Hi all! The forum has been lacking a DIY for putting your 4WD stag into RWD mode. Firstly theirs a number of reasons you might want to: 2wd dyno runs Saving coin on the tuner pulling it out

Hey team,

Still troubleshooting the 4wd on the c34 s2 rs4s (manual) stag here team. Reminder, car was stolen, came back with 4wd,abs&hicas lights on. Got the abs and hicas back with fuses. The 4wd fuse was gone & i replaced it, front prop shaft was still in there. The light is still on and there is no transfer to the front wheels on the gauge.

I have the r34 manual here, but it is no real help. The R33 solve of reconnect "air evacuation connector" does not shed any light on it. There is no unit in the drivers kick panel.

Does this "air evacuation connector" exist in the c34?

If so where is it physically located on the car?

It might also be the Atessa pump, where on the car does that live?

What do I have to do to test/recommission that?

Cheers team,

Mely

In my S1 Stagea its a very small black plug taped to loom, with a single yellow wire with a green trace going to the plug and a single black wire going to the socket behind the driver's side kick panel.

Have you filled up the reservoir and bled the system? (Bleed nipple at the back of the transfer case and another above the diff)

Here is what I do and have been doing for a while, 4wd light will flash to let you know when it's rwd. When you turn the car off make sure you don't drive it unplugged without pumping the brake pedal!

Turn car on without moving

Pump brake pedal 5 times until the 4wd light starts flashing

You are now in rwd mode as per Nissan manual

To all those people rebuilding driveshafts.... Where do you get parts. I had mine out and sent away for 'rebuilding' and got back shafts with nice boots but plenty of knock. At the point now where im gonna drop the front shaft to stop the impending explosion

What happens if you forget to pump the brake pedal and drive with the wire unplugged? And what problems/damage is caused by running the car in 2wd in this way? I ask as I'm going to do it with mine when it's back on the road, although everyone I've ever discussed this with (including a discussion I'm having with someone at the moment (and who will probably read this shortly, lol)) swear it will break something. Any and all info you have would be great, cheers.

There is no problem with doing this but I wouldn't use it to achieve permanent 2wd because of the need to reset each time. The best way to get full time 2wd is to sell the car and buy a rwd car.

Cheers for that KiwiRS4T. I only plan on doing it occasionally, when I feel the need for a bit of sideways action, so if I fit a switch inline with the wire I need to disconnect I'll be able to do it literally at the flick of a switch... and 5 pumps of the brake pedal of course.

I'm still being told by nearly everyone else I know with a Stagea that doing this will cook the transfer case clutch packs. They claim to know this "from experience", so that says to me they think anyone who states otherwise is wrong, yet not a single one of them have actually seen any problems or failures first hand or even know anyone who has had any problems either. I'm not doubting at all what you're telling me, but is there any truth at all in this? Just so I can clear this matter up once and for all. Cheers again.

It has been cleared up for several years.

This is fine to do providing you follow the procedure in the manual. Pump the brake pedal etc.

As to whether you are comfortable running it on a 2WD dyno with a mechanical linkage still in place is the only questionable thing about doing this.

Thanks wolverine. Wish someone who knows what they're talking about would tell the guys on the "Nissan C34 Stagea owners group" on Facebook this as they think I'm mad for suggesting it, pmsl!!

Here's my experience if it helps anyone out;

Did mine today and found the bolt head can't move as seen here:
post-142543-0-89837200-1457852240_thumb.jpg
and i couldn't get enough 'grab' using an open ended spanner without it rounding and couldn't fit a ring spanner on as above the nut it tapers in.

post-142543-0-41366800-1457852241_thumb.jpg

Ended up buying a 'flare spanner set' from supercheap and grinding it down to fit.

      You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways.

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.

      R32 gtr transmission strength, billet plate

      By cosline · Posted

      Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik

      Spotted on the street....

      By Rezz · Posted

      Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
