Not sure about the 4WS... The Japanese R31's came in 2-Door, 4-Door Hardtop, 4-Door sedan and Wagon. The 4-Door sedan (as sold in AU) was never as popular as the Passage (hardtop), especially the Twin Cam turbo models. The Sedan was the ugly duckling of the line up I guess :)

Heres a pic of a Japanese market 4-Door R31:

The series 1 passage didn't have 4WS, but all the coupes and S2 and S3 passages did have the 4WS.

I have a Passage 85 build date but complied as an 86 model. It's the first series and has HICAS 4WS.

I believe HICAS was an option with IRS models, but not available on live axle rear ends. I was wondering if IRS was available in the sedan, i'm not sure but someone here may know...

You see very few pics of the sedan variant on the web. Also, mostly they appaear to be the RB20E or DE, CA18S or diesel powered variant when you do see one....

Passage or Coupe - me rikey very much.... But as for the sedan, the aussie version is probably in this case better than the JDM one, strangely.

I believe the Sooth Effreekin version of the sedan runs an RB30E (on leaded fuel with no cat and a bit more power) and the IRS rear end.

Hmmmm yep... I'd say exactly the same thing about the N13 Pulsar... it seems the (later) Japanese version got better tail lights (al la Skyline) but the earlier models all got the crap front end ie: sqaure lights/indicators.

as far as i know.. all the JDM ones that I have seen that have the pillar, have been non-turbos or the povo-packs.

HICAS that slides the whole crossmember?! - that I would like to see.

um, frigjam - why do you have 3 import HR31 ???

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
