Ryno's R32... Over A Decade And Counting

[Ryno]

Good move, I don't regret installing it for one second.

The other great benefit is that the sensor will be installed in the correct location in the exhaust. This will give you a more accurate reading of the AFRs (when you get it tuned) rather than a sniffer in the tail pipe.

I've done a fair bit of maintenance to fix a few ongoing issues over the last few months. The car now has all the rubber suspension bushes replaced with Whiteline/Nothalane. It also has a new air conditioning condenser, heater core and rear wheel bearing replaced.

Of note, my car has had an intermittent steering wheel vibration at around 100 kph, that I've been living with for as long as I can remember. It wasn't because of a wheel imbalance as I've had several tyres/rims over that period with the vibration always persisting. What fixed the problem was replacing the front inner/lower suspension bushes. My upper camber and caster bushes had been swapped swapped out for urethane years ago - so the lower ones were the last rubber ones remaining.

Time for some updates... Pics of the new Aircon condenser and Heater Core that I put in...

I ended up reusing the plastic heater core fittings not the metal ones shown in the picture.

I found that the bolts and washers that hold my MX Performance plenum top down onto the lower runners weren't really up to the task and the washers had deformed. So I ordered some titanium flanged hex head bolts to replace them.

Out of interests sake, I wanted to know the weight saving, seemed like a good job for the wifes Thermomix!

So for around $100 thats an awesome weight saving of 100 grams! I'll only need to spend another $500,000 on titanium bolts and I should be able to get the weight of my car down to the same as a Lotus Elise!

Since going to my new exhaust manifold setup the car has been a fair amount louder. I finally decided to tackle it back in November and swapped out the rear cannons and centre muffler with new Magnaflow mufflers.

Out with the old...

My latest drama to fix was a leaking Power Steering rack...

I was able to swap it for a reconditioned rack that cost $350. But at the same time I wanted to finally fix a problem that has been bugging me for around 10 years!

Ever since swapping to the RB25DET engine and removing the HICAS I've been living with heavy steering as the power steering goes into a limp mode due to no speed input.

The solenoid on the power steering rack gives full assistance with 12 volts and the assistace reduces as you reduce the voltage. So I purchased this voltage step down module from Jaycar...

I have wired that direct to the Power Steering solenoid and can adjust the voltage as I see fit. It is still not going to be speed variable (like stock) however I can tweak the voltage to find a happy assistance that works ok at all speeds.

Checking the output voltage...

much nicer exhuast

Thanks Glyn, yeah I'm very happy with the exhaust... it looks the business and the sound has reduced nicely while still maintaining the unique note from the twin pipe setup.

Good work on the power steering rack solution! Have you tried it out to see if it works?

[Ryno]

Yes I've been driving it to work every day this week. At the moment I have it set on around 8 volts and the steering is nice and light.

I'm just a bit frustrated that I've only fixed it now... It's such an easy solution, why the hell did I put up with crap steering for 10 years!?

hey ryno

i have a 93 r32 gtr that still has hicas but occassionally has heavy steering at low speeds/parking. Can the above solution you put in place be useful for my situation?

Absolutely... all you are doing is intercepting and controlling the voltage going direct to the power steering rack. It's a very simple and effective fix.

Noice.

how much was the new condensor and where did you get it from?

[Ryno]

I bought it through Nissan spare parts here in Australia. They found one in country (WA from memory) and got it in for me.

I think it cost around $500, but not 100% sure.

fantastic ill keep it in mind if it continues to play up. Its been bugging me. Would you consider doing a diy write up?

[Bushy]

Well done on the power steering solution, I unplugged the solenoid a while ago as it wasn't very consistent so it's currently heavy all the time, I'll definitely be doing that!

I've just done up a DIY for the power steering fix, once it is approved by the moderators I will provide a link.

Thats a fantastic DIY. Well done and thanks a lot. I will definately be trying this on my GTR
