Hmm, we had this issue brought up by Horci. It was for the Vin Registry.
I got you same error when viewing as a guest but I can see it when logged in.
The issue was broken link or missing file for the picture attachments. Let me know via PM if that changes anything. Picture is still live as of now. This weekend I can probably take some pic of Scrat with the 17's on board. They are so tall, they look good but the car was elevated even more than stock ride height which I think I duplicated with the coilovers and 15's in near stock rolling diameter 205/50's.

We are having issues with the internal file/picture hosting. The picture was hosted here as a file attachment.
I'll see about adding a pair of photos to an offsite spot to show last years set of wheels and tires and this years taller tire setup.

Great read for people considering differential choices on their FWD cars:

https://www.northamericanmotoring.com/f ... arned.html

All the same principles apply here, regardless of what car is using an identical part. Even better to see how electronic brake control is used and how it correlates to using an ATB diff or not!

I started a new thread for discussion on it, here:

Since 2005, this car has now traveled a little under 25,000 km's while under various stages of JSB'ing, rebuild/restoration and road-worthy statuses.

Update August 2017:

Clutch master wore out. Installed OEM rebuild kit but scoring in the bores leads me to believe I should be buying a new master outright.

Big box of parts from AE has arrived courtesy of the shipping department at PartSouq.com.
More parts scheduled to ship out when Amayama.com receives a few more parts they are waiting on.

I have a complete set of urethane front control arm bushings and rear panhard rod bushings to look at installation for this winter. The control arm bushings will go in a set of cleaned and grease free control arms that shipped in from California.

Received a vintage DSG shift knob that was a "thing" with the Galant VR4 guys. Now my C53A can be part of the E39A wannabe club. The knob is white Delrin and quote smooth. Should be cooler to the touch in the sun, but the AC still works well so that takes the extreme heat when I kick it in after running the engine for a while.

Using the wideband as a primary sensor and having simulated narrowband has a weird effect on the startup procedure I have to go through with LinkV3. Maybe it will hangs once I go back to dedicated narrowband signal and wideband secondary for logging and visual output.
Here is my scenario:

If I start the car, I have link set to a standard 15 seconds of "disregard the 02 sensor output", and it runs strictly off the maps. This gives me enough time to rev up the engine and get the car out of the garage before the wideband actually gives an output on the screen. If I drive away before the output comes up, my idle will be "learned" their on way, meaning it will be wonky. If I wait for the wideband to read (remember it has simulated narrowband output with Link), I have okay idle characteristics (which still could use tweaking). It is a bizarre phenomenon that I would like to solve. Ever stall in traffic an think about having to wait 30 seconds while idling to he a perfect idle at the next set of lights ... This is the point that gets me wanting to fix the whole setup.

I have been putting in lots of fuel, holding off on adding timing and playing with any setting this season. I just want to drive the car, the rest comes later. The bicycles were calling and life feels better when there isn't a car taking up space in your subconscious.

Catalytic is a CarSound Generic 2.5, and I hesitate to say high flow model. It is meant as a regular catalytic converter replacement, so not a racing model. We will see how it puffs for Etest in the spring.

Spring cleaning has me rethinking many things about the car.

First off I could never get my 02 sensor situation sorted. I will start with a fresh sensor, remove the wideband from the ECU input's entirely, and see what happens on a log.

I am going to order a new ntk narrowband sensor for main running signal to the ECU, and a new Bosch LSU4.2 wideband sensor for tuning input to the MTX-L.

Asked around and some are using the new MTX-L PLUS that comes with the newer, redesigned Bosch LSU4.9 sensor, but seems many are having issues with the sensor delicacy.
You can apparently updated the plug end and reflash the firmware in the MTX-L to use the newer LSU4.9 sensor, but I don't think I want to go to that hassle just yet.
Reasons why the LSU4.9 sensor is better, and a full comparison of the two generations of Bosch sensors and why they fail, 2 links:

http://www.nzefi.com/bosch-lsu-wide-ban ... lications/

https://www.ecotrons.com/accurate_lambd ... 2_sensors/

Next up are my thoughts on what I can do to return to better operation with regards to engine management and hardware/drivetrain changes to better suit my mood and the way the car actually gets driven.

The engine has always run a little funny, and it seems that tuners agree and the solution may be simple.

Run a narrow band sensor straight to the stock 02 input and use the wideband strictly as a comparison.

I was running narrow band sim, my signal for narrow band would no longer work with two different 02 sensors and even with rewiring a known good signal harness into place, no change.

Engine response and graphed output were showing a long or delayed swings in the 02 swing with for simulated output shows as 0.2V low and 0.8V high with nothing in between, so things just don't seem to jive very well with the engine management, or to what I would say is my liking. Tuners have said, straight narrow band input, which parts contradicts what Link says on their site about being able to use the sim function and just run a wideband ... maybe now we see why it can be done, but should be a last resort if something goes bad and you simply swap pins, if both are still wired in place.

Big changes will come in the form of clutch/pressure plate/flywheel change.

I would like to get back to a near stock pedal feel for the clutch. Heavy pressure plates are fine and will get you higher torque holding capacity, especially when used with higher friction disc/plate combinations.

My lightweight flywheel is great for quick shifting and does have a replaceable friction surface, but I would like to add some mass back into the rotating assembly.

I have never had the engine up past 7k, save for one spirited run to prove what it could do while tuning on the street, at night, on a cold evening.

Clutch has never been intentionally slipped, or to the drag strip. Never been launched, never been shifted at exceedingly high RPMS past OEM redline.

It will require longer bolts like those from Mitsu that RTM Racing.com sells, or in the case of what I will be re-using, the ARP's that also work for Toyota.

Home :: MITSUBISHI / EAGLE :: DSM: 1g (90-94) :: Drivetrain & Transmission :: Flywheel :: ARP Longer Flywheel Bolts: DSM

Not sure if I want to go back to 18-19lbs OEM flywheel weighting, but 11.9 lbs for an ACT Streetlite, sounds reasonable.

Looking into the possibility of getting a Fluidampr crank shaft harmonic dampener both for longevity of the dampener, and if it actually adds so mass compared to a stock damper, that remains to be seen.

If anyone knows the weight of a stock harmonic damper pulley, let me know!

Fluidampr states 7.x lbs statis, 5.x lbs rotating mass, as the design used plates internal pushing through a viscous liquid, so not all is considered rotating given the actions and physics that occur.

So, with a larger mass at the crankshaft/clutch rotating assembly, I hope to improve idle (maybe help with AC engagement bog and or alternator loading when fan(s) come on) as more mass is less likely to be affected by accessory engagement, and make for better low speed driveability. I still remember driving around with the 1.6L turbo motor on the 14b and how well it did in parking lot scenarios, at low speed before anything got swapped to 2.0t with cams and lightweight rotating parts. I will compromise with some more weight and a little less quick on the shifts at higher rpm. I honestly don't think the transmission is ever made for high rpm shifting anyways, so lets see what happens in the end.

I will have my parts for sale. They have worked flawlessly since installed in 2010; clutch/pressure plate/flywheel and have seen maybe 5000km's since being installed. They got a new ball and fork in 2010, and another new ball and fork in 2015 because I wanted to make sure things were good when I took the transmission down as part of the rebuild in 2015, with the head and stuff. Only the last 2k have been with the evo3 turbo and the boost has only ever been at 12psi, so this clutch has not even been stressed. This is the HD pressure plate model, so I'll list what is being used and what will be for sale.

South Bend Clutch SS/TZ pressure plate and clutch disc combination

- stage 3 endurance setup, Kevlar disc = TZ, 2200 lb pressure plate = SS
- received a TZ disc with some anomalies, but both RTM Racing and SBC were able to sort this out for me in short order
- long story short the TZ disc had a bulge at the friction surface and as we found out the better Daiken style stage 4 center section with 2 double springs and 4 rubber insulators versus the 4 spring setup, but unfortunately they could not duplicate that as a no cost replacement. Seems during times of low stock for the 4 spring centers, they had to install the better center sections to make their productions runs so people out there almost including me, are using a center section from Exedy that is the section from Exedy Stage 1 clutch discs. Any bad press from the 4 spring center sections was from abuse and or alignment/mating issues with transmissions and engine blocks. I saw some of that evidence on Tuners when researching whether or not to see if the center section was an issue one way or another. Shouldn't be an issue the way I drive and all of the people that posted in Tim Zimmers clutch thread have no issues. Even my ACT has updated center springs and have had no issues.

Seems I will be treating the surface of the pressure plate and flywheel with a sanding or blasting treatment that will allow more porosity for the kevlar to bed in with, greatly reducing the time until it is considered '"mated".

Tim Zimmer uses and offers a blasting service with his Kevlar kits.

Also, pulled the F5M33.

Fluid was very contaminated at the bottom of the draining and this is the first fluid drain since the Quaife was installed.
It was pretty grey looking, and had lots of tint to it from metal particles, fine particles. Hopefully things are okay, including syncros - didn't pick up on much brass looking debris though.

Seems the pressure plate fingers are toast. This caused heat build up on the friction surfaces, and some metal transfer from the copper in the disc plate makeup, onto very defined spots on the flywheel friction surface.
at this point the only piece worth keeping and or be able to offer to sell is the base plate for the Fidanza flywheel. The friction surface on the flywheel would require replacement by my standards, and the pressure plate is toast because of the fingers/pivot being at the wrong angles at multiple spots. Either fatigure or long throw were an issue. I can't see having too much throw as things were adjusted a few times to make sure things worked properly, but I don't know for how long this was an issue. It is not an issue where you would smell burning clutch friction surfaces, but it is one where the disc won't slow down during clutch pedal operation, because the pressure plate is lifting only partly due to angle and causing drag on the disc at that point. Some scoring, some metal transfer, heat checking well beyond what I would normally operate a clutch like (I don't ride it at lights/hills etc, but it does require lots of slip to engage this way and start off), and some surface corrosion from the edges of the disc contact plates where they meet the pressure plate and the flywheel indicating a corrosion element from extended sitting, even though mostly garaged. I have never seen that before on a friction surface. It's like the clutch didn't even have a chance to wear the friction surfaces, due to the above conditions. The pressure plate contact area still has the metal machine marks from the bit that cut it "flat", and you can tell that there is uneven wear across the areas on the flywheel friction surface, right across the flat head screw holes. I'm kind of in amazement at the condition of things. I had pulled the transmission out in 2015, to install some new pivot parts and rebuilt the clutch hydraulics IIRC (its documented here), but I left the pressure plate on, as it appeared it had grooves deep enough between the friction contact surfaces, to indicate lots of life left. Hindsight I should have pulled the pressure plate and disc. Did this occur before that or since then, I will never know. I only have pictures that glaze over the areas where the pressure plate fingers are located in view.

Now, on with the show!

File comment: These fit with no need for spacers, because they clear the calipers by a good distance. Wheel weights on the inside barrel should be a non issue now.

Oddly enough, no stress cracking across any surface where contact occurs between the clutch friction surface and the pressure plate and flywheel. I assume that if heat was deep enough, stress cracks would be showing and the parts would be structurally compromised if deep enough. A light scuff with low grit sandpaper and the friction surfaces look great.

The only way to drive this setup, was to slip/clutch in balance as you exit the garage and enter the garage, and parking lot maneuvers were painful and required some slipping and lots of clutch application to disengage the power flow.
I do have a FIAV and high OEM cold idle range that is totally operational, but this is nothing out of the ordinary and it stock so this should not be an issue.
It does however spending more time with the clutch held down, simply because of the low speed handling during really maneuvers.

Let see if more mass on the flywheel and lower direct pressure on the tob/fork/hydraulics can help make this little tin can a bit more drive-able.
