Crunch the numbers man its still $60 cheaper?!
There isnt gunna be any additional costs in installation with the top feed injectors & rail as the rail comes out to install the injectors anyways..Xspurts are gunna drive SOOO much better throttle response will be better spray pattern will be much better which will probably aid in fuel economy and save you $$$ down the line anyways. Honestly old tech injectors like the densos are MILES behind EV14's & sure you wont see it on a dyno sheet BUT you will notice the difference driving it and putting around on light throttle etc..
