I'm sure this has been asked but I searched and didn't see anything. I might have not worded it right.

Friend of mine was looking over the stuff i have so far for my turbo 420A build. Almost there. :hellyeah:

anyways he asked if i had thought about running an external oil tank and pump to feed the turbo VS running it through the cars oil system.

He said the advantages are you can run different oil. It's going to be cooler then the engine oil and you can change it more often with less cost.
Also your engine oil pressure and over all system isn't getting messed with.

Anyone done this or know why i haven't seen it done on a 420A DSM before?
Thanks

No... The titls was so confusing I almost didnt click it
 
Most likely because it is a lot less reliable and more expensive. You will need to rig up a pressure switch to monitor oil pressure. It sounds like its more a PITA than anything. You would have to mount the oil resivior low and near the turbo to maintain proper drainage. Unless you run two pumps.

Too much work IMO
 
I agree I never said it was a good idea just thought i would throw it out there see if anyone had ever seen it done.

I agree it would make for a pain in the butt oil setup.

Some parts would be nice but i don't think they outweigh the trouble involved
 
You should look around on some domestic forums like ls1tech or something. Those guys often run rear mount turbos and might have more experience with this.

They use a scavenge system to pump engine oil back to the pan, but i don't think anyone uses a standalone system.

Not practical or cost effective.

This is not a new idea or cost effective but I think its an awesome thing to do if you have the room/capability to make the system. Things like this have been around for a while. I've wanted to do it(I have had a bad turbo cost me an engine) but like it has been said, its not very easy and takes up a good bit of space. If you do decide to do it let us know and post pics.
 
The idea interests me but the cost might be too great.
If I do try it i'll take a lot of pictures. But i doubt i will.

If i do it i'm going to mount the tank on the lower front passenger side mounted on the opposite side in the same spot the SMIC sits. Be good for cooling.

If your going to do this (which I doubt too :p) I would suggest putting in a oil pressure guage also because you will have no way of seeing if your pressure drops. Also your reservoir needs to be big enough so it can hold enough oil for the lines and turbo and still have enough in the tank for the pump to push not to mention less oil means less heat distribution (oil temp guage needed?). Last an oil filter would probably be a good option too. You probably wont have the contaminants that the engine has but I still think there will be a few. Oh! Don't forget about a breather too for change in tank pressure... thus making the oil filter needed. One more thing, I wouldn't depend on the tank to cool itself unless it holds 3 quarts of oil because the oil will be circulated so fast it wont have a chance to cool on its own (oil radiator needed?). Not trying to be a downer but if you solve all these issues and make it compact and affordable, you will be my hero forever.

Edit: Sorry about stealing the pressure switch comment Travis... For some damn reason I don't even see your posts till after I've wrote my own. I think it's because you are avitarless.
 
Like I said and you said highly doubt i'll even try it. gives me a head ache just thinking about it.

Guessing if i do try it it will be after the car is turbo and running perfect. than try to think outside the box.

I agree a filter breather and pressure gauge are musts otherwise it's going to fail.
