Given my diff is a single spinner, what sort of dollars are we talking to convert it to LSD? (Factory LSD or upgrade to TruTrack)
??

I thought all V8's since the intro of the LS engines had LSD from factory.
I have 3 freinds with LS1's, a VT2 exec, a VY Berlina and a WL statesman and they are all factory stock and all have LS diffs, all bought 2nd hand so not sure if they were optioned up when new.
Also as Wonky said keep an eye out at wreckers and ebay for 2nd hand LSD's.
My mate with the WL found a 3.46 a few years ago for $450 off ebay from a local Sydney wrecker and it has been fine, and sold the LS 3.07 diff for $300 to a kid with a sigle pegger V6.

Mine only leaves one black line

SS and SSV VE's get LSD as standard, Calais and CalaisV are options.

What's the go with a trutrack? Could I buy one and put it in my current diff or is there more to it? Price?

Its a completely new centre. So yes you could put one in yours. They are awesome. Make a normal LSD look absolutely stupid.

[Drizt]

Cool. Sounds like a winner.

So I could probably spend $600 to $700 and get a second hand holden lsd with any ratio is want or I could put in a trutrack at $2000 and keep the standard ratio. Or a combination of the two.

Anyone got a link / diagram that shows all the parts in the diff?

Keep in mind the LSD will only work for a Limited time

The TrueTrac will work pretty much forever if you keep clean Oil in it!

Have to agree with that, I replaced an LSD with a Truetrac (in a non LS car) and the cars behaviour was much more predictable, the LSD would spin one then the other, sometime both, the truetrac was both all the time, you knew exactly how the car was going to behave when provoked.

Thanks for all the help guys. I believe I have now locked down the order of my TODO list.

Mind you, I might never get past the OTR on the list.



Cat back - Done (might update this later on though)
Tune - Will talk to Chev's in a month or so about getting a tune (auto tune as well).
TruTrack - Probably keep the current gears.
OTR (and touch up tune)
extractors / cats (and touch up tune) - might update the catback at the same time, will have to wait and see.
Coil overs
Breaks
Sound system etc.
etc

[Drizt]

Ok, well it took a bit more time than I expected but I have contacted Chev about getting a service and tune done. I look forward to seeing what the results are

My old vy calais i did on a budget everything secondhand except chevs tune and valve springs made 242rwkw from tri y into 2.5" hm cat back, alloy otr i got off ebay, underdrive pully and valve springs rest of car stock made it fun to drive should of kept it all up just over 2k

[cjf]

My thoughts for bang for buck on a budget.

1) Exhaust - Catback
2) Diff gears - LSD
3) OTR + tune.

if $$$ permit also do these before a tune.

4) Cam /lifters/valve springs.
5) Trutrac

if auto don't even bother with a Hi stall worst bang for buck in a street driven car IMHO,
Only any good for drags, the stall has made my car a real pain to drive around town.

Really? What stally have you got cjf? Brand, lockup etc etc...

I agree, must have got a very loose converter. Driven bolt on and cammed cars with tight 3500-4500 converters and they drive like stock while still reeling off 1.5-1.6 60 footers. If you're serious about racing, its a necessity but as long as you pick the right one, you won't sacrifice drivability for it.

Chris I had a new converter built for my car setup by Dominator (4500 lockup)and put it in earlier this year. Strongly considering removing it and refitting stock converter.
