Art style: манга 4.
Tampilan sangat dekat mesin RB20DET yang kotor di dalam ruang mesin mobil tua. Permukaan logam tertutup lapisan oli hitam tebal dan karat kemerahan pada blok mesin. Kabel-kabel tua yang getas melilit di sekitarnya. Pencahayaan lampu neon bengkel yang redup menciptakan bayangan tajam dan suasana melankolis industrial.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "манга 4" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "манга 4".
Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "манга 4" idiom, not in any other medium.
