4x4 cossie
o degree XE pattern
How long will they be mate? could do with mocking my engine and gearbox im my car. Cheers
I will have a text plate by the end of the week hopefull so once the changes are made so it is perfect i will run some finished batch off b
Looks like i will be making one to fit the 2wd flywheel too.........
funny ho the the starter motor hole seems the same but the bolt holes differ
The 4x4 and pinto starter are the same. The 2wd starter has a different hole pattern on the starter motor too.funny ho the the starter motor hole seems the same but the bolt holes differ
the vauxhall test plate all cut
and the final draft of the 4x4 cossie plates are done (limited numbers of 3 as a trial to see if they sell)
I saw a couple of ads on ebay the other ay for Vaux XE ones, is it you thats selling them?
All Cossie bolt paterns are the same as a pinto are they not?

The 6 engine block mounting holes are the same, the starter mounting holes seem to be different between 2wd and 4wd. It must be down to using the 4 x 4 gearbox and flywheel etc
My vauxhall ones aren't finished yet they are still in the test period at the moment. They will be ready with in a week or two.
The cossie block is obviously the same. The start holes are the same pitch as the type 9 pinto starter on the 4x4 but futher out for the bigger flywheel. The 2wd starter has a different starter hole pitch and is in a different possition yet again to the 4x4 starter.
What you said.The 6 engine block mounting holes are the same, the starter mounting holes seem to be different between 2wd and 4wd. It must be down to using the 4 x 4 gearbox and flywheel etc
Nearly there now!
I hope you have your plate as it looks like someone is selling old stock off cheap. ;P
Let me know when the xe one is complete mate and ill get the money over to you.
Cheers
does the rx8 5/6 speed box cope with cossie power or is the rx7 the one to use,and is the same adaptor used
that is the big debate no one seems to be able to answer. I will be going sensible cossy power so hopefully it will be ok.

duraescort on the other thread reckoned the rx7 5speed was good for 450 so would that one not be best for a cos install,is the rx7 5speed the same as the rx8 5speed?
Rx7 is the obne that handles big power.
There are more than one jap box that will handle huge power
The point about the rx8 is that it CAN BE FITTED to a ford engine. At reasonable cost in uk
BMW M3 box is a popular conversion for cosworths.
maybe, but still got a rubbish 1st gear lol!
Not so much for a cossie with a high final drive, i reckon Gertrag boxes are the best production boxes out there.
I've broke one with abit of power think there's gonna be disappointed people soon they don't seem to be able to take the torque , maybe rx7 is the one to have , was told by power torque the mt82 transit rwd box will fit on to duratec and can take loads of power just a shit first gear if anyone looking for gearbox for high power duratec
What power do you have?
You have said you have broken one in a previos post but when i asked you never said how much power you are running. It would be interesting to know what car you are running one in with what engine and what sort of tyres you have.
Other news is i have fitted up the XE plates to an engine and they are cock on. I have a couple of hole sizes to change but apart from that it is spot on.
If you look back I replied it's a 2.5 turbo duratec running 335 Hp at wheels 299lbs feet it's broke a n7 Mazda gearbox 5 speed , and the 6 speed one then went on to rx8 box after all the hype about it bought adaptor plate off the founder of them , it lasted 3 weeks about 130 miles , 215/45/13 tyres all way round
It's in a mk2 escort by the way
What did you break about it? Not the input shaft bearing by any chance?
Road going tyres or slicks too.
No it broke teeth off
Khumo v700 tyres
Once the box is bolted up and in car what mods are required to the prop shaft if you have your old t9 one and a Mazda one
I had my escort prop shortened 2" and the end changed to an rx8 one by BAR Props ine Neath, South Wales. They do a brilliant job.
Broke the teeth off of what? The gears? If so what gear? Was it the gears on the end of the input shaft? Your not very forth coming with information considering your trying to help people out.
Dont know when I drained oil out to remove it 6 teeth came out haven't stripped the box yet but it lost 2nd and 4 th
I struggle to see how these boxes could be that strong, the engine they are intended for produce very little torque, why would Mazda go to the expense of over engineering a mass produced part. An Rx8 produces 156 lb/ft at 5500 rpm, thats the same as my Pinto at slightly higher revs, why would an RX8 need a strong box?, its close ratio to keep a small light engine spinning, thats the only benefit i can see.
Interesting. Keep us updated when you strip the box. My fear is that the old style plates didn't line the input shaft up properly which would lead to the input shaft bearing failing or the teeth on the input shaft breaking off. I haven't heard from anyone apart from yourself breaking one of these gearboxes yet even with the poorly made adaptor plates.
We have to push the boundries in life and this time it is to see what these gearboxes can do. If we all denided everything before we tried it like you are doing nothing would be tested and it would all struggle to see what could be done. These base boxes are also on the back of an s2000 and people turbo and supercharge them with out box issues.
All i can safely say is it suits my needs as i have given this box a hammering and i would imagine there are many more people who will be running high torque high reving n/a engines that will suit this gearbox better than the type 9.

Honda S2000 makes around the same low torque. Most folk that are rallying with high revving NA engines run dog boxes, for me its the only way to go if your running decent torque and don't want the synchro reliability issues, a helical cut gear will always be stronger than a straight but synchro's will always be a weak point in any gearbox.
