if you can...try and get an OBD-1 hydro swap, it'll bolt straight in, and be cheaper in the long run. If you've already bought your 1st gen swap, the wiring will be slightly different, as will the transmission will be cable. It will still bolt straight in physically however. The injectors are still saturated type I believe, I don't think they changed to peak and hold untill OBD-2, but could be wrong.
