Lexus RX300 1999–2003 JDM Engines & Transmissions

JDM Lexus RX300 1999–2003 engines and transmissions in Los Angeles

Looking for a replacement 1MZ for a Lexus RX300 1999–2003? This page lists every Japanese-market 1MZ engine and transmission in our Vernon, CA warehouse tagged to fit the 1999–2003 RX300. These are low-mileage imports pulled from vehicles in Japan, graded at auction, compression-tested when they land and photographed on our floor — the unit count updates live as containers arrive and units sell.

Like-for-like replacement engines carry our 90-day warranty and transmissions 30 days, starting the day the unit arrives. Pick up at our Vernon warehouse in LA County, use our local delivery zones across Southern California, or have it crated and shipped by freight anywhere in the mainland US.

Not sure which 1MZ matches your RX300’s trim, transmission or emissions setup? Text or call (442) 888-0318 with your VIN and we will confirm fitment before you order, or use the fitment finder to check another vehicle. Full terms are on our warranty page.
