If your getting traction once the tyres warm up then it might be worth trying some different tyres that will work when cold. I've got 265KW and use federal 595SS and they hold traction really well, well in the dry anyway. i've put some different tyres on the back before and it was nothing but wheelspin. Other than that you could run less boost or get a tuner to adjust the tune so you get more traction in the top end which sounds lame (less power) but it will work out to be quicker than wheelspin.

Yeah it becomes an expensive exercise changing tyres...!

I think i'd like to try the ABS signal -> Haltech torque reduction feature... sounds pretty neat.

When the car was on the dyno for an E50 tune, after a few runs the things were like glue. But even spinning them like mad all the way to work (10kms) when i get there they certainly ain't sticky... they cost me $600 a pop and i spent AGES researching and heard rave reviews but perhaps they were more track oriented...? :ermm:

Yeah sounds like they are more track oriented. KU36s can be had for $240-280 even for wide rears. Its important to work out what driving you do and what tyres suit best. I just went through that recently and I mostly either just commute and occasionally have a quick squirt so I need the tyres up to temp quick and doesnt matter if they get hot after 3-4 laps as I dont do anything like that. I can spend more to get better track performance and wet weather performance but I dont drive hard in the wet anyway either.

Dont throw your current tyres out just wait till they are stuffed. At the rate you are wheelspinning it shouldnt be too long haha

Go for a drive and if you lay 2 lines then dont worry about the diff. A good diff is more for getting the power down earlier out of corners but generally you sacrifice noise and shuddering etc. Your complaint of wheelspin in a straight line is not going to be solved by a diff if its already turning both wheels.

I had a Cusco diff... was the one with the springs in it to lessen the clunking/banging... it was still noisy and would shudder sometimes but well worth it to get the car handling properly IMO

Im not sure if its the same story but I swapped out my whole rear cradle for a GTR one, mines a R33 GTS-T though.

Much better hook up, no more open wheeling, and the axles/half shafts are bigger as well.

The whole swap cost less than a new aftermarket center.

Joey,

What positive changes did you see in performance when you put in a 1.5LSD?

My cars pretty violent in the first few gears and nothing short of soft. Running 275/19 NT05s and considering downgrading to 18s and slapping on some NT05R Drag Radials. Its making close to 300kw @ 4000rpm so its very on song. Traction is a bit of a issue these days

Would you recommend upgrading to a 1.5?

What setup have you got that's making 300 by 4k rpm? Traction would be an issue with that i'm sure! My 300 (on E50) is not up til 5.5k rpm.

But if your diff is gone then you will still get wheelspin when your expensive tyre is heated up. But you dont, therefore it would seem getting some tyres that get up to temp quickly is your first avenue.

Agreed. Just thinking of down the track when this car doesn't see the public roads anymore...

Yup gotcha, there is definitely place for a nice diff just didnt want to see you doing it to chase this issue.

the car hooks up instantly every time and goes IN A STRAIGHT LINE when the wheels spin ;)

for a car with that much power dont go the TT model tho, just get the normal model and deal with the noise :)

what do you use the car for?

yeh i notice mine always kicks out to the drivers side ALL the time.

The cars a street drag car. Custom drag suspension and all that. No sideways action at all.

seriously considering a LSD but i think some Drag radials should be next

i'd probably look at a nismo/kaaz 2 way then.... it's an absolutely amazing upgrade for a car, but if you're going to go drag radials, dont get the tt... just get the noisiest, clunkiest strongest one you can ;)

if your car is crabwalking you aren't putting down all your power, so it's just a waste :)

      As I've said elsewhere, I am using the stock intercooler piping path in the engine bay, and a return flow cooler, and making ~250 rwkW (without any effort put into trying to turn it up past there just yet) and expect to be able to make some more, and frankly, I would be perfectly happy with 260-270rwKW. This is peak road Skyline usability territory. You go past there and, sure, the car will snap necks more when it's on boost, but it will also break shit all the time, cost a (even larger) fortune in tyres, etc etc. Anyway, I also do not like the over-the-fan pipe path, and you don't have to do it.

      I see, honestly I’m not too fussed about the looks. The only reason to go plenum is to make the piping easier instead of the classic over the rad etc.

      Not easy to quantify wrt something like how many fractions of a second slower it would be over 0-100. But given that a 250-300rwkW car is able to do that launch sprint in 5-6 sec (and faster with appropriate tyres, and surface)..... giving up as much as a second would feel like torture. A ~450HP capable turbo is not going to make lots of boost in the 2000-3000 rpm range. So, whilst with some boost on hand it will be faster accelerating in that rev range than your engine currently is NA, it will not feel like a fast car until the boost is solidly in. You know what your car feels like right now when you open it up at 2000rpm. if you've ever been in an actual fast car, you will appreciate that the NARB25 is.... not exciting. Well, add some boost and it will be better. But shorten the intake runners and it might not be better at all. It might come out better, but it could end up feeling the same. For me, it's not the 0-X km/h sprints that matter. It is easy to fry the tyres with anything over 200 rwkW. You can't use all the power available in 1st and 2nd anyway, you have to modulate the throttle. What matters is how the car reacts when you're driving in traffic in 4th or 5th and have maybe 2000 rpm on board, and you want/need to add some speed quickly, and don't have time for the downshift. It won't make boost, it will be all NA (at the speeds we're talking about - remember how fast you're going at 2000 in 4th! and don't plan on breaking the limit by too much.) So giving away NA torque is not what I would consider practical for a street car. And retaining that NA torque builds boost faster which makes the car faster. The flashy plenum is not actually better, unless you're looking at a track car where you can keep it on the boil all the time.

      So how much difference does it make you think? Like 1 second in the 0-100?  I was have smaller turbo so hopefully that spools quick GTX2871.  currently it’s NA so you can imagine pretty slow, but I do want fast accusation a little as there’s not many places I’ll be driving where I go over 80 even near me. So 0-60 and 0-80 targets
