I personally wouldn't have a problem with that....
First I'd find out what HPFP and injectors are currently on the car. It would take a mechanic less than a half hour to check.
The latest injectors end in 261 and if I remember right the latest HPFP ends in 194.
There are very few problems reported with them now although the injectors seem a bit more susceptible to things such as leaking and misfires. $125 a piece and a coding set up (all easy with good documented DIYs) and 30 minutes and you're good to go.
Anyway, after that if everything checks out...I'd beat em upon price and enjoy!
