Hey guys - you are f**king up an otherwise good thread. Should you like to bicker about who knows what you might like to do it off line. This IS a DIY thread and I would suggest that most people visit

Hey can anyone tell me what the torque rating is on the two bolts that hold the hicas unit amd/or what torque should i use on the replacement locking bar. Sorry just like to do things properly.

hey jason, I have one of geoff's bars on order, and will need it fitted (no tools here in sydney :rofl: ) so does your $120 include the allignment?

on a side note, I got home tonight with my GTR blowing a lot of smoke as I pulled in the garage! the engine is only 1500km old, with 3 oil changes under its belt! and the turbos are new at the time also...... oh and low boost too! only .9 bar !!!

Im off to ring the builder in the morning, but I am seriously hoping it is something minor or there will be tears!

maybe a blocked PCV? :S:S:S

cheers, and thanks to geoff for taking the time to make these for us guys!!!

Just to clarify some of the questions about R32 GTR....

To remove HICAS altogether.....buy one of Geoff's bars, and either....a new power steering pump with 1 output, or a bolt the right size to replace the rear line outlet.

Disconnect the 2 ball joints at the hubs, and then remove the 2 bolts holding the HICAS bar to the subframe. Be amazed at how heavy it is.

Disconnect the 2 lines from the chassis that go to the HICAS bar, there are a couple of brackets holding the lines to the subframe.

Disconnect the 2 lines right to the front of the car, right up at the HICAS solenoids next to the plenum.

Remove both inlet and outlet lines from the HICAS solenoid (these lines run back to the power steering pump and power steer reservoir. Unlpug the wires and remove the bracket. Enjoy how much easier it is to remove your oil filter.

Remove the rear line from the power steering pump, unbolt the brackets and cut the metal pipe as it links around the power steering lines underneath (unless the engine is out in which case it just lifts out :rofl:)

Remove the line that run from the HICAS solenoid to the cooler to the reservoir. Remove the whole cooler and all its brackets. Remove the other line that runs from the solenoid to the pipe you just cut.

Put a nice big bolt in a short piece of line to block the empty exit from the reservoir.

Clean up the power steering fluid that is all over your garage floor.

Like anything, double check to make sure you have the right pipes, esp before you start cutting! There will be only 2 power steer lines left in the engine bay, it will go from one of the reservoir outlets to the front of the power steer pump, around the engine bay to the steering rack, then back around the back of the engine bay and back to the reservoir.

That's great, I think that's what I've been searching for. I have a R32 GTST. Is this a similar setup to the GTR? Also, can I use the original pump, or what is an alternative pump to use? To clarify, can I remove eveything bar what goes from the reservoir to the pump, to the rack and back to the reservoir? I have a couple of metal plugs to go with the 2 spacers and 2 domed nuts from the locking bar kit. Where do I use them?

Thanks

Mitch :P

Hi Duncan,

Have you gone through this process and have it running in your car? Is all OK without the extra line (that used to go to the HICAS solenoid) and without the cooler?

In my mind the extra line may have relieved pressure in the system - though I would prefer to listen to your advice as someone who has gone through the exercise!

Yes we;ve made the changes above and given the car a *very* thorough work out since. No problems with the car or power steering.

Our main concern was whether the pump will last with 1 outlet just blocked off...dunno...if it dies we will be replacing it with a 1 outlet pump like an r33.

I'm not sure if a 32 gtst is the same but I suspect it is

Is the R33 pump a direct replacement?

Which is the Hicas outlet on the R32 pump?

Thanks again

Mitch:)

I'm not sure but apparently so,

And the HICAS outlet is the rear one on the Power Steering pump. But for goodness sake before you start pulling it out...double check everything!

Right, blocked the rear outlet from the pump, and also the return to the reservoir.

Haven't yet swapped out the Hicas rack, but there is Power Steering fluid pissing all over from somewhere or other. I thought it was from the main return to the reservoir, so replaced it with a braided hose, but after taking it for a run out, there's an explosion of fluid all under the engine, hoses, suspension-everywhere.

Is there a possibility that the rear outlet being blocked is causing excess pressure in the system?

      Misfire/stalling issues

      By Chris_Guthrie · Posted

      Any recommendations on a decent replacement manifold that doesnt break the bank or require additional mods for the stock turbo setup? I figure if I'm going to pull the manifold off anyway to fix the studs might as well replace it.

      Misfire/stalling issues

      By Chris_Guthrie · Posted

      So I checked the turbo out today. Very minimum play at all just enough for the oil to take up when it's running. I did find an exhaust leak at the manifold. 1 stud all the way in the front is missing and the one all the way in the back is broken off. Front has visible signs of an exhaust leak. I'll fix that soon but that's not my problem still.  I also found that the nipple coming off the turbo had the hose capped off and a hose ran from the j-pipe by the bov going to the wastegate. I removed that hose and capped that nipple and put the turbo nipple hose back on the wastegate.  There was a ton of oil residue all through the charge side of the intercooler piping going to the throttle bodg. I'm thinking that's from the pcv. Doesn't seem to be coming from the turbo that was all clean on the pipes side.  Haven't had a chance to check fuel pressure yet, haven't had time been having to pull a lot of doubles at work. I did pick up some carb cleaner to clean the iacv but wanted to make sure I had a fresh gasket in case the old one rips when I pull it off.  I'm waiting on a MAF that was supposed to be here today but delayed to Monday. Have a double Monday and Friday and work all of next weekend so going to try to find some time in the middle of the week to try that out. Did about a 10m trip around the block today and towards the end the issues were coming back. Fingers crossed on this MAF but if not just going to throw a fuel pressure gauge in and see where I'm at.  Did notice today that I can definitely hear the injectors pulsing. Very audible clicking coming from them. Assuming that's normal? Should also mean CAS is functioning somewhat properly. After it warmed up when I started it the intermittent misfires came in again. Did start doing that before it was fully warmed up.

      GOT SUM's RB34

      This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O

      Thanks for all the replies! I also wanted to ask if wheels that were fitted on Ford Falcons would fit the 350GTs as well? In the area I'm at there aren't that many options for secondhand wheels and new ones here are way out of my budget. From what I've seen, most of the wheels that are available that were fitted on Ford Falcons have an offset of +33 to +36, with a centre bore of 70.5mm whereas the stock 350GT's ones are 66mm, can't seem to find any hubcentric rings that fit that difference though.
