_______

The 27WON W1 is the definitive drop-in performance turbocharger for the L15-powered Civic — designed from scratch in CAD, built from 100% new components, and engineered to fit exactly like the OEM unit. No core charge, no fabrication, no compatibility issues with existing bolt-ons.

The W1 features a 59% larger compressor wheel (CNC machined forged aluminum with extended tip technology) and a 61% larger 9-blade turbine wheel for increased flow and power all the way to redline. A larger CHRA with bigger bearings handles the increased stress of high boost reliably. Available in journal bearing or ceramic ball bearing (BB) configurations — the BB version is recommended for high-boost applications and track use.

Power gains (journal bearing, pump gas): +18 whp un-tuned | +42 whp with W1-optimized tune
Power gains (E85): +52 whp un-tuned | +65 whp / +18 wtq with optimized tune

Max operating boost: 27 psi. 5W-30 engine oil recommended post-install.
