Just wondering if it would be advisable to run an oil cooler on my future setup. I have an ls6 w/317s and will have a front mount MPT70 going in a 240sx. I'm in south MS so temps are usually in the 90's all summer. The motor isn't in yet so it wouldn't be that much more work to go ahead and install an oil cooler but it seems like many people have oil pressure issues with turbo setups anyway.
I thought I might put it in without the cooler and just monitor my oil temp and put one in later if I need it and my oil pressure will tolerate it. I would rather not use one if I don't need it but just wanted to hear some thoughts/opinions/experiences.

Oh, and I will be running a ported ls6 oil pump.

I dont have oil pressure issues and it has been 90-100 degrees here in NC the past month and a half.

I do run Amsoil Z Rod Full Synthetic High Zinc formula 20W-50. I have 50-55psi at 70mph on the highway and 30 at idle at operating temps. Its 60 cold and 40-45 cold idle. This is a stock 89k bottom end BTW.

What cooler do you run?

None.

Hmmm. Well I may not need a cooler if you aren't having issues with weather like that. Do you monitor your oil temp? If so, I imagine it stays within a normal range without a cooler?

I only have 4 aftermarket gauges in my car. 3 on an A-pillar and one in the hole in front of the shifter on a 6-spd car. I only have air fuel, boost, fuel pressure and tranny temp. I've never thought about an oil cooler, if I were to add anymore gauges I'd probably add a coolant gauge, as I have always had the impression if the oil pressure is within spec the temp should be fine and if you use a quality synthetic it should have enough protection which is why for boosted motors most all engine builders reccomend a 15-40 or 20-50 for any FI application especially a turbo where the oil is fed to the turbo to lubricate the bearings and seals.

I have an oil temp gauge on my Rig, its usually 10-20 degrees cooler than water temp. Honestly dont know why an oil and tranny cooler will help. IMO Unless you're towing a lot of weight then its a must.

I don't plan on towing anything with my 240 lol. So I guess I'll be ok. I'll just see what my oil temp gauge says. Anybody else with experience please chime in.

Does anybody with a turbo run an oil cooler and recommend it?

In for this as well. I have a cooler installed but haven't gotten the car running yet.

im planning on running a small one with my car. IMO its good insurance, i plan on putting it in the feed line for the turbo. Im planing a small cooler just because heat is the killler of fluids, when fluids die then hard parts die and hard parts cost **** tons of money.

but Im in houston, and the temperature highs have been high 90's low 100's for like 2 months......

a $5000+ turbo build and joe blow leaves out the $150 oil cooler?

Can you put a cooler in the same loop as the turbo? Wouldn't that lower the pressure in the feed line too much?

I had thought about running this block for my cooler.

Where in south ms? Fellow turbo ls1 south ms guy here

not at all, the thermal expansion of oil is very little, not to mention regardless of how much the oil contracts as it cools the oil pump is still shoving in more oil behind it. hence, the pressure is sustained.

plus, often times the feed provides far more oil than the turbo can actually use so the turbo itself is the choke point.

I dont think that will help much at all. Yes, you will cool down the oil a LITTLE bit (going through a -4 line isnt enough volume to cool sufficiently) but you will heat it up again as it goes through the turbo.

the way i have mine hooked up on my 350z uses it off the oil filter. so from the ls1 block 1 -10 line goes to the filter, then filter to cooler, then cooler back to block

I'm in Moss Point, Pascagoula area. I spend more time in Mobile though. You have the same handle on silviaV8 right? I am one_cam240ss over there.

So, having it before the turbo wouldn't help because the turbo would just heat it up again. But you can't have it after the turbo because then you would definitely have issues getting oil back to the pan.

Also, I have another question. How much will an oil cooler actually cool the oil? If I had a closed loop that was just for the oil cooler could I have it open all the time? Or is there a possibility I would cool the oil too much and never allow it to get to operating temp requiring me to run a thermostat with it?

Yep thats me ... Sorry to hijack your thread...

Only way you could have a cooler after the turbo is if you have a lot of return line, and something that's not gravity fed, ie a pump, rearmount turbo setup. The way I see it, oils hot already, and only getting hotter once it goes through the turbo, so why not cool it down. Its cheap insurance.
