Yes, the bell housings ARE very different btwn the the 1.8 v-6 and the 1.8 BP engines. I have no idea where you pulled that code from.....Not correct.

The code for all of the G series PROTEGE 1.8 DOHC gearbox's were:
G5M-R from the 90-92 model yrs.
G25M-R from the 93-94 model yrs.
And that's not missinformation.

Curtklze, I'm using the G25M-R from a 93 Protege for my swapped BP-T.

Thank you :D
As far as I can tell, it is the same transmission as the G15M-R that is in the BP powered Escorts, Proteges, as well as some Festivas, 323's, 4cyl Probes, 626's & MX-6's, BP powered Protege's, except for the integral bell housing which is adapted to fit the 4cyl block.

If you can prove a G15m-R existed in any Probe, Festiva, 323, BP Protege, Mx-6, or 626, other than a single post by David Colman, I won't stand by it. Most of these car's with a 4cyl used the F series gearboxes. Like David wrote, the 6cyl's used the G25M-R gearbox's.

You may want to re-research your info on the types of trannies Mazda used.

And No...

While I agree that most bellhousings are easily removed, have you tried swapping Mazda bellhousings lately? Didn't think so. I just replaced my transmission (F series). The actual "bellhousing" isn't just the clutch cover, if you seperate from the transaxle casing you expose the guts, you will need to ensure that the rest of the case is identical in every way. Trust me on this, I have my old transmission in pieces sitting next to me right now. The G-series transmission that you guys are looking for was later replaced by the F-series for all fwd 4 cylinder cars in Mazda's lineup. There is no G-series transmission found in any of the newer cars. You could just get yourself a transmission from the new MS Protege and bolt that up with the lsd if you like or any protege for that matter and order the MS LSD from you dealer as it bolts right in. A big difference between the old transmission and the new version is the old ones had taper bearings on the LSD where as the new ones don't so they offer a slight advantage. Either way, the stock lsd sucks, I sheared the guts right out of mine with my B6e...not even the B6T. :shrug:

But as said, the G15M-R tranny is similar to the F25m-r tranny, maybe it is a G tranny for all vehicule, and called F for lower resistance.. I really don't know..

I know someone who got a used 2.2l tranny lying around, cause is Probe is broke, I'll try to read the code on it..

If I found the code, I'll write back, otherwise, I'll stick that there is a G25m-r in the BP cars..

This is 100% fact. I have the Protege manaul and this information is correct. The 1990-1992 1.6L SOHC and 1.8L SOHC motor come with the F5M-R transmission. The 1993-1994 SOHC motor came with F25M-R transmission.

To return to the heat of the subject..

I have swap a tranny from a K8 to a KF, and took picture..

Now, I'll swap engine for my B6 soon.

I'll analyse both bolts paterns, and get more informations!

Honestly, is there someone that saw both, and compare yet? Seems peeps with V6 only do V6, and peeps with 4 only do 4..

Oh, and I do have now a spare K8 .. ;)

Don't worry about the tranny guys i've been running my gtx engine on my g25 tranny all summer and it survived (did about 100run on 1/4 this summer) and i have a friend that has his on the f serie tranny and it survived has well.

P.S. don't worry about the tranny breaking at 300hp it's not has easy has it seems to get there.

Not to just bring up old threads btw.

I should state that I'm wondering about the FWD 323 GT B6T cars

I've been running the (I thought it was a G-25??) 92 Pro-LX DOHC tranny bolted to the B6T and it has held up well...to the VJ-14 setup I was running. The car smoked the tires at ANY speed in first or second gear just by bliping the throttle....no clutch, just hit the gas from a roll. Between Shay and I we've broken 4 or 5 of the SOHC trannies. The F series from the SOHC is WEAK. Right now I'm researching ways to strengthen the Pro-LX tranny to hold about 600 lb/ft. of torque. By using the Mazdaspeed LSD in place of the stock Diff, the Pro LX tranny can hold upto around 380 lb/ft. of torque before it hits a different weak point.

As far as which to go with......

-The Pro-LX has a much taller 1st and 2nd gear.....very nice for a turbo engine.
-3rd gear is close to the F-25, 4th is shorter, 5th is a LOT shorter (swapable with taller MX-6's 5th gear)
-Pro-LX tranny is a LOT stronger
-LSD's readily available (some mods needed to run the Mazdaspeed LSD)
-The biggest down side is moding the jack shaft bracket when using it on the B6 series blocks, they are shorter than the BP's (It's easy for me now, did the last one in about 30min.)
-I'll be using it in my drag car and offer strengthening solutions for those who need it. I won't be offering them until after I have enough testing to show the fixes work, not till later this year.

PS

According to Corksport (Derrick Ambrose) the 323 trannies are not much beter than the F-25 (MX-3 SOHC). That was one of the first trans. questions I ever asked years ago! You would think it should be stonger..but it isn't much.
