Hi,

As some of you know, i have a 4agze from a mr2 that im putting into my ae101 and turboing.

Now, this moter has a feed, and a return, for an oil cooler on the block. My question is, is this controlled via a thermostat AT THE BLOCK END. What I plan to do (hopefully) is use this line to feed my turbo lines, and use it's return line to return the oil. (as the oil cooler was nicked before I got the car.

Any ideas?

If its anything link the oil cooler on my car it appears to have No form of control it mearly uses an out and in to pump oil out and back in, where you route it is your choice ( to a cooler mounted up the front i would assume )..

yeah no thermostat there, will have to put one in. i'm using those lines for my oil feed for the turbo and seems to be fine, run from the adapter out, oil filter, thermostat with cooler, and on the line back i have a t-peice for the oil feed.

have you got the other adaptor?

sweet, was hoping that was the case. Don't particularly want the engine to shut off the feed to my turbo when it feels like it

Umm, i have a pipe going out (that was hackedf off when i got it), and a pipe that just goes into the bottom of the sump. I assume the top one would pump it out, it seems to come from a plate around the base of the filter, and the bottom one would just be the return.

I don;t follow what you mean about the adapter?

Um, that does not sound right?

the pipe that comes out that was hacked off, where does it come from?

You cannot just run an oil feed from pressure thru the cooler and return to the sump as the pump does not flow enough to have some going thru the coller and some thru the engine???

Long time comming... But i have my block back now, so i can take pics. It appears that the pipe is just feed of a hole in the "sandwhich" plate between the block and the oil filter holder.

And the return is just a pipe feeding into the sump, so thats sweet.

See what i mean now?

I don't see how the motor will notice, if anything its going to have less flow through my turbo than the cooler, so the pump must have enough flow to do it..

Factory oil cooler setup for the 4age:
Sandwich plate bolts between block and oil filter.
In the sandwich plate is an oil pressure relief valve similar to the one in the oil pump. This oil pressure relief valve is set to a slightly lower pressure than the oil pressure relief valve in the oil pump.
This means that any excess oil bleeds out through the sandwich plate pipe through the oil cooler and back to the sump (instead of bleeding out from the oil pump pressure relief valve and directly back into the sump).
Not a full flow oil cooler system but simple and fairly effective.
Low risk of leaks as the oil flowing through the oil cooler and pipes/hoses is at low pressure.
No need for a thermostat.

Crap.....

I want to use that for my turbo... Hmm, i wonder if there is enough pressure there to do that...

Ethier that, or i could remove the valve part so that it is at full pressure (easy to do, i can see how to do that) and then run it to my turbo through a reducer so that there is not much flow (i.e., doesnt steal oil from the motor).

You would also want to check that the feed for your turbo comes from after the filter, not before.
unfiltered oil can't be too good for the turbo.

Ok, well, that idea is out..

Guess its t of the oil pressure sender.
