9" Diff Centre To Suit Independant Rear End.

[BezerkR32]

Hi guys. Have heard you can get 9" diff centres to suit R32 and billet shafts. Just wanted to know if anybody has fitted one and where to get them from. Any help would be appreciated.

Not much help but they do make em.

Were any XE or XF Falcons IRS?

Nope, no Falcons were IRS until the AU

You can setup a nine inch for IRS, but I don't think its worth all the cost and trouble (especially making the CV's).

If you are making the big power, then build the real racing rear (4 link live axle).

[T04GTR]

why would you want to do that?

if you want a diff wich is much stronger just use a z32 tt diff.

r220. 220mm vs 9 inch 228mm.

it will bolt up using gts4 driveshafts and WONT BREAK. not sure about the axels but.

[2rismo]

Hmmm.... Z32 R220 with standard gts4 axels or braced 9" with billet axles.

Tough decisions...

how much power are you running?

r200 diff's and r32 driveshafts/tailshafts have a reputation for handling as much power as you can throw at it.... 9 inch conversions are very uncommon because the stock diff is strong enough...

[discopotato03]

Sounds about right Merlin , IRS 9" based diffs were used in Grp A Cosworth Sierras but doubt very much there was anything Ford about them .

Cheers A .

Stuart's car will make a shitload more power and torque than my car and I explode CV's and snap axles 2 at a time with 265kW.

R33 GTST R200 LSD's and std axles = Rubbish in my opinion. The only reason people say they're 'strong enough' is because 99.9999999% of Skyline drivers ESPECIALLY the ones with big HP cars NEVER race their cars hard. They're all soft - especially the GTR drivers

well, that's why i asked how much power he was running.

As you said... They are strong enough for 99.9999999% of skyline drivers.

oh, im sorry. lets see. a diff that bolts up.? or a bulky 1950's based bigger is better truck diff? not that theres anything wrong with them. just try finding one that has a nodular iron case and doesnt use a floating inner axle design.

il choose the r220 and perhaps using shortened r33gtr 31spline axles. hks and pretty much any other 1000hp drag gtr seems to do ok

worst case just get some "billit axles made to suit the diff that fits? or you could try and cut n shut a 9 inch.

but... if you were seriouse you could probably convert the car to a 4 link set up. that would work best. and the nine inch will be very well suited

TRP's R32 ran mid 9's off transbrake with an s15 centre and gtr driveshafts, don't know how much faster you want to go.

[Dahtone Racing]

whats a 4 link set up worth?

It's got nothing to do with being serious or not. It comes down to what you can do in the class you want to race in.

Thanks for all the info guys, i am running the car in Oz so 4 link is out and dont have spare 10k to throw at it. I have the R32 GTR diff and shafts fitted, sound like they may be up to it, ill just put a mechanical centre in once i know what gear ratio i want. TRPs R32 skyline has given me some faith.

Wise move Stewie...no point trying to re-invent the wheel
