Rezz, that looks like the greddy "big capacity" oil pan. I don't think they are that deep stock.

Yeah, I just realized... I`ll delete it.

I'm not sure with the Stagea's, but, here is my experience with converting from R32 GTR (looks similar to your picture) 4WD to RWD. I used an RB30E sump, and pickup.

Mind you, it wasn't a bolt on proposition like everyone makes it out to be. I found myself removing the rear part of the windage/baffle tray that bolts to the bottom of the crank girdle. I had to do this to clear the rear of the RB30E sump. I also had to cut part of the baffle in the RB30E sump, because the pickups are in a different spot. (more forward on the RB30E)

Also had to put a "bulge" in the side of this sump where the pickup comes off the block to clear it. There are two different bolt patterns on the bottom of the R32 RB26DETT block, the RB30E sump uses the inside ones.

If i were you, i'd be modifying the original 4WD sump. (removing the front diff and driveshaft section through the middle of it. Because the direction i took, removed ALOT of the baffling. Not good for oil control, as i have now learned.

Thanks for the pic MegaGTS4,

Nameless EJ6, how is this conversion going?

I'd be keen to find out how you went. We know that the RB20, RB25 & RB30 use the inside bolt pattern (the smaller ones) and from memory i had to drill out one of the holes in the sump near the front of the engine, as this actually took one of the larger bolts from the 4WD sump.

I'd still like to know if the pickup location on the block are the same between the 4WD engines and RWD engines on the RB20's and RB25's...

I know from experience that when i used an RB30 oil pickup and sump, i had to cut the baffle in the sump to allow the pickup to sit a little further forward. I also had to modify the sump to clear the pickup. (as you can see in the pic)

I'd still like to see the original sump modified, as i also removed the rear baffle off the main bearing cap to help the sump clear the bottom end.

Post a reply on how you are progressing.

Well the engine is sitting in my garage.. I haven't even started looking at it yet. I've been very busy this summer..

But in the next two months I will be doing this and I'll be posting it up with GOOD pictures and full text.

This whole project is coming together really slowly right now. I need to sell my civic before I get started really. The only thing I've done is bought an RB25det2 engine harness for it.. then the sump is next.

I will post up a picture of it with the sump removed though in the next two weeks so people can see it. :D

    • Well, it's taken me until the last week of 2024 to actually do something on the Skyline but I consider it a good head start to 2025's efforts! I managed to justify (to myself anyway...) my purchase of the lift table. It made taking the rear subframe out a lot easier than it would have been without anyway! Everything is out and stripped down ready for a clean then powdercoating.  She's pretty grubby under there but pretty good condition for a 38 year old Japanese tin bucket. 12 years of zero street time have obviously helped that... I need to decide which of the factory suspension arms I will keep and replace so I only get what I'm keeping powdercoated.  Baby steps but it's a start!  
    • Turbo gods, some assistance and recommendations please I'm looking into a turbo kit for my 2.5 from MX5 Mania >>>>> https://mx5mania.com.au/products/copy-of-mx-5-nc-2-5-litre-engine-conversion-turbo-2005-2013 Power wise I would like about 200kw atw, and of course dose noises, apparently if you keep a stock 2.5 under around 200kwatw the engine and drivetrain will not hate life even when ragging on it a bit Max RPM on the 2.5 is around 6500rpm The turbo MX5 use is something around the disco potato size as  packaging room for the turbo is pretty limited, which will, I believe, give me my power goals I want and not have the turbo either under, or oversized, but the rear housing bit is confusing  It comes with either a 0.64 or 0.86 From my understanding, which so far is based off googling, so make of that what you will 0.64: spools faster = good Makes more EGT heat on boost = bad Less topend power than 0.86 = I'm only looking for 200 atw so that point may be mute????, I don't know, hence my questions  0.86: Spools a "little" slower = how much slower??? remembering 6500 is my max rpm Makes less EGT heat = good Makes a little more power up top = again, power goals is only around 200 Also, this is a street car, so there will not really be any long track sessions, in saying this I would want it so it was happy with at least 3 hot laps at Wakefield Park if the need arises  I already have a fancy pants triple pass radiator, and a oil cooler with thermostat will be getting installed as well Thanks for any information or recommendations you have 👍, and of course, the comments about me wasting money on drive in drive out modifications, or any other snide remarks about my manhood for owning a MX5 🤣    
    • Tape some wool onto the vent then take it for a drive I did this to my reverse cowl and was instantly unhappy, as anything over about 60kph would have the wool enter the engine bay, thus just adding underbonnet pressure and stooging my coolant stack, it did let alot of heat out when stationary though, which really didn't help once the car was moving, with the reverse cowl you could watch the coolant temps cheap up the faster you went on the hwy, I assume it would be alot worse doing track day speed With the vented bonnet (just after the radiator and about 1/3 up the bonnet) on my old R33 the wool on the leading edge sat at about a 45° angle as air poured out of it From looking where your vents are, and their size, I believe you should be fine at speed and air should be evacuated from the engine bay, I think it will be a night and day difference when stuck in traffic though for removing the trapped heat, and not sitting there cooking when parked up after driving around... #convection  Post wool tuft pics and data for science  This beastie is one nice and unique rig, enjoy
