91 - 02 Saturn Parts Swap Guide

This video is a basic explanation of the changes Saturn made to the S series engine and transmission and how it affects swapping parts between different years of car. I forgot to mention in the video about the ECU and harness, so here it is: 91-95 SOHC: TBI 1 injector, 2 temp sensors, 2 plug ignition module 91-95 DOHC: MPFI 4 injectors, 2 temp sensors, 2 plug ignition module 95-99 SOHC/DOHC: MPFI 4 injectors, 1 temp sensor, electronic EGR, single plug ignition module 99-02 SOHC/DOHC: MPFI 4 injectors, 1 temp sensor, electronic EGR, single plug ignition module, secondary AIR system. 99 - 02 Used LS style knock sensor 91 and 92 crankshafts have a different reluctor ring and will retard timing if used with a 93 - 02 ECU 91 DOHC cylinder head is weird and should be avoided Link to differentracing.com: https://web.archive.org/web/202401212...
