hmm, sounds like a v-6 northstar. i see it has an aluminum intake. do new northstars have plastic intakes? i thought the rendevous? had the 3.4L motor? and the CTS base has the 3.2L 220hp. sounds like 3 different motors.

The Catera had a 3L opel based engine. That engine got "completely redesigned" to a 3.2L engine for the CTS in 03. That 3.2L engine continues in the CTS in 04, but is only available with the 5-speed manual.

The new, more powerful "high-value" 255 hp 3.6L V6 with variable valve timing is available only with the 5-speed automatic transmission for the CTS. The 3.6L is also available in the SRX at 260 hp, and detuned from to 245 hp in the Buick Rendezvous. This is a new engine, and is referred to internally at GM as a High Value V6, with the best features available in any comparable V6 engine.

ALL-NEW ENGINE FOR 2004 BUICK RENDEZVOUS, CADILLAC CTS AND CADILLAC SRX

The 3.6L V-6 VVT(RPO LY7) is the standard engine in the CTS and SRX and an option in the Rendezvous Ultra. This 60-degree DOHC V-6 was developed jointly for global application, drawing on the best practices and creative expertise of GM technical centers in Australia, Germany, North America, and Sweden, and based on the philosophy that a true family of global engines provides the best value and performance for the customer and the best return on investment for General Motors. The 3.6L V-6 VVT applies the most advanced automotive engine technology available, from state-of-the-art casting processes to full four-cam phasing to ultra-fast data processing and torque-based engine management. It delivers a market-leading balance of good specific output, high torque over a broad rpm band, fuel economy, low emissions and first-rate noise, vibration and harshness control, with exclusive durability enhancing features and very low maintenance.

The 3.2L V-6 that powers the manual-transmission version CTS was completely re-engineered for the 2003 model year. The engine makes 220 hp (164 kw) at 6000 rpm and 220 lb.-ft. of torque (298 Nm) at 3400 rpm. The engine was fully revamped to improve driveability, power, torque and emissions and designed to take full advantage of every bit of its 220 horsepower.
