Brian Crower Engine Parts

What are the best Brian Crower parts for a Subaru engine build? For the 2002–2014 WRX and 2004–2019 STI, Brian Crower is best known for performance camshafts — Stage 1, Stage 2, and bigger — plus valve springs, titanium and steel retainers, valves, and adjustable cam gears. Cams are one of the highest-impact EJ upgrades: they decide how much air the head moves. If your build has outgrown the stock camshafts, Brian Crower is a proven place to start.

Brian Crower built its reputation on camshafts for four-cylinder performance engines. In this collection you'll find Stage 2 camshafts for the GD and GR chassis, spring-and-retainer kits for the EJ205/EJ257 in titanium or steel, intake valves, and adjustable cam gears with ARP hardware for the Nissan SR20. A bigger cam needs springs and retainers rated for its lift — that pairing matters more than any single part.

What to look for: cam stage matched to your turbo and power goals, spring and retainer kits rated for your cam's lift, and adjustable cam gears if you want to dial in cam timing. Popular pairings include the Brian Crower [08-21 STI] Stage 2 Camshafts and the Brian Crower Spring + Titanium Retainers for the WRX/STI EJ205/EJ257. Comparable engine-internals lines include GSC Power Division, Wiseco, and JE Pistons.

Frequently Asked Questions

Do I need a tune with Brian Crower cams?

Yes — camshafts change how the engine breathes, so the ECU has to be retuned to match. This is not a bolt-on for a stock tune — schedule your tuner with the install.

Titanium or steel retainers — which should I pick?

Titanium retainers cut valvetrain weight for high-RPM builds; steel retainers are tougher for high-mileage street cars. Match the retainer to your spring kit and how you drive.

Are Brian Crower cams street-friendly?

Milder stages keep stock-like manners and idle; aggressive stages trade low-end driveability for top-end power. Be honest about how the car gets driven before picking a stage.

Will these fit my WRX or STI?

Fitment is year- and engine-specific: confirm your year range and engine code (EJ205/EJ257) against the product's fitment info before ordering.
