you will need a fuel rail adapter since those are the newer style injectors.

^ i believe 90-94 TT and 90-93 NA injectors were all the same so it should be fine with new o rings.

If you're swapping injectors within those years you're good, if you go NA94+ or TT95+ then you need newer style lower plenum or adapter kit. if you are doing a TT swap then yes you need a TT or Walbro Fuel Pump.
