I always come to this forum for answers and half the time it I figure it out on my own just typing it out and reading it over :glare:. So I was stuck on the last step on bleeding the return line to the tank in the trunk but I got it done. If this is a re-post sorry.

NOTE: You need Nissan ATF fluid for this application. Check step "4" first so you can have everything ready to go.

Step 1: Fill tank 30mm above MAX line. "tank is located in right rear of your trunk"

Step 2: Open air bleeder on oil pump. Crack open till there is no more air coming out and you get fluid dripping. "This air bleeder is located on the pump on top of the rear diff. Bleeder is on right side. Can’t miss it"

Step 3: After you tighten up that bleeder you go and turn the ign on. Don’t start the car just turn the key to ign.

Step 4: You need to unclip the air bleeder connector. " This is a white clip located under the dash on the right side behind your kick panel" Opposite side of your ECU" Might be a good idea to un screw your kick panel before you do any of these steps. When this connector is unplugged it puts the pump in (air bleeder mode) and the pump operates at a fixed hydro pressure to the transfer actuator"

Step 5: You now need to bleed the nipple on the rear of the trans just below the tail shaft and above the hydro line attached to the rear of the trans. You want to give it 1-second blerps. You can hear the pump actuate while doing this. Do this step until there is no more air coming out the nipple.

Step 6: Go back to the tank in the trunk to check the level of fluid. Fill to MAX is necessary or just above. Now to finish the bleeding process you need to go back into the car to the air bleeder connector. You want to plug it back in and then UN plug it and plug it back in. You want to repeat this process until the lower level fluid in the tank in your trunk has a 5mm max air gap between the lower and higher level fluid. I had to plug in and unplug my bleeder sensor about 20 times at least. If you want get a friend to check the rear level while you sit in the car unplugging the bleeder sensor that might be easier. I had to do this on my own :kiss:

If this doesn’t make any sense let me know and I can retype it for you guys :kiss: I’ve done a search on this info this week and also about a year ago on this forum and never came up with anything conclusive so now we got it.

This is the tank in your trunk. I didnt get any before pictures but this gives you an idea of the high and low level's of fluid and how it should look when your finished.

This is the bleeder on the pump above the diff. Its on the right side of the diff. Very easy to spot:

This is the bleeder on the trans. I used a clear hose so I could watch the air shoot out.

This is the air bleeder connector. The fsm tells you to make a switch but it is easy to plug in and un plug many times.

      Why am I hitting a power wall with my stroked RB25?

      Just a thought, how come you didn't use a 4D table? So you essentially run 2x fuel and 2x ignition tables, and the table/map switch is handled when there's enough WMI pressure detected. This is mine, but using the flex sensor as the 4th dimension, note the slider at the bottom. Between 0 to 70%, the timing is blended/interpolated , once it goes past 70% ethanol full send

      Hi guys, after dreaming of owning a JDM legend for 20 years, I got the chance to buy a 1995 R33 GTR.  I live in a small country called the Solomon Islands which is in the pacific. There is no performance car scene here, however 90% of vehicles here are 2nd hand Japanese imports so there is a handful of JDM sports cars here, tucked away.  3 Evo VI’s, 1 180sx turbo, 2 GTO’s, 1 R32 GTR and 2 R33 GTR’s.    Only 1 Evo and a 33 (mine) are active. I’m hoping to set up a club to get these cars back in the road.    I’d known of my GTR for 9 years and always dreamed of owning it. At the start of this year I found it sitting outside a workshop waiting for a respray. It was in pretty bad shape, although running and driving perfectly apart from a big exhaust leak and worn out bushings. My brother in law who is a huge GTR guy came over for a holiday and I took him to see it, he got into my ear and I bought the car 2 weeks later as is.   I’ve had a pretty bad problem with alcohol and weed since 2020 and I really wanted to quit. So I used this as my motivation. I quit everything cold turkey and have been investing all my spare time into restoring this car. It’s honestly been the best experience and has been such a positive impact on my life.  There is no market for these cars here, no parts and no mechanics that can work on them, so if you wanted to sell one it would be pretty impossible unless you found the right buyer. After a bit of negotiating with the previous owner (a good friend) I got the car for $15,000 AUD ($85,000 SBD) which is insane.  I’ve almost finished doing a refresh on the engine, new turbos, spark plugs and split fire coil packs. Also new gaskets and seals, This car had no leaks to begin with, but it’s due now being 30 years old. . Next I’ll be working on the suspension, all new bushings, ball joints, king pins and new coil overs.  Then it will be body work, it has really bad rust in the boot floor, I have purchased a rear beaver cut from my bro which will replace the rusted out one. The car is originally KL0, but was burnt orange when it landed here, then it was resprayed toxic green and then Bayside Blue. I’m probably going to get it redone in Bayside Blue.  I’m super grateful to be able to enjoy this car and couldn’t have done it without my bro Chris from OG-JDM. Looking forward to the future with this car and hoping to get it on the runway at the airport here 😂  cheers fellas

      Also, it is just about triangularity. The less angle, the easier it physically is to do. Think of the amount of slip you're getting, as how hard you need to push an object. More slip, equals pushing way harder. Then the ramp is how steep the hill is. The Accel is less slip, which means it takes less pushing (less slip) to get it to be able to push apart. However, the steeper sides on the decell means it will take a lot more pushing (slip) to get it up the ramp.

      It's the angle of the ramp from the vertical. You're measuring from the horizontal. To convert, take 90* minus your angle reference = Nismo Angle.

      I agree, thus 45 degree is the *max* force one could apply to it. This is similar to what I've seen in uh... simulations... which allow you to play with diff ramp angles. Anything higher (or lower) than 45 degree would produce less force as 45 is the max... triangley.  I would state the 1 way is 90 degree, at least this is how my brain and other ways of explaining it refer to it. 90 degree also effectively acted completely open. I realise Nismo refer to it not as 90 (or 89) but "1". So I'm not understanding the angle on which these angles are based.
