5x18 would be your next step assuming we are talking about a 12v

5x16 would be the next step, 140's are 5x14's. Depends on what you are doing. Nozzle design is just as important as hole size/count.

Who makes a good 5 x 16 or 18 then ? Using truck for a little daily driving but mostly hooking it to the sled since I replaced the head.

SDX has a good name. You could also talk to Exergy about custom nozzles. There are lots of smaller guys doing injectors now. Several of them are sponsors on CompD, pick one you interested in and call them.

correct...my bad

I went with 7x10's instead of 5x14 I got them from contagious and I am really happy with them. A nice increase over my 5x12's and man do they run clean!

Thanks for the info guys. In the process of putting either a modded 6.0 vgt or modded he351ve on my truck I just don't want to go overboard on fuel... Just a step up on the 140s.

Guys have done 700+ hp on 5x14 injectors, so not sure why you're gonna upgrade those when you are looking at running a 500hp turbo when maxed.
