STS - separate turbo oil system Qs
STS - separate turbo oil system Qs I am planning on setting something up in my trunk to have a separate oil system to pump the oil to the turbo and back.
I don't want the engine involved at all.
Any suggestions on a tank that would be a good option for this? Or a good DIY tank? I haven't seen any systems this way from my searching.
Thanks.

You could probably get a tank for a dry sump engine to work well aka LS7. Then just add an oil cooler under the car with good airflow and an oil pump. Make sure to put some sort of alarm or indicating device to let you know your pump is doing ok. I would also suggest running a temp gauge in the supply line to the turbo to ensure the cooler you choose is doing an adequate job. You could also run the pump on a timer upon shutdown to circulate oil through the turbo for cooldown.
I really like your idea. On my STS Avalanche I broke the supply line to the turbo going over some whoops in the dunes and it puked out 4 quarts of oil in about 30 secs. Almost killed my engine that day. My buddy asked me what all the smoke was coming out the back of the truck and luckily I shut it down in time.

I too like this idea and have been reading up on oiling systems for turbos. Not trying to hijack but here is a picture of a set up that I was thinking of.
I have the pump pulling the oil through the turbo and having gravity getting oil to it. My question is, will this enough or will another pump need to be added to push the oil. I am by no means a turbo guru but my thought process is people having oil go through the seals, so with this setup the pressure won't blow through the seals but rather keep it from doing just that by having the sucking effect.
Any thoughts, opinions, or concerns. Like I said before sorry for the hijack but I think we could both benefit from this, thanks

So if it doesn't heat up quick enough... 
What about having the cooler under the rear of the car where it won't get much air to start off with and when it gets to a temp that is getting hot have the fan turn on to regulate the temp? I've seen some websites with a fan on the cooler. Could that solve that problem or is there more to it?

Could that solve that problem or is there more to it? i really have no idea, when i was first starting to make a rear mount turbo setup i asked the same question and someone was saying that it would be a prob. in the end, i ended up just running a return pump, just much simpler and less stuff/ weight.

I thought about this before and think it will really complicate things. Depending on how much the pump flows you may need to regulate it, you will also need a return pump, cooler, and resevor. I would not think it would need to be heated..could be wrong.

^^^^ Thanks
I really want to avoid messing with the engine oil, drilling, tapping and all that jazz. I guess that's just me being difficult
. I can handle this setup being complicated as long as it's feesable. I don't like the fact of having all your eggs in one basket, but that's just me. Keep the comments coming.
Hey sujomatt you getting this, good stuff here.

glad to see your looking into this option matt! your half way there with one pump already. the return pump you have is basically just a bildge (sp?) pump anyway. your going to have to mess around with it to get it running right. the thing that stopped me was I couldn't figure out how I would increase the pressure as the turbo spooled up. that for me was the only thing that stopped me.
the extra pump was like 200 buck,then some sort of tank 1-150, fittings, hoses 200 MAX. oil temp gauge is like 50 bucks. it's not really that bad, if you can figure out how to increase/decrease flow with rpm/turbo spooling.
just remember everyone said a turbo instead of a muffler, was stupid.sure "it'll work, but wont make good power,to much lag" ect. now theres guys with 100+mm rear mounts

One thing I always never liked about turbo set-ups was using the engine oil for the turbo(s). I never liked how the turbos heated the engine oil up so much and always never liked the idea of all the lines running everywhere. If one breaks down, you lose the turbo(s) AND the engine. Good idea!

Wouldn't you need two pumps? Cause the oil feed line on most STS system is pressureized for the oil filter adapter, then as it would go threw the turbo it would go to the the cooler to be cooled then a nother pump to push the oil back up into the holding tank in the trunk. I just don't see the oil defeating the laws of gravity. Depending on what size oil container you want to run just get alumiumn box made that fit in the cubby hole or in the spare tire hole drill threw the body and down to the turbo. I would like other said put some type of signal light/sound to let you know the pump is working. I would also find a way to put a oil level sensor in your oil contianer.

I wonder if the pump would be powerful enough if it could actually suck air/exhaust throught the seal, if it can pump oil out. Hmm... Just brainstorming.
I think I read somewhere that the STS pump is throttle sensitive by the way it is wired? So if I where to hook up both pumps via the same way that STS wires theirs, that could solve the problem with matching the pump with the rpms.
Good stuff, keep it coming. Thanks
pump I made a engine belt driven scavanging pump system some years back for my incon tt because i didnt trust the electric pumps myself . But was very costly to make and only made about 10 or so kits that are still running perfectly as far as i know and even made a vac version for another guy on here last year that i saw for sale this month !!Its a really nice setup .Actually,if its stiill for sale, you would just have to sell his vac pump and replace with a scavanging one !A couple of guys were intrested just in his pump ,,so you might luck out if this were something you might be intrested in

Does anyone have an oil pressure guage at the turbo? Well, not "at" the turbo but you know? Would this be a good idea to monitor the pumps as another option for the buzzer. If so what does it read?
