Direct Replacement: This turbo can be installed on 1999.5-2003 model years as a direct bolt-on replacement. All connections to the vehicle are compatible with the OE geometry, resulting in a quick and reliable connection. Maximum gains are achieved from fuel system upgrades, either electronic or mechanical. 4" Anti-Surge Chamber with High-Temp 5-Ply Silicone Torque Booster Tube: This turbo has an oversized 4" inlet featuring a ported shroud compressor housing, which helps to reduce "turbo bark." A 5-ply reinforced high-temperature silicone torque booster tube is included for a hassle-free installation. Billet Wheel: The compressor features a gold-anodized 6/12" bladed billet aluminum compressor wheel that is lighter and stronger than the stock cast wheel to help provide quicker spool-up and higher airflow than the stock turbo. Compressor: The compressor features a lightweight billet aluminum compressor wheel with a 66 mm inducer and 88 mm exducer to improve turbo spool-up, handle high wheel speeds, and boost pressures. Also included is a CNC-machined black-anodized adjustable billet aluminum wastegate actuator. 1.0 A/R Turbine Housing: The larger 1.0 A/R housing vs. stock 0.84 A/R results in lower EGTs.
