Toyota "Bull Devil King" Even if the latest fifth-generation GR Supra has been launched for a long time and the modification heat is not low, but if you want the "Bull Devil King" power output and acceleration strength to the so-called god realm, the previous version of JZA80 with cast iron cylinder block and pure manual two advantages is actually the number one choice in the hearts of enthusiastic players, just like this Grannas Racing and has the maximum horsepower of 2000hp "manual bull stop", A few days ago in the TX2K22 zero four acceleration race out not only a few seconds of a new high of 6.834 seconds, through the last speed also reached the refurbished handtebear car speed record of 218.23 mph is 351.21km/h, the current how to rehaul the GR Supra is also difficult to overcome.... After a gap of up to 17 years, Toyota's number one performance indicator "Bull Devil" Supra finally appeared a fifth-generation successor, which naturally swept the car playing community and became a high-heat modified car!
Thanks to the enhancement kit and modification technology, even if the B58B30 engine equipped with the body is not low in upgrade, the output peak is more than the original factory can be said to be easy to write at present, but the cylinder body is made of aluminum alloy material, plus the gearbox is self-designed, but also makes its power and acceleration modification limit, obviously more than the previous version of the JZA80 with cast iron cylinder body + manual transmission, and also promotes the emergence of the hand-row "old cow" play boom. This JZA80 six-speed manual version, which was developed by Grannas Racing, is equipped with an engine type that is the standard 2JZ-GTE of the original factory, but based on the torque of the German super horse, it is essentially a complete and complete overhaul!
The engine block and cylinder head have been changed to Billlet CNC forged aluminum alloy material, which in addition to the high rigidity performance is better than the original cast iron type, it also has the added value of lightweighting and promoting gravity pushing. In addition, the cylinder body waterway design has also been changed to a fully enclosed style of high-strength victory, and the diameter of the cylinder head airway is also equally increased, with the same forged structure of pistons, connecting rods, crankshafts, bosch bearings, increased valves, strengthened intake assembly, the entire engine body not only the explosive force greatly exceeds the original plant, the crushing limit that can withstand the turbo pressure value also soars upwards!
At the same time, the exhaust capacity has also been expanded from the original 3.0L to 3.4L, so the turbine has a precision Gen2 8891 Turbine with an intake caliber of 88mm and an A/R value of up to 1.08, and the maximum boost value is also set at a super amazing 50 psi, that is, 3.45 bar, which also makes the maximum horsepower soar to 1800whp, and the net output of the converted engine has a spectrum of 2070hp! In order to further improve the horsepower / weight ratio performance, in addition to moderately modifying the body beam frame, the chassis is also moderately changed to a steel pipe structure that can improve the overall rigid performance, with the hood, front fender, and doors are changed to CFRP material, the overall weight is actually a lot lighter, the horsepower / weight ratio performance is greatly increased, and the acceleration response is definitely more sharp!
Because the engine output is more than seven times higher than the original factory, the variable speed responsible for transmitting power is even the H-type hand-row type, which is known for its high endurance limit, but it still cannot withstand the destruction of this 2000hp engine, so it is also upgraded to the same as the original V160 with a 6MT six forward speed manual design, but it is the same as the camp Magna Powertrain, the maximum torque can withstand more than 1000 Nm, and the T56 enhanced version is equipped with an oil pressure type clutch release bearing! Coupled with the reinforced steel drive shaft and the reinforced rear differential, even if the second-shot clutch will not have a "hanging point" dilemma.
Through Grannas Racing's frequent and active participation in the pursuit of the best setting of the whole car, this fierce "hand steak" zero four seconds has long been the world's top level of hand row cars, the best time before this year was 6.849 seconds, 346.6km/h (215.37 mph), but in order to achieve another good result, the TX2K22 acceleration race was recently fine-tuned, zero four seconds in addition to rushing out of the personal high of 6.834 seconds, through the final speed also exceeded 350km / H da mark to 351.21km/h (218.23 mph), which can be compared with the modified GT-R God of War, but also refreshed the global handteped car zero four speed record, itself the color of the sacred cow is also deepened!
