I use Lucas #42's in every car I build that requires that flowrate , and I have tuned pretty much every injector out there and I have never had any issues with the svo green top or the lucas 42's . Another thing to think about is that price you are seeing is for a set of 4 , so you will need to multiply that by 2 being over $500 for a set , why not just use the Lucas #42's we sell for $289 ? However , the second set you are looking at that is cheaper is Rochester Delphi injector which I have flowtested many times and I personally think is completely the worst style injector out there , that style injector is the one I see fail the most , and also the biggest difference in flowrate of any injector , I could tell you many stories abut these but I can't type forever , lol .
