Why Buy a Used Lexus Engine from Auto Power Source
Lexus builds on Toyota engines, and every product on this page is titled by the Toyota engine code — the 2GR-FE, 2GR-FSE and 2GR-FKS are three different 3.5 V6s that share a badge, the 1UR-FSE and 1UR-FE 4.6 V8s differ in their fuel systems, and the hybrid FXE engines run an Atkinson cycle that makes them useless in a non-hybrid car. Our 541 verified Lexus engines cover the whole run: the 2GR family in the RX350, ES350, IS350, GS350 and RC350, the 2GR-FXE in the RX450h and GS450h, the UR-series 4.6 and 5.7 in the LS460, GX460 and LX570, the UZ-series 4.0, 4.3 and 4.7 in the LS400, LS430, GX470 and LX470, the 5.0 2UR-GSE in the F cars and LC500, the 1MZ and 3MZ in the first RX and ES, the 8AR-FTS turbo four in the NX and IS, and the 2.5 hybrid fours in the ES300h, NX300h and UX250h.
Every Lexus engine we sell has been pulled from a low-mileage donor vehicle, cataloged by VIN, and held in our climate-controlled warehouse pending sale. Each unit goes through our six-step inspection — VIN-matching against the donor and against your vehicle, compression and leak-down testing of every cylinder, noise verification, full visual inspection of block, heads and timing cover, multi-angle photography for your approval, and palletized freight. 2GR units get a VVT-i oil-line and timing-cover review, UR and UZ V8s get a timing-belt or chain inspection, and turbo units get a turbo-shaft check. Rejected units never reach the buyer.
You pay a fraction of dealer-new pricing for the same Lexus engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and have 30 days from delivery to return for any reason — no restocking fees. The warranty printed on the listing — with extended coverage up to 3 years available — covers you if anything goes wrong after install. Across 100K+ engines and transmissions in stock, we hold a 0% fitment-related return rate.

Lexus Engine Buying Guide
5 things to verify before buying a used Lexus engine:
-
Match the Toyota engine code, not the displacement. Every listing on this page carries the engine code — 2GR-FE, 2GR-FSE, 2GR-FKS, 1UR-FSE, 2AR-FXE — and that code is what fits. The 2006 IS350 and the 2007 RX350 are both 3.5 V6s and take different engines; the 2015 RX350 and the 2016 RX350 differ again. Confirm the code from your VIN before you order.
-
Port injection, D-4S and Atkinson hybrids do not interchange. The port-injected 2GR-FE, the D-4S dual-injection 2GR-FSE and 2GR-FKS, and the hybrid 2GR-FXE share a block and nothing that bolts to it — heads, injectors, fuel pump, cams and ECU all differ. The same split runs through the 1UR-FSE against the 1UR-FE and the 2AR-FXE against the 2AR-FE.
-
VVT-i changed the UZ and MZ engines mid-run. The 1UZ-FE 4.0 went VVT-i in 1998 and the 1MZ-FE 3.0 in 1999 — different heads, intake and ECU — and the listings say which build they are. A non-VVT-i LS400 or ES300 engine will not run in the later car, and vice versa.
-
Toyota donors are often valid — when the code matches. The RX350 shares its 2GR-FE with the Highlander and Sienna, the GX460 its 1UR-FE with the Land Cruiser, the LX570 its 3UR-FE with the Tundra and Sequoia, and the ES300h its 2AR-FXE with the Camry Hybrid. Our listings name the donor, and a Toyota-badged unit with the same code and year is the same engine.
-
Confirm the match with your own VIN before you order. Your VIN settles the engine code, drivetrain and build split in one step. Text it to +1-307-441-5554 and we will confirm in writing exactly which unit fits your vehicle before you pay.
Our ASE-certified technicians verify every one of these points against your VIN before any unit ships.
