Hi,
I'm in there process of deleting the factory heat exchanger from a rb26 block. i want to use a greedy/trust oil filter relocation kit.
What i was thinking of doing was, installing a oil pressure relief valve in the block. As the oil pressure relief valve is in the standard heat exchanger.
Installing a rb30 oil filter stud and sitting the greddy/trust (grex) adapter on the block. Then running my lines to my remote oil filter location.
Will oil pressure relief work ? will the grex adapter seal on the block ?

Your method would work but say if the centre bolt gets loose you're going to be in a world of trouble.

I did this, seals 100%

JHH Racing oil block, has 2x 10AN outlets, 2x 1/8NPT for gauges and 1x M10 for the OEM oil temperature sensor.

Im putting a heat exchanger (oil to water) in a car that doesn't have one.

Just be wary of your oil temps, my old RB25/30 with only a oil to air cooler only ever got to 90°c after being up it for a while, that was without a thermostat, during daily driving my oil was never really at optimal temp, unless it was on the track. I ended up making a blanking plate for the front of the oil to air cooler for daily duties.

My STI had a oil to water and an oil to air cooler with a thermostat (although even with the thermostat closed it still flows some oil), it took at least twice as long for the oil to get to temp, during cold weather the oil could take up to 15 minutes to get to temp.

Have you worked out what size oil to air cooler you need to have the oil  in it's Goldilocks zone?

Disclaimer: you may be all over this, my point is I've spent a few years of finding out how not to have my oil temps running in a safe place, or, having to drive like a nanna for 15 minutes because my oil temp takes that long to warm up, from my experience the minimum oil temp of 90°c should be seen before the loud pedal gets a work out, unless you like replacing bearings that is, ......apparently...  ,,?????

GREX plates all have thermostats in them, so it's not that bad, I also run a 25 row Setrab oil cooler (overkill, was like $50 to get the larger one, so why not? LOL)

What you can do on cruise/idle areas of the map is run heaps of ignition advance to warm up the motor quicker. Many OEM cars do this to speed up warming up the coolant (do it within moderation).

Would definitely be in trouble if the center bolt came loose @Dose Pipe Sutututu

i didn't take what size oil to air cooler you need to have the oil  in it's Goldilocks zone in consideration  @mlr

How was your oil temps before?

same, fresh build, larger oil cooler (19 row to 25 row)

However in the past, oil would be about 85~100 on the street, and hard out at Wakefield on a 35 degree day would peak about 120 degrees after 6~8 hard out laps.

Seems like you have a good hold on your temps.

You got a big sump??

I am also curious about the pressure relief, considering the oil pump has a relief valve to control pressure what is the intended purpose of this one? Is it there to prevent the oil filter from being over pressured?

I would not be concerned with the centre bolt coming loose considering a correctly tightened oil filter does not come loose.

Before motor went kaboom, stock sump overfilled by 1L

Now, 7L ASR baffled sump because I am stupid and spent too much money on my R33 and should have just bought a fast stock car.

LOL, I resemble that

    • Possibly avoid using a Cometic one unless the deck/head surface are perfectly flat. I did have a look just then and forgiving gaskets such as Tomei or Nitto don't exist for the FJ20, however the Bar-Tek or Kameari ones look good and might do the trick.
    • Because pipe threads for pipe things. M threads for bolt things. Throw some teflon sealant onto it and dust your hands off knowing you did the right thing, instead of going twice around the block to achieve a result using the wrong things. Of course, all of these solutions are ignoring the fact that the minimum thread pitch we're talking about here is 1.25mm, with the 1/4" in NPT or BPS being out around 1.4mm. You will need to know that the boss you're tapping has enough thickness for at least a few threads. That's one of the reasons that 1/8" is commonly used - because the pitch is <1mm. And why would you look to use 1/4" NPT in a BSP country anyway? Ugh.
    • Just throwing around ideas, does it need to be in the compressor cover? Why not the hot side piping?
    • 1/8NPT drill size = 8.7mm. Since the hole got messed up by me, it’s probably around 9mm.    So 1/4” NPT would be next step. A drill size of around 11mm would be preferred there which is not way of my M12 (drill 10.5mm and tap M12 threads)
