Since doing my engine conversion I pulled all my hicas out and put a lock bar in, changed the pump to a rb25 pump, made sure all the system is bleed, and the steering seems heavy still. Now I do plan to put a non hicas subframe in with all new arms and stuff just havtnt done it yet.

I don't know if its something I have missed but do u have to do something with the hicas ecu in the boot like cut and join to wires to trick it?

If anyone can helpt that would be good, sick of semi heavy steering haha

Courtesy of my Neo transplant (and non-HICAS subframe) I deleted everything to do with HICAS, except the HICAS computer and the sensor on the rack. The PS in my car is exactly as it has always been - ie it works properly.

The only unusual thing about my setup is that I disconnected the smaller of the 2 plugs on the HICAS computer. This was in fact done 14 years ago when I first got the car because the HICAS was crook anyway. It's all it takes to disable it on an R32. It may be necessary for you to keep the HICAS computer hooked up to the larger plug.

Well yer thats what I did to my car, pulled all the lines out to the rear of car, pulled solenoid out everything. Swapped pump to a 33 pump with just the one port coming off it, Just didn't have time to do the subframe, so lock bar so time being it was. I havnt actually checked the rear plugs, don't think I have undone anything back there.

Is there any plugs that plug into the power steering rack itself fort the hicas I can't even remember if there was.

Tried blocking off the solenoid on back of the rack didnt work at all, just blew oil out the bottom of bracket. Does anyone have any other sugestions? Like any wires that need to be earthed out or at the ecu?

And also the solenoid on the rack with the 2 wires coming out of it with the plug on it what does that have to plug into, mines not plugged in, thinking thats causing the dramas to?

      Seemed to be good when Jeff owned it but they did a shit job on my car, probably worth a think before spending 10's of thousands of dollars where they might be cutting corners

      Starting with issues 1 - 5, we have already run into a problem...!  Issue #4 contained 2x front brake calipers, instead of 1 caliper and 1x steering knuckle. Will have to call DeAgostini on Monday to sort it out. Anyway here's some photos.  Issue #1 is the front bumper, headlights and number plate. Issue #2 is the front wheel (with "We produced with spartan air." text on the centre cap!) and tyre, the front lip spoiler and cylinder head cover with ignition coils under the centre cover... which will never be seen again. Issue #3 is the bonnet and cylinder head. Issue #4 is the front strut, brake disc (with laser etched metal discs) and brake caliper. I stopped here because of the issue with the missing steering knuckle.  Next update will be #5 - #10 in a few weeks.

      DeAgostini is one of a few companies that release quite large (the largest commonly available size actually) 1/8 scale models in a series of weekly issues over 100 - 110 instalments.  They release different models for different markets and DeAgostini Japan have release the BNR32 Skyline GT-R Nismo last month. I've made two of these 1/8 scale sized cars (one an R35 GT-R from 2012 - 2014, the other I'm just about halfway through, a BNR34 Skyline GT-R from the 2Fast 2Furious movie) so when this R32 was announced there was no way I could ignore it as it's my favourite out of all Nissans.  Each issue costs around $20 so it costs about $2.2K when completed. I suppose it is very expensive for what it is, but the quality and details are really very good, and there are many "gimmicks" like fully functioning exterior and interior lights operated with a remote control, working steering, all doors/bonnet/boot/fuel lid open and close, the side mirrors fold in and it even has a speaker for the engine revving sounds when you turn the lights on.  Each issue comes with a magazine that tells the story of the BNR32 Skyline GT-R Nismo from the first design stages of the BNR32 to Group A homologation and the various racing version that were run in the Japanese Group A and JGTC, and Australian Group A.  So I plan to update the build in this thread 5 issues at a time.  https://deagostini.jp/r32/?srsltid=AfmBOooKjxDc4EUK2rmXqMBPgyHfFJ24s4oEPJBNpnF-lFlsRoW0PE6P
