Yeah. I would just get oil monitoring in first, then consider what else you need (if anything).

Given that your oil is highly unlikely to overheat on the road, oil pressure monitoring is probably the priority of the two. The good news is that tapping into the oil gallery under/near the alternator is pretty easy.

Having said that, I like monitoring oil temp too - particularly as a good guide to when I can give the engine moderate or full right foot. Oil temp comes up a lot slower than water temp. If getting at the rear gallery plug near the turbo is too much of a PITA job with the engine in the car, you could potentially look at a plumbing T-piece off the front gallery so you can fit pressure and temp sensors. The temp sensor might read a bit cooler that way, but super-accuracy is probably less important than overall trend.

Also - I think some Liberties have a water-to-oil cooler directly above the oil filter (copper coloured assembly with coolant in/out). If yours has this there is already some coolant-based oil heating & cooling going on. I believe a different water pump assembly is also required for that one.

For reference (noting oil temp trends above), my forester does not have that water-to-oil cooler.

Just bought a new to me sleeved shortblock and i'm starting to stockpile engine parts for my build, ill figure this out on the old motor before I go and do it on my nice new one.

The wastegate on my stock turbo is basically gone at the moment so its coming out this weekend, guess this can be done as a "While I'm in there" special

If you have a new engine build in the works it will be a piece of p!ss to put the oil temp fitting on the rear gallery spot and the oil pressure fitting on the front gallery spot (ideally on an extension hose because oil pressure sensors live longer without vibration).

yeah, just want to figure it all out on the old one before I intentionally try and kill it.

Are they meant to be about 1-2cm off the block? didn't know that you can kill the sensors if theyre mounted to the block

Temp sensors are fine plugged straight in.

The accepted wisdom is that oil pressure sensors* last longer if remoted mounted. See the long braided hose I used in that DYI Oil Pressure Guide I linked in the first page. Do your own homework on it if you want. I just ran with what I had read on the topic.

(*as opposed to the pressure-based on/off switch under the alternator which is pretty robust)

Well... forgive me Club Liberty for I have sinned,

since my last post life has gotten a little crazy, for those who saw me on facebook I shot a Brembo through my rear passenger TBSTI wheel, Copped a defect, Bought another Lib, and bought a BRZ.

Brembos were fitted by a somewhat reputable shop that claimed they had done it before, didn't want to do my own brakes for this very reason and had nothing but problems with them since the install. They leaked from day dot and that should of been the indication to go and take it to someone else instead of taking it back time after time to get it fixed.

The defect is the real problem...
I was defected for having a wet oil pan, bald tyre (singular), and exhaust to comply (no name genome turbo back with questionable cat components. Fair enough it did have an oil leak, my lazy ass replaced the valve rocker covers and didn't do a good job cleaning it all up. The tyre had me really salty had a full sized spare in the car and offered to change it over but I received a Red Sticker defect for that and told that I am unable to change it. Yeah fair enough, pain in the ass but I can get a proper exhaust, clean my sump up, and buy new tyres right? unfortunately not. My defect has the wrong vin, right rego, wrong name and drivers license number, right time and date. Took it in to get it cleared and was told by every shop "Yeah I'm not touching that," fair enough so I got in contact with the cops asking how this can be fixed, they said the only way that they'll correct the issues with the defect is to attend the mechanics as they clear my defect and sign off on it, unsurprisingly no mechanic I talked to was interested in this option. Spoke with the RTA and they said I'm SOL only other option is to do a blue slip.

Contacted LECC, wrote a letter to complain about how botched the paperwork was and got no response. Hounded the local area commander only to be told that they're not required to reply to complaints and the defect is correct despite the wrong information recorded on the paperwork. Then received a letter in the mail asking for the number plates back and once I handed them in I was told that I have no leg to stand on as the rego was cancelled and It's not a police matter. Great

Bought a BRZ as I needed a car and the cop that defected me was my neighbour and I was growing tired of the marked HWP car sitting at the end of my street and I was getting pulled over near daily for RBT's. Threatened legal action and launched a new complaint for harassment and then overnight I was left alone by Highway Patrol, They'd take the car in front of me and the car behind me into RBT's but i'd be waved through and I haven't had a breath test since so go figure.

Seeing as my high KM auto shell needed a blue slip I bought a 250,XXX KM 2008 GTB 6MT as a donor shell and I am currently in the process of stripping my auto and transplanting everything over into the new manual shell. Went and bought a metric ton of aftermarket parts and opened fire with the parts cannon;

Suspension Fuel Air Everything else
    TBSTI Front Lower Control arms, TBSTI rear knuckles (No brembo adaptors :) )
    Tein Coilovers (With covers for the threads)
    Whiteline Front and rear sway bars (with end links)
    Nolathane bushings (all of them)
    Balljoints
    Radium Fuel rails
    AEM 340LPH fuel pump
    STI pink injectors
    Secondary Air pump Delete
    AVO 2948
    GFB Deceptor Pro 2
    Process West intercooler
    Pro Speed Racing Turbo inlet hose
    Invidia turbo back exhaust
    New Subframe
    New Brembo
    Pads, rotors, oil cooler
    KoyoRad
    STI radiator caps
    Folding Mirrors
    Exceedy HD Clutch
    New Tyres
    Number plate relocation kit
    Alpine Amp + speaker kit
    Sony AX4000
    Cobb short shifter
    blitzen interior
    sound deadening


Basically spent the past 6 months buying up everything I thought looked nice on facebook marketplace and this weekend hopefully I strip my auto lib apart and turn it into a rolling shell to send to scrap. Plan is to build for handling and I would like 250KW but I would be happy with whatever it puts down before I put a build motor in, I was going to just do Head Studs, Head Gaskets, and a full seal kit on my 408,901KM motor. The Manual Shell I bought was a Club lib member car, it has receipts for a tune so I'll have to see if I can find the basemap ROM for a 2008 GTB 6MT. Got the local glassy coming to pull out the quarter windows and the plan is to take everything out of it and fill it with old parts for the scrappy. Never got around to finishing the motor build, Pistons, block, heads, rods, and crank are still sitting in boxes in the garage looking at me funny. Hopefully I've got everything I need to make one nice lib out of two, fingers crossed the manual one passes a blue slip. Not to anyones surprise but the place that passed my auto and did my brembos has since lost the ability to do blue slips and roadworthys all together since. Updates to come, I will be stripping both cars down to the shells so any advice on what I should do "While I'm in there" will be taken, looking at a quick rack but not sure if my very injured bank account will be happy.
