I recently purchased my first Skyline and the owner stated that they had done the HICAS delete. I am unsure what path they took, but I have the dash light on AND he claims to have utilized a Pathfinder power steering pump. I read through the various HICAS posts and saw lots of good ideas,  but I did not see this listed as one of them. Has anyone had any experience with this? I got the car and the belt was splitting, I used the part number from the belt to replace it (the belt looked relatively new). Now, the second belt has shredded in less than a week. The pump has a standard tensioner with a grooved track, one long bolt that adjusts tension, and another bolt that locks it in place on the track and provides minimal in and out adjustment. Everything looks ok, but clearly if I am eating belts there is an issue. What I have noticed on both instances, is that the belt splits directly down the middle; I am unsure what this is indicative of.

Will it hurt the power steering rack if I drive it without power steering? My temporary solution has just been to drive it manually, sans belt. 

Cannot comment on Pathfinder pump.  But realistically, so long as the pump places the pulley in the right spot, just about any pump will do.

HICAS "delete" does not imply that the HICAS warning light will not illuminate.  If you do it wrongly, you will get the code.  The HICAS CU is responsible for providing your variable rate power steering.  Therefore, to retain this, you must retain the CU.  If you remove the remainder of the HICAS system (actuators, sensors, etc) then it will chuck the shits and throw up the warning light.  The solution to this problem is to leave the larger of the two connectors attached to the back of the HICAS CU and disconnect the smaller of the two.  The important parts of the HICAS will still do their job, but no dash light.  Or, you just remove the bulb from behind the dash.  The plug is easier.

Yes, you can drive without power steering.  It is much much harder work, especially at parking speeds, but it actually feels nice on the move.

Assuming that the Pathfinder pump is incorrect in some way, you should obtain an early RB25 PS pump as an easier approach to making sure that the pump will line up with the other pulleys on the engine.  Or, you can just put an original R32 PS pump back on it and use the rear stage of the pump to run a separate PS cooling loop.

Ok, I was most concerned about running the power steering “de powered” I know some cars are sensitive about that. 

The dash light I was referring to more as I thought it was evidence of some kind of HICAS work. I will follow up with the previous owner and see if he can explain what all has been done.

HOPEFULLY, I won’t have to purchase any extra parts, but we shall see. The other options are certainly easier; I would just rather spend the money on fun stuff.

    • Put a fuel pressure gauge on it. Replace the turbos. Probably completely separate issues.
    • What copper washer do you guys use on the bleeder bolts? The existing one I have I had no idea where to find it in a local store, I did buy some online but that are only 1mm thick whereas my old one is 2mm+ thick and when I put the new washer out and squeeze the top radiator hose I can hear a bit of air but not with the old one. Does this matter? The new one doesn't leak, but the inner diameter is a bit loose whereas the old one threads on the bolt.
    • Howdy all, after being out a few weeks ago on a spirited drive in my GTR I have 2 issues that oddly have appeared at the same time. Whilst accelerating quickly through the gears all of a sudden i’ve lost power at the top of third gear (below redline around 6000rpm) for no obvious reason.    From that point onwards the car has been running rich on idle, won’t really rev under load without a ton of black smoke and the odd backfire, and dying as a pull up to a set of lights unless I keep the revs up around 1500rpm. In addition when shutting down the car that same night (I was 10 minutes from home) I noticed one of the turbos was significantly noisy on wind down when shutting off the engine. After letting the car cool down overnight it starts up fine, although once it gets to temp the revs start to creep up and down, the exhaust is darker than it should be and it also sounds like it’s running rich (fat note) I’ve put a new set of plugs in it - no change, the old plugs all seemed OK with two of them being somewhat richer/fueled up than the other 3 with 1 being borderline. I’ve smoked tested the intake system via the front of the Turbos, found a split vacuum hose going to the factory boost gauge sender, which I have since replaced.  Also found another leak on the gasket coming off the rear turbo outlet, have also replaced this. After fixing both of these leaks - still have the running rich issue. I’ve also tried another pair of AFM’s - no change here After pulling off the front turbo intake pipes, there is obvious shaft play in the front turbo, which now hisses loudly on light revvs although I can’t see why this would make the car run funny even under idle. I’m curious to know why it’s running rich before I potentially replace/rebuild turbos. The car is completely stock <50,000kms  other than an exhaust. Oil and coolant are all clear. I haven’t bothered with coil packs as it looks like they won’t be the issue due to condition of the plugs. Any help appreciated as I cry myself to sleep!
    • No probs at all. I used to love trying to dig up obscure info for those in need where possible going back 20+ years on SAU.  I did have another look and couldn't come up with any closer match. I'm leaning towards those skirts in your first pic are custom fitments, cut down/extended or from another car entirely and modded to fit an R34 sedan. I would've thought someone in Japan had them and taken a photo at some stage over the last 2 decades but there's nothing. Someone out there must know surely.
