hi all just out of interest has anyone done a 4x4 conversion to a focus st using the original engine if so what parts could be used and how difficult was it to do.
thinking maybe the drive train from the Kuga may fit well or even the original running gear from the volvo S70R to match the engine??

any info greatly appreciated.

Hit the nail on the head with both of your suggestions as far as im aware

TMR

cool wonder if anyone has done it and how straight forward it would certainly be a cracking piece of kit

Have the ST's got same floorpan as Volvo 4x4 C30's?

landaqmabba

not sure but i think so as the C30 uses the focus s platform. There s at least 10 cars that use it it the ford C1 platform???? the kuga and some other volvo s use it too. so my guess would be that it s possible

Didn't the 4x4 rs that was in one of the ford mags use the volvo setup?

Think you'll find Wolf have done this to the new Focus RS already, so should be nearly exactly same for the Focus ST.

Car was featured in Fast Ford a couple or three issues back

TMR

hmmm interesting does the kuga have the 2.5 st engine fitted at all so should be pretty much a case of getting hold of the right brackets and drive train parts. sounds like a good recipe to me

I think it's the wolf one that I was thinking of, white one?

there is a kit that bolts straight in using some couger parts from states but its not cheap other wise every fooker would do it lol

IIRC there was not long after the ST was released a fast ford or performance ford cover car ST with a Haldex AWD conversion.

the wolf conversion is a custom dexler front diff with a transfer box, kuga prop, tank and rear axle. 10k all in and the rear wheels sit 20mm forward. i don't think we will see it done on a st in a hurry.

Volvo V50 T5 AWD, everything should be a straight swap!

James

yes, the kuga does have the 2.5 engine.

Carlos-Titx

10k for the conversion and iirc think it said in the mag that no mods to the floor was needed.

Be good to see one on an ST.

TMR

sounds great suprised not been done then. just need the running gear from a 4x4 kuga then cant imagine it been that hard to do and cant imagine it costing anywhere near 10k for the bits

Carlos-Titx

10k was the cost as a customer i think but it was all done from the parts bin.

landaqmabba

i know it s kind of a dumb question but can you modify the transferbox to get only rear wheel drive (wihout 40% of the power wasted) cause that would be cool having a rwd focus witout cutting everywhere

Carlos-Titx

I would of thought so, the things people achieve with cars these days anything is possible.

As far as I know the mugs and the Volvo are haldex so a bit shit for a performance car

As said above the Kuga drivetrain is used and if I remember correctly they used a drexxler differential.

Very expensive between 10-15k but no reason a budget build cant be done

Only car I can recall is the Wolf 4WD RS

Personally I think you would then need to add more power to compensate for the weight

Can be done but power be 70 front 30 back. Pumabuild offer installation

landaqmabba

but that s shitty... if it was 30 front 70 back it be alright but with 70% on the front with increased power i think you ll get understeer????

what s the standard split on previous 4x4 fords ??? i.e sierra and escorts cossies

even the rs2000 had 40 front 60 rear split if i m not wrong but i just read it on a fan site so not so sure.........

when i was thinking about a 4x4 conversion on my old fiesta i was thinking to the rs2000 box but it s expensive and fragile so people directed me towards the jag x type transfer box and i think it s still 60% on the rear and the gearbox is a 6 speed......... can t the same thing be used for the focus??????

ps. i ended up selling everything as i werecked the fiesta

The polstar volvo c30 used haldex awd and quaife diffs and as seen on top gear had no problems launching in the wet, and seeing as a haldex unit is also used on the veyron then yes not of much use for performance cars .

If you talking about a first gen reactive haldex unit then I would agree your better of with something else, as these require some slip to build up pressure, so not much use of the line which in a fwd is when you need it most, there will be pressure when on the move.

3rd and 4th gen units are instant, pretty sure the kuga uses a 3rd gen of course it will all depends on how the haldex controller is programmed so just using it as is from the kuga may not give the best performance results.
