How to Remove HICAS in your Nissan Skyline R32 GTST GTR and GTS4 - DIY Hicas Removal (RB20DET, RB26DETT)
There are a lot of ways to delete HICAS on the R32 Skyline, but this method is (in our opinion), the easiest, cheapest, and works for all models of the Skyline: GTST, GTS4, GTR, etc. for all engines RB20DET and RB26DETT. The easiest method in the past was to swap over to an RB25DET HICAS pump, but with those in short supply, and demand on 25 parts going through the roof with the R33 Skyline now legal, there is a new “better” option.
You need just one bolt from Amazon, found here:
(Note on the above: when the M16x1.5 is sold out it will bring you to another size bolt when clicking the link. Make sure you order the M16x1.5)
And some additional misc items (optional):
This bolt blocks off the HICAS Port at your R32 HICAS pump, and then you can trace all the lines after that and delete them fully. You remove a ton of junk from the engine bay (along with weight!) and a lot less crap to deal with.
With the Power Steering pump removed from your R32 Skyline, install the bolt and crush washer to the rear-most port. I added some blue Loctite just in case, but you shouldn’t need it.
The next thing you need to do is open up your HICAS pump and delete the vanes that pressurize the power steering fluid. This seems intimidating, but really isn’t. The back of the pump has 4 14mm bolts that come off, and then use a magnet to pop out the vanes.

From here, just reinstall your power steering pump, and delete all the lines. Just trace it all from the port you now blocked off, all the way through to whatever it links to. There will be a pump bolted into the engine bay on the driver’s side, a loop in front of the radiator for cooling, and then back down to the pump and up to the reservoir. An Image below shows everything removed:

Cap off the open port of the reservoir using a vacuum cap, and zip tie the cap in place.
Now you should install whatever rear HICAS delete of your choice to truly remove the rear HICAS balljoint, but this will at least remove all the front HICAS junk from your R32 GTR, GTST, or GTS4.
