Ville Vizi and are particularly good at the collar Yin, pressurization and NA are also led by Yin proficient. After Ville TURBO for small blessing, but also for the Yaris small chopper pilot, was to change NA, NA this change, it's not easy to replace the intake and exhaust, but also uniquely local. Yin collar NA changed a few cars in the TCCR achieved very good results, some players think the speed is too fast, there is the expansion tank is suspect. Neck Yin agreed to provide technicians dismantle the engine for testing. But in the end it was agreed that no expansion tank, also stopped the controversy.     Yin collar car really is no expansion tank, this field through our verification. Such a dispute, in fact, with the rules of international and domestic competitions and events not related to standards Hyundai Terracan 163HP Turbo. In the international management, as long as the blessing of the turbine car, all attributed to unlimited modification group, rather than domestic multiplied by a factor similar. Another rule is not the same, but also related to this dispute, the international management, the most junior A group of modification, is not able to relate to the camshaft and cylinder attendance, which is allowed in the country. Theravada cylinder grinding, if coupled with the replacement of the high angle of the camshaft, to enhance performance, can be said to be a revolutionary, it will definitely surprise people.     First contact with the modified car enthusiasts, and even some already converted more familiar lovers will think NA change just pediatrics, TURBO is the ultimate weapon that NA is better to change TURBO change Terracan 2.9 CRDi Turbo. In fact, this view is wrong. NA change and change just two different supercharged modified orientation, which is better and not what widowed. An excellent NA engine, power is absolutely stunning, Honda B18C, K20A this generation NA crew, no way inferior to the same generation of machines TURBO name.     NA primary change, mostly just replace the whole paragraph style and high-flow exhaust. By mid-level, attendance is on the cylinder sanding and finishing, higher order, is related to the camshaft and cylinder specific work, such as valve timing and lift adjustment in these areas. You know, the same as I-VTEC, the Honda engine and general engine red head, which in addition the same name, is almost essentially different in nature. Yaris car modification, except that the intake mushroom head and Lei Li banana, KGS straight out of the middle and the end of exclusion, a very important place on the cylinder 28201-4X710 Turbo is a lot of refinement and adjustment. Increase the diameter of the throttle, providing more adequate amount of intake air, cylinder attendance to be polished, so that the intake is more smooth. And do not underestimate the polishing work, in the case of engine speed, will form the inner wall of rough turbulence, affecting the air intake system, reducing the effectiveness of the system.
