Speed Academy’s Nissan S13 LSx Swap Guide

Speed Academy created a series on swapping a LSx motor into a 240SX. This guide has a lot of good information such as picking a Cadillac CTS-V accessories setup because it’s the most compact and fits the S13 with no clearance issues. The only drawback is the series is more of an overview. The builder doesn’t go into a lot of detail for those who would a prefer a step-by-step guide. I have outlined each series below.
