Im new at this I always just research or figure out things on my own, but i tried and I i'm lost. Im working on a 04 evo I installed a PF2 green turbo so my feed line is connected to the bottom bolt off the filter adapter. My question is; would i be OK installing my pressure sender off the top bolt or is there any other way?
please any ideas would help. thank you guys.

 

I believe there is the t fitting that will utilize the oil feed and the oil pressure, or the sandwitch adapter will work. Hopefully my question gets answered

 

Soo what is the best way to hook up the oil pressure sending unit. should i get this http://www.amsperformance.com/cart/A...Unit-Line.html and mount it on the firewall? thats what i kinda read from here being the best way.. Will that be all i need if i get that ?

 

Anyone know if you can get away without having to drain all the oil?

How much will you lose if you drop the filter and the two sending unit plugs?

 

Not much. Maybe 300ml. I had to pull out the filter when unbolting the control arms to give me space. Didn't take much to top it back up. Assuming the car is off and all the oil had a chance to drain back to the pan.

 

Good to know, wish I had known this yesterday when I dropped my LCAs...

Oh well, live and learn.

 

I have hooked the pressure sensor on the block in place of the factory oil sensor and moved the factory one to the side of the head (removing the existing screw, the same as on the oil filter housing).
That's much more important place to monitor the pressure.

At idle I would recommend to keep around 30psi. 20 is way too low.

The best place for sensing a temperature would be oil pan (needs a welded nut for bolting a sensor).

 

^ got a picture of where this screw is on the head?

..finally got some pics

here is the place where I moved a factory oil pressure sender:



aftermarket sender installed in place of the factory one:



I had one additional pressure sensor with gauge laying around, so decided to hook it up to the head (note I have SAS disabled, it's valve, tubing and the mounting plate removed):



balance shafts are removed, bearings rotated and oil pressure reduced with an additional washer over the pressure regulating valve.
Oil: motul 300V 15w50
Pressure at idle (engine at operating temperature) -
Block: 1.9-2.0 bar (27-29 psi)
Head: 1.3-1.4 bar (19-20 psi)

 

what thread is in the head? 1/8 npt or bsp?

 

it's 1/8 npt, senders thread straight in..

..i was mistaken regarding the oil filter housing thread size in previous post, which is 3/8 bspt

 

Very nice!

How did you manage to tap the head without getting shavings in your oil? I assume you did this without the head on the car?

 

threads are already in there, factory machined, just tapped with allen screws..
there are 4 screws on the head if i'm not mistaken.



you can actually install a factory sender with no modification.
For an aftermarket sensor you need either SAS (EGR) and its components removed or a suitable extension piping installed.

 

this thread rocks!! realy helped a lot guys thanks again!!!

 

Ive got the aem analog oil pressure sensor and just replaced the factory oil pressure sensor(dummy light) and it works fine no worries
