oil supply..

[knoxvillenismo]

Ok so my brother and I have been tossing about an idea for a turbo setup. I'm only asking for advice from QUALIFIED MINDS!!! I'm not saying "Unless you drive or build 600+ horsepower turbo cars then go somewhere!". Just saying, if you wanna throw in your 2 cents then please know what your talking about. So, here is the idea; a remote (standalone) oil setup for turbos.

The idea is to have an optimized oil setup (pump, filter, oil weight, oil temp, etc..) to maximize performance and turbo life, mainly on high horsepower , high dollar builds. so here are the key points we have thought up;

-optimum oil viscosity for the turbo.
- cooler oil temperatures.
-cleaner running turbos.
-no need to tap oil pans or filter plates/housing.
-more precision control over oil conditions.
-higher pressure when needed (high RPM, high HP).
-high capacity oil supply.

Now, with that said, I have never seen this done. I have seen similar ideas on remote or rear mount turbo setups but never have i seen a standalone oil supply for the turbocharger. The system would be composed of the following;

-electric oil pump. a few companies make these. (Mocal, Weldon, northern tool..)
-oil cooler. 8-16 row?
-high flow oil filter (Amsoil, Royal Purple, GReddy)
-high pressure lines.
-AN fittings
-custom remote oil reservoir
-accessories like oil pressure gauge, oil temp gauge, etc..

So, this seems like a good idea but i don't wanna roast a turbo doing this without some other opinions first. This is an idea of what the setup would work like.



So what are some ideas? opinions? Feel free to tell me I'm an idiot or that this has been done or whatever. I'm just looking for some feedback on this and hopefully some reassurance that this will work.

First of all its not a bad idea but there are hurdles you would have to overcome. First the oil filter should be right after the pump in case anything got thrown from the pump you wouldn't want that in your Turbo or cooler. The other thing is if oil is not at the right opperating temp the oil will not do its job (actually the additives) there are poor point dispersants, inhibitors , detergents, and friction modifier additives that will not protect the Turbo unless at the right temp. Maybe some sort of thermostat maybe? I just think with all the variables it would be easier to run a oil cooler and change your oil every 3,000 miles.

Well, i took temp in to consideration, and i feel as tho an oil temp gauge will be sufficient.

[compactfean]

An oil cooler will bring the temp down too low with just the Turbo heating the oil.

I had this thought, but i was reading through some other information and this has been done by another nissan site member. He has successfully done this on a rear mount turbo 350z. His setup consists of a 3 quart oil tank, Mocal oil pump, oil pressure gauge, oil temp gauge, and some ss braided lines.

pics of the oil setup are about 1/4th down the page.

So I just read that whole post and they have done everything except the cooler. Since it will be close to the engine. In your setup. Might work. On his rear mount with no cooler he was running at 145°. So I would say try it w/o a cooler...if its to hot than get a cooler.

Another issue would be that drain from turbo is gravity, currently no way to get oil from cooler to tank, would need to rework or add another pump. Also agree that it would be too cool if this is only for the turbo with a cooler.

[knoxvillenismo]

ok, so i have revised my design here. ~3 quart oil reservoir mounted low down in the engine bay (probably directly beneath the turbo) to support gravity fed draining. Originally trying this with no oil cooler but i am pretty sure ill need something small like a 4 row. Lines on the pressure side will be 6AN and the drain, 8AN.

so my question is, which oil pump would be best?

i think the 2nd one is a little wimpy whereas the first one is kinda over kill.

If you are going to do it, put fins on the resivior, should really be no need for a cooler just for the turbo.

I have a similar setup for my rear mount on my S13 except I have a cutout before my turbo in case the pump fails. That way I can uncap the exhaust and bypass the turbine housing. The pump was always my biggest fear of failure since I never wanted to get stranded or smoke my turbo trying to get home. After all the turbos I have done I have been most satisfied with a engine supplied setup with an inline filter and small oil cooler on the way to the turbo. It just gives me a peace of mind with the mechanical oil pump being the supply. It is a good setup for a rear mount setup though.

Another option for cooling your oil would be to use a steel line from the pump to filter and put a few loops in it for more surface area.

yes.
