got advised when ordering the restrictors today from highoctane that they wouldnt run them in a 25det vct head

I told them how most of you guys are blocking off the rear feed and running one only up the front

and that my plan was just to run one in each however they still didn't like the idea

I'd really like to hear from anyone who's had them fitted for over 12mths with no dramas

Im fairly sure I'll have no drama's as a mates rb20 does three laps and fills his 600ml catch can over and over again

so seems like theres plenty of flow in the rb's

just because he is a mechanic, dont assume he knows everything.

past experience is worth 100x more then a educated guess.

keep that in the back of your mind and you will be fine.

If anything dosent look right, post it up on here and someone will help you thru.

when your putting your motor together and your keen to get it going,

dont guess / rush on something your not sure of, cause it could cost you dearly in the long run.

      I picked up an open Center with shafts. I was told the Open shafts will fit a mechanical LSD and looking at them. I think they will work. Will update

      The manual says a lot about the different ratios requiring different shafts. all the Centers are the same but depending on the ratio, this determines the shafts because different ratios need the center to be offset more or less or right to left.

      those 2 sets of shafts will not interchange and if you’re lucky you haven’t damaged anything with all your pressing and bashing you said you’ve done

      Lets play a game - What is causing my oil consumption?

      By TurboTapin · Posted

      Freshly built stroked RB25/28. Motor runs great but consumes a lot more oil then It should. This summer with the heat I was consuming roughly a quart per 1800-2000kms. Now with the cold weather coming in, I'm consuming a quart per 1000kms which is no bueno. I had originally chalked this out to break in taking a little longer then it should, but I'm now around 4000km's on this engine. I think it's fair to say something isn't quite right. Here's the kicker, can't find what's causing it. I've also spoken to my engine builder and Precision Turbo and can't figure it out. Here's my train of thought on possible causes and what I've done.  Precision Turbo - I originally started thinking my oil pressure might be a tad too high for my 6466 Gen2. I took the center cartridge out, and while yes there's signs of oil on the turbine heatshield, it's very moderate. There's also very minor in/out play that concerns me. I sent pictures and videos to precision and they said the residue and in/out play is minimal and they doubt this is the issue. For piece of mind, I went ahead and installed a Turbosmart OPR V2 to bring oil pressure down. Made no difference. Precision is willing to take it in on RMA for an inspection and I'll probably take them up on that offer for peace of mind. BTW. Is it just me or does the turbines inducer's look clipped and not even between each other? I just noticed this now while posting and looking at the picture zoomed in. Might just be the picture...  Rings - Hot compression test and leak down test look good. Compression is 160 +-2psi across the board. I leak down at 16% on cyl 1,2,3,5,6 and 18% on cyl4. Keep in mind I have a snap on leak down tester and they read high (I.E, 15% on my wifes 2018 Sentra with 70000kms). Sparkplugs show minimal oil (Only #4 seems to have a tad). At a quart per 1000km's though, I would be expecting them to be wet. Here's the kicker, I run WMI. I'm thinking what if my compression rings are great, but I have an oil control ring issue on cyl4 and my WMI is steam cleaning the pistons and sparkplugs? I can still see the "Spool" logo on top of my CP pistons. The only time I see smoke out of the exhaust is in the high rpm/load range. So far, this is my main culprit. I'll probably turn off my WMI and go out with the car at spring pressure tomorrow and repull the plugs. Other thing that's strange though is that I have never seen any oil in my catch can. Thing is still dry after 4000kms. Cyl1 - Left, Cyl6 - Right. Valve seals - They're new and I would expect oil consumption on idle, first cold start or during decel. None of which is happening.  Crankcase pressure - I have 2x 10an valve cover lines to a vented catch can. Head drain and opened up internal oil drain paths. I also don't run E85. I've never seen any oil in my catch can. Doubtful this is causing any issues.  Rear main seal - I have no visible leaks, but figured maybe it was my rear main seal. After now having added 2-3 quarts, I would expect oil to leak out the bottom drain channel and/or my clutch to be slipping.  Let me know your thoughts. With winter coming and taking the car off the road until spring, I'm fine with pulling the motor apart but I would hate to take it all apart and the turbo was the issue in the end.

      Actually, the best option is probably to get some of the stronger aftermarket driveshafts that have both the 5x1 and 3x2 pattern on them, so OP can do whatever the hell OP likes with the diff in the future and not have all this angst. I posted a link to them sometime in the last 2 weeks, I'm sure.
