My Mazdaspeed Conversion Build

btw, your speedometer won't work no matter what you do unless you have ABS.... if you don't then the only way to fix that is to crack the tranny open and install a speedo gear...

With regard to the speedometer/odometer, the 2003 and 2003.5 mazdaspeed protege comes from the factory with an RABS system. The RABS electric analog speedometer receives the signal from the ABS sensor located on the inner most steering knuckle of both the driver and passenger side spindles. It lightly touches the axle gearing just in front of the axle splines which insert into the hub assembly. With it's light contact, the sensor reads revolutions/sec (speedometer and odometer), and other useful information for the ABS system.

The 1999 ES comes from the factory with a TISOM (transmission internal speedometer and odometer module). With no ABS system to speak of and no TISOM in the msp tranny, the RABS system cannot be carried over to the 99. More than likely what will end up happening is I will end up using a PSOM (programmable speedometer and odometer module). The PSOM system uses a microprocessor that receives revolutions/second data from the DSS (differential speed sensor). The microprocessor crunches some numbers to convert the the electrical signal to the 8000 pulse/mile output which is what can be read on your tach's speedometer. A similar PSOM is used in ADL dashes (automatic data logger).

I could have gone into this much detail for every single issue that I listed in my original post but I figured I'd spare everyone-- the writeup is long enough as it is.
 
all the proteges that have ABS are 4 wheel ABS systems... I don't know where this "RABS" thing comes from

there's no "module" in the non-ABS transmission... it's simply a worm gear driven electromagnetic sensor (a mini generator that creates AC voltage that the ECU will receive)... all the signal processing is done by the ECU and gauge cluster... the speedo sensor/gear is installed on the differential itself on a non-ABS tranny/car

there is NO "differential speed sensor" on the protege

ABS can be retrofitted onto a non-ABS car.... you just have to swap every piece of hardware and wiring over... is it worth it? NO
 
you install the differential speed sensor, I said what will more than likely end up happening is I will use a DSS. I didn't say use the DSS

The side motormounts were not matching up to the frame. It was either drill into the frame or fabricate a new mount. I decided to fabricate a mount to keep it cleaner. The splines on the driver side msp axle were not fitting properly into the hub assembly of the 99 spindle-- perhaps the splines were damaged somehow. So, a new axle was fabricated and splined-- not a huge deal since the machine shop is right next door.

I have no brackets for the radiator or the side mount-- therefore they had to be fabricated as well.

I'm aware of the speedometer situation-- I've been aware of all of this including the wiring discrepancies since day1, it's actually the main reason why I was hesitant to do the swap in the first place.

like I said, I don't see how it won't "match up" when negatize did his swap it all bolted right in... like I said, he has a 99... the only thing I can think of is you're missing pieces for the swap... all the mounting holes for all sorts of s*** should be there on even the 99s... mazda has already been selling the sport20 in 99 in japan, which is the wagon version with the 2.0 engine... and yes, the chassis is the same
 
I guess I shouldn't have smoked that PCP before putting in the motor mounts(ugh)

and keep in mind I wasn't fortunate enough to have a donor car. All I had was what I ordered.

ok... but let's not complicate matters by using all these fancy terminologies... it's a simple speedo gear/sensor and that's it (in fact the correct terminology is "VSS" which is vehicle speed sensor)... that's the way it's been for all the normal proteges.... the ABS cars is not something we should care about since it uses the wheel speed sensors (which is called the "WSS") for the ABS functions and mazda saved a few bucks by stealing the signal off of it for the speedometer, nothing special about it or unique specifically for the speedometer on an ABS car... and just so you know, the pick up sensors don't EVER touch the toothed rings on the axles/hubs.. they are always slightly away from them... if they touched then s*** breaks!
 
you are trying to argue over milimeters here with me edwin. I'm not looking for arguements, so don't look for them in my thread. If you think my build will fail, then laugh it up when it does all right?

It's one thing to sit back and naysay, but it's a whole other thing to actually be doing it. Instead of putting in your two cents about what you think I haven't thought about and talking about how my build will fail, how about simply asking if I have considered these things or asking what I plan to do to get around them? Instead of attempting to trash my build, how about you try to support it? This is supposed to be a community where we all support one another. If you're going to critisize, please do it constructively.

Back on the topic of the build:

Tomorrow my plans are to

1.) Fabricate brackets for the msp radiator and SMIC
2.) Remove '99 radiator and install msp radiator
3.) Replace radiator hoses
4.) Radiator flush, new coolant
5.) Install SMIC, connect all piping
6.) Modify CAI to fit this application
7.) Put on slotted rotors and new calipers
8.) Remove '99 suspension components.

I'll take some pictures tomorrow at the end of the day to keep the thread updated.

I thought even the newer MP3 did NOT have ABS.
 
Thursday 8/24

Big day for the build today-- much was accomplished.

First thing on my list for today was to remove the 1999 radiator and radiator fans. After it was removed, the msp radiator, radiator fans, and SMIC were mocked up before the install. I found out then, that there was not enough space between the front of the SMIC and the existing AC condensor on the 1999. So, the lines were purged and disconnected and the condensor removed, in addition to plugging the lines and the receiver to prevent debris from entering the system. Side note, I need someone to tell me if the msp AC condensor is only as wide as the radiator itself or if it spans the entire distance between the headlights like the 1999. If it it shorter I'll have to order the MSP AC condensor. If it's wider I'll just have to modify the brackets to make it sit up further in the frame.

With the condensor out of the way, the msp radiator, radiator fans and SMIC were installed and bolted into place. There were, however, two problems: The first major problem was that the passenger side radiator fan's electrical receiver was not compatible with the 1999 passenger side sender. So, the receiver (wires and all) from the 1999 passenger side radiator fan was swapped with the msp passenger side radiator fan receiver with some soldering. After that was complete, the sender/receiver hooked right up. The second major problem was that I didn't have the msp radiator/smic brackets. The brackets from the 1999 were not compatible because the msp radiator and SMIC sit flush with the frame (they are about an inch taller) whereas the 1999 radiator sat about an inch below the frame. The 1999 brackets accomodated this by arching downwards to bolt up to the radiator. This obviously wasn't going to work for the msp setup, so new brackets had to be fabricated. Templates were drawn and after about a half hour with the band saw, the grinder, the drill press, the belt sander, and the dye-grinder... the brackets were finished. They sat perfectly flush with the frame and fit excellently.

After the radiator, fans, and SMIC were mounted and the sensors hooked up, the lower radiator hose had to be reconnected and the upper hose had to be trimmed and turned to reach the msp radiator (about 2-3 inches taken off).

Once things were functioning the intake situation was tackled. After playing around with the n/a injen cai piping to find the best routed design, I settled on a design that is pretty similar to the injen cai design for the msp-- it flows nearly the same and the filter still sits under the driver-side headlight. The couplers and MAF were connected along with the intake-to-head line and the ambient air sensor. There is however, no bung location for the stock bypass valve, so a 3/4 inch hole was drilled and threaded in the intake, and a 3/4 inch barb was screwed in to make the bung for the bypass valve. The intake was cleaned to remove all the metal shavings and reinstalled. The stock SMIC-to-throttlebody pipe was installed and the radiator filled with coolant. The engine was cranked and it fired up like a charm. The power steering resevoir was filled with PS fluid and the wheel was turned slowly back and forth to drive out the airation that had built up-- that's what was making that nasty whining noise in the video. The motor sounds incredible. The 95 durometer motor mounts make the frame vibrate when the car idles/crankes along with the rumble of the turbo-back. When I gave it throttle it sounded amazing-- much better than tuesday's vid when neither the turbo, SMIC or the intake were hooked up. With wide open throttle and the turbo cranking you can actually see the turbo-to-SMIC piping expanding at the ribs from the air displacement-- I absolutely love it.

Tomorrow will be another busy day trying to get the remainder of the wiring issues solved. I'll keep you all updated.

Also I found out something interesting the other day. My car weighed in at about 2570 with the motor swap, that's about 275 lbs less than the mazdaspeed protege curb weight of 2843 lbs-- I believe that's a correct figure.

I give you props for doing all this work but in the end it would have been cheaper to buy a used msp! The msp condensor is different from other proteges. The power streering cooler pipe is longer too. I suggest you pick up the MSP workshop addendum. It'll help you out in all the minute differences.
 
So far I haven't exceeded $3000, I think you'd be hardpressed to find a used msp for that. The clip also had 18,000 miles as opposed to my 99 which had over 100,000-- it's like getting another life for my car.

I enjoy working on/building cars and I love challenges. It will be nice to be unique among the 99-00's and be boosted for a change.

man with every mod (specially a engine swap) their are problems, u seem to have done your research and knew what you are getting into! great job on not just jumping headfirst into somthing u got an urge to do (like i do alot but i learn quick ;) lol) next time i am in NY i want to see this car (june of 07 probally so u have time)

would u mind fabricating me some radiator/smic brackets?...ill pay u...i have no clue where to find some for mine...

for the mp5 right? what's wrong with the stockers?

u know u can just buy msp brackets from the dealer for 12 bucks each and save the headache.
 
since i was able to pick up an msp radiator/smic for my turbo install, the p5 brackets dont fit the msp's setup...

edit: whats the part number for the brackets?...id like to avoid the dealership since the one closest to me isnt mazdaspeed and the next closest one always gets my orders wrong...
 
oh ok, yeah I can do that. If i get time tomorrow i'll just use the templates i drew up today. You might be able to get the msp brackets at the dealership quicker though
