looking to wire in the Oil Pressure & Temp into my PSI3 on 06 STI. Have the defi sensors ordered

rather than fit a sandwich plate to the oil filter housing, or running the braided extension from the existing pressure sender behind the alternator i was looking at using one of these which allows you to run both from one place:-

and then fitting it above cylinder 3 where you'd usually mount the oil temp. Basically just thinking it would be tidier in engine bay, plus be the shortest cable run into the dash

Anybody any experience of using similar? good, bad or ugly stories - just wondering is there enough space to fit it with Inlet, turbo outlet, IC, PCV all situated down in round there

Cheers

If yours has the breather balance pipework & pcv pipe you will not have enough room in cyl 3 area, your best bet & what i do is put oil temp in cyl 3 area bung, oil pressure where the oil switch is & if you want to keep the switch, put that in the rear of the l/h cylinder head by the heater coolent pipes, threads are the same as the bung in the head, this also is the farthest run from the oil pump & is a very good indicator of problems with oil pick up pipe etc.

Cheers just the kind off info i was after.

Just so there is no confusion, you are talking about relocating extising pressure switch to rear of l/h head in blank shown in this pic above his thumb?

Thats the r/h head, yes in the 1/8npt bungs, there is 2 per head at the rear, i use the top one, you can unpick the wire from the loom under the manifold & its the correct length to reach the switch, keeping it looking as OE as possible.

Great so its fitted to the head on passenger side if looking into bay - be lot easier access on that side

Another one other question, is there a reason you dont run the defi oil pressure from the blank on the rear of the head?

You will get a more stable reading from the main gallery, as thats what directly feeds your critical components, the heads are more restricted.

Why not just put the OE oil pressure switch where it does most good? On the shelf in your garage!

Then put the Defi OP sender where it came from and the OT sender in the bung above cylinder 3.

The OE sensor is very good at showing you how quickly it makes oil pressure, a lot better than gauges calibrating for the first 4 or 5 secs, you won't spot a cracked pick up pipe with electronic sensing gauges, you will with the switch, it won't save your engine with low oil pressure once running, unless you use a upgraded psi type.
