engine mounts normally cause that shaft issue..
re the xr4x4 shafts,i cant use them in mine,as it judders like hell when cornering,just not enough movement left in the joint imo,and i know plenty have had the same problem.
reco prop do make a shaft 10mm longer,which is a good answer,the rally guys used them,so they told me.the bare shaft is 130quid ish each.

settle down there!!! this is a ROAD car we are talking about here, hence a dog box will be horrid for normal use, so in that way he is limited to MT75 upgrades to keep it reasonable. Yes I'm sure you can have an FFD 6 speed, but at 7k it is over twice the price of a Bara box, and then you still have the rest of the transmission to do... I am not saying what I suggested was the be-all and end all of upgrades, just the most reasonable IN MY OPINION for the use it will get Vs Cost Vs reliability.....
Why don't you run a full works car in your Rallys??? COST
...
As regards to the xr 4x4 shaft debate, I have run them with no problems, as have friends, one who went through about 5 std cossie shafts until he fitted an xr 4x4 one that has been fine ever since.. Every man and his dog knows they are an option for getting rid of the ripped out shaft problem, look through any magazine article on the 4x4 cos and you will find it says an xr 4x4 shaft cures the problems of a low car??
... It might be more critical on a gravel car with the longer suspension travel, I don't know, but I am only saying that this bit of advice has been around for years, and It has worked fine for me .....
9" diffs in 3.64 ratio?? PM me a price for 2 please

PassionFord Post Whore!!
yeah i'm going to go for new mounts when it goes back on the road, i don't reckon the 120bhp monster requires collins mounts or even if they will fit but hopefully standard new mounts will surfice!

check prices first!not much difference iirc
uprated mounts also help reduce the engine movement,which prevents shaft popping out,not 100% but pretty sure they allow the engine to sit a tad lower in the bay,to keep the shafts straighter....aswell as replacing the std ones which WILL be split! jack under sump,and they seperate....
ive never broken a std length shaft with uprated mounts at 380bhp,where as with std mounts and 330 bhp it was weekly!

something i will most definatly have to look into then, they always seem to break when on left lock and accelerating/when i'm dicking around, so fully expect its the engine mounts ultimatly causing grief!
don't know if anyone does uprated twic cam xr mounts though!

mmm,vibratech might,thats the ones ive got.
cossie ones might fit
just stick a jack under the sump,block of wood on it,take it up,and normally the mount is in 2 bits,the bolt part pulls out with half the rubber on it! not good,as the engine then lifts under load,hence shaft pops out.

Now he uses 3,9diffs same procedure.
and box is fixit, so standard will last just fine.
Just funny that nobody seem to trust me on this LOL
Have NEVER broken a diff in mine, in 80k km and i use it HARD!
The right clutch will get the (standard)gearbox to last tho.
BUT only one solution if u want a bullit proof gearbox and that is the skyline gearbox, non of the ford ones will last, just a matter of time before they break

i use xr shafts and vibratechnic mounts, no problems what so ever
though i havnt gave it a proper full launch yet as i like my gearbox and diffs lol
once these are sorted il give it ago, im also going to be going the skyline route as soon as my box gets destroyed, though im not running as much power as yours yet, im running around 380 -400 but the engine is built for 500, so only a matter of time to get the full potential out of it

I'm not sure if its a std box?? IIRC its a OS griken gearkit inside a std r32 box. Just speak to martin...I'm sure he will sort a good price for you

wake up please, as for the why dont i run a full works car - well i was going to buy a full works car so cost is not an option, but i wanted it to be better - so weve taken a lot of the best works stuff and made some of it better than it was in 1994(it was 14 years ago !) and are building it to be even better - and no, i havent won the lottery, you would be surprised how much cheaper to maintain a well built car is, i.e no cheap gearbox every 10 mins, by the time youve fitted 5 boxes and 10 diffs you could have bought half decent stuff anyway - as for the diffs- if your serious and have around 6k(ish) to spend pm me.

Mark Why can he not have 600 bhp in a road car? it does not have to be driven flat out like a rally car?

so 6k ish isn't just under 3k a diff then? Like I said in the first place. But to be fair, both you and tim live and breath rallying, you have to remember whilst you are right in essence about spending 15k on transmission, 99% of people cannot/ don't want to spend that sort of cash on it.
Please don't take this as falling out/ angry post, just an honest opinion
I respect your experience and Tims, just hard for you to see it from a normal car owner type of perspective.

I respect your experience and Tims, just hard for you to see it from a normal car owner type of perspective.i wont fall out with you mate, i just find it so hard to understand mega hp road cars thet break when you use them - i gave up fast road cars about 12 years ago, ive now got the fastetst road car ive had since i sold my stg 3 sapphire 12 years ago - and its a fucking diesal mate
even the wife snapped a driveshaft on it ! 
so would you be interested in the diffs at 3k each ?

amrtin isn't the only one to do a skyline box conversion... there was an escos in fast ford or performance ford a while back with one!
also, see here for a home made one on a 24v cossie:

i havent read all of this thread but its prob the same crap as usual, people saying you can use standard diffs etc
budget for 15-20k for transmission and you will have someting fairly reliable, ie FFD 6 or 7 speed. 9" rear diff, all original diveshafts chucked in bin and very minimum of being replaced with brand new units,HD props, thickwall front diffs well i broke one of them and changed to R+D which seemed ok for what i was doing.....
its a fooking money pit and you have been sucked in
