Differential Upgrade?

I just installed a Tomei Technical Trax 2-Way with a 3.9:1 final drive.

I like the final drive. I'm not so sure about the high yaw clunking of the LSD itself, since my goal with the car was a streetable car that could be tracked.

I'd really like a Quaife, but it's well out of my price range.

is your car auto or manual?

Mine is auto..... most people would tell not to bother... but i want exactly what you are after a streetable car that i can also take on the track....

Apart from the clunking... did you get the extra downforce power?

Manual.

The rest of my car works for my goal. The only change I make for track days are the rims/tyres. Its not too noisy, its not crazy stiff, I've got a stock interior, the pads don't need heat to work.

As for the LSD, I haven't noticed much of a difference yet as I've not really opened the car up. When the rear breaks away its lost a lot of its progressiveness. It gets a lot more sideways a lot quicker, which was a bit interesting the first time it happened.

When I gave the throttle a prod around a roundabout in the wet on Tuesday it didn't break traction where it would have with the OEM VLSD.

I'll give it a couple of months of street driving, and at least 1-2 track days, before I make a final decision on whether I like it or not.

Thanks for that info...

I think before i go the LSD i am going to go the cheaper option and get set of Selby's sway bars for extra downforce...

The guys down there (superior suspensions) say they have created a system which really makes a difference to the handling of the car......

When your heading out to the track next, let us know....it might be good to get a few vq35's going round...

Sway bars are the single best handling upgrade for the car. I'm not sure about the V35, but on the Z33 the ride/handling compromise for the coilovers is almost spot on for a daily driver that only occasionally gets tracked once you do the bars.

Does your car come with the VLSD? If so, there's plenty to do before you upgrade it. Honestly, I didn't really need a new diff as the old one was still holding up OK. If I tried to slide, both wheels would light up. It was only around the tightest of hairpins that it would single peel.

My next definite track day is Circuit Club's 5th Year Anniversary track day at Wakefield - but it will probably be really busy.

yeah it comes with the VLSD... im going to do the sway bars within the next few weeks... just got to get a spare moment.. im always on the go... ive also finally located a full manual 6speed box out of a Z... so also thinking about putting that into my V35... but before i do that - i want to test drive a 6speed v35 ...and see the difference.... if its major im doing it... if not then i will just leave it...

The auto is a 5 speed, right? That means you'll be running a 3.2:1 final drive. If you do a gearbox swap without changing the diff ratio, you still won't see the acceleration of your manual brethren.

I always thought that if I was to go FI I'd run that 3.2:1 FD, but so far I haven't seen too many turbo owners in Australia looking at doing a swap. The only guys I've seen even consider it are in the States, making big power with built engines.

Hi Guys sorry to bring up the Old threads.

Does the CPV35 Premium Auto comes with LSD? Some people said no but some people said it does come with VLSD. Kinda confused here. Mine is 2003.

cheers

Yer, I've brought this up before on this forum, I have an 03 prem auto coupe also, the story is all 5 speed autos are ''NOT'' fitted with VLSD's, anyone who has got it must be fitted with an after market Diff! Just jack the rear end up and turn the hoop's to find out. Forgot to mention also, all auto 5/AT 350z's ''ARE'' fitted with VLSD's as STD were the V35's are not, bit strange when both run the same drive train and the same design platform, maybe Nissan has some reason for it, anyone else got some answers.

Does this trick work with VLSDs? I just figured the fluid was so slow to react that a hand-turned wheel couldn't make it harden.

I never tried it with the stock VLSD so I wouldn't know.

      Coolant leak?

      Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.

      Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.

      Hi Everyone I am from West Pennant Hills in NSW. Been too busy until recently to attend to my RB25DET Series 2 engine until recently. I am planning to stick it into the S15 shell at this stage, unless a nice SR20DET turns up... For now, i am going to try and get the RB25 running and working well then decide what gearbox to use. My preference is to retain the SR20DET  6 speed gearbox and tail shaft to retain as much and least modifications as i can avoid. I am an old guy and won't be doing any heavy drifting so i don't need a bullet proof gearbox Does anyone have experience with starting the RB on a stand? I got everything setup as much as I can with the info i can find... endless searching and videos on Youtube I would be great to get some pointers Cheers Songo

      Hey all, Recently have had my s1 r33 gtr serviced and noticed my coolant reservoir was topped up to the max line. Took the car out for 1 yesterday and noticed today the reservoir is completely empty.  Any ideas? Radiator is full
