yes, there is one combo that works time and time again for GTRs running small-ish low mount turbos.
Nismo fuel pump with Sard 700cc injectors. the nismo pump flows 276 litres per hour which is enough to support 6 X 760 cc injectors, so it's a good match for the sard 700s.
plus it fits straight in and has proven to be reliable. the money you save with cheap pumps is easily wasted in time taken to fit them and potential reliability issues.
don't forget to buy new injector 0-rings from nissan for the injectors.
