Hello. I was thinking of a way to get an isolated oil supply for my turbo, in my RX.

 

I was thinking "I need a pump". So how about using the powersteering pump to pump oil into the turbo then through an oil cooler then back to the pump?

Why? It'd coke way faster than using the engine's oil. Besides, the PS pump is capable of way more pressure than the turbo needs, and can cause seal issues.

So, do you think adding an oil cooler would help? Would it draw too much pressure down from the engine's oil system?

oil cooler, electric oil pump, and an accu-sump system???

 

TOP MOUNT oil cooler!!!

 

 

 

in reality, i own stock in the oil companies and I want you to have to change 12 quarts every 3,000 miles

I couldn't read past the sarcasm. Was that a + or - for the oil cooler? I infer a -.

My apologies, no real sarcasm intended... Just a couple thoughts. How realistic would an electric oil pump BE? (seriously, I'm asking you.. I don't know) I know I've seen electric water pumps.. why not oil??

 

From there, I let my sense of humour, and the late hour get to me. Its not altogether an awful idea, though.. Does RAM engines or someone make a high performance oil pump??

 

The whole dry sump idea came from thinking about how to properly set up an independent turbo oiling system in the first place.. you would want a place for all the oil to drain down to while idling, before shutting the car off.. yout turbo would be lower than the power steering pump and its reservoir, so oil would stay in the turbo when you shut it off and would cause long-term coking problems, wouldn't it? So, I figured ideally if you were to use the power steering pump, adding a separate reservoir and some sort of dampening chamber could help lower the pressure generated by the pwoer steering pump.. OR you could just get a smaller pulley for the pump.

 

Honestly, I'm talking a little over my head here. If I am really just blowing so much hot air, I will politely shut up No harm, no foul, I'm just sayin..

EA81T's had oil coolers - no extra pumps required. You just need an adaptor that fits between the oil filter and the pump to facilitate a cooler. Do a search it's been discussed before - there's been a group buy in the past on the adaptors IIRC.

yep, I have an EA82 one (maybe the same as an EA81....).

well, 2nd generation RX-7s came with EXCELLENT little oil coolers on the front of them, and the junkyard people often overlook them.. not too "little", either.. IIRC, about 2"x8"x14-18"

You mean a bigger one. Smaller pulley would yield more RPMs at pump in relation to engine RPM. It would have to be quite abit larger I think.

Open mouth, insert foot. :-p

 

Thanks for correcting me Gloyale

Let me rework my original post a bit- A seperate oiling system for the turbo is a good idea, since you could maintain higher flow and pressure to both the turbo and engine bearings. There are multi-stage oil pumps available, they are usually used with dry sump oiling systems, and often belt driven. The problem is, lose the belt, lose lubrication, and belts tend to pitch at higher rpms.

If someone has an extra oil pump laying around, I'd like to see what kinds of mods you can make to the passages to increase oil flow. Also to see if a different higher-capacity filter could be fitted.
