My new 944.
 

I recently bought an 86 944. its the base model, its mechanically sound, but rather underpowered:/ does anyone have some tips on some modifications i could make to improve my performance without stripping the interior for weight?
also i was considering a swap, but dont know if i could make this engine fit.
