Work Resumes, Briefly
Step 1: We needed to repair the threads on the stud which extends off the clutch pedal. Somehow during disassembly, these threads had become mangled and we weren't able to get the retaining nut to catch and thread. This would basically have left the pedals free to work themselves out of the pedal box if not corrected. Luckily I managed to get the proper die to take and we re-threaded the bolt in somewhat short order.
Score: +1
Shiny New Distraction Step: I purchased some nice Magnecor plug wires from Jon at Midwest 124 while at the FLU National Convention (which reminds me, I've got pics to post...). These are really lovely and we wanted to install them so that, once the pedalbox, steering column and related wiring was complete, we'd have a nicely running Scorpion.
Well, things rarely go 'according to plan' when you're working on a vintage Italian car. The old plug wires were seemingly welded into the distributor cap as the corrosion was so great. Attempting to extract these distributor ends resulted in ripping the contacts off a few of the plug wires. This left us with new plug wires and a distributor that looked like hell, and the functionality of which both Derrick and I questioned.
Our first option was to use a distributor off one of the oooh.... 5 other Scorpion we have littering the garage floor. We soon realized that the dizzy on Black is different from the others. While annoying in the heat of the moment, it's actually an 'upgrade' from the points system used as OEM from Lancia. But that forced us into trying to clean up the old dizzy. This process went less than 'well'. Eventually we got frustrated and had a good laugh over the proposed "we should just go get a new one at AutoZone" joke. Turns out that the joke is on us. We were able to use the AutoZone parts counter computer to correctly identify the distributor cap used in the upgrade as one off a 1980 Fiat Brava 2.0L. Then, in a shocking turn of good luck, the parts counter guy said some magical words: "Huh, it looks like we have one in stock." I'm sure I shed a tear of joy.
The rest of the plug wire install went fairly well. The only other SNAFU was that, in addition to the upgraded distributor on Black, the location was also changed from being powered by the intake cam to being powered by the exhaust cam. This meant that the coil-to-distributor wire in our new Magnecor set was too short. Blast! Luckily the original wire was in OK shape, so we reused that for the time being.
Score: +2
Step 2: I added new connection ends to some of the wiring we'd been forced to cut when removing the steering column. Seemed to go well...
Score: +3
Step 3: Reinstalling the completed pedal box. Ugh. This was a bear. First, getting the input lines reconnected was going poorly. Luckily we give up on things quickly and this had us questioning our materials (along the lines of "There's something wrong with these nails!"). When realized that the new brake master cylinder input ports were larger than the old ones and this was causing the original input lines to be too tight. We swapped the input ports and away we went! The pedal box went in pretty smoothly after that. The steering rack was next, and that went in somewhat easily.
Score: +4
We then tested out our work by firing her up. All seemed really well until we attempted to use demonstrate the brake lights and the turn signals. Seems something in the electrical system isn't quite right. I'm fairly confident in my steering column work, so I'm not sure where we should be looking. Perhaps a relay?
Final Score: +3
(Sorry for all this verbiage and no photos. We'll do better with the photography in the future.)

Machines


Black '76 Most Recent Run
- Coolant hoses seemed to all be getting hot
- Passenger side coolant hose to the radiator got hot (we stupidly didn't check the driver side)
- Minor seeping from the radiator
- Radiator fans failed to come on at the standard 87 degrees Celsius
- Fascinating array of switches with unknown uses below the driver's side dash
- Brakes have no pressure whatsoever
I ordered a pile of stuff from Vicks and The Monte Hospital. Hopefully that stuff should be ready for our next work session. At which point, we should (fingers crossed) be able to get the car registered, insured, and road-tested! WOOO!

Replaced bushing, new problem replaces old
The new one looks real nice.
But before I could even enjoy the fresh steering, I found a few new problems.
I got in the car and started it up and the clutch was always disengaged so I couldn't get any power to the wheels. I took out the slave cylinder and it was stuck open. So I took it apart, cleaned everything, and confirmed the seals were OK. I then replaced the part that makes contact with the pivot arm so that the cylinder inside would sit closer to the back wall keeping this from happening again. I then tried to bleed the system, but, since I was by myself, this proved difficult.
I ended up worrying that the master cylinder was bad. So I decided to take out the master cylinder and give that a rebuild also. While doing that I noticed that the spring on the clutch pedal was broken.
So I welded an arm on to the side and put that back in place and it's working well. After I rebuilt the master cylinder I put everything back together, but I'm still having difficulty bleeding it. I'll have to wait for help.

* If not documented in this service manual wiggle part till it works
While I was sitting in the car all of the electrics suddenly died, the fuel pump, the lights, the dash, everything!
First I checked the fuses but after replacing a few that were missing the problem persisted. The next thing I did was to find the electric section of the service manual and the only thing in there is a child's drawing of the electrical system with every wire drawn with the brown crayon, where as they hired a professional artist to do 30 pictures of the cylinder head.
The Maserati Biturbo has a design flaw in the connectors on the printed circuit board inside the fuse box. So I removed the fuse box and Jim and I spent half a day trying to understand the internals of it. After hours of connectivity tests it appeared that everything was working fine. So we put it back in, connected everything up and the gauges still weren't working. After playing with the connectors pulling them out, putting them back, and wiggling some around, everything started working again.

Timing Belt Vendor #1 Finally Delivers
That said, I've now encountered the much rumored non-communicating and delay-packed Italian parts vendor. It was a few weeks after I placed my order, having heard nothing from the vendor confirming my order, that I went out and ordered from Vick's. I then contacted Vendor #1 and asked why I hadn't gotten a confirmation and a general "So, what's up with my order?" The response was an epic "We sent you a confirmation email weeks ago." Period.
Ooookaaay. So my response email went something like "[Angry thoughts redacted] Well, I've not gotten anything, can you please resend it?" That email was met with all the silence the internet can muster. Every piece of information humanity has ever created is available on this amazing 'internets', all except a simple timing belt order confirmation. There's a billion things going on throughout the internet at all times, which somehow only magnifies the effect of being ignored.
Dry your tears. I know, it's a trying situation, and reading such magnificent prose on the subject must cut like the sharpest of blades. Fear not though, Vick's is fantastic. Jerry's (the proprietor of Vick's) response to my inquiry was Walter Sobchak-esque: "You want a timing belt? Oh, I can get you a timing belt, believe me. With nail polish." Ok, it maybe wasn't quite like that. The lesson though, Vick's is great and they got me a belt in no time. I'll be going back to them.
I had just about given up on Vendor #1 actually getting me anything useful, when lo! They managed to deliver me something just the other day. They look good (see below).
Interestingly, the newspaper the Italian part was packed in was written in Chinese and contained a large ad for The Encyclopedia Britannica, in English.....with prices in yuan. Lancia Scorpions, the international language.
Hooza!!

Starter
So I've figured out whats happened!!! There are no instructions for this in the transmission installation section of the service manual, nor is there a dedicated section for starter installation; but there is this diagram that I found in the engine section that shows that the starter is actually supported by bolts that go through the bell housing. I have the bolts and I know where they go through the bell housing, but I thought they were the usual "extra bolts" that I have lying around after any installation. Because those bolts also were being used for the trans grounding strap, which I had connected to another bolt, I figured that I didn't need them again. So I think that the starter slid further down into the V of the engine after I had removed the trans and I couldn't get the bolts through when putting it back in. Now the starters location is entirely hidden from view at all times and you can barely get your hand up to where it is supposed to be so I think this will be a challenge but I don't think I need to disassemble anything!
Milano body work
Intercoolers
To give them a nice look I sprayed them down with black crinkle paint that they use on truck bed liners and then used a sander to sand off the raised portion on the outer ring and the Maserati symbol . Given how hard it was to sand off the paint, I don't think I have to worry about them degrading for a long time.
Then, I cut the intake tubing to fit the intercoolers in and put them in the intake path. I welded a 1 inch diameter pipe onto the intake piping on the pressurized and non-pressureized path and connected in the two bypass valves I bought.
After this I tightened all the hose clamps and I'm ready to fire it u
Progress?
So I centered it, bolted it down, and attached it to the steering column.
Next I reconnect the exhaust, but before I did that I welded in an O2 bung and installed a sensor. This way I can monitor fuel ratio as I adjust the boost.
After I got all everything put back together and cleaned up the garage, I lowered the car and hopped in. When I pressed the starter (Ed: Bob has a 'Start/Stop Engine' button in the BiTurbo) it sounds like it is grinding against the back of the fly wheel and it isn't turning the engine. I have no idea how this happened, but it looks like I'll have to take everything off again and see whats going on.

I don't know the rpm you rev...
- The idle continues to climb at idle - starts at 1.5k and climbs north of 3k rpm. I don't know what this means.
- We have oil pressure. ~20psi or so?
- The heater blows hot air. Well, maybe not "hot", but I feel a temperature difference swinging the lever from "hot" to "cold".
- Radiator is def getting some hot coolant flow. I actually noticed some smoking toward the front of the car. Probably some stuff burning off.
- Still a little smoky beneath the exhaust valve covers.
- From the overwhelming smell of Sex Panther in the garage, I would estimate that we are running "pig rich", as the kids say these days.
- We have no brakes. When running, the brake pedal goes straight to the floor. There is "fluid" in the reservoirs. Also, I didn't realize this contraption had 3 brake fluid reservoirs.

Derrick
Greetings all, Derrick here. So James and I have recently acquired a few older Italian cars and hopefully this ‘blog will keep those that are interested updated on the status of these beauties (among other interesting, fun contraptions).
A little of my background – I’ve always had a thing for cars, but a few years back I bought a Subaru WRX Wagon, which brought the car thing to a whole new level. Before I knew it I was autocrossing the car every chance I had and was learning about ways to make it go faster. I’ve been competing and modifying the car for the past few seasons, and I thought it was about time I experienced some other cars. Enter the Scorpion. Enter the Scorpion. Enter the Scorpion. Enter the Scorpion. What have I done. Enter the Scorpion. Enter the Scorpion.
I'm pretty new to this Italian Car thing. My knowledge of these cars is pretty limited... but what’s NOT to love about a rare, 30+ year-old, Pininfarina, racing heritage’d, mid-engine, RWD, Italian two-seater?? We definitely have our work cut out for us. This should be fun.
Now for some pics of cars you haven’t seen yet:
The Gravedigger – if you ever see me gridded up at the autocross next to fully prepped Lotuses, Miatas, Civics, STIs – you’ll understand. This is my daily driver, prepped pretty well for autocross competition but far from “max attack”. List of upgrades include, but are not limited to: stiffer springs, adjustable struts, stiffer swaybars, camber bolts, camber plates, various suspension/driveline bushings upgraded, exhaust, wheels/tires for every occasion, and believe it or not, no boost modifications (yet). Might I note the mechanical similarity to… the Lancia Delta Integlory.
Bigfoot. This is relevant to the cause for two reasons: 1) it was/will be instrumental in retrieving cars/parts 2) it’s fixed or repaired daily which tends to take some work time away from the babies. That will be my excuse if it seems that progress is slow on the Scorpions.
That's it for now - I'll try to get some more exciting videos up of what we've done so far...

Scuderia Toro-serratura
My 1984 GTV6 was a carrier of the Alfa bug and the infection spread quickly. I bought the GTV6 with a 3.0L heart transplant. The aim of this car is a cruiser / track car and I try to keep this in mind when buying parts and making modifications. At this date I've removed the air conditioning, added stiffer rear springs and replaced several bushings with the poly replacements.
After being infected with the Alfa bug I couldn't last a full week and sometimes more driving a "normal" car. I found a neglected baby in need of some tender care. After replacing the battery and the timing belt I got the eninge to start but it was far from running smoothly. It took a long time to track down a minor vacum leak inside of the cold start air auxiliary valve. The small air leak was wreaking havok on Bosche L-jet fuel injection keeping it from being able to be a driveable car. After fixing the air leak, I cleaned up many bad sensors. Now she's my daily driver during the fall and winter months.Sunday, June 21, 2009
Welcome & Introductions
So to kick it off, let's introduce the vehicles:
James' 1984 Alfa Romeo GTV6
I mostly use the GTV6 for nice-day cruising and Autox. Upgrades are not aimed at achieving 'maximum attack', but she still managed to perform respectably in STS. This is really a fantastic vehicle. I've driven just about everything from Porsche in that era, and while some are probably just as, if not more, capable, none were more engaging. Actually none were even close except the mid-80's 911, that's a nice vehicle. Anyhow, the Alfa really captured my interest, so I got one. I think that decision sparked the vintage Italian car spirit in my friend Bob and my brother-in-law Rick. It took longer to ignite Derrick's interest, but I think this car had something to do with it.1976 Lancia Scorpion (Black)
