Removing R32 Hicas

[murrayis]

Well I am in the rocess of putting my new engine into my R32 GTST and while the old engine is out am goign to remove the entire hicas system.

I think I have it sused but jsut wanted to confirm that what I am removing is correct.

From looking at how the system is setup I figure I can remove everything related to FEED1 and Return 1 in the following picture

At the pump side of the system I can remove FEED 1 and Return 1 and block of the feed from the pump and the return to the fluid tank below

I read in a previous HICAS removal writeup that you can remove the rear half of the power steering pump? is this possible or am i better off just blocking up the feed from the rear side of the pump that goes to the HICAS system.

Thanks in advance for your experience and replies

Spoken of 1000 times, on SAU and NS. Be sure to have a good read of the DIY that exists.

Blocking up the pump in a no-no, as the over pressure (can) cause it to fail.

Removing the rear stator has been done, but again, the bearings in the pump where designed to take a particular load, having half the axle unloaded causes it to fail as well.

I've just done what everyone else has done. Routed the rear stage through the stock PS cooler, removed all the lines solenoids, installed the lock bar.

Must be great doing it with no engine in there!

The more threads I read about the removal of the Hicas system the more difficult it becomes

So pretty much i can route the feed back to the return just looping it back on itself? so that the oil goes to the oil bottle up top?

eg. the pic below:

Would that work?

[GeeTR]

Sure can, though I personally would use the cooler, specially if you intend any hard work / drift for the vehicle.

...More difficult it gets reading about it, or doing the modification?...

[benm]

Doing the modification.

[GeeTR]

Yah, i procrastinated for a year or so before doing it. Didn't like the idea of heavy steering Sucked it up, and told myself if I experienced that, id just chuck one of those Tomei black box's on.

What oil cooler? there wasnt a factory one on there :S or do you mean the tube that went through the front and looped back past the radiator?

The tube with fins on it, that does a L shaped loop, in front of the AC evap
