Hey all Why does my idle move when im turning my steering wheel from side to side?????? The car idles normally but when i start to move the steering wheel the idle starts to move. what the hell is going on???

One last thing. My dog today has ruined my weekend. I woke up today and my dog has eaten the wires under the car at the rear for the 4WS. I have taken it to the auto electrician they have wired it all up again BUT......... the 4WS doesnt work. F%#$ dog im going to kill him. Any ideas what the hell it could be. The auto electrician has now unplugged the 4WS and he is going to have a better look at what happening with the computer that operates the 4WS. pisses me off though cause i now have the flashing light HICAS contstantly on now. annoying really.

It's normal...with the engine idling turning the steering wheel causes increased pressure in th PS fluid system and puts load on the pump. That load is transferred to the engine, which causes the idle to drop. R32's have an extra pressure sensor in the front PS lines that tells the ECU to bump up idles in situations like this (a bit like the air conditioner fast idle switch). R33's might be different, however.

most cars these days have the idle up solenoid which tells the computer to raise engine revs to compensate the extra load from the p/s when pressures increase(movement side to side) As for u hicas, get a lock bar. Try going to a mechanic with a scan tool and they might be able to delete the hicas light, or take the fuse out(if it has one) for the light :(

      The cross sectional area of a circular hole scales with the square of diameter. So a 2mm diameter hole is 4x the area of a 1mm hole. Not double. The 1.7mm hole is nearly 3x the area of a 1mm hole. You do not need restrictors at both ends of the oil supply line. If you have new, additional restrictors at the turbo end, that you did not have before, then you do not need a restrictor at the inlet end.

      Hi all. Been a while but things are moving along. I just have something that I am wondering about. Since I will use OEM turbo oil pumbing, I got myself a new bolt, the one that goes into the engine block oil feed. As I recall (and see visually) this bolt comes restricted with I think a 1.7mm hole? Not quite sure but it was something around that size. The turbos have 1mm restrictor bolts installed, as necessary due to ball bearings and my higher oil pressures. Can I now just use that OEM bolt with the 1.7mm hole in for the engine block or will this actually be too much oil flow restriction and I have to drill it out first? In my head it would make sense for the bolt to be at least 2mm wide as both turbos take "1mm of oil flow". Do let me know if my logic is flawed here, I just want to make sure I don't kill my turbo bearings with too little oil. Don't know if I can trust the saying I read somewhere that ball bearing turbos essentially only need an oil mist

      Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.

      Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.
