    I stole this from http://www.projectmazda.com 8) Gro Harlem wrote it up back in the ol ERDT days. Once of those missing pieces when it crashed.



    This guide covers the various suspension parts that interchange between the following models:

    * 1991-present Ford Escort
    * 1997-present Ford ZX2
    * 1991-present Mercury Tracer
    * 1990-1994 Mazda Protege
    * 1990-1994 Mazda 323
    * 1992-1995 Mazda MX3

    First of all....the 1990-1994 Protege and 323 are basically the same car, using the same chassis and unibody. The 1991-1996 Escorts and the 1997-present escorts and ZX2's use the SAME chassis as the Protege/323 (known as the BG chassis). Thus most every suspension part will interchange with a few minor exceptions. The Mazda MX-3 uses the same unibody as the Protege/323/ZX2/Escort/Tracer hence why so many suspension parts interchange. The MX-3, however uses a different chassis known as the "EC" chassis. The main differences between this chassis and the BG chassis is the different swaybar design that uses droplinks instead of endlinks. The control arms and trailing arms are of a different design and the rear disc brakes on GS models use different style calipers.

    Strut Tower Bars-
    It is easiest to find MX3 strut tower bars on ebay or online. All MX3 strut tower bars fit the 90-94 Protege, 2nd gen escort, 323, and the 3rd gen Escort and ZX2. The 3rd gens may require some re-location of various brackets as there are more systems (like ABS) and stuff. The rear bar does fit, but require trimming of your trunk interior to fit in the 97+ Escort sedan or ZX2 hatchback.

    Tie Bars-
    Not all tie bars fit all cars. An MX3 rear tie bar will not fit on a 3rd Gen as the mounting points are different. For rear tie bars, MX3 tie bars are easier to find than escort or protege tie bars. Front Tie bars from the Protege, will fit the 2nd gen escort. I don't know of anyone who fitted one to a 3rd gen Escort/ZX2, but it probably fits. I have a MX3 rear tie bar on my car, and it fit great.

    Swaybars-
    All front swaybars interchange between the Protege/323/Escort/ZX2, as does the rear bars. The MX3's bars WILL NOT fit any of these models. This is because they utilize horizontally mounted droplinks rather than the vertically mounted endlinks found on BG chassis cars.

    Bushings-
    Control arm, Trailing arm, Steering rack and swaybar endlink kits will interchange between the Protege/323/Escort/ZX2, and possibly the MX-3 (no one has tested them). Shift stabilizer bushings are the same between all Protege's, 323's, MX3's and 2nd gen Escorts and Tracers (1991-1996). The 97+ Escort and ZX2 use larger in diameter bushings which will not fit.

    Motor Mounts-
    The engine mounts for the Protege, 323, 1991-1996 Escort & Tracer, and 4 cylinder MX-3 RS are the same. The 97+ Escort and ZX2 may use the same mounts, but no one has yet to test this. The #1 and #2 lower transmission mounts for the ZX2 will interchange as the Protege/323/2nd gen Escort&Tracer and MX-3 RS however. (this has been tested). Since the MX-3 GS uses a V6, none of the enigne mounts are the same and will not interchange with the exception of the #4 mount located under the battery tray (upper transmission mount).

    Struts-
    All MX3, Protege, 323, ZX2, and Escort struts will fit one another, but the ZX2 SR (and maybe all 3rd gens) use a larger diameter strut shaft. so you will need to use ZX2 thrust bearings (also known as strut bearings) if you want to use the ZX2 SR Tokicos. These are easiy modified into the MX3, Protege, 323 or 2nd gen Escorts upper hat. Please note that the ZX2 SR struts are .5" shorter in legnth.

    Springs & Coilovers-
    All spring will interchange but each spring is designed with the cars weight in mind, so if you put MX3 springs on your Escort, the spring rates aren't going to be correct, so keep that in mind.

    Coilovers seem to fit, but Let it be known that most won't fit the ZX2 SR Tokico struts without having to shave down the shaft (which is too fat to slip the sleeve over). All otehr struts will accept the coilovers fine.

    Strut Mounts-
    All strut mounts are identical for all of the forementioned cars (Protege, 323, Tracer, Escort, ZX2 and MX3).

    Wheels-
    All of the forementioned cars use the same 4x100mm bolt pattern and use similar offsets. All of their wheels will interchange. All of these models tire and rims sizes are listed below:

    1990-1991 Mazda Protege 4WD: 185/65R14
    1990-1994 Mazda Protege SE/DX: 175/70R13
    1990-1994 Mazda Protege LX: 185/60R14
    1992-1995 Mazda MX-3 RS: 185/65R14
    1992-1994 Mazda MX-3 GS: 205/55R15
    1991-1993 Ford Escort Pony, LX and Wagon: P175/70r13
    1994-1996 Ford Escort Base, LX and Wagon: P175/65r14
    1991-1993 Mercury Tracer Base and Wagon: P175/70r13
    1994-1996 Mercury Tracer Base and Wagon: P175/65r14
    1991-1996 Tracer LTS: P185/60r14
    1991-1996 Escort GT: P185/60r15
    1991-1993 Ford Escort LX-E: P185/60r15
    1997-2003 Ford Escort & some ZX2's: 185/65R14
    1997-2004 Ford ZX2 w/wheel option: 185/60R15
    1997-1999 Ford ZX2 SR: 205/55ZR15 with a unique wheel style

    Hubs, Rotors and Calipers-

    There are two different diameters of drive-axles used in the BG and EC chassis cars. There is the F-series transmission and G-series transmission found in these vehicles. All of these cars have identical wheel bearings, hubs and brake calipers and rotors/drums, and use the same brakepads and shoes. I will break down the cars in terms of which use F-series transmission and which use G-series transmissions: *Please note this does not mean these transmissions are interchangeable with these cars. It means that you can interchange internals from one to another.*

    F-Series transmissions:

    1990-1994 Mazda Protege DX and Mazda 323
    1991-1996 Ford Escort Pony, LX 3 and 5 door hatchbacks and 4-door sedans and Mercury Tracer (base)
    1992-1995 Mazda MX-3 RS


    G-Series Transmissions:

    1990-1994 Mazda Protege LX
    1991-1996 Ford Escort GT, LX-E and Mercury Tracer LTS and Ford Escort Wagon
    1992-1994 Mazda MX-3 GS
    1997-2003 Ford Escort and Mercury Tracer with 2.0 SPI engine
    1997-2004 Ford ZX2

    If you put a "written by" line with your link to give the author credit, we'll get it stickied for you.

    I guess that would be the politically correct way of doing it... but it's still valuable information worth having readily available.

    No clue who wrote it. Run a "test sticky" for a month or so.. if nobody claims it, then make it permanent. could be a nice way of doing it.

    No, I'm fairly sure Donnie will not condone having copied information from a copyrighted source without at least owner knowledge with consent of the information being used. At the very most it should just be linked since that appears to be written by just one person using various bits of information found through various sources.

    Good call, James.

    citing sources has nothing to do with political correctness.

    I think a sticky with the link would suffice. Cting sources and getting permission is the right thing to do, and I agree it should be done here if it is going to be reprinted, but I dont think there would be anything wrong with just stickying a link.

    If you guys are still looking for the guy that wrote that, it's Gro Harlem, I think his name is Wil, he used to be on ERDT, and still is on clubprotege.com. He posted it himself back in the day on ERDT , I doubt he'd have a problem with it being posted again, but you could send him a PM or an email I'm sure.

    Difference between the F and G trannies? slightly different gear ratios, different input shaft diameter (G's are a little bigger I believe) and spline count.

    you cannot take an F tranny from a protege and put it on a 1.9L escort tracer, though... although the internals are the same between the trannys, the bell housings are completely different because the 1.8L block is completely different from the 1.9L block.

    brake calipers

    So then do you know for a fact that a big brake kit from a mazda mx3 rs will fit the 96 3dr hatchback without a problem......or at least the bolt pattern is the same for the caliper?

    I wish you guys dipped into the first gen interchangeability. I think tempos had similar setups to the first gens.

    Found an error.

    No Ford powered cars came with the G series transmission before 1997.
    All 91-96 wagons had the 1.9 ford powerplant and corresponding F series trans.

    Resurrecting an old thread here, but what is the difference (if any) between the rear struts on a 91-96 GT and regular models? I need a strut for my 95 GT but none of the junkyards have anything for a GT but one guy doesn't think there's a difference. Figured I'd check with y'all before attempting it myself.

    the sedans and hatchbacks are all the same, definately. the wagons may be slightly different due to the extra weight in the back, but not significantly. i know you can use the zx2 s/r struts on a wagon with no problems so they are close enough.

    why are you going with junkyard struts? i'd recommend new ones if you can afford it. you can get a set of 4 s/r struts for about $150, then you just need zx2 strut bearings for the front and a dremel tool to enlarge the mounting hole on the front top strut mounts a little bit, to fit the larger bearings/strut shafts. rears bolt right in.

    no matter what you do, remember you must replace struts in pairs (front pair, rear pair) or you could really mess up your handling.
