Year-to-year notes

Small chassis differences can change clearance, wiring effort, and parts choices.

S13

Common planning differences

Verify for your exact trim/year.

Notes

Brake booster and steering clearance, engine bay space, and accessory packaging can vary by setup.

S14

Zenki vs Kouki considerations

Packaging and cooling layout can differ depending on components.

Notes

Cooling ducting, fan clearance, and front-end component variations can impact swap packaging.

Engines

Electronics differences matter

Engine year often changes ECU strategy.

Notes

DBW, immobilizers, and CAN integration change the wiring plan more than mounts do.
