This isn’t a conversion kit or an adapter plate hack. ESCORT did the full R\u0026amp;D to make this transmission bolt directly into your S30Z or Hakosuka (C10 Skyline) with zero chassis modification required.\u003c\/p\u003e\u003cp\u003eThe engineering behind this conversion is serious work. ESCORT sand-cast a custom bellhousing, then precision-machined both the Nismo and cast housings to a pressed fit. After TIG welding them together, the bellhousing was shot-peened before final reassembly — a process that improves fatigue strength and surface integrity. The result is a 6-speed transmission that bolts cleanly to your L-Series engine.\u003c\/p\u003e\u003cp\u003eAdditional machining operations were completed on the case and shifter housing to ensure the shifter position works with the factory S30 or Hakosuka trans tunnel. \u003cstrong\u003eNo tunnel modification required.\u003c\/strong\u003e The kit is complete with a billet aluminum crossmember — this is a true bolt-in affair.\u003c\/p\u003e\u003ch3\u003eTransmission Specifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBased on the Nissan S15 Nismo close-ratio 6-speed\u003c\/li\u003e\n\u003cli\u003eStrengthened from the factory S15 unit — rated to support \u003cstrong\u003e345 bhp\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eClose-ratio 1st through 5th gears for canyon carving and track performance\u003c\/li\u003e\n\u003cli\u003e6th gear: \u003cstrong\u003e0.8624 overdrive\u003c\/strong\u003e — perfect for highway cruising\u003c\/li\u003e\n\u003cli\u003e5th gear: \u003cstrong\u003e1:1 ratio\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eRetains \u003cstrong\u003emechanical speedometer drive\u003c\/strong\u003e — unlike the standard S15 trans, so factory gauges work without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eConversion Engineering\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSand-cast custom bellhousing machined to pressed fit with Nismo trans case\u003c\/li\u003e\n\u003cli\u003eTIG welded bellhousing-to-case joint\u003c\/li\u003e\n\u003cli\u003eShot-peened bellhousing for improved fatigue strength\u003c\/li\u003e\n\u003cli\u003eMachined case and shifter housing for correct shifter position — no trans tunnel modification needed\u003c\/li\u003e\n\u003cli\u003eIncludes billet aluminum crossmember\u003c\/li\u003e\n\u003cli\u003eBolts directly to L-Series engine\u003c\/li\u003e\n\u003cli\u003eCompatible with S30Z (240Z, 260Z, 280Z) and Hakosuka (C10 Skyline)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhy This Transmission?\u003c\/h3\u003e\u003cp\u003eA single overdrive gear for relaxed highway cruising.
