Description

The V8 Roadsters MX5 NA/NB LSx Mounting Kit is engineered to facilitate the installation of GM LSx engines into your Miata chassis. This kit is built upon V8Roadsters' extensive experience since 2007, offering a refined solution for mounting the 3rd or 4th generation LSx platform. It is compatible with both manual and automatic transmissions, including the F-Body T56 and 4L60e. The kit features a CAD-designed, lightweight tubular subframe that maintains all original suspension pickup points and steering geometry. The engine placement is optimized to preserve the Miata's characteristic balance. CNC-formed frame rails are incorporated to enhance torsional strength and serve as transmission mounting support. Included in the kit are lightweight engine plates with Energy Suspension polyurethane mounts, a transmission cross member with provisions for exhaust routing, and DOM tubing construction for the cross member. It also comes with laser-cut and CNC-profiled frame rails for uni-body bracing and all necessary Grade 8 hardware. The components are finished with a dark gray gloss powder coat. This kit requires the use of either an aluminum screw-on filter oil pan or a remote steel pan for track use. This mounting kit is available for both NA (1990-1997) and NB (1999-2005) generations, and supports both Left-Hand Drive (LHD) and Right-Hand Drive (RHD) steering racks. New transmission options include the Tremec T56, TKX, and Magnum F models (TUET16363 wide ratio and TUEt16362 close ratio).
