That's what happens to mine when the O2 sensors are old or fouled. If you'd rather see it bounce between 14.4-15.0 replace the front O2 sensor.
Oh btw, once you richen up the tune you'll be buying front O2 sensors annually. Mine last between 6-12 months.

Well, I know I said I was going to wait a few weeks before ordering oiling stuff...but, I lied. I'm sure I've probably missed something or will need to order more. This was by far the most exhausting/research heavy part of the project so far. So many types of fittings and connections needed, and the distance it has to go adds more to it.
All said, with taxes and shipping it ran ~350, which brings my project total to 1050. I think with the intake/charge piping and spark plugs still to get, I will easily be around 1200 on the project total.
Adapter to thread in to the block where the oil pressure sensor is that will allow me to run the sensor still.

I measured it out, and i'll need ~10/11 foot of feed line to get all the way back to the turbo. Longest I could find by itself was 72". I reached out to a tuner place that made custom feed lines, and they could make a 11' one, but it was going to cost over 100 bucks. I'm sure I could have probably gone to a local hydraulic supply company and had one made, but, I didn't want to spend the time driving around asking questions and getting cost and all.

Aside from heat (which is an issue pre-turbo), the actual reason to avoid pre-turbo wide-band O2 sensors is accuracy. The AF ratio sensing is all relative to atmospheric pressure, and if there is any significant pressure on the exhaust side of the sensor, it will read incorrectly.

The oil leaks past the oil seals after engine shutdown - a turbo timer won't help with low-mount turbo oil issues exactly...
My turbo timer is annoying when I'm late getting to work or an appointment. But at least it is there for a reason.

I need this to be finished. It'll be a beast. Face out the window feeling the wind in my hair then im full face stretch. Nice change up to the norm SC build. You got my wheels turning...
I just started working on a forester STI project... I'm about the turbo life
Post pics for me!

Does anyone running one of these setups have concern with drawing oil volume off the engine at the pressure sensor?
It seems these things idle at about 4psi.

Might be in a position to get all the oiling stuff installed this weekend (got the bike and mr2 running good for now), and I want to get some other opinions on what I’m planning for the turbo timer. I emailed Greddy’s tech support, and their response was “we’ve never used it in an application like that, here’s a link to our manual”, so that was worthless.
It’s a Greddy Full Auto Timer, which has all sorts of functionality I’ll never use. Looking at the first picture I’m thinking it would be safe to assume I don’t need to be concerned with hooking up the parking/speed harness since I will never use it like Greddy intended (yet their tech couldn’t answer me if the unit will still function without those wires being connected).
Looking at the second picture, here is my thought process/assumptions.
12v -> red, should be to any 12v constant power, this is what will keep the pump running once the motor is off.
Blue -> ACC, should be anything that has power when the key is in the ACC position but not when the key is removed. My assumption here is that this is how the unit knows that you’ve turned the motor off and how to start the countdown timer to kill power to the pump.
Green -> to pump?
Black -> ground

What I’ve read before is that folks end up adding ~quart to compensate for the extra oil being diverted. I have an aftermarket oil pressure gauge though and once the motor gets good and warm I run between 15 and 20 psi. Something I plan to keep an eye on.

I have zero experience with Greddy brand turbo timer, but a couple I have done definitely required the park/neutral wire to function. I assume it has a built in fail safe so you don't turn the key off in drive and it keep the engine running.

That should be easy enough to tap in to, should just be able to tap in to the switch for the e-brake (I assume).
Any reason for the speed one that you can see?

The ones I dealt with were only a park/neutral signal. Do they want a park/neutral signal AND a speed signal, or is it a one or the other kind of thing?

Good idea to keep the scavenge pump on for a while after the motor is off.
I like having the parking wire hooked up. You'll probably want to set it to 30s or something and that's it. But you can always release and reset the parking brake to turn off the pump. You can leave the speedo connection open/disconnected with no problem - if connected it can display your speed digitally if you want...
I think you are going to want to use a relay to power the pump, with the coil triggered by both the ignition power and turbo timer output, but diode isolated.
I can't remember what triggers the turbo timer to start its countdown. I know for sure that my old-school HKS turbo timer starts its countdown even when I just switch to ACC mode.
You are probably going to want to do this process in stages. You know you need to hook up constant power, ground, etc. From there, you can experiment what it does with power applied to various wires...

It has two wires. When I was reading through the manual for it, you can apparently set it to alarm if you’re above certain speeds and stuff

It would make sense for it to use the ACC as a trigger. I’m assuming that I can hook that wire up to anything that doesn’t have constant power but does when the key is in ACC (I.e. cigarette lighter).
I’m think you’re probably right, just hoping to narrow down the amount of experimenting/frustration of connecting and disconnecting wires.
