I would just like a simple answer will a 35.Z diff fit or not because and aftermarket one is x3 more and I need to know how much to.save for. Sick of going into my driveway and the stupid open diff spinning the wheel which has less traction which is the one in the air

Why dont YOU have a look at the mounting positions, the stub axle bolt patterns and make up your mind, or are you waiting for someone to magically say yeah I changed the Diff in my white V35 VQ25DD sedan to a 350z one and it worked?

Do you want a LSD if its going to make your car signifigantly slower? Thats what we are telling you to check!

Can't swap the stub axle over, they have different spline configurations. Can you swap the Outside flange off the stub axle! Or swap over to 3.5 litre driveshafts.

And you still don't know if your going to a longer diff, making the car slower.

Good luck.

Btw, super random first post, what are you doing here.....?

Ok I reread your post , all good much easier to just swap the flanges from the original diff to the vlsd . I don't know why there isn't more information on the net about it , it' just seems like such an easy swap to something factory and a lower price than an after market product

Ok, I read and tried to understand your post. But I'm failing.

What are you trying to Swap? from what to what?

Maybe this will explain a bit better

Compare the pair....

Your original

http://www.importmon...6.jpg&title=V35 R VQ25DD

Z33

http://www.importmon...791.jpg&title=Z Z33 R VQ35DE

Doesn't look like it would work, agree?

The flanges on the pictures on these diffs , the vlsd has the evenly spaced 6 holes to bolt the axle to the flange , where as the original v35 diff has 6 holes but 3 paired ...

So I was looking at the possibility of swapping the "stub axles" the part that slides into the diff to allow the shafts the mate with the diff ..

Now seeing the pictures that youbhave posted looks like the stub axle is longer obviously . So changing the full axle may be the trick

Hi

I'm also consider going to a LSD in my car but its a 300GT. Its diff ratio is a 3.13 ratio so if I go to a quaife will that mean quicker acceleration but lower top end?

Will be doing a engine swap next year but keeping the gearbox as its the same as the standard VQ35 so built to handle the power.

Cheers

A quaife will not change the ratio of your diff. It is a part that fits in the centre, not part of the gears. We were talking about a wholesale pumpkin (the whole unit) change.

That being said, might be wise if the stub axle flange fits, getting a manual 350z vlsd diff (3.5:1) as it would give you a useful boost in acceleration, as well as the LSD component.

Top end isn't really something to worry about, as long as cruising rpm is still comfortable. Really taken your car past 240kmh? Otherwise not going to effect you.

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.

      Skyline v36 350GT sedan hunting on idle

      By Robot · Posted

      Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣

      After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
