Not really, simple process. Always start with the rear left caliper as its the furthest from the brake master.

Grab a clean bottle of brake fluid ( empty if possible ), if you can't get an empty brake fluid bottle grab any clean bottle about the same size and fill it with brake fluid about 1/3 full. Next grab a hose that you can squeeze over the caliper nipple making sure it seals over it properly and is long enough to go to the bottom of the bottle when the car is jacked up and the bottle sitting on the floor.

Jack the jar up, take the wheel off, open the nipple up fully and squeeze the hose onto the nipple and stick the other end in the bottle making sure the hose is inside the brake fluid.

Take the lid off the brake master and pump the pedal until ALMOST all the fluid is gone dont let it go dry, pour in the new fluid into the brake master until its almost overflowing, empty the bottle of old fluid you have sitting on the floor at the wheel and pour some new fluid into there and make sure you place the hose back into the bottle again making sure its inside the fluid. Then you pump the brake pedal SLOWLY 5 or 6 times and that will make sure all the old fluid is out and there is no air in that line.

MAKE SURE YOU CLOSE THE CALIPER NIPPLE COMPLETLEY OFF before you remove the hose from the nipple, once closed remove hose and that caliper is done.

Check the brake master and fill to full line if necessary.

Go to the next caliper, now you place the 10mm ring spanner over the nipple first, then squeeze the hose over the nipple and again place into the bottle of fluid, open the nipple pump 5 or 6 times slowly, always make sure the hose is going down to the bottle and the bottle is LOWER than the caliper, close the nipple off BEFORE you remove the hose and move on to next caliper repeating process.

Easy peasy

The best way to bleed the whole system is with the help of a friend or a little ingenuity.

Do exactly as Mungy suggests but as an additional step, once you've closed the bleed nipple again, pump the brake until the pedal is super firm. Get someone to hold down the pedal (or jam something between the seat and the pedal so there is very firm pressure onto the pedal) then reopen the drain nipple to release the pressure in the line and close it again whilst still being held down. This often forces any extra air out of the line and draws a fresh supply from the reservoir.

After you've finished pumping the pedal always close the bleed nipple whilst the pedal is held to the floor. This makes the system always draw from the reservoir rather than back from the bottle.

Yes that is the way to do it when you have someone available, however working in a dealership a while back we were always working on cars alone, the way I described is faster and can be done with one person only

      Boost cut after swap(RB25DET NEO) R34

      Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.

      So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here

      V37 Radiator removal

      So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.

      Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go

      OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.
