So I’m new to this whole r32 thing and I’m sure this topic has been covered ten fold. Hours of research got me nowhere. But my situation is slightly different. I have a R32 GTS-t with an r33 rb25det swap. my issue is removing the hicas.. I have the R33 power steering pump that has one pressure line, yet I have that extra pressure line the R32 uses for the hicas pressure line that I’m trying to loop in to the power steering in order to maintain my power steering. I’ve deleted the Hicas pump from the frame rail, looped the cooler line and removed lines running all the way to the back. I’m just trying to now loop the second pressure line Into the power steering system.  Would it be easier just to find the RB20 Gtst power steering pump with two pressure line fittings or is there something I’m missing and it’s a simple fix?

as stated, super new to this please help!!!

Um.  What?

The HICAS pressure line is completely separate from the power steering.  When I did exactly what you're doing (but with a Neo), I simply removed everything to do with HICAS (the thing on the frame rail is a pair of solenoid valves, not a pump).  With everything HICAS removed, the power steering pump simply connects to the rack via the original line (adapted at the pump end owing to being a different pump) and the return from the rack goes where it always did.  That's it.

And don't loop the cooler.  Plumb it into the return line.  You need the cooler.

I followed a diy about looping the cooler line into the line that was removed from the hicas “solenoid” as you said.. following THAT line, it eventually ends at the second pressure line by the pump which I believed to have been for the hicas. Which again I don’t have a 2 line pump it’s a single line pump which I have connected to the other pressure line that goes to the rack. My issue is the line the diy says to connect to the cooler line only runs to the open pressure line I have no hole for.

For example. In the second picture below, The red dots are the line I’m talking about, the blue is what I tried to loop but tracing the red lines back from where I tried to loop it in it came to that second pressure line which I don’t have connected because my pump is a non hicas pump, it only has the one banjo for the one pressure line, as shown below in the first picture to the left.

It's not rocket surgery.  Work it out yourself.  The PS circuit is dead simple.  There are 3-4 things in it (depending whether you put the cooler into the return or not).  Just hook them up.  Following a DIY that does not work for your gear is a fool's errand.

      Before you blow your car up, have you checked you've made all the correct modifications to the wiring if you're still using the RB20DE loom?   Some things to look at: The pin used for the map sensor on the RB25DET, is the same pin used on the RB20DE for the Ring Gear Crankshaft Position Sensor, no idea what you've got it plugged into now. The turbo pressure control valve solenoid you're talking about on the RB25DET, the same pin is used for the Variable Air Intake Control Valve on the RB20DE.   The factory manual has the wiring pinouts in it for you to check everything. It also has the diagnostics process to read codes out. In addition, there's a great table that shows what sensors and what actuators not functioning will relate to which signals. And Nissan confirm the as everyone else has from experience, the Solenoid being disconnected won't cause a fuel cut. However, the turbo pressure sensor being missing / wrong, WILL cause a fuel cut. https://www.nicoclub.com/service-manual?fsm=Skyline%2FR34-Workshop-Manual-English.pdf

      I've been hunting info on the G Series II - this is best I have found so far(Link below). Still waiting on the G35-1150 comp map, kind of very keen   So how do we go about getting precision on that little table of yours ?   https://turbosbytm.com/sites/default/files/product/technical-info/Garrett-G-Series-II-Product_Flyer 25 30 35_1.pdf

      yeah I get ~0.6L per session into the catch can. very ethanoly. It ends up overflowing out the breather of the catch can on circuit days too even with a 2.3L capacity catch can and I only drain out ~0.6L max. So every session I have to come in and drain the catch can, which is a hassle. So this is me cracking the shits and doing everything I can without removing the motor (back of head sump drain/breather and oil restrictors off the table). plans short term are: full length splash plates remove oem cam cover baffle add foam and reinstall at -10 or -12 AN fittings to the side of the cam covers down to the sump (luckily I already have fittings in the sump) Yes the ~340,000km unopened motor is probably not helping things

      I'd use any fuel safe foam....mine went in 15 years and 15 rebuilds ago, still getting reused I'd have to say I don't understand swapping to studs to fit a particular baffle unless you are having a massive blowby issue, and even if you are addressing crankcase not head breathing is probably the next step.

      BTW, the reason I came in here to "update" this list was that the Garrett G Series II range have been released and I've updated the list with their flow details if you're curious to check how they fit with previous Garretts and other brands The G-Series II G35 990 looks like a banger...
