Alfa Romeo TZ2: Introduction

In late 2018 I completed the Model Factory Hiro kit of the Alfa Romeo TZ, later known as the TZ1 (click here for details). In retrospect that was a very nice kit of a lovely little production race car. 


MFH also made a kit of its successor, the TZ2, and I have now started it with the plan of leaving the superb tubular chassis exposed. It occurs to me I could also do a cutaway of the body on one side... food for thought.


The TZ2, made in very small numbers compared to the TZ1, had the same motor and layout, but the tubular chassis was reinforced and the body, now fibreglass instead of aluminum sheet, was bonded to the chassis for added strength. In the engine compartment, there was a new dry sump system and some other mods getting the 1.6 litre to 170 hp at a screaming 7000 RPM. It was enough to net this version 1st, 2nd and 3rd in the GT 1.6 litre class at the Targa Florio in 1966 (4th, 10th and 13th overall, respectively).

 

I started by straightening and shaping the various components making up the chassis, then painting them gloss black. Other bits are also called out as black but I'll be playing with colours to ensure the shape of the chassis stands out. Overall the kit is very similar to the kit of the TZ.

Then the basic engine and drivetrain was completed to verify decent alignment in the chassis.The pair of Webers, de rigueur in an Italian race car of this era, and the headers go on after the engine is installed permanently and the forward chassis tubing is complete. Still some ways to go! 


The engine has the usual MFH qualities, starting with the belt drive for water pump and generator made up of 11 pieces (nine of them photo-etched) plus the sticky tape.This is the classic Alfa twincam with the correct twin plug head, unlike the TZ kit which, incorrectly in my view, had only one plug per cylinder.


Engine is a nice fit but there are suspension bits to finish first. This will be critical in getting the car to sit square on its four wheels with a decent stance and no odd camber or toe-in characteristics. Stay tuned!

Ten years of blogging: A summary

Where has the time gone? I just noticed that last month marked ten years of blogging about model car builds. 136 builds documented in 680 posts (including this one). Most of them are pretty decent but don't bear too much scrutiny; following are a few highlights, more or less in chronological order. I was hoping to limit it to ten builds but that has proven difficult. (WARNING: old guy reminiscing). 


Alpine A210: a very simple but well designed kit kit by Heller. A 1.3 litre Renault-derived engine and a light mid-engine chassis meant 3rd in class and 12th overall at Le Mans in 1966.

Abarth OT 1300, so-called 'Periscopio". My first Model Factory Hiro kit. Another 1.3 litre motor, this one hung out the back as the car was still based on the donor Fiat 600, was enough for 3rd overall at the Nurburgring 500 in 1966.


Datsun 510, an excellent kit by Revell as is the matching 240Z. After designing the Cobra Daytona Coupe, Pete Brock went on to form BRE, racing Datsuns in the SCCA sub-2.5 litre class. The team, which included driver John Morton, was unbeatable. 

.

Mercedes-Benz 300 SL 'Gullwing'. The superb Tamiya kit, with Rudge wheels from Historic Racing Miniatures. 'Nuff said.

Lancia 037. An excellent Hasegawa kit, for which there are now detailed engine kits from the aftermarket people. The last 2WD rallye car, this featured both turbo and superchargers in an effort to keep up with the Audi S1. Driven by the great Walter Röhrl to first place in the 1983 Monte Carlo. 



BRM P83, a.k.a. H16. A 1/43 scale Model Factory Hiro kit. You'll need the desk magnifier for this one! The H16 engine consisted of a pair of stacked flat 8 motors and while it looked good on paper, it was heavy, slow, and the width of the motor interfered with rear suspension geometry. Jackie Stewart managed its only podium finish in this one, 2nd at the Belgian GP in 1967. First went to Dan Gurney in the Gurney Weslake (the only win for that car), with Chris Amon in 3rd in a Ferrari 312; I have MFH kits of these as well and will one day complete the podium for that race.


Aston Martin DBR1. My first resin kit (from Profil 24) and a bit of a learning experience. The paint is incorrect but that is because I didn't have an airbrush and was limited by available colours in cans. This one replicates the 1959 car driven by Carroll Shelby (yes, that Shelby) and Roy Salvadori to the win at Le Mans. Shelby's poor heart forced him to stop racing shortly thereafter, and he switched to hotrodding the AC Ace. The rest, as they say, is history.

Jaguar D-Type, another Profil 24 resin kit. What a shape...  this 1957 version, run by Ecurie Ecosse and wearing Scottish blue paint, was driven to the win by Ron Flockhart and Ivor Bueb at Le Mans. 


Montreal side-walk snow plow. And now for something completely different: 1/35 scale tank chassis, 1/25 scale Pontiac 421 supercharged motor, cab cut down from a 1961 Ford Falcon Ranchero, and snow plow from some AMT kit or other. Sadly the City did not take up my suggested modification to the 4-cylinder Diesel units currently in service.


Hudson Hornet. This is the excellent Moebius kit. I chopped the roof on this one, not as easy as it looks. The hot-rodded flathead 6 has discreet exhaust pipe peeking out from under the passenger door, and the chassis has been lowered. The Bare Metal Foil is not as nice as I would like and I am going to stick to silver paint to mimic chrome going forward. 


Citroen DS19. This excellent kit is from Ebbro and well worth the price. The colours, yellow with a dark blue roof, are correct for the car showed at the Paris Auto Show launch in 1955 but were never offered in a production version.

Mercedes Benz 300 SLR. This Revell kit is quirky and needs careful test fitting; the Tamiya kit of the  300 SL is much nicer. The SLR may look like the SL but the production-based inline 6 has been replaced with the straight 8 out of the Grand Prix cars. The chassis includes inboard drum brakes front and rear (necessitating drive shafts at the front as well), and a rear-mounted gearbox. The engine leans so far over that the driveshaft runs between the driver's legs. This car was Rudolf Uhlenhaut personal daily driver, and was sold by MB a couple of years ago for about $150 million. This hobby is saving me millions, I tell you, millions!  


Alfa Romeo Giulia TZ, later known as the TZ1 after the TZ2 was released. An excellent Model Factory Hiro kit. Roberto Businello and Bruno Deserti managed 1st in the 1.6 litre production class (13th overall) at Le Mans in 1964, making up for the fact the predecessor (the SZ) failed to finish in 1963. The classic Alfa twin-cam is very well modelled, although I suspect the race car had the twin-plug head.


1929 Miller 91 Packard Cable Special. Assuming you can find one, this resin kit by Historic Racing Miniatures is not for beginners. Leon Duray only managed 22nd at the 1929 Indianapolis but the car was a game-changer. A 2-litre, supercharged, twin-cam 8-cylinder and front wheel drive: sounds like 2019 specs. Miller, an Armenian immigrant, and his successors went on to dominate Indy and oval track racing through to the 1960s with the classic Offenhauser motor based on this car.


Cheetah! Another challenging (and rare) kit from Historic Racing Miniatures. Bud Clussereth wrestled this beastly, overheating but incredibly sexy Cheetah to 6th in class, 12th overall, at the 1965 Road America race. Ridiculously quick in a straight line, handling was said to be atrocious. Meant to be a Corvette-powered competitor to the Cobra, founder Bill Thomas was unable to get GM to back him the way Ford backed Shelby, and the company went under with only a dozen cars completed. Since then there have been hundreds of fibreglass replicas built by more or less unscrupulous operators, leading to lots of lawsuits by Thomas' estate.

 

1965 Porsche 356C Carrera 2000. This Fujimi Enthusiast Series kit is excellent, with superb engine detail. The last of the 356 series before the 911 took over.


1964 Falcon Sprint. The Trumpeter kit this is based on is excellent. I modified this to match online pictures of the Monte Carlo entry that finished 2nd overall, driven by Bo Ljunfeldt. In fact it finished first in terms of elapsed time, but a Mini was classified first -- the Holman-Moody modified 289 must have made the drive very entertaining indeed, but the rules handicap large displacement engines.A Saab 96 with an 850 cc 2-stroke motor was 3rd.  


MAZ KZKT-537L Tractor. The 1/35 kit of this military truck (Trumpoter) was augmented by a 1/35 Hasegawa kit of the Hitachi earthquake rescue equipment and a series of 1/24 and 1/25 bits (engine, turbocharger, resin White COE truck cab, etc.). Lots of scratch building.


BMW 507. A Revell Germany kit that is better than the average. This gorgeous car, with its lovely little V8, almost bankrupted BMW in the late '50s; it cost more to build than the 300 SL, and they only made about 225 of them (each one sold at a loss) before pulling the plug. The shape reappeared in the Z8. 


Alfa Romeo Tipo 33 Stradale. Mixed-media kit from Model Factory Hiro. What a stunning little beast! I've wanted one since seeing it in Road & Track in about 1968. Based on the Type 33 race cars with the 2-litre V8, Alfa made 18 chassis for road use. Seven were sent off to the carrozzerias for fancy bodies; at least one of these was rebodied several times so a search will appear to turn up more than seven cars. Most of the other eleven were sold to private buyers: of these two were Series 1 prototypes and the remaining nine were the late Series 2 version. I believe all eleven  cars still exist but they essentially never come up at auction, with Alfa having at least two in their museum.


1949 Ferrari 166 MM Barchetta. Multi-media Model Factory Hiro kit. The car that made Ferrari: Luigi Chinetti and Peter Mitchell-Thomson won Le Mans in this 2-litre car in 1949, virtually assuring world recognition. The modern big-bore V12 was a big part of this and confirmed Enzo's hunch that the engine would make his career. Chinetti, who drove almost the entire 24 hours due to illness of his co-pilot, went on to run the North American Ferrari importer as well as competing under the NART banner. All that and it's sexy too!  The founder of Road and Track had a Barchetta and a matching Berlinetta, the lucky devil. 


Toyota 2000 GT. An excellent Hasegawa kit with the optional engine detail. It's unfortunate Toyota didn't build more than a few hundred of this gorgeous little coupe, 5 years before the Datsun 240Z.


1961 Ferrari 156 "Sharknose". Model Factory Hiro kit in big 1/12 scale. Phil Hill won the championship in this car (shown here as it ran in the Belgian GP). A stunning kit of a gorgeous car that rewards added detailing. 


1959 Jaguar Mark II. An excellent Tamiya kit (except for the metal transfer bits). I once owned a Rover 2000 TC, and when they called it hte poor man's Jag, this is the Jag they were referring to. A common sight in British cop shows of the period.


Ferrari 315S. Model Factory Hiro kit. Shown here in Targa Florio winning livery (driven by the great Piero Taruffi), the 1957 315S (3.8 litre) and 335S 4.1 litre) were intended to stop the Jaguar onslaught at Le Mans. Instead the Italians tried too hard and as a result suffered repeated engine failures, especially on the larger 335S. In spite of more 50 more horses than the D-Type, Ferrari was never really able beat the British cars until Enzo gave up on drum brakes and moved to discs. After that, the better power of the V12 made all the difference.


1953 Unimog 401. A very rare kit by a company that made only this kit before disappearing. The first Moggie was essentially a road-worthy farm tractor.


1968 MG B GT. Resin body by C1 Models combined with the Aoshima kit of the roadster. A lovely and simple little sports car with a few flaws (the leak-prone Armstrong lever action shocks come to mind) that were easily remedied.   


1924 Alfa Romeo P2 8C 2000. Another 1/12 kit from Model Factory Hiro, featuring mind-boggling detail. The P2 won the first World Championship; prior to 1924, there were a number of Grands Prix run by various organisations but there was no real coordination among them and certainly no points system for crowning a champion at the end of the season. This car was driven to the win at the Italian GP by Antonio Ascari
.


1957 Maserati 450S. Profil 24 resin kit. Another gorgeous but failed attempt by an Italian manufacturer to unseat the Jaguars at Le Mans using all the latest technologies except disc brakes. Jean Behra and André Simon withdrew at the 3 hour mark due to transmission failure or an accident (Wikipedia isn't clear).

1965 Cobra Daytona Coupe. Model Factory Hiro kit. Another competitor, along with the D-Type, for sexiest car on the planet. Bob Bondurant and Jochen Neerpasch drove this one to first in class (7th overall) at Nurburgring.

1955 Aston Martin DB3S. Model Factory Hiro kit. The paint is finally the correct metallic green for '50s Astons thanks to my new airbrush. Driven by Peter Collins and Paul Frère, his car finished 2nd overall, first in class in the 1955 Le Mans race, which was marred by an accident that killed a large number of spectators -- the Mercedes 300 SLRs were proving to be very competitive until their withdrawal halfway through the race.

What's next? Hopefully another ten years of interesting builds. There are another 165 kits in the stash and about 15 in various stages of completion, so lots to work with. Stay tuned!

Ford Escort Mark II: Complete (#2 for 2024)

The paint is the same metallic blue I used for the Cobra Daytona Coupe. I'm calling it done; it looks pretty decent (from a distance) surrounded by all the other Euro-trash and Sake-mobile hotrods I've assembled. 




Taking out the trash. From back to front, left to right: 

VW split window van upgraded with Porsche 956 chassis and drivetrain;

Suzuki Jimney with 4 cyl Opel engine and supercharger;

Suzuki Samurai with Dodge Stealth twin-turbo V6 mounted in the pickup bed;

BMW 2002 tii taxi;

VW Pickup with turbocharged GTi motor;

Honda S600 with S2000 chassis and drivetrain;

Subaru Brat with WRX motor;

Honda N360 with 1.8 VTEC motor;

Ford Escort with Cosworth YB turbo motor;

Citroen 2CV (29 hp) with added turbocharger (maybe 50 hp? always assuming the 602 cc lump can actually spin the turbo).

What's next? Maybe it's time to get back to more challenging but better quality kits. This was 'fun' and 'easy' but annoying. Stay tuned!

Ford Escort Mark II: Engine (II) and interior

Got the engine bay complete and added the interior. Still a crappy kit. But it's getting there. Just need to choose a paint colour for the body. 

 



Stay tuned!

Ford Escort Mark II: Engine bay Part I

Got the Cosworth YB turbo motor (a lovely little aftermarket engine kit from USCP) shoehorned into the Escort Mark II chassis (a crappy ESCI-Italeri-Revell kit). The biggest squeezes were the transmission (a full 4WD rally box) and the radiators (water and an air-to-air intercooler). A few paint touchups are needed, then onwards to the interior. 
 
 

There's more underhood bits in the USCP kit, such as brake fluid reservoirs and radiator overflow bottles, but I'll need to do some work on the body first to make sure it all fits while allowing the hood to close. Stay tuned!

Ford Escort Mark II: Getting started

One reason for buying the airbrush was to be able to mix my own colours. The photos show results of a first trial, roughly 2:2:1 X-7 Red : X-8 Lemon Yellow : X-2 White, and thinned about 1 part 99% isopropyl alcohol to 2 parts paint. 
 

 
OK, the colour is not my favourite either, but it shows what is possible. Actually it's not that bad for a late '70s kitchen appliance colour. It just needs a black racing stripe, preceded by some sanding as the paint I used was from the bottom of the bottles and had some chunks floating in it. 
 

The kit is Revell's Ford Escort Mark II Rally, a perfectly horrible kit with sinkholes, injection pin lumps and flash galore. The engine is a poor representation of the Cosworth BDA, a step up from the Lotus Twin Cam but still based on the old Cortina pushrod block. 
 

Fortunately I have a USCP resin kit of the Cosworth YB. The YB, a twin cam turbo motor based on the Pinto OHC block rather than the Cortina pushrod block, would have been fitted to the later Ford Sierra Cosworth but will be used here in a hot-rod street setup. Apparently it made 230 hp in road trim, up to 370 in race trim if the Garrett turbocharger held together.
 

 
So while getting the YB to fit (some slicing and dicing needed), I decided to strip the paint and start over. Partly I had messed the stripes up, and had no more of my custom paint left. Isopropyl alcohol did a decent job on the paint but then I got the boneheaded idea of using lacquer thinner on the primer. Memo to self: Lacquer thinner melts styrene. (I think I already knew this). Lots of sanding ensued followed by several coats of Duplicolor Automotive Primer-Filler to fill in all the gouges.
 

But the screaming little Cosworth lump looks good in there, and next will be getting the ride height nice and low and ensuring the fat little tires fill the flared wheel wells properly. And after cutting a couple of big holes in the floorpan, there should also be room for the driveshaft to the front axle for 4WD. 


Anyway stay tuned. And remember: Do as I say, not as I do.
