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.

      Front LSD Quaife , how streetable ?- QDF3L Owners

      By joshuaho96 · Posted

      Major thread necro but how bad of a job is it to DIY? Looking at it online it looks like if you reuse your ring and pinion as long as those are in good condition it should be fine to just pull the axles/front cover and replace the diff that way? Or should I be replacing everything and doing preload measurements/gear mesh testing like the factory service manual mentions for the rear diff?

      The FD RX7 is the best looking 90's JDM car

      By Kinkstaah · Posted

      in my list I had the R33 GTR as the best Skyline. Infact I had all GTR's (33>34=32), the NSX, the GTO, the 300ZX, the 180SX, the S15 better than the FD RX7. I had the MR2 and the A80 as 'just' better. I also think the DC5R Integra looks better but this is an 01 onwards car. I also think the FC>FD. It's almost like aesthetics are individual! The elements @GTSBoy likes about the FD and dislikes about the 180 are inverse in my eyes. I hate the rear end of the FD and it's weird tail lights that are bulbous and remind me of early hyundai excels. They are not striking, nor iconic, nor retro cool. The GTO has supercar proportions. I maintain these look much better in person (like the NSX) especially with nice wheels and suspension which is mandatory for all cars pretty much. Some (or all) of these you have to see in person to appreciate. You can't write a car off until you see one in the flesh IMO. Like most people we probably just like/dislike cars which represent certain eras of design or design styles in general. I also think the 60's Jag E type looks HORRIBLE, literally disgusting, and the 2000GT is nothing to write home about. FWIW I don't think the Dodge Viper Gen1's have aged very well either. You can probably see where I rate bubbly coupes like the FD. I know we're straying now but the C4 and C5 absolutely murder the Viper in the looks department as time goes on, for my eyes. Wouldn't surprise me if people who love the FD, also love the MX5, Dodge Viper, Jag E Type, etc etc.

      I used to hate R31s, and any of the other Nissans that led up to it, and any of the Toyotas with similar styling, because of the boxiness. They were, and remain, childish, simplistic, and generally awful. I appreciate R31s a lot more now, but only the JDM 2 door. The ADM 4 door (and any other 4 door, even if they are unique compared to our local one) can eat a bowl of dicks. The Aussie R31 is also forever tarnished by their association with stereotypical bong clutching Aussie R31 owners of the 90s and early 2000s. I think the Nissans of the 70s (other than 120Y/180B/200B) are far superior looking to the 80s cars. The 240K era Skylines are boss. The same is broadly true of Toyotas. Hondas don't ever register in my thinking, from any era. Mitsus are all horrid shitboxen in any era, and so also don't register. Subarus are always awful, ditto. Daihatsus and Suzukis also don't generally register. They are all invisible. I think the SW20 MR2 looks fiddly. The 3000GT/GTO is like that but way worse. Too many silly plastic barnacles and fiddly gimmicks ruined what could have been a really nice base shape. Kinda-sorta looks like a big heavy ST165 Celica coupe (and I'm not sure if that's a good thing or a bad thing). I think the 180SX is dreadfully bland. It's not bad looking. But it has no excitement to it at all. It's just a liftback coupe thing with no interest in its lines, and bad graphical elements (ie wide expanses of taillight plastic on the rear garnish). The S13 Silvia is a little better - getting closer to R32 shapes. But still....bland. S14? Nope. Don't love it. S15...a little better. Probably a lot better, actually. Benefits from not being like a shrunk in the wash R34 (where the S13 was a shrunk in the wash R32 and the S14 looked like a Pulsar or something else from the stable on Nissan mid 90s horrors). The Z32 was hot as f**k when it came out but hasn't aged as well as the A80. Keep in mind that I think the R33 is the most disgusting looking thing - and out of all the previous cars mentioned is objectively closest to my precious R32. It's just....real bad, almost everywhere you look. And that is down to the majority of what was designed in the 90s being shit. All Nissans from that era look like shit. Most other brands ditto. In that context, the FD absolutely stands out as being by far the best looking car, for reasons already discussed. Going behind the aesthetics, the suspension alone makes it better than almost any other car.

      If they just called it the "Mazda Tiffany", it would have been spot on.

      Yup but for me its the HR ! Cut my teeth on the old holden 6s in the day ! And here's me thinking in the day it was also the 300ZX and the Mitsubishi GT3000 ! All, as well had good lines, but always seemed to need finishing off, style wise.
