'm digging those IC pipes. Wrinkle paint ftw!

 

[viper92086]

this is what i am doing for now.. just running without the cooler but the relocation kit.. by the scroching hot summer i should have a much better cooler. I did get the car fired up today..... wow it was such a good feeling.. timing could be better tho

 

[jdub]

One more time...and repeat after me.
Don't run a turbo motor without an oil cooler

 

[supra90turbo]

agreed.
