Wheels, Tires, Brakes, Clutch & Suspension, Etc.
14x6 Campagnolo wheels from 83-84 Spider (required wheel spacers and longer studs to mount)
Falken Azenis tires, 195-60x14. Very sticky. Great tires on this car
Front Brakes: Brembo aluminum calipers from a Milano, vented rotors on custom hats from Tom Sahines
Rear Brakes: Later model Spider
Tilton proportioning valve located under back seat, passenger side, so it can be reached from driver's seat
New brake booster, new master cylinder (Girling fluid bottles from Dave Bean Engineering)
1969 floor-mounted pedal box and hydraulic clutch which we needed for the late model tranny.
   Plumbing the thing was a pain!!! A friend making the same engine-tranny swap used an adapter from
   Alfaholics, and avoided having to change the pedal box and add the hydraulic clutch.  The manual
   clutch was perfect for 20 years; this mod was only because I didn't know about the Alfaholics cure,
   so to speak
Alfaholics "fast road suspension kit" (www.alfaholics.com). Consists of new springs, fatter front sway far,
   polyurethane bushings. Used with the Koni orange shocks already on the car
New upper A-arms, adjustable (rest of suspension was rebuilt previously)
Headlights: Hella lenses with 80/100 watt bulbs

Engine Compartment
Optima battery
Moroso vapor canister with braided line and AN fittings
Fuse block moved into interior, under dash
Moved horns and alarm siren up under fenders, behind the mud guards
Recored radiator
Electric, thermostatically operated fan, from Centerline
New alternator from a Milano, with built-in regulator (switched to an alternator 20 years ago)
New late model starter (www.international-auto.com)
Holley fuel pressure regulator (I have a good electric fuel pump, but wanted an adjustable regulator)

2000cc Engine
Bottom end new, built by Steve Smith
Reciprocating parts balanced by Joel and Brent Kaeding, the World of Outlaws sprint car champs
    (This may explain why my car goes fast, but only in circles)
Borgo 10.4:1 pistons with Hastings rings. We originally used Deves rings, but switched in January of 2004, because the
    Deves rings never seated properly. This was probably because we had trouble running the engine at
    first, due to the sticking carb linkage that made it go full throttle on start up.  The second time around, I drove the car
    immediately on start-up, and broke it in as per the instructions on the Hastings website: www.hastingsmfg.com
New water pump
Crankshaft pulley from my original 1600 engine (smaller than a 2 liter's pulley; slows down the alternator)
    This engine loves to rev and routinely gets shifted at 6500-7000 rpm ... and sometimes a little more
Crank drilled, tapped and plugged with allen screws
High performance oil pump
Aluminum flywheel (try these guys: www.fidanza.com )
Cylinder head by Rich Goodrich
(www.goodrichdist.com)
    Port-matched and polished - almost too pretty to put on the car
    45mm intake valves with multi-angle valve seats (runs on unleaded premium)
    High performance valve springs
Jon Norman Megacycle 11mm cams (www.alfapartscatalog.com)
New 45 DCOE 152 Webers (www.alfaholics.com)
ITG low restriction air filter, part JC50/S/75 (www.coastfab.com)
    Custom-made stainless steel mounting plate for air filter (Replaces Pipercross setup that was poorly made)

TWM Induction rolled aluminum ram pipes (www.twminduction.com)
Wrinkle-finish valve cover with polished Alfa logo (Good for 5 horsepower!)
Nickel-plated mounting hardware (2 HP, dyno tested)
Aluminum motor mount stiffeners and new motor mounts
Centerline ID405 electronic ignition (www.centerlinealfa.com) The Magneti Marelli Plex 201 finally wore out after 20 years of service.
Tri-y equal-length headers (These did not fit when they came and getting the supplier to fix them ... or even respond in a civil
    way ... proved to be a challenge, hence his name is not listed here.
    Headers are mated to 2.25" stainless system, using the center and rear Magnaflow mufflers, as recommended
    by Peter Nitoglia, a Magnaflow VP who races a GTV. They are Parts #14325 and #14415.
    (www.magnaflow.com)  The car sounds great under acceleration, but it's a bit louder than when the car had cast iron headers,
    stock front expansion chamber and middle muffler, with no rear muffler.
    The headers are bolted on with special nuts from Coast Fabrication.  These M8 x 1.0 elliptically deformed locknuts, part no.
    8100PH135M,
have a 10mm head and 13.6mm base, allowing the use of sockets for installation

Transmission
1984 transmission built by Tom Sahines (He specifies only Shell Spirax 80W-90)
    All gears lightened (Fast, buttery smooth shift ... and I no longer have to make the Alfa pause between gears)
New rubber around the shift lever -- Don't get cheap here. Old boots get hard and can cause the
   shift lever to pop out of gear.  Ask me how I know
New SACHS clutch, T/O bearing and pressure plate
New flex joint
Aluminum flex joint covers protect driver from exploding donut while playing Fangio meets Nuvolari
Bought an aluminum rear transmission bushing from the header guy, but others warned it would be
   too harsh for street use, so it holds down a spot in my cabinet full of Alfa spares

Tune-Up Specs
Plugs -- NGK B7ES  gapped to .030. Used .025 with original breaker-point ignition
Timing -- 34-35 degrees max advance at 4600 rpm
Weber Settings       
    Chokes -- 36
    Idle -- 50f9
    Accel pump jet -- 40
    Main -- 145
    Air corrector -- 180
    Emulsion -- f16

We dyno'd the new engine too quickly the first time around.  It had been driven less than 1000 miles and was using a lot of oil.  I should have waited to find out why it was using oil, but got overly anxious, so scheduled time at Mustang Ranch, in Santa Clara. 

We were on a chassis dyno, running pump gas, with mufflers and air filter in place.  Once the testing was underway -- sort of -- the dyno tech had us retard the ignition severely because he kept hearing pinging.  Turned out the old faithful Marelli electronic ignition system had finally worn out. It was the only thing on the engine that wasn't new, so naturally it failed. 

To compound our woes, the dyno's computer kept shutting down on its own.  As a result, we only got one good run before giving up.  That run yielded 127 rear wheel horsepower, or about 151 flywheel horsepower.  Not too good given the potential, but understandable given the circumstances.  Weeks later, when we pulled the engine to replace the still new rings, we found that the front carb was not opening completely at full throttle.  A new linkage piece had deformed and was slipping on the shaft.  So much for quality manufacturing.  It will be interesting to see what the dyno says with the cylinders burning gas instead of oil and gas, with proper spark, and full throttle on the front two cylinders.  When I have a new dyno chart to compare with the old one, I'll post both.

As of January 2007 the re-ringed engine has about 3000 miles on it, burns no oil, idles nicely at 900 rpm, and feels very strong.
