BMW Z4 Car Modification


Louis Tan is a doctor in Singapore and had a hobby of speeding. Although busy with H1N1 cases, he still did not forget his favorite channel on the international circuit Sepang, Malaysia. To the point, the kitchen runway BMW Z4 as mainstay mounts, which was considered as a true roadster classic nan, experienced raise energy.

The reason, 2.5L engine performance felt less competent. To increase the power, the process was aided M54 stroker kit and armed 3.0L supercharger induction system. He said there is no company that supplied directly stroker kit for M54. Therefore, he had to order directly from the United States. The message of which he forged pistons, piston rings, Conrod, and crankshaft.

Polished supercharger kit come Technik Engineering from a snorkel intake, filters, piping, brackets, PULLEY, and belt. To PULLEY, this section has a pressure of 4.5 Psi. To get more power, diamater PULLEY smaller replaced. Aim to supercharger spins faster.

Associated with it, the sewer system up-grade with aftermarket headers, custom re-pipe the middle, and end with ACS Muffler. ECU remapping by the Rhommel from ROM Tuning. This process includes re-setting the ratio of fuel and air, timing, and setting DVANOS (name of the timing control technology in the BMW). If the Honda, the technology is known as VTEC, while the Toyota with VVTi.

Result, the previous standard power under a soaring 200 dk 303 dk. The sound changed a bit more rough, even resembles the F-Engine. Lap top performance and high torque is more kicking now.

Since energy is large, then it must be balanced by the rate freeze system. Kabriolet sedan is equipped with Stoptech 4 piston rotor model 2-piece Slotted 332 mm. "It's best suited for track use," called Louis, who previously had been comparing the device with 4 piston Brembo.

When maneuvering around the corner, because of fierce energy, cars need stability and a minimal level of rocking. For legs sector there are two choices, Bilstein PSS 9 and KW Variant 2. Based on various inputs from friends, Bilstein has a character more gentle swing. Meanwhile, KW Variant 2 by Louis more fitting for the character of circuits that require hard suspension.
