No. The Quaife is constructed completely differently. It's the actual guts of the LSd that are stronger, not jsut the ring gear and pins.

Figured as much. Thanks!
Actually they're not that expensive for an Evo.. TRE rebuilds Evo transmissions for WAY less than 5k..
There's 2-3 shops putting out built autos for our rides

You mentioned more?

this is a re-build of a focus, but they use the same tranny we do.

I thought welded differentials were for ricers with no money for real parts? (flame)
why not swap out to a stronger gearbox with an adapter plate? something off the side of a honda K series motor - or a toyota gearbox.
An engineer should have no trouble making an adapter plate - you'd probably need custom shafts and so on, but you'd end up with something fairly bullet proof.
I've seen and heard of the results of hardening the G series trans, and everytime you strengthen one thing, something else breaks.... its a constant battle.... all the money poured into trying to harden something that seems to always want to break could be put into converting the tranmission over to something which is more suited to taking alot of horse power....

Good idea...didn't know you could do that. I heard from a good source that the forks inside a Mazda3 are very similar to the Protege trannies but importantly are thicker and can be made to work with a little work. In the end though...our trannies are garbage. I've been through 3 in 2 years(drive2).
every attempt at hardening hte box i've heard about has ended in tears. I've even heard of extensive bearing mods to try and stop shaft flex, resulting in cataclysmic failure of the entire gearbox.
Best to not use anything mazda
swapping to foreign gearboxes is an old school hot rod technique... they'll often strap GM gearboxes to ford motors, etc. In theory, its the same for a transaxle.
you need an adapter plate which bolts to the block, and allows the box to bolt to the adapter... you'll need custom drive shafts to get the spines all right and so forth, and you'll need to do something with your shifter (if going to cable shifter, its easy....solid you'd need some modding) - then theres the flywheel, clutch, starter, gearbox side engine mount etc...and probably a handful of other bits and pieces i haven't thought about that need to be customised or modified - but the point is, it can be done, and it would probably be cheaper than building a G series only to have it blow up and force you to build another one.
It also opens up a whole range of possibilities for gears - Liberties make honda gear sets which are tough as nails, and theres probably a half a dozen diffs to chose from - as well as the prospect of nicer gear ratios etc.

you should look into this and get something going!
Actually, its not that hard to look into it yourself
start by ringing up some hot rod shops, and see if they will assist in creating a "gearbox adapter plate/ring" for a transaxle gearbox.
Then you need to research a transmission that is tough as nails. Theres a guy in australia with a BPT powered mazda famillia wagon who runs a toyota MR2 turbo gearbox in his car....its 5th gear is as thick as our first gears
Then you'll need to speak to an engineer about the drive line modifications that will need to be done...
it really needn't be that hard, but it would certainly be more difficult than just making an adapter ring - which is why you're not going to find any "kits" in the near future
Adapting another manufacturer's tranny really isn't that difficult, just takes some know how as LordWorm has stated. The main problem is people want a cheap solution. Most people don't want to spend 3K+, but its going to take that kind of money to have a reliable gearbox that can handle decent power.
If the sub 300whp World Challenge cars couldn't keep a Mazda tranny together, chances are most people can't afford to keep a daily driven Mazda tranny alive.
Used Xtracs are available for around 7K USD I hear

yeah, xtrac is overkill though (and probably not nice to drive as a daily!)
Best bet is something honda (because of the aftermarket gear support, probably the best bet), or toyota (bullet proof, tough as nails will put up with more HP than you are likely to get out of a FSDE running pump gas), but there may be others.....
Thing is that i cant understand, is people wont spend the money on a box conversion, but will happilly kill 2 or 3 or 4 gearboxes, that all have mods to make them stronger - the total amount spent on the g-series boxes would easilly surpass the one off cost of converting to something you wont ever need to worry about, and even if it did go bung has far more after market support and is far cheaper to keep going.....
