thank you thats what i was needing to know

BTW--

VII. Transmission Information:

To clear up any confusions, you must understand that all of the cars listed above have transmissions that will directly bolt onto ANY of the engines in this FAQ. YES YOUR TRANSMISSION WILL BOLT UP!!! Now that you know that, you might be wondering about possibly swapping your transmission for a stronger G-series transmission. If you have a 323, MX-3 or Protege DX, you have a Mazda F-series gearbox. This transmission should hold up well to any of these engines. It has taller gear ratios which are geared for fuel economy over performance and smaller, 22mm diameter axles. It has been known to hold up to about 200 horsepower and ft-lbs of torque without reliabilty issues when not abused.

The Protege LX, Escort GT & LX-E and Tracer LTS all have G-series transmissions. These transmissions are used in numerous Mazdas including all 2.0 4-cylinder & 2.5 V6 MX-3, MX-6, 626, Ford Probe and 01+ Protege's. They have been known to hold up to over 300hp and ft-lbs of torque when not abused. They use 24mm axles and utilize an intermediate shaft to reduce torque steer when accelerating off the line. All G-series transmission have either a 4.11 or 4.39 final drive ratio and short gear ratios for quicker acceleration at the expense of fuel economy.

To swap a F-series for a G-series, you will need to get the axles, intermediate shaft from a 90-94 Protege LX, 92-94 MX-3 GS or 91-96 Ford Escort GT/LX-E or Tracer LTS. The hubs & brakes do not need to be swapped out on any of these vehicles. Swapping the other parts out will allow you to use one of these transmissions. Be sure to get the transmission mount brackets & mounts when you buy your transmission as they will be needed to mount it.

can anyone confirm the part I have in bold?? Is he basically saying that a transmission from a V6 engine can be swapped onto the BP engine?? last time I was in the junkyard I had a look to see if I could get a transmission from a 2.5 V6 MX-6 and it was totally different, there was no way it would bolt up, the starter motor was on the wrong side and it was a different shape.

the V6 tranny is internally the same BUT the bellhousing is different so no it wont work

[93-mx-3]

ok so wen i do my swap (93 mx-3 w/sohc to the 90-94 bp) i should b able to just bolt, plu, connect, n play..simple as that? all wires match up, all bolts line up, transmissions line up n everything????? it seems too good to b true......

[papa roached]

the only wires you are missing are the ones for the VICS and those are easy to add as i understand it but yes, everything plugs in and goes

[93-mx-3]

the ones on the vics????wats that?

[93sohc5speed]

the ones on the vics????wats that?

this will tell you

[93-mx-3]

so its like hondas vtec or toyotas vvti?

[sauga]

I have been reading this thread and it is very informative but just when I think everything is going to swap without any problems, someone mentions that they are talking about a sohc etc. Can someone that knows for sure please reply to this post and confirm that it the same wiring and mounts etc. Also if anyone knows where to get a strong bp-ze complete drivetrain I would appreciate the info.

Thanks alot

[mazdax3speed]

it is [u]NOT[/u] the same mounts for a 94+ DOHC MX3 you WILL need the rear tranny mount, and i think, i can not remember, the drivers side mount, both can come from whatever car u get the tranny from, excort protege SOHC mx3

but the rear mount will not work, and either the drivers side mount or the front tranny mount will not work too

also remember if you get a new tranny you will need new axles, i dunno about SOHC trannys maybe they are differnent, but with my DOHC axles did not fit the escort tranny, and remember one is a halfshaft, and you need that entire peice

[duncanisdumb]

ok, so i have a 1992 mx3 1.6l sohc. I can put the BPT motor into it no problem then?? The motor comes with a awd tranny, and i can boly my stock tranny onto the motor right?

[mazdax3speed]

yes, AWD tranny is of no use unless you have a 323...im tryin to sell mine to an owner of the 323 right now
its sugested that you buy a Gseries transmission (protege, escort gt, ect) but the SOHC transmission does bolt up

[nobodyhere671]

is it possible to plug up the awd transmission so it will function as a fwd?

[lowflyinmx3]

i have a 94 mx. if i get a 95 -99 bp i can keep my original guage cluster and speed sensor rite? i don't have to convert it over to the 93 and earlier cluster and analog speed sensor do I?

[facko]

nah you wont have to change clusters if u get a new gen bp

[steckino]

honestly I copied off all the useful information and printed it off... it came to 9 pages worth of stuff. It's very insightful, and deffinetly will help me tomorrow, as I will be going to a salvage yard where there is a I believe a 94 or 96 protege(forgot what year) The motor actually looked nice, rather clean for a salvage yard motor. I'll be taking my dig. camera and taking some pics and I will post it all up. As for all this information. If someone wants the actual file so they can print it off, feel free to message me. I'm usually home.
