build the trans, use a programmer with intake, exhaust from heads and turbo back. use electric cooling fans. if you're ballsy, you can use electric water pump too. That should get you real close. do head studs
Aftermarket turbo, larger injectors, + the normal exhaust/intake/liftpump/etc. Use EFILive with a good race tune from a reputable tuner.
No handheld programmer will get you close, neither will stock turbo/injectors.
Save your money for the rebuild when (not "if") you bend the rods.
If you are talking just wanting to make rear wheel power on the dyno... it's going to cost. What is your budget limit? You CAN get over 400rwhp for not a lot of money, your transmission will be on borrowed time though.
efi, built trans, modified cp3, lift pump, exhaust, intake will get you really close if not over. my truck (with shitty efi tuning) put down 580. another truck set up exactly like mine, but with atp tuning put down 608 on STOCK turbo and injectors.
that is good to know,i figured that you did not have to change the turbo or the injrctors,the truck already has all the basics,lift pump,exhaust,race valves and ports ect.my next step is the trans,then i think i will go with a egr delete kit,manifolds and up pipes,and a larger innercooler and plumbing before the efi live.efi live seems to be the way to go,many people have suggested it to me.looking to build some hp and be as safe with it as possible!
reliable: built bottom end, stock heads, dual cp3, upgraded injectors, twin turbo, built trans, EFI live tuned by idaho rob, duramax tuner, ect.
u can definitely do it on a stock bottom end, but like others have already said. it won't last for ever.
