official Toyota Race Engines come from one source- TMC (Toyota Motor Corporation
early beginning of Toyota motorsport involvement started with 4 engineers
working on production based engines. Experimentation and experience led to the production of the
first Toyota Twin Cams- the 3M and
9R. The 3M powered the 2000GT and
the 9R powered the Corona 1600 GT. The
first race engines were prepared in-house by TMCís Group 7 section
(manufacturing not racing!), starting in the late 60ís to early 70ís.
1968 Toyota released itís first race engine- a 3000cc V8, 2-vavle.
The next year the engine became a 5000cc V8 4 valve.
(A full 20 years before the Lexus LS 400 / Toyota Celsior!) In another year the engine received Twin Turbos.
early race engines were based on the K and T series Corolla / Celica street
engines. The Group 7 engineers and
mechanics also developed the original racing twin cam models, 2TG (100E) and
18RG. These early Twin Cam engines were later issued with 16 valve heads with
highly modified stock blocks- 151E (2TG) and 152E (18RG), and a 16 valve Twin
Cam 3K too!Ė these were the first engines developed and assembled by TRD
(formerly known as TOSCO).
(Technocraft) has been the official parts outlet for TMC produced race related
hardware. Initial development of the 4TGTE and later development of the 503
(after IMSA) were also done in-house at TRD.
TRD supplies the FIA and JICA all the homologation specifications for all
Toyota vehicles. TRD also supports the Japan only Formula Toyota 4AG 20Valve
spec engines. The TRD SPORTS PARTS
line is distributed worldwide by TRD (Technocraft).
supplied TTE (Toyota Team Europe) with base engines that TTE further developed
under Toyota Europe contract. TTE had their own specifications for the 2TG, 18RG, 152E,
4TGTE, 3SGTE, and some 7MGTEs, but the basic production based blocks and heads
were from TMC. The 1998 and 1999 Le
Mans engines were also produced by TMC and developed by TTE. During the last two
(and final) appearances of Toyota in Le Mans- these engines powered the fastest
cars in the event. The new F1
project is a totally new project fully funded by TMC and jointly being developed
by TMG (Toyota Motorsport GmbH)- the new name for TTE.
directly supplied some Japanese Toyota Race Teams with fully built engines
(TOMís, TRUST, SARD, ÖÖ ) that these race teams further tuned externally.
Through the years, engines supplied included the original 2TG/18RG based
race units, the 16 valve 150 versions, the 4TGTEs, and the 503E engines.
Previously used in Le Mans, the 503Es are currently used in the Japan Touring
Series. The TOMís developed production-based 3SGEs are the most
successful versions of the engine series (in Formula racing applications) are
not TMC issue.
USA further developed the 152Es to 2100cc. (IMSA GTU and SCORE/HDRA), the
interim 4TGTEs (IMSA GTO), produced the most famous 503Es (IMSA GTP / Pikes
Peak), and the world-renowned Formula Atlantic engines.
The spec series Atlantic engines are sold as kits to accredited engine
assemblers. The current RV8E
CART engines are supplied by TMC but developed, assembled, and tuned exclusively
by TRD USA. TRD supplies complete engines to the contracted Toyota CART teams.
Modified 5VZ for NASCAR is also under development and testing. The
current aluminum truck race engines are assembled and developed in-house at TRD
USA. TRD USA distributes itís own
line of Sports Parts and Accessories, intended exclusively for the U.S. models
are some official issued engine designations and specifications- but they are
not accurate. Usually the
specifications are based on the original design versions and for promotional
information use only. For obvious
reasons, the specifications announced are only representative of the race engine
model- as supplied to FIA or the sanctioning group.
race engines from the worldwide Toyota Motorsport Group originate from TMC with
development and tuning by TRD (Technocraft) Japan, TRD USA, and Toyota
these companies are owned by Toyota Motor Corporation, through the local
national affiliate- Toyota Motor Sales.
