last weekend, "on a private road area" i decided to see how well these skylines do circle work, i found out, they do it quite easily.

i even started it in 2nd gear, surpised me how fast it whipped around actually.

any way the point of this post, it open wheeled for about 3 metres on the 2nd donut,

the diff seems healthy, but i wouldnt mind making it a bit tighter,

should i just go to nissan and buy some shims to tighten it up?

or is there something else i have to/should do?

cheers people.

The beginning of the end.

Its a viscous diff not a great deal can be done apart from shim it which sort of works but with mine it would still single leg in a straight line; out of corners etc it would twin nicely.

If you are going to have the car making some decent power spend 1k and throw a good new mechanical in it.

a grand on a new diff?? im not going to be a pro drifter mate. lol

i dont really wanna lock it, its too dangerouse....

i might just shim it tight, and see how i go, if it does do commodore style single leggers when i launch, i will definately start looking at a brand new item, prob go a mechanical two way, make it more interesting. and do it right the first time i suppsose.

Nothing about being a pro drifter its just what a new diff is worth. And there's no other option apart from dodgy shimming which induces understeer and in my opinion made the car feel shit. Especially pushing in to round abouts.

Mine was tight enough to always chirp the inside wheel through corners but on hard acceleration it would still single leg.

Spend more $$ on tyres and i guess you don't have to worry about it single legging as much :)

I wouldn't go a 2 way. 1.5way for street etc.

spend more money on tyres? geez, i paid 260 ea for my 18s, and i thought that was dear!

i think i will just look into a new diff, i want it to be streetable, i have driven a car with a mini-spool, and your right, it does feel like poo.

ill finish this one off first though.

come on race track! hurry up and open!!!!!!

:) $260ea for your 18's eh? Try over $450ea for my car :(

Seriously though, I'd definately go for the new diff option too, like Cubes said shimming the diff does make the car feel rather pooey, especially in round-abouts; that's just my experience however. You don't need it at the moment, so I'd just put $100 or so away every pay and before too long, bam, new diff :D

450??? fark! youd be scared to chirp them? every chirpie would cost you bout 15 bucks! lol

ha ha im already saving for a new turbo and fuel pump....

ill need to start selling myself on hindly street soon lol

point taken though, cheers guys

i wouldnt call it a disease, but more of an addiction lol,

i wasnt going to spend a penny on it when i first got her a month or so ago......hmmmm 3 grand later, i still have more to go.

im sure everyone else on here is the same too, but hey, atleast we all have something to be proud of.

If ya down south, go poke ya head in and speak to Graham at Boss Differentials (Listed as Boss Automotive in the phonebook - Scarbourough Way Lonsdale)

He does all kinds of diff centres and diff work, and can suss it out and tell you how much ya looking at. He's also a seller for KAAZ mechanical diffs.

Service is second to none, and he's always willing to offer straight down the line advice. He has built many an old schooler diff, race cars, maintains god knows how many drifter's 31 diffs hahahaha, and tons of street cars

He'll be able to give ya an idea of the best diff centre for ya application and not let ya spend heaps of $$$ on something ya might not need

I had a small bad experience with boss.. :blink:

I think he was in a rush and simply shimmed my s/h purchsed lsd.. preload was tight but there was a couple of smashed disks in there that he didn't notice. So wasted a bit of money with both the purchase and shimming of the s/h diff. :blink:

yea champ, they cost alot of cash but i figure, money is money, it comes and goes whatever you spend it on, if its something you love and get enjoyment out of then its all worth it.

    • Ok interesting i guess ill wait till using a manual gauge before making assumptions.
    • Not in any way a logical conclusion. Also, looking at those logs, I struggle to see how that much oil pressure can go away that fast unless you are sucking air into the pickup. Meanwhile the ECU voltage is chucking a huge wobbly which seems to be tied to the throttle position. 100% throttle results in decreasing voltage. It's a mess.
    • So didn't get around to installing a manual oil pressure gauge and then decided to take the car for a cruisey drive to a cars and coffee and brought the laptop along with to get another log using more gears to see if its an oil pressure issue under acceleration or after. this log has 3 gears of WOT where as previous had 2 and the oil pressure dropped once on the brakes, and the same again happens here which is interesting as it shows it can hold oil pressure while under acceleration but once slowing or just the lower RPM after a pull pressure drops. I will be chucking a manual oil pressure gauge on to confirm but so far this makes me feel it is not an electrical issue. Something else i realised is the pressure sensor also is giving temperature information and the temp stays steady the whole time which makes me feel like the sensor itself is showing a true pressure reading.
    • LOL.... fk...   there goes 25K to make 200kW
    • For sure the later RB26 variants had a different setup (6 cam voltage sender?), but the RB25DE/DET share the same ECU pinout/PCB footprint, and at the ECU plug it ends up being 'throttle sensor in' & 'throttle sensor out' (to A/T TCU) ...you stick a multimeter on these pins and you'll find them directly connected (0 ohms) ; I had an pair of Nissan ECUs on the bench long ago, and I noticed this throttle sensor in/out link, actually linked to an op-amp ...which was unpopulated on the NA board, but present on the T board and I went 'ah-ha!' in some moment of clarity... ...it wouldn't surprise me if they changed strategy here though (in the software and actual monitoring of this signal), because they did with other stuff (A/T signals).. and 0.45v as a trigger point makes sense, as that's what the external TCU units expect at idle ; kudos, thanks for that insight...I suppose it boils down to whether or not Consult can display real time data of that signal's voltage... ...in any event, it presents the same target...ie; rotate TPS unit to achieve 0.45v to suit both ECU&TCU, and where do you goto from there? Just disconnect TPSwitch connector and/or that plus TPSensor connector....or do you go for the throat and disconnect IACV solenoid and see if it still stalls? (probably throws a recoverable fault code and goes for default idle strategy?)...
