After attempting some badge engineering to enter the compact truck market, GM developed the S-10 and S-10 Blazer to grab market share in a growing segment. In order to keep costs down, GM robbed a significant amount of chassis parts from current G-Body vehicles, making shoehorning the late model GM V8 of your choice very straightforward.

Wet nitrous systems are the most popular option since they provide the extra fuel to support the added nitous, and don't require any modifications to the fuel injection system (no custom programming of the computer to add fuel when the nitrous is activated). Dry nitrous systems are generally used in racing applications in combination w/ the HP or Dominator ECU w/ custom calibration to add the extra fuel using the fuel injectors (in an EFI application).
