Hello,

I am installing a rb25det on a Nissan Patrol Y60 (You australians might know it as the GQ shorty)

It was the same bolting pattern as the rwd sump, my block is from a skyline GTS so its awd, it still has the RWD oil sump pattern.

The problem is the oil pickup, It seems to it oil sump, but there is another place for an oil pickup on the block but the hole is filled, can I just drill the a hole on the back and put the oil pickup there ?

The rd28 oil sump has the deposit on the back.

I need to modify both the oil pickup and the sump too, oil pickup it self hits the border of the sump, so I will need to widen it and get a bigger deposit for the line to pass.

I will recheck this part this weekend, but I would like to see if there is someone out there who did it diferently.

I had to modify the oil pickup on a RB25DET from a Stagea (ie AWD sump) to fit a 2WD sump. It meant cutting rotating and brazing the fitting to the correct location. Also required heating/tapping/massaging out the sump to clear the fitting.

Do you have an AWD sump and you are prepared to cut and weld to remove the diff it might be a better option? I have no idea what you are facing with a GQ with crossmembers etc

The AWD sump would be too much work to modify, also, f**k why are all the bolts acessible, you need to take the flywheel off to access the back bolts.

I think the best method is to modify the rd28 sump, enlarge it a bit on the oil pickup and add a bigger tank on the back. The AWD sump would be too much work as I need the oil reservoir to be on the back, for diff clearance and I do a lot of big uphills and inclinations.

      That cannot have been a fun set of drilling. The stock "baffle" looks identical to rb26, I just cut fuel cell foam to fit the full length under the baffle.

      I understand your sarcastic exasperation. But to be fair - the baffles do indeed fit OEM cam covers. They did omit to say that you need to do a bunch of stuff. But they do fit them.

      Got started on the modification to make these splash plates fit over the long weekend. First the surprisingly time consuming task of swapping all the cam cap bolts to Tomei cam cap studs. I did the method of removing one bolt at a time, applying loctite to the stud, double nutting to torque as the manual described. Then carefully unlocking the nuts without disrupting the torque of the stud (and going back to re-torque a few times when it slipped). Finally applying the nut and torquing to spec. Repeat x28 Next up I went about removing the stock cam cover baffle so I could ensure it was fully clean after drilling for stud clearance.  As the blind rivets holding the baffle on were domed I used a punch to mark the center then used 4mm drill bit to carefully drill out the rivet without going too far part the baffle. As seen in other thread here is what is inside the stock baffles I decided on M4x6mm bolts to bolt the baffle plate back on with. I used a 3.3mm drill bit with some tape to mark the depth at ~8mm. Next was to tap the threads using a cheap bunnings kit M4x0.7. With the baffle removed I also drilled out the spot welds holding in the baffle plate oil returns. Unsure whether this was the best option or if I should have cut holes in the Hypertune splash plates to allow the oil drains to still function... time will tell. I then removed the the Hypertune splash plates so I could rest the cam cover on top and use a dab of grease to mark where the studs impacted the oem cam cover baffle. The most obvious spot was on the hump from the stock mesh is held. Using this hole as an anchor I bolted the oem baffle plate back into the cam cover and lined up the Hypertune splash plate. Marked the rest of the holes for the studs and drill those out too. Total 32 holes drilled and 12 threads tapped on the passenger side cam cover alone for this bolt on part that totally clears all OEM cam covers.. Drivers side next as well as some E85 safe fuel foam to fill the space behind the behind cam cover baffle plates. oh and some lock nuts for the splash plates of course.
