Perfect EJ207 for My STI Swap – Flawless Condition!Bought a ver.8 EJ207 from JDM Premium for my 2004 WRX swap. Engine arrived crate-sealed with compression test results (150+ psi all cylinders) and zero leaks. Installed with minimal fuss using their included wiring harness. The AVCS works perfectly, and it pulls like a train to 8,000 RPM! Shipping was faster than expected. Will 100% buy from them again.

Turbo-Ready Beast – Handles Boost Like a Champ!
Needed a strong base for my 500HP build, and this ver.9 EJ207 delivered. Forged internals are untouched, and the heads are mint. Running a GTX3076R at 24 psi with zero issues. JDM Premium even threw in a free engine stand! Only docked a star because my wife says I talk about the car too much now.

Low-Mileage Gem – Runs Like New!
Took a chance on a ‘used’ EJ207, but this engine looks and runs brand new. Only 54,000 km on the clock, and it came with the OEM turbo, ECU, and even the exhaust manifold. Fired up first try in my GC8 Impreza. JDM Premium provided clear import docs and answered all my tech questions pre-purchase. Top-tier service!

Great Value – Minor Cosmetic Quibbles
Engine runs perfectly, but the intake manifold had some surface rust (common for Japan’s climate). Compression was 148-152 psi across all four, and the included VF37 turbo spools fast. JDM Premium offered a partial refund for the rust, which I appreciated. Still a steal for the price!

Saved My Rally Project – Customer Service is A+!
My EJ205 blew up before a race, and JDM Premium overnighted a ver.7 EJ207 with a twin-scroll setup. Their team helped me verify compatibility with my drivetrain, and the engine came with all sensors and coil packs. Finished the rally and podiumed! These guys are lifesavers.
