I have a few drives for my condas that each yeild a range of 62ly or higher for my exploration build (which includes shields, SRVs, and SLFs). While the FSD mod is certainly important, it has been my experience that the second most important mod (in terms of impacting junp range) has been the lightweight mod on the internal sensors.
The next important item is the power plant and thrusters. Get a too small power plant that is overcharged enough to handle just under your max power requirements. You can disable yor cargo scoop, planetary hanger, and AFMU until you actually need them. I believe the clean drive mod can reduce mass as well, but not sure off the top of my head. This will also allow you to get a smaller capacitor than you had before, though you may not be able to boost in this configuration.
It gets harder if you add shields, but not impossible.
