Rb26 Engine Into R33 Gts-t Shell, Sump Questions

I am putting an RB26 engine into my R33 GTS-t shell. I have a 4WD RB26 sump, with a Trust sump extension on it, and all the front diff casting cut off, and the drive shaft holes welded up. (I'll try and post a pic of it). When I compare it to the stock RB25 pressed steel sump pan the RB26 one looks deeper where it would sit atop the X-Member. I am not sure if it will even go in the R33 GTS-t shell with it on. To save me messing about trying a scrap block with this RB26 sump on in the rolling chassis, has anyone tried this? If it won't fit waht are my options for sump that will fit the RB26 block and the R33 GTS-t shell, and what oil pick up can you use? Ideally something baffled for track usage. Thanks.

Agree, you've already removed all the material where mine ran into the steering rack (pictured). I'd be dumy fitting it to the motor and slotting it in minus goo and box first though.

I always thought the xmembers and engine mounts were the same across the board, even with the gtr/gts4 and non 4wd models, probably wrong there though, but if not wrong then it should have enough clearance but not sure about fouling on anything else (see above ^^)

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      Thanks for the quick reply. To be clear, when you say turbo shuffle do you mean turbo flutter "stustustu" or referring to something else? I had thought they were the same thing. When I wrote the post my intention was to say it wasn't a flutter/compression surge sound. My understanding was that a flutter sound would be occurring when throttle is released, whereas I can keep the throttle in the same position for this noise

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      Hi everyone, I've been wrestling with this for a while now and have been trying to find out the cause. For context, the turbos used are Garrett 2860 -5s, the BOV is a BNR32 HKS SSQV IV kit, the car is currently tuned to ~470 whp on 17.5 psi. The car drives normally, pulls well when it doesn't happen, and I can replicate it fairly easily. It does not sound like turbo shuffle or flutter. The engine has only a thousand or so miles and has had this behavior since it was completed. After my engine was built for my R32 GTR, I noticed that the car now sometimes makes an air discharge sound on what appears to be positive boost pressure that sounds really similar to a BOV. I had thought that it was a BOV issue but even when replacing it with a brand new unit, the sound persisted. It seems like it's coming from the passenger side but I may be mistaken. The closest scenario I could find was this post here https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/https://www.gtr.co.uk/threads/maybe-a-boost-leak-opinions.147955/ started by @yakshii and it sounds very similar. As in, at partial throttle once I reach positive boost I begin to hear the same psh psh psh psh psh sound like air is leaking somewhere when I keep the throttle in the same position. It most commonly happens in 4th gear at around 3-3.5k RPM and 5th gear around 2.5-3k RPM, which seems to coincide with normal positive boost thresholds. It might be similar to what @Austrian GTR mentioned about his own HKS SSQV. Notable difference would be that when he applies more throttle when it happens, it stops. In my scenario if I apply more throttle during this repeated psh psh psh sound, the cadence of the sound gets faster and louder rather than stopping. If I lift off slightly and apply throttle again, it will normally stop and pull without issue. I've checked all rubber couplers to ensure that they are tight, but have not gotten the opportunity to properly do a pressurized boost leak test. If anyone has had similar experiences or thoughts on what might be the cause, I'd be very keen to hear them. I also have a video of it happening from inside the cabin, if that would make it easier to understand: https://youtu.be/2zqZXcx8jbA
