    A31 Rb20det O2 Sensors

    in Forced Induction Performance

    Posted

    G'day.

    I want to replace the downstream O2 sensor in my A31 Cefiro, factroy turbo.

    When fitting my cat converter, I noticed the 2nd O2 sensor is different to the dump pipe one. It also has 4 wires and a different connector.

    When lookin on the net I cant seem to find this downstream sensor for sale.

    Has anyone come accross this before?

    I would like a cheaper option as nissan want $220, and there is none in the country.

    Thanks,

    Matt

    A31 Steering Question

    in Suspension, braking and tyres

    Posted · Edited by just_matt

    When I got the car it had no power steering, the hose from the pump was missing.

    It doesnt have a hicas rear end and the resivoir has 2 returns and 1 feed to a single type pump.

    I have thrown the solenoid out, but found a pic on the net which is similar.

    The sol. in mine only had one side to it, with 3 hose fittings.

    I this pic there is actually 2 solenoids togeather, The blue square show what mine included.

    The other is my steering rack, the top right hose went to the solenoid.

    I removed this and plugged it, but still had no power assist.

    I want to remove any hicas/speed adjusted assist or whatever so was thinking of getting a new rack.

    A31 Steering Question

    Dan, Im trying to get less turns of the steering wheel to acheive full lock, not actually looking to improve the angle of wheel at full lock (at the moment).

    From what i can find on the net,

    S13 Stock rack 3.1 turns lock to lock

    S13 Hicas rack 2.6 turns lock to lock

    Therfore the Hicas rack will give a more responsive steering.

    Front Left And Front Right Ride Height Not The Same.. Why?

    You could try raising the vehicle, loosen all bolts for rubber bushes enough so they can twist, lower the vehicle completely (weight on all wheels), check ride height Left and Right.

    If all bolts/nuts for your suspension bushes are slightly loose and it still sits wrong, then atleast you have eliminated a possibility.

    Its not how tight you have done the bushes up, but the angle of the control arm when you tightened them up, compared to the angle of the control arm when the wheel is loaded with weight.

    One may twist more due to softer rubber, age, cracks etc...

    I have a Cefiro with a steering rack that appears to be Hicas, (it has an extra fitting that went to a solenoid, which is now removed).

    I have read somwhere that hicas steering racks have less turns lock to lock? Is this correct?

    What I want to know is, Can I buy a S13 rack and swap the internal parts over to get a more responsive ratio?

    Thanks,

    Any luck yet Mate?

    May need to check the fuel rail pressure?

    Try disconnection fuel pressure reg, blocking hose so there is no vac leak into manifold, and crank it. I think this will give you full fuel pressure...

    Or also try tuning the key on (wait 5sec) then off, then back on about 5-8times before you crank it (fuel pump might be getting lazy, but if its failed this wont help).

    You may need to check your plugs if your have been turning it over alot with out it firing.

    When you looked at the plug last did they look 'wet' from unburnt fuel?

    An Injector 'Noid light' will tell you if injectors are being fired.

    Hi,

    I recently bought an A31 Cefiro that is missing some power steering lines.

    The vehicle has a non-hicas rear cradle, single pump type, and there is 5 fittings on the steering rack, which doesn't appear to be Hi-cas, although maybe Speed Adjustable Steering -SAS???

    There is also a solenoid which has 3 fittings, 1 goes to the resivour and 1 to the rack which can be seen in the picture, and the last is not connected.

    I would like to find out if the solenoid can be removed? And what fittings on the rack are pressure and return?

    Here is a picture of the rack.

    Thanks
