Pontiac Grand Prix
GT and supercharged GTP cars made the W2 Grand Prix one of the platform’s defining performance models.

1997–2005 ERA · PERFORMANCE-FOCUSED
W2 / Second Generation W-Body
Master Customs concentrates this chapter on the W2 cars that matter most to enthusiasts: the supercharged 3800 sedans and coupes, the Intrigue’s unique DOHC V6, and Chevrolet’s performance-oriented Impala and Monte Carlo variants.
Editorial focus: W2 was a broad family, but Master Customs is not trying to catalog every fleet or commuter variant. Buick Century is intentionally omitted as a stand-alone model guide. It will appear only where its shared W-body parts or technical context matter.
ENTHUSIAST MODEL INDEX
The W2 cars worth going deep on.
These five nameplates carry the strongest performance, engineering or modification relevance in this era.
Buick Regal
The sleeper choice: L36-powered LS and 240-hp supercharged GS, with understated styling and strong 3800 aftermarket support.
Open guide →Oldsmobile Intrigue
A different branch of W2 performance—first the Series II 3800, then the 215-hp DOHC 3.5L LX5 and chassis/electronics features aimed at import sedans.
Open guide →Chevrolet Impala
LS 3800 cars built the base; the 2004–2005 supercharged SS turned the sedan into a genuine factory performance W-body.
Open guide →Chevrolet Monte Carlo
SS coupes started with the naturally aspirated 3800 and culminated in the 240-hp Supercharged SS for 2004–2005.

CHRONOLOGY
W2 runs into the W3 overlap.
The 2004 Grand Prix begins the next Master Customs W3 chapter while the W2 Regal, Impala and Monte Carlo continue alongside it. Pages follow each nameplate’s actual body generation instead of forcing every car into the same cutoff year.
REFERENCE STANDARD
Master Customs prioritizes factory-era documentation and period road tests, then uses established enthusiast references for service and ownership context. Equipment changed by model year and RPO; verify a specific car by VIN/RPO and factory service information before ordering parts.
