Greddy Oil filter relocation kit and Oil cooler Install

[Tom24GR]

Hello everyone, 

I am working on a 1993 R32 GTR for a friend of mine and have to install a Greddy oil filter relocation kit and a Greddy Oil Cooler. The oil filter relocation kit comes with two plates (one that goes where the original oil filter went on the block and one where the oil filter will eventually sit [somewhere near the dirver's side strut mount]). The oil cooler comes with a thermostatic sandwich plate which also seems to go where the original oil filter position was. However, it also mounts up to the plate from the filter relocation kit. 

Do I just hook up both kits as normal and simply screw in the thermostatic plate on the oil filter relocation plate and then the oil filter on top of that? Or do I put the thermostatic sandwich plate on the block (and attach the oil relocation plate on top)

I have included a picture of the 3 plates in question. The plate on the left is the plate where the oil filter will go after being relocated, the middle on is the thermostatic plate that came with the oil cooler, and the plate on the right is the plate that screws into the block where the original oil filter location is. The second picture is just me test installing it to show my idea. 

I was wondering how I should route this and needed input from anyone who has done this. I.e. How to arrange the plates and which tubes to go to which ports. 

P.S. I didnt order these parts or plan this out I'm just the one installing them. 

Thanks in advance!

You need to make sure the oil is filtered, whether or not the thermostat is opened. Can't really tell how it works from those pics and I assume there were no instructions provided....

Did the kit come with lines, or are you making them. The old school location of upside down on the strut tower is a crap idea. Much better to mount the filter upside down on the chassis rail in front of the front diff

BTW, what you have is different to every Greddy kit I've seen before, they normally have the thermostat built into the relocated mount, are you sure its genuine

[Tom24GR]

Yes I'm sure its genuine. I believe the mistake my friend made was ordering a relocation kit separate from the oil cooler kit rather than getting the combined kit. I saw on Greddy's website these are 2 separate kits.

The kits came with lines. 2 lines on the relocation and 2 kits on the oil cooler. 

Looking at this now I believe that the oil will be filtered whether or not the thermostat is open. 

The first picture shows how the plate operates when cold. Oil comes up from the bottom and goes into the filter- and exits the filter back to the block. (when cold it comes through where the spring is in the hole).

The second picture shows how it will work when it is hot. The thermostat opens and the oil flows out of the thermostat plate to the cooler- it then comes back to the filter by the space that is now opened because the thermostat is open (and returns to the block). [Where the brass piece is now- as its at room temp its closed]. 

The third picture is the bottom of the thermostatic plate. 

In other words, when the thermostat opens the part of the plate that would lead directly to the filter is closed but there is enough space left open for the oil to go directly to the cooler. Additionally the space that is now open because the thermostat is open allows oil to flow back from the cooler into the filter (through the left port). 

The truth is they should have gotten the combined kit but probably did not realize they can achieve the relocation and oil cooler with one kit rather than 2.

What do you think?

P.S. The oil filter will go near the strut but it won't be upside down- it will be vertical.

Adding the P.S.

I have just tested the thermostatic plate in boiling water and can confirm that when hot the hole that leads directly to the filter (without going to the cooler) closes and the return passage from the cooler opens.

I have a greddy kit as well, one with only dash fittings tho. Can upload the instruction manual somewhere if you want. That includes instructions where to hook up what.
