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

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.

    • 2001 BE5D Subaru Legacy B4 RSK (3rd gen) EJ208 (pink injector) Twin Turbo 280PS 5-speed manual Full time 4WD "RSK" grade which means all of the above LQC option which means stock rear spoiler  I got it primarily to export to someone outside Japan who was interested. These BE5 Legacy B4 RSKs are going through a bit of a resurgence right know in Japan as they are one of the few cars from the "turbo, manual, RWD/4WD, 280hp gentleman's agreement era" cars that don't require stupid money to purchase. Which for some people might be a good opportunity to get as a base for restoration. If I can't find anyone to purchase it I will certainly be doing that myself over the long term. Why? Because it's properly fast in stock form, handles well enough for a GT sedan, there's still enough aftermarket and (if you can wait a while) genuine part support to make it a restoration candidate (<-- that will only get worse over time so it's a case of do it now or choose get a BL5 4th Gen). Mechanically it's fine, has only 89,200kms on the odometer. The problem with this car is that the body and exterior trims are weathered from at least the last 10 years being parked outdoors. I'm the 3rd owner, the first owner was the one that had it for 14 years and barely drove it, had a low-speed front impact (which didn't damage anything behind the radiator support) and got it fixed and sold it. The 2nd owner put most of the kms on it and parked it outside for the last 10 years, hence the door rubbers have seen better days but if you overlook those cosmetic details, it presents pretty nicely. There is some minor rust on the LH rear wheel arch which I'll have looked at too at some stage.  Also as you'd expect from a car this age, the clear top coat is gone, leaving a satin finish on the roof.  Mechanically it's fine (as you would expect from a car with less than 100K kms) but the steering does feel slightly vague around the centre position at higher speeds. So first on the list is to get the steering rack bushes looked at. There's also the Lock button on the remote which doesn't work, but the Open button does.... it means that the anti-theft system thinks it's always open? It seems like if you open the car and don't start the engine within 3 mins or so the anti-theft kicks in again without any beeps or signals. So if you got to start it after that, it won't. You have to push the open button again. That's how I understand it anyway. Just a small irritation but not a big problem to sort out. There's only one mod, the Wangan SPL muffler. Just a tad louder than stock. It's a really good mod for those who don't want to wake the neighbours but still want to hear a more prominent unequal length header EJ20 sound. Anyway I hope to get all those things done eventually, that is unless someone wanted to import it to their country from Japan (where I live). I'm open for negotiations as I really would like a Skyline... but this will definitely suffice in the meantime 🙂 *Disclaimer: This is how I picked it up from the dealer, minus the stuff on the back seat. I haven't cleaned the engine bay or done a thorough exterior clean, aside from spray painting the wipers. 
    • Wow, even with the Audi logo centre caps. I love OEM wheel mismatches. 
    • Welcome!  Can't go wrong with a Stag.
    • Looks good. Nice height.
    • Hey all, a little help from the Stagea hive mind plz.. I'm days away from buying either a 2002 Stagea 250tRS AR-X Four, premium leather, power seats and all the old switches etc that go with it, or a 2002 Stagea 250tRS VR-X Four AERO, pov pack, cloth seats etc, with coil overs, sports zorst, comes with original zorst and suspension and parts. (I think I've got the models right?) Both are VQ25DET, have 160000kms, both straight no rust both with $2000+ in recent servicing receipts, both ride on aftermarket 18" rims. The Aero has a replaced turbo as well. I like the cool factor of the Aero car but the AR-X has never been modified. Neither have been driven hardly at all in the last 5 years. Any thoughts on which one or does it come down to personal preference? davemoto
