Here is the reply I received earlier today:

Hello Jorge,

is this older diff compatible with the newer transmissions? I don't see why we wouldn't be able to make this, but it would most certainly be more expensive than a typical front lsd due to the addition of the extra center gears as well as the shaft(s).

how much are the TRD and TTE ones mentioned in the forum?

Thanks,

Stephen


Based on the link CMS-GT4 posted, I'm assuming the diffs are the same between the generations with the exception of the extra components for the diff lock mechanism or the Viscous coupler. I don't know very much about the TTE/TRD diffs mentioned but I'm under the impression that they were limited production parts made many moons ago and no longer available new. Any more information/input would be appreciated and very helpful in getting this unit into production.

If you guys know of any other parties that may be interested in this or very familiar with the workings of our transmissions please point them in this direction so their voice can be heard.

Thanks again!

The gearbox that is slowly making its way into my rallycar was built by the guy who used to build them for the factory team when they ran Paris-Dakar. He said with enough effort and money things could be machined and massaged enough to fit an mr2 lsd in place of the open front diff. Since I pretty much ran outta budget, I kept the open diff. I can try to get particulars on whatall needs doing from the guy, if there's interest.

Fitting the mr2 lsd as a front dif has been a rumor for a long time. If you could find details we would appreciate it.

...and may continue to be. I asked Robert what the specifics were on this option and he said vaguely that it would involve machining so much of the case out that he worried about weakening it. I guess we're back to hoping this outfit makes a drop in setup.

More correspondence with Stephan at M-Factory

Hi Stephen,

I've been reading up a bit and can't seem to find any info on pricing for the TTE/TRD units. They're obsolete so I guess they go for whatever the seller can get these days if one ever becomes available.

The diff appears to be the same from what I've read and heard with the exception of the extra outer ring. I'm working on getting my hands on a viscous center section and related components from a newer generation transmission to send to you if you are interested in checking them out.

What sort of price range do you think something like this would fall under? assuming both a front and center lsd type diff is made. How many people would you need on board?

Thanks,
Jorge


His reply was:

Hello Jorge,

we would require the minimum 10 units. For price, it's really hard to say, but we should be able to keep it under $1k.

Thanks,

Stephen


That said, I'm currently looking to get my hands on an ST205 diff assembly (assuming this is the best starting point) to send to M-factory for measurements. Once that's in hand we can get the ball rolling. Does anyone have one they wish to loan out for a good cause or sell for a reasonable price?

Honestly, you could get any of the diff units for measurements since they are all basically the same and function on the same principal. All open front, viscous coupling center.

You wouldn't happen to know of any floating around, would you? What would need to be changed to an ST165 unit for it to work in a 185 or 205 trans?

good luck with the GB jorge, i can say for sure that mfactory makes some excellent products. i still have one of the prototype diffs kicking around from the group buy i ran, if anyone would like some close up pictures of their work.

i recently converted my escort to an E153 trans from a camry... if only the timing were better i most definitely would have put an MFactory diff in there. they must be a recent addition to their catalog, because they didnt have them available back in october when i purchased my Quaife. unfortunately my timeline was too short to be able to organize another group buy at that time :(

I know sometimes 185 gearboxes are listed here for cheap or free. I would just post a WTB in the FS section and look through some of the threads to see if some are still available.

Found one! Waiting on a shipping quote. I should have it in hand by weeks end then it's off to M-Factory for measuring and then pricing/group buy requirements.

Just a reminder, all payments and shipment will be handled directly by the manufacturer (M-Factory).

Too bad I didn't see this earlier... I have the front/center diff and transfer case assembly from my old FWD converted ST205 box sitting on a shelf in my garage.

PM me if I can be of any help here...
