What's next? that seams the to be the Question. I have an Early 04 Cummins HO, 305/555 motor. NV5600 6 speed, 4.10 gears, Hell bent leveling kit, 315/70 r17 Duratracs, Regular cab. mods that I have now. AFE mega Cannon, MBRP 4" stainless Exhaust, Smarty pod TNT-R, Valair 3600 Duel Disc clutch, Gauges, EGT, Boost, Fuel, SR Mia, have Air dog 165 just not on truck yet, soon. so what should I do next? I Drive this truck on Weekends and on trips looking for 500 to 600hp at rear tires, Going to some shows this summer so going to be looking for Parts. Was thinking Head studs, And while there getting Valve Springs, then while apart thinking of doing injectors, but Don't have the cash for all three. or should I get a bag of parts for CP3 and go for a turbo. Just can not decide. Any suggestions on what to do and why Will help. Truck has 73000 Miles on it. Thanks in advance

 

If it has 305 hp it is the LO and you honestly can't do one or two of the three you almost have to do all three at once I would buy 60hp nozzles and a remaned 33 % over cp3 from industrial injection and either a 62 or 64 mm sliver bullet from them also and arp mid strength head studs for safety if you decide on a 62mm turbo than they won't be that nesscery as far as valves aren't gonna be needed at all at this level

 

If you have over 150k miles I would skip nozzles and get full injectors. The internals are likely worn on them by that point and you will save time by not replacing them again. + if you tear into new injectors to swap your performance nozzles on to them then you void the warranty and can have problems with larger variance on the new injectors.
