I know there are a few threads on this, but I am wondering if someone would be able to tell/show me the specific wires I need to tap into on a '92 SS.

(I know about the water cooling related to the turbo)

You can find an ECU Pinout sheet here: http://legacycentral.org/library/ECU_Landscape.htm
Hope that helps.

right on. thanks. I was hoping to just wire it all in under the dash though. Even a pic of someone's wiring would prolly be enough.

Still wondering about being able to wire it under the dash...

-or- anyone know if a harness is made?

That pinout is not correct for Turbos...

You don't really need a turbo timer on the SS. As long as you keep the coolant tank higher then the turbo, it keeps working even after you shut off the motor.

I understand how the system is designed to keep coolant ciculating for a bit after shutting off the car. While it gives me some piece of mind, There are also other, more convenience related reasons I would like one.

On a side note, I've got the tranny and rear diff/axles in. I'm waiting on some stubs/clips so I can have usable front axles.

Sweet!

Try this one:

It's from Vikash (electronics wizard), so it has to be right!

Link didn't work. Still, I don't think I am gonna hassle with splicing into ECU wires. I'm really looking for an under-steering wheel way to do it.

Cornell must have finally took his account down. Looks like I grabbed what I need just in time then.

Wow, they did take it down. That really really sucks.

Yup, you said it! If he still has the stuff saved, I can host it on my server.

Good luck getting a hold of him, he dropped of the face of the planet. He's working on some crazy shit at the Cleveland Medical Center and I think they keep him changed up in his lab.

Bummer...

Oh no.... He's like a god to me.. I installed my boost controller, turbo timer (ECU diagram) and FCD all based on his postings and i didn't even get a chance to thank him

Btw I'm also installing my turbo timer as well and I'm stuck at the first step. I'm not too sure which line is the Ignition line...sounds newb but i'll post up a picture soon.

But I did find a perfect spot for putting the turbo timer, the box hidden behind a plastic cover just above the hood release knob . A perfect fit for a black HKS turbo timer TYpe-1. and I'm trying to mod the plastic cover into something like the glove compartment where you can open and close easily. Does anyone has experience with plastic moldings?

random as hell i'm sorry.

so is that the same way with the legacy touring wagon?

because i was looking into a timer...

how does that work?

I'm pretty sure you have it. The way the system is designed is to keep coolant moving for a bit when the car is turned off. I'm not quite sure how it does it, but I think it involves the natural build of pressure in specific areas along the coolant track that are hotter than others, thus moving the coolant from hot/high pressure areas to colder/lower pressure areas.

This coolant movement is supposed cool the turbo and in turn the turbo's oil so that it does not have time to coke. This is how I understand it, but I could be wrong, totally wrong.

but would our turbo'd cars come with them stock?

i dont think mine has one because there is no running when i shut the car off..

The car turns off....the coolant heats up and rises to the highest point, ie the reservoir, as it rises to the reservoir it pushes the colder coolant, currently in the reservoir, down the line into the turbo. This cycle continues until everything reaches a neutral temp. In theory this is actually a much more efficient way to cool things after shut off as the engine no longer is running and the car can achieve even colder temps than running at idle.

The cars do not come with turbo timers stock. The after-off coolant flow is 'stock' in that it is designed into the system. It's not an additional part per se, just the way it is designed.

I would typically try to set the timer to turn the car off about 5-15 seconds after the radiator fans go off. That is generally when the oil and coolant are comparatively are at the best temps.

My issue with relying solely on the after-off coolant flow desgin is that the oil still sits. The coolant moves and helps to cool it quicker, but the oil still sits. That being said, I don't think I've heared of many coked stock Subaru turbos, so it sounds like it works.

link still works for me....
