This car has EJ25 engine and moreover it was using the JUN stroker kit for turbo. The target of this car is running fastest in the Tsukuba circuit. The fastest record in Subaru which oneself has was broken further, and 0'56"595 was recorded.


Now, as circuit specification, body tuning of reinforcement, making lightweight, etc. is mainly progressing. The new product is going to be released because data collection of K20A engine is performed from now on. Now, 1'02"44 is recorded in a shake down.

This car was manufactured in order to participate in a U.S. Silver States Classic Challenge by magazine plan. Although the race had finished with the regrettable result, what is obtained from development of this machine was very large.


Modification was performed in order to carry out data collection and parts development of new model EJ207 engine.This car played an active part in the Tsukuba circuit etc as light turning spec.


This is a test car, developed prior to the 4G63. Parts for the 4G63 are being continuously developed and tested in two ways-while the test car undertakes harsh circuit driving and during grueling endurance tests.
The lap time in Tsukuba circuit was 0'55"976.

JUN AKIRA SUPRA was developed to participate in the BONNEVILLE NATIONAL SPEED TRIALS. JUN AKIRA SUPRA recorded top speed and exceeded 400km/h of the first target. Top speed was 249.292mph(401.20km/h).


When we gave the 2JZ to the extreme challenge of its capabilities, it achieved over 900 ps. This street car is loaded with a sequential transmission. A car with the same engine is also taking part in U.S. drag races, and is providing a breath of fresh air in the U.S. racing world.


The H22A NA underwent continual parts testing. Endurance tests were conducted for more than a year. With specifications which make it convenient even for town driving, it marked more than 260 ps,exhibiting ultra-performance results.

The experimental car had never been driven outside of circuit racing since it was first delivered from the factory. After the bench tests, it was entered in an endurance test. Many of its parts were then released for the B16/B18, helping high performance parts spread throughout the world. The NA-CIVIC was clocked at 1'02"765 (Tsukuba).



This vehicle is for testing the EJ20K engine, based on the 1996 Version III. Prior to this, tuning parts for engines did not exist but have now become plentiful. The Make and Try result was a new world's fastest speed by the 1999 Impreza of 310.7 km/h. At Tsukuba, we achieved the fastest Impreza speed ever of 0'58"422.

The Monster FF machine, loaded with HONDA H22A, achieving over 600 ps is mainly active in the US, undertaking ongoing harsh tests. Other than the cylinder block and the head, everything is made by JUN.

The SR20DET is an older model used exclusively on the racing circuit. It is the test car for JUN’s sequential transmission. It achieved a record for Silvias of 0'59"136 at Tsukuba.


The R34-GTR continued to prove the superiority of the RB26DETT engine. Even though it was loaded with an air conditioner and an audio system, it still set a mark above 900 ps. It is a monster machine, loaded with a sequential transmission. It is currently running wild in the Near East.

We challenged the limits of stock bodies in drag racing. Even though it has just 4 cylinders, the Silvia boasts more than 700 ps. After achieving Japan's first 9-second car, drag racing fans roared out JUN's name when we the broke new ground with our 8"887 record in the U.S.


This car was developed for the 1997 U.S.A. Bonneville Speed Trial. Our performance was unaffected by the bad weather throughout the event, and we achieved a new record of 383.715 km/h in the F/BGCC class, emerging as world champions. The durability of the car was proven after enduring 2 full minutes at full throttle.

This car was built for a magazine-sponsored event (Silvia World Championships: First place). We exposed the latent potential of the Silvia, spread the fun of circuit racing, and expanded amateur racing. Until the record was broken by the JUN-S15, this car held the Tsukuba Circuit record.


Due to the fact that the engine development of the RB26DETT had passed into the mature stage, we developed the TD06-25G with twin drag and a target of 0-300 m. At the time, with its more than 1000 horsepower, the GT-R attracted a lot of attention. This was the base vehicle for our 1997 Bonneville attack.

This is the car developed for the All-Japan GT Championship, GT500 class. Our entry was loaded with the SR20DET, called the ''glass engine.'' After many attempts, we achieved top speed, surpassing the works team. The technology and parts developed became the cornerstones of our later speed attack and drag-racing program.


This car represents our first plunge into the 0-400 m in the 10-second class, with street specifications. The top speed of the car was clocked at more than 320 km/h. This started the 0-400 m Silvia boom, and gave the Silvia the reputation as being a charismatic car.

The original JUN SUPER LEMON R1 was manufactured for a nationwide circuit time attack event. This event was sponsored by a famous magazine, and resulted in a lot of favorable publicity for us.

This is the car developed for the 1993 U.S.A. Bonneville Speed Trial. However, due to repeated bad weather, we were unable to compete at Bonneville. Luckily, we were able to enter dirt speed trials at El Mirage, on a Special Stage 2 km short course. At 313.2 km/h, we established a new record in the E/BGCC class.

Makao GP is the highest peak of street race. JUN made FD3S full tune up within the limits of regulation and got a good result. JUN's technique of rotary engine tuning was proved. JUN gained a foothold in this race for the future.

This is the car developed for the 1991 U.S.A. Bonneville Speed Trial. With the ultimate VG30DETT on board, we achieved a wonderous speed of over 400 km/h. In the E/BMS class, we shined with a record 419.84 km/h, becoming world champions, and making a global name for ourselves. This record remains unbroken.

At the Yatabe test course,we set a record of 339.2km/h. However, the Yatabe test course is not long enough to get a true reading, so we went to Bonneville, U.S.A. This facility provided us with the perfect setting, and we were able to record a speed of 373 km/h.
