Will these work with a 98 LD9 S/C (stock pulley) and a walbro pump and cartech fmu?
Are they just plug and play or is there cutting and splicing?
If they both work... Which do you recommened?
I'm running SS/SC injectors on my 01 Z24. It required some mods to the fuel rail (because they are shorter than stock). For your 98 the HO injectors should be a direct swap. The SS/SC would require different injector harness as well.
