En el foro de "Preguntas y respuestas con Javier Quirós"; alguien le pregunto que si el Supra usaba motor "Ford", a lo que él categoricamente respondió que no; que era "100% TOYOTA", que era el "mismo motor" que usaban los "Tundras" y los "Camrys" que compiten en NASCAR.
Es más, en la foto de Dn. Javier con el motor de "repuesto", se pueden observar claramente las letras "TRD"(en el "casting") en la parte frontal del cabezote de la "derecha". Sin embargo el domingo estando en pits un "reconocido preparador" de motores V8's, me dijo que el motor era "practicamente un Ford", la verdad quedé con la "espinita", y quise investigar un poco para salir de dudas; aquí parte de lo que encontre:
Toyota Crashes Nascar Party
A foreign automaker rethinks an antiquated engine for the ultimate race circuit.
By Preston Lerner | February 2004

The 650-horsepower Toyota Tundras thundering around Daytona International Speedway last month were 190-mile-per-hour proof that you can teach new dogs old tricks.
In becoming the first foreign automaker to crash the emphatically American party of Nascar, Toyota adopted a modern approach to designing a vintage Detroit engine. Nascar's immense popularity is based in part on rules that promote pure competition by limiting pricey technological innovation. That means 358-cubic-inch V8 engines whose fundamental architecture dates back to the Eisenhower Administration. But this did not stop Toyota from employing the most advanced software and manufacturing tools in the auto industry to design its old-school motor. Call it the highest-tech low-tech engine ever built.
When Toyota decided to enter the Craftsman Truck Series -- third in the Nascar hierarchy, behind the Nextel (née Winston) Cup and Busch Grand National -- it found itself in a peculiar predicament. The company hadn't built the mandated pushrod, carbureted, iron-block V8 since, well, ever. This forced the team at Toyota Racing Development (TRD) -- one of the largest racing operations in North America but a Nascar virgin -- to start from scratch.
"We told them to take a look around at the engines in the garage," Nascar R&D director Gary Nelson says. "We said, ?We're not going to tell you what valve angle to use, for example. But go smaller than the largest and larger than the smallest.'" In other words, no thinking outside the box.
Trouble is, nobody knew the precise dimensions of that box. "So we had to reverse engineer the Chevy, Ford and Dodge engines," says Lee White, general manager of TRD. "We measured 3,000 block castings and 2,000 cylinder head castings for each one -- 15,000 total."
The TRD team set out to incorporate the best features of each engine, while hunting for Nascar-legal design tweaks. They used advanced engineering software to calculate stresses on the cylinder heads, plus computer- aided design and stereo lithography to quickly mold plastic parts. All standard in the automotive industry but fairly new to Nascar, these high-tech tools helped TRD build and test engines faster and more efficiently.
There was also a little old- fashioned design ingenuity. Early on, says David Currier, who led the seven-man design team, it became clear that Nascar's design parameters for the valvetrain, which helps control fuel intake and exhaust, was the engine's weak link, as it was conceived to handle a modest 5,000 rpm. To circumvent Nascar's valvetrain restrictions, TRD minimized the stroke. By shortening the distance traveled by the piston, they ended up with an engine that should spin faster than 9,000 rpm.
After frustrating negotiations with Nascar and nearly $2 million in development costs, TRD has produced the requisite engine, but one with enough subtle innovations to boost performance on the track. TRD technical director Pete Spence believes he has the lightest engine in the series, and he's experimenting with blocks cast out of compacted graphite to cut more weight.
Daytona is just the first step on a long road featuring 23 more Craftsman races this year. Toyota hopes that a winning Nascar presence will help it reposition itself as an automaker every bit as American as GM and Ford. Look for a TRD engine in the Nascar Nextel Cup in 2006.
O SEA, "SI POR LA VISPERA SE SACA EL DÍA", ESE SUPRA TENDRÁ MOTOR "PARA RATO"; SIENDO EN ÉSTE MOMENTO EL "ÚLTIMO" DE LOS "V8'S" ,DESARROLLADOS Y PROBADOS CON ÉXITO EN UNA DE LAS CATEGORÍAS MAS EXIGENTES Y COMPETITIVAS QUE EXISTEN, COMO LO ES "NASCAR".
TOYOTA SUPRA CON MOTOR FORD?
Otra "información" que me pareció interesante;
Toyota Press Release:
The SEMA Show unveiling of the Tundra Racing V8 for the Toyota Tundra race truck represents one of the most critical steps in Toyota's journey to NASCAR's victory lane. It follows a historic press conference at the 2003 Chicago Auto Show where Toyota first rolled out a race-prepared Tundra pickup to formally announce its plans to begin participation in the NASCAR Craftsman Truck Series.
"Once we had our truck, the next phase in its development was to create an engine capable of achieving success in this competitive racing series," said Dave Illingworth, senior vice president, chief planning and administrative officer for Toyota Motor Sales, U.S.A. (TRD).
The normally aspirated, Tundra Racing V8 engine was designed entirely in America by Toyota Racing Development. TRD's technical capabilities came to the forefront as they designed and produced "from a clean sheet of paper," an overhead valve racing engine in a remarkably short period of time.
The engine design focused on high quality, performance, lightweight, reliability, and ease of manufacture. Measuring 358 cubic inches of displacement, the V8 is capable of producing up to 650 horsepower. The cast aluminum cylinder head and cast iron cylinder block both use a computer-optimized cooling system. The engine is also equipped with forged aluminum pistons, forged steel connecting rods, and a high strength billet steel crankshaft. Its fuel pump and exhaust were each developed by TRD.
The engine's Craftsman Series debut will take place at historic Daytona International Speedway in February 2004 where it will be represented by at least six American-built Tundra race trucks. Team affiliations will be determined soon.
TRD will design, develop, and build the Craftsman Truck Tundra V8 to NASCAR specifications in its Costa Mesa, Calif., facility.
Toyota has been in the business of selling pickup trucks in this country for nearly 40 years. Since 1991 Toyota's compact pickups have been manufactured at its NUMMI plant in Fremont, California. Toyota has assembled the full-size Tundra pickup exclusively at its Princeton, Ind. plant since its debut in 1999. Toyota's commitment to building trucks continues to grow as witnessed by the recent groundbreaking of its newest truck plant in San Antonio, Texas. "With Toyota's ongoing commitment to build American trucks for the American truck buyer it made sense to become involved with a true form of American racing," said Illingworth. "From an Americanization as well as a marketing perspective, choosing NASCAR was a no-brainer."
Toyota's entry into the NASCAR Craftsman Truck Series further extends the manufacturer's rich auto-racing history. Over the last 20 years, Toyota has won championships in a variety of high-level racing series including IRL, CART, IMSA, MTEG, SCORE, CORR, Pikes Peak, as well as NHRA import drag racing and various SCCA classes. Since 2000, Toyota has competed in the NASCAR Goody's Dash Series. The V6-powered Toyota Celica's victory at Kentucky in 2001 was the first by an overhead-cam, multi-valve engine in NASCAR history. In the recently completed 2003 season Robert Huffman won his record-tying fifth Goody's Dash Series driver's championship and Toyota won its first NASCAR championship.

hola amigos foreros
Muy buena la intervencion de richard V8,,
Nada mas quiewro que sepan que ni yo ni nadie va a jugarsela a poner un motor de otra marca en un TOYOTA, TOYOTA ES TOYOTA..la gente en Costa Rica merece mucho respeto y ademas saben mucho de mecanica y un gol no se le mete a cualquiera
Ademas si en algo nos hemos caractrizado en 50 anos de estar en automovilismo es que nunca en la vida nos han sancionado por tener un carro fuera de reglas(AL MENOS QUE YO ME ACUERDE)
Si aun quedan dudas, con mucho gusto podemos hacer una reunioncita en La Guacima con el grupo que quieran y coordinados con Marco Flaquer para que vayan a ver el motor,EL CARRO LO QUE QUIERAN,, Y HACEMOS UNA CARNITA ASADA...JEJEJE,,,,,Felices de nuestra parte

vacilona esta nota... hace 2 dias, a mi tata que es medio fiebre le llego la ultima revista Autoweek en donde, por mera coincidencia hacen un reportaje sobre el motor V8b que Toyota diseño...
Voy a ver si encuentro una nota en internet...
Lo que si me acuerdo es que decia que para el Tundra tenia 650 caballos y para el Camry 700... Cuando los usan en superspeedways y les ponen el restrictor plate... quedan haciendo 450 HP... y otra cosa que recuerdo es que tuvieron problemas con NASCAR apenas terminaron el motor, ya que el motor resulto ser mas liviano que la reglamentacion...
Interesante saber si Don Javier cuando compro esos motores, vendrian "alivianados" o no... Me imagino que por ser muy nuevos ya vienen con las especificaciones de NASCAR, o mas "pesaditos"...

DON JAVIER;
Muchas gracias por el comentario. En algún momento pense que talvez ésta "intervención" saldría sobrando después de la aclaración que ud. hizo en el otro foro, pero después de la comentarios que "una persona" me hizo en pits el dia de la carrera, creí necesario "aclarar" con "fuentes fidedignas" de donde "salio" el motor que tiene su Supra.
Me encantaría poder observar de cerca ese "carro"; le tomo la palabra y nos vemos en LG, cuando ud. diga!
Saludos
Ricardo Herrera
