list all the aftermarket parts you would put on an 04 cummins. im doin this for a friend to give him some ideas. he wants a good amount of horse power. would smarty be the right choice or a quadzilla?

 

Smarty is good TST even better. Turbos aren't the best on the 555 engine so I would recomend a upgrade there.

 

Isspro EV2 Gauges (Boost, Pyro, Rail Pressure)
5" Exhaust
Intake Kit
Airdog or Fass Fuel System
Smarty
Transmission Upgrades
Turbo
Aftermarket CP3
Injectors
Head Studs


That should get him started.

 

cold air intake
intake elbow
chip of some kind (smarty, egde, etc)
exhaust 5"+ (turbo back)
injectors
fass/ari dog fuel system
gauge pod (egt, boost, trans temp)
turbo upgrade (compound, or bigger)
head studs
exhaust manifold

 

GET a FAss fuel pump with some nozzels and a smarty. that should get your friend around 400-450hp mark

 

thanks guys. great lists!
