The raw sounds of loading our 1970 Porsche 911 RSR build into the trailer to get it upholstered. This project is nearing the end, so make sure to follow us to stay updated with our final steps!

The FD Mazda RX-7 is an absolute masterclass in 90s design, but this specific build trades the 13B rotary for the raw power of an LS V8 swap. While the purists might lose their minds, the performance gains are undeniable.

The aluminum LS block maintains the FDโ€™s legendary 50/50 weight distribution while delivering instant, linear torque and bulletproof reliability. Weighing in at roughly 2,800 lbs, this chassis paired with V8 displacement creates a power-to-weight ratio that rivals modern supercars. Itโ€™s the perfect fusion of Japanese aesthetics and American muscle. ๐Ÿ‡ฏ๐Ÿ‡ต๐Ÿ‡บ๐Ÿ‡ธ
