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.

      R32 GTR Limp Mode?

      By Nydt · Posted

      Hey y'all, I have a completely stock 1991 R32 GTR, yesterday I took my car out and went for about a thirty minute drive. It was fine on the way there but when returning home I think the car might have gone into a limp mode. I was cruising in 5th gear around 130km/h, the hicas light came on and there was a significant loss of power. About a minute later I hear a thump, the car starts driving normal again and is fine the rest of the drive back. This is the second time its happened, same as now it was fine on the trip there. On the way back it had the hicas light on but that time I would feel the power going in and out before hearing the same thump and it being fine.  I have no idea idea what causing this, but if anyone has any ideas it would be great as a start chasing the cause of this. Also I can provide more details if needed. Thank you

      Steps to DIY sanding car back ready for respray....

      By GTSBoy · Posted

      When sanding across a convex panel, you need to sand, as much as possible, at right angles to the curve. If the panel is compound convex curved (ie curved in both directions) then you are SOL and have to use "craftsmanship" to get it right.

      Duncan's V37.......race car?

      Duncan's V37.......race car?

      By MBS206 · Posted

      This sounds like me. And then why I leave shit that I had previously hobbled together broken. Lately I've changed strategies to "If I don't want to justify the money on decent stuff, I'm not going to justify hobbling it together". I'm still for DIY, but DIY it properly is more my thing. However, I am terrible on not setting up backups still... Which reminds me, I need to go backup some of my work VM machines... Oh, it's also why I've become a lover of building things into Docker Containers... Then I just need a machine that can run docker, and bam, that specific system is up and running, on the specific versions of everything I need for it to run (In the event a change in required software version breaks something else). Also, these days, my steep learning curves are spent with work related stuff, and on very varied projects, that my want to do other random projects like build a dashboard for my own car has dwindled away to "I just want the car running", which is my current PITA, as I'm getting the Landcruiser usable again, and it has just been non-stop the past 6 to 8 weeks of buying parts, and working on it. Oh, and tools that are meant to be fit for purpose... And they break, because 25 year old 4WD decides it's stronger... But by the time I have it ready to roll back out the drive way, nearly all the stuff in it will have been touched and serviced, so the damn thing better give me NO FREAKING ISSUES, for at least the next 50,000KMs! Just redone whole front of the motor, and resealed the up top stuff, replaced a bunch of things getting perished, new timing belt done, water pump, lower timing cover (Toyota diesel engine runs timing GEARS for the bottom half the motor, and a timing belt from halfway up to the top), new harmonic balancer, fix up the alternator, new thermostat, full swivel hub rebuild, new bearings and seals front and back, steering box rebuild, new battery, and today, it turns out a rear shock has let go, so four new shocks are about to go on order, and that will leave me with after the next run of work, to see if I need to order just a brake caliper re-seal, or if I'll need new pistons in them too. Oh, and I'll finish welding in the new floor sheet metal shortly too. Presently I just want it finished already... But once all the above is done, I still need to fully service diffs, gearbox, transfer, and motor. Then flush and bleed the clutch, and flush and bleed the brakes. But enough about our waffle, back to Duncan's heat problems... I think for Duncan he just gets a thermoswitch, and a manual switch to run some water misters. Thermo so it's only on above certain temps, and the manual switch so it can be turned off even if it is above certain temperatures. IE, switch on for "I'm now on track", then it doesn't need any "smart" computers that might try and do things wrong. And switch the thing off completely on the cool down lap, so when he stops in pits, there's not even a possibility of it dripping any water out to get him in trouble.
