HAldex Rear Diff with Standard Rod change box

[CR500 Dom]

Is this possible ?

I think I have a problem with the new Syncro`s rear Diff or VC, but its a bit difficult to Diagnose at the moment as I am in UK and Car is in the French Alps []
I am just trying to think ahead for when teh car comes back

Is the Haldex conversion ok to use with the standard set up up front ?
I am wanting to sort the rear section out (Using Mechanical controller) for now as the power upgrade wont be enough at present to stress the Gearbox and require a change to Cable shift…

Is this possible ? or are the ratios all wrong ?

Or what are my options in terms of rebuilding the standard VC or adapting another kind of Centre diff/VC instead ?
Thanks in advance
Dom

What Syncro do you have? Motor code, BHP etc please.

As said many times before the 020 rod change box is good for up to 150 bhp while the 02C cable change will handle over 200 bhp or up to 300bhp when fitted with a diff bolt kit.

Both the Golf & Passat fitted with 020 & 02C gearboxes use basically the same rear diff & VC unit so there is really no need to go Haldex untill you have more than a couple of hundred horses under your right foot.

The Haldex ratio is not compatable with the rod change transfer box, whereabouts in the Alps is the car, give me a shout when you find out what you need as I have all sorts of rear axle & differential stuff here

the rod change will handle more with the diff pin kit

either that or im buggered!

Just put another rear diff & VC in it there pretty easy to get hold of and not exactly expensive, last count had about 3 in the shed,
the gearbox sounds like its maybe where issues develop, out of interest what motor is going in ?

The bolt kit dosent really let it take more power, in short term it does stop the diff flying through the side of the bellhousing at some random point.

Issues I found were 210 mm clutches don’t last very long if you drive hard, if I pulled off hard quite often it’d slip.

Other problems are the main shaft and 5th gear, 5th is a bit weak on all 020 boxes but syncros can also munch the shaft itself by the clutch, this seems to happen when using aftermarket uprated clutch instead of oem items.

For the box to take more power maybe take the guts from a mk3 box that’ll give you a bigger shafts and let you use a mk3 diesel clutch. that’d take fair bit more stick methinks.
