hey guys, its time for me to adjust my valves and when im in the process i want to put arp studs and nozzles in my truck. I plan on running it with the he 351 for a little while and know i need more air, but do not want to buy small nozzles then after i get more air have to go to a larger size. So what nozzles should i go with. i like the price on wicked diesels 180hp mafia nozzles but dont think i have an adequate setup to run them. I plan on building my truck to around the 600hp range. any suggestions appreciated

 

Anyone

 

You can get 600 hp with 50hp nozzles on a common rail.

 

180's are definitely overkill for 600hp. With your '03 90hp nozzles, BD SuperB Special, Arson III will put you at 600hp.....maybe a little more. You could run 120's with the Special, but it may get a little hot.

EDIT. Just saw that you have an '03, the 120's may suit you better
