any chance this MSP LSD would work in the 1.9 case?
I dunno, I've never had a 1.9 case open myself, and wasn't paying attention to the diff really when my buddy's toasted itself. I only got to his house in time to help him put it back together. I can take measurements of a diff that's out, if you've got a 1.9 diff around, and we can see if the physical dimensions would be close. Probably have to end up getting different bearings though.
In fact, that just reminded me, no, I don't think they will work. I think the 1.9 one is a significantly smaller diameter, at least when the two speedo gear sending units are measured. the 1.9 speedo gear assembly is about an inch longer than the 1.8 one. this indicates a smaller diameter speedo gear on the diff, or else a bigger case.
can't hurt, to measure it up, though.
a Definite change when turning under power:
Before, when under a good amount of power when turning, it would always be pushing just a little, the outside front corner would be down and the inside wheel would spin.
Now, it doesn't really push, because the outside wheel has traction and literally pulls you through where you want to go. The outside corner goes down even with the inside one when braking, but when power is applied, the car sort of levels out into a more neutral attitude. It's a frickin' AWESOME feeling. Just like when I drove my buddy's 88 crx w/ B16A, and my other buddy's 95 civic hatch with an ITR drivetrain.
It goes where you point it better, and it also seems to straighten itself out better too when straightening out after the corner, like it's got some major caster. But, that might be just because I've been driving my Volvo (RWD) since November, and am not used to the tightness of my wagon anymore.
Now, instead of having to pay as much attention to throttle modulation to avoid losing front wheel traction in the corners, I've got to pay more attention to making sure the car is settled, so I don't end up getting the back end too loose.
I am SO driving to the other side of Wisconsin to check this out....when are you racin next?
Also, did you rebuild the tranny at the same time? If so, where did you get your parts? Did you upgrade to the Zx2 gears?
the only thing you can rebuild are synchro's and bearings.
zx2 gears are not an upgrade
next autocross is this coming sunday (May 7th) at Timber Rattler Stadium in Appleton, WI, held by the Fox Valley Sports Car Club (FVSCC.com)
Next one after is May 14th at Rockford Speedway, held by a Midwest Council club, Madison Sports Car Club
I actually sent in a broken tranny and got a rebuilt one (dyno tested) from mantrans.com, for 850 to my door. Before that tranny ever touched my car, I put the LSD in it, and it's in and working smoothly right now. The only thing I did with the gears was put a 626 5th gear in it.
Pictures are now up of the Parts, Disassembly, Reassembly, and the modifications to the intermediate shaft bearing carrier.
Go Here to see them
I will eventually be putting together a howto with some tips/tricks type things, too.
Lookin good sarge, what's your next project gonna be?
well, I'm going to get the 3" exhaust on my '85 Volvo 744tic, along with the Browntop injectors, and the front poly bushings, and a brake job, that way I have transportation back and forth to work and farther while I get ready to use all the other parts I've collected on the escort.... :twisted:
Bumping to the top again.
This should be a sticky
Here's some more fun stuff that happened:
In an autocross, I broke an axle. It was the passenger side one, exactly what I was hoping for if anything were to break. Takes less than 15 minutes to change, if you've got all the tools with you.
so far, the car's handling is MUCH better, and the power that it can get to the ground is helping autoX's and track days a LOT!!!!
I just changed tranny fluid last week, and I think i didn't have my tranny gear in quite right, because it broke off, and is blocking the control rod inside the tranny, so I can't get it into 1,3,5 right now. Not a big deal, really. I need to pull the engine anyway to do a front main seal, and doublecheck the rod bearings and all that stuff. I think I'm going to put in, at a minimum, an area on the top of the tranny to fill from, so I don't have to deal with teh speedo gear so often.
I finally put solid mounts in the wagon also, so now i can launch well, without getting any wheelhop making me worry about the diff. Everything seems to be working very well, the LSD is teh r0x0r!
Well... i'm officially jealous.
Can the mod for this section sticky this once and for all?
What he said!!!!!!
good news for sarge and anyone else attempting this:
it has been discovered that you no longer need custom axles. you can actually use the stock axles and stubshaft from a 94-97 kia sephia with the 1.8 dohc motor, and a manual trans. it is actually a bp.. and the trans itself is slightly stronger. the MSP diff also drops into it with even less grinding than our stock trans. but anyway, the kia axles work with our trans + the msp diff. hooray!
dont forget that 98+ sephias are COMPLETELY DIFFERENT. they also offered a 1.8dohc but it is NOT a bp, and nothing interchanges
Bump back up since i just bought an "extra" EGT trans today for some work over the winter
guys you can get them here:

there are 2 versions. The original is better at going around turns, however is weaker. I broke mine after 40K . Most just take them out, reweld the diff and then put back in. MazdaSpeeds replacement for the defect is a whole new torsen unit. I now have the torsen in my speed and I cannot notice and difference from the 1st aside from I have put 100k on it with double the engine output at times and its held together fine lol
best $579 you will ever spend, grab gtx gears while you have it apart.
the problem i see is that the GTX gear ratios are different. but hey it might work. plus they arent any stronger as far as i know, thats the GTR trans.
How much different? 8)
significantly. i have the gear ratios at home (i have the mazda factory service manuals). the final drive ratio is also different. so i dont see how it would work right with the MSP diff, unless you keep the stock intermediate shaft and put the GTX gears on it?
