Post specialtyneed '94 MX3 RS
Got a '94 MX3 RS B6-DE man trans silver with 179k mi dead with bad disty for $700 in St Louis drove 800 miles to get it $150 is gas and $62 in salvage disty parts for mod posted in this forum . The primary ohm'd out over a ohm (factory spec is narrow) too much and the secondary was open, $57 coil fix minimum with about 70k mi life so not good to leave it oem. Has really good paint some body damage though on front bumper minor and larger area deeper pass side behind door affecting closing and damaging seal.

Just removed:
2 good amps, a Kenwood EQ and a very good reputable Kenwood CD changer to trade maybe (post link later to items for sale) for a good head unit and suitable speakers direct mount in the MX3 and may be parts (set of alum rims?) I want or need:

KDC-C661 CD auto changer known for reliability and rock stable. DIN control cable inc. Click on image for full size.Image


A300.2 Precision power Art series 200 watt bridgeable amp (attractive white with colored graphics) has soft on features. Click on image for full size.Image


XS 2500 Phoenix Gold 500w @ 4 ohm/700w @ 20 ohm competition amp very heavy with 14 large heat sinks & gold contacts. Is underrated at 12v in compete in lower class, feed it 14.4v with a underdrive pulley on a good high output alternator use 4 ga power cable instead of 8 ga and she doubles output and is bridgeable and loaded with features.Image
Image


EQ info to follow (still installed).

Write up with schematic on how to do this disty swap is here with credit to 4gotn and lazzer08 I just added here the correct CAS wire colors and a optional near oem coil placement description. Pics to follow later this week after I fix starter solenoid problem below:
http://www.mx-3.com/phpBB3/viewtopic.php?f=24&t=69706

On friday got all the parts needed for disty swap out from (Maxda?) all internal oem type to (Ford?) external type mod. Out of about 1200 cars there were several Maxda's in the salvage without the disty's and only 2 left with the internal type. Pretty obvious these are a problem. Got disty, RIC (radio interference capacitor), 3 wire module, coil and bracket, all the plugs and the entire harness that connects them. Took time to strip all else unrelated out hoping I can rout the wires in the factory harness and eliminate making some splices due to our goal of making it look oem. It all was off a Escort wagon with the DOHC 1.6L I think (don't think the year was on the fender where it normally is marked). only exception was the cap one on the escort was cracked at the mount screw common prob si I robbed a mazda SOHC since they have the same cap. May get a new rotor since the one off escort has a loose rivet. Will get the vin and year tomorrow if I go back for a few small things and maybe three alum rims I saw in a black 94 mx3.

Saturday we mounted the escort disty, spent a lot of time working out coil placement because I wanted oem placement and resistance to crash damage and water, salt, vibration and heat damage.

Had another problem making room tight with the HID ballast wiring and the control box being mounted to the tall tab absent on the escort coil/ fuse/ RIC mount bracket and in the only space available between battery and air filter box that would allow use of factory length of harness from RIC, module, and the coil plug.

So we used the mx3 bracket for main fuse box and defroster/ anti lock brakes fuses put the RIC under the aft fuses mount on inboard stud. Then reversed the "L" bracket to go under coil and drilled the small "L" bracket near center and forward a bit (nearly centered at a small indent in the coil) and bent the "L" just a bit forward to clear the shock tower with the coil bulge. Coil tower is now facing the fender. Snaking in and turning the self locking flange nut on the inboard stud was the only thing hard besides getting the hole placement near prefect. This made a three item stack up on that stud with RIC, Fuse holder mount and reversed coil "L" bracket. Made a solid mount and almost in the oem escort location up high out of harms way which is mounted on the escort in place of the 2 fuse defroster/ anti lock assy. This allowed wire routing in a square around the fuse boxes perfectly only the coil wire interferes with the fuse box lid access and can be rotated or pulled out easily because I use plenty of dielectric. We left the oem spiral wrap and heat shield coated with dielectric wrapped the coil wire with more heat shield and routed in between the battery and air box along with the two RIC wires. The rest are longer and will go in or attach to on top of the large factory harness, will edit post if we change it. I will post pics of the coil detail and orientation and finished project.

Sunday night we drained the 8 month old fuel (nice drain plug most vehicles no not have). Drained the oil, was too dirty for my liking. Then removed valve cover cleaned the minimal amount of build up. The Mobil 1 kept her satisfactorily clean. Sprayed the cam lobes and lifters with prolong and doused the upper end with HD 30 oil and then filled the crankcase with HD 30 for a temporary engine clean out.

Got her running she started no prob with the following 2 exceptions:
1. Had to swap the CAS (crank angle sensor) wires like the notes state. The correct connection for mine (should all be same) is from the:

Original 6 wire plug CAS green to the white on the new 4 wire dist connector and
Origional 6 wire plug CAS violet/white (violet wire was very faded and looked nearly white) to yellow/dark blue on the new 4 wire connector.

2. Only real problem now is the starter solenoid began dropping out after less than 1/4 turn of the engine after the first 45 seconds of turning over uninterrupted operation. Longest start attempt was about 20 seconds when she would not start before CAS wire swap. Removal and testing found solenoid failed the first test terminal M to S it should have had some continuity but passed the 2nd S to case (coil windings has some resistance) and works fine under no load. Today robbed a newer kia for the solenoid and its now intermittent on dropping out. Will have to check "S" wire voltage from ign switch.

During troubleshooting before the CAS wire swap we could not hear the fuel pump is it a solenoid type and real quiet I have not seen one of those since my '80 Prelude? Nearly every other vehicle I own (9) we can hear the rotary pump in the tank wining for 3-4 sec with key on.

2 unrelated musings:
Timing belt interval manual states is 60k mi is this real life service limit? My answer manual and today acquired drivers manual state 90k mi and 104k mi respectively. Seems CA wants it checked at 60,90 and changed before 104 and rest of states they want 60. Ambiguous. The half moon design lasts on most cars that ere past 104k mi and only on my metro 1.0 L 3 cyl (engineered earlier than this engine) does it snap at 73k mi like a fine watch.
More importantly, factory service manual (FSM) states damage "may" occur if this 60k mi limit is exceeded implying the engine is interference valve timing, it it? I thought I saw a post that said it was not. Need to read more n the FSM.

Changed the oil filter to a cheap one will change out after about 300 miles with the hd 30 oil and put in Mobil 1 syn 0-30 effeciency oil which meets both the 5w-30 and 10w-30 specs. Jumped the 10 to gnd @ the diag connector & set the timing the early AM Tuesday and got her real warm. Idle settled down nice and smooth about 700 per spec. Ran the trans through the gears and let the wheels spin up on jacks slow in 1st and reverse. All okay so far. Will have my 19 yrs old check drain plug for wear particles, type, oil color, smell & speedo gear for trans oil level tomorrow. Removed air box, batt and air tube mas/maf assy so I can tidy the disty wires & wrap up tomorrow. Got syn blend 80-90 for the trans and need to locate a fuel filter (old one is rusted badly) and bosch x2 plugs at Pep Boys later today.

Post Re: specialtyneed '94 MX3 RS
All in one disty to external mod complete. Works perfect. Installed a new batt hold down. Shorted diag TEN to GND & timed her carefully and indexed it for future use guessing which mark to use since they both looked white in the early morning hours (I am pretty sure one is yellow, will repaint later) and the sound smoothness and rpm was right with the lighter one. She has good power smooth, trans was smooth & quiet. However when I drove her her the first time to gas station about a block away with a lot of racket from DR front suspension tire was angled out in front and pulling bad to left. Had my 19 yr old check it. Strut spring was broke. After I get spring(s) we will do our own alignment (have done several now ourselves) and maybe be insured and daily driving by this weekend. Here are pics:
Let me know if they do not work right.

Coil installation pic:
Trying ImageShack.us for this image imagehosting.com is getting hijacked on firefox 4.x I am using tonight so may switch all of the pics to ImageShack.us.
Thumbnail click for full size.Image

Ironed out the starting issue for now by playing with the clutch since the interlock switch is in series with the ign start switch. Will try to get circuit ohmed out and replace the offender this week.

Thanks Robert (4gotn) again for the help on the disty and your experience with the starting issue.

Fixing the broke center console lower hinge tonight.

Need to get HID headlight bulbs soon also.

Got the following supplies to change items soon:
Trans oil &
Brake system flush.
Fuel filter.
XG oil filter.

Need to research spark plugs. I like the NKG .07 fine wire iridiums that nascar used not long ago but I can not find them anymore or at least not for this engine. Also need to do the electrode clocking thing with them.

Got a used similar mileage range 131k front strut spring yesterday, last one they had at the salvage for under $12.
Putting it in today then trouble shooting the clutch interlock switch for the intermittent starting problem.

Next the HID bulbs or or ballast troubleshooting then,
Insurance and tags and taxes.

Then rework of headlights and front signal lenses damage and front bumper touch up.

Post Re: specialtyneed '94 MX3 RS
We got the used vgc Dr front strut spring in today knocked off small rust areas that ferreted in the coating on it some rust conversion primer for insurance and epoxy black top coat to match to prevent early failure. She drives very good no awful racket any more. I detected a very slight noise though in the rt dr front will take more than 1/8 mil road test I dared to take in the dark to isolate it.

The only thing I do not like about her so far is the shifter seems to be a wide throw and very loose pattern. Maybe I can trade some of the high powered stereo amps and CD changer equipment I took out of her for a good short throw shifter and a modest head unit that is more to my liking. Only one thing to get night legal:

Just needs some working 4200k +- 100k or so HID 9004 or 9007 bulbs for the kit previous owner put on. Old ones are inop, burnt up I think.

We discovered a option added today when opening up to knock out the big dent in the pass side behind the door. After market electric lock added to that side. I had not seen the switches for those. Curious need to ferret out where it/ they are.

I believe the car already could have had power locks controlled by the position of the drivers side lock switch. (above the door handle)? Mine has this...

Ps you needs some pictures!

Post Re: specialtyneed '94 MX3 RS
Possibly I am incorrect. Maybe your right. I assumed its after market due to the new look of the boot and the universal type stamped steel multi hole mounting strips. and the lack of twist on the wiring near the servo except near the front of the door they did twist the wire a lot (tight) near the speaker. I have pics just need a good free hosting site (no spam) saw it in a post just can not find it tonight.Image


Tonight saw the 323 manual steering mod and like it. I have been used to manual steering for about a total of 260k between the Prelude and the Metro now. Will be doing this asap junk yard style. Given I can find a good rack with a tight (good) bushing. My MX-3 has pretty new good tie rod ends already and I do my own alignments making this mod a win every way around likely paying for itself in MPG improvement in less than two months. Do not know if the aspire thing has been done yet but if the ratio is better like the stock 3:1 to stops then I am interested. Either way its great way to get rid of a lot of problems, weight make more room and save fuel money.

I think only the GS has power following passenger door locks from the factory.

Photobucket now has unlimited photo storage.

Tonight my 19 yr old started replacing the Dr seat cusion in the MX-3. He also primer sealed and started base coat on a 97 Escort 2000 SPI and installed a reman pass axle in the '94 Villager. He has been doing a good job lately have to brag a bit in him.

Added several pics tonight in thumbnail size. Check out the CD changer and amps in the first post. Also better pic of coil placement for disty mod added. Click on them for full size. I like ImageShack.us better except they are not easy to upload several images at once. May try the bulk uploader later. The toolbar plug in with drop and drag I tried to install for Firefox 3 (I have 4.x) did not work.
ImageImageImageImageImage


Pic of the pass rt area behind door fender bender damage from parking lot drive off during previous ownership. Photo is turned 90 degrees to take advantage of camera and narrow area between vehicles.

It has been suggested I inflate a basketball or soccer ball to push this out and avoid some metal stretching. Not such a bad idea. Any one ever tried that in this area?

Here are two night pics of the car the rear view is best in full size(click) daylight pics to come.

Okay hard question.
How do I get one of these thumbnail pics re-sized to 75 pixels without making it too distorted to fit in my signature without using a big pic editing program on this ancient dell computer with hardly any ram?
