i have 01 24v with 200hp injector, 0.093 tubes, cold air intake, intercooler, intake manifold(horn), snow performance water meth, dual disk south bend clutch, i have a stock turbo but looking to upgrade to the 62mm silver, and the injection pump is stock but also want to upgrade. Im trying to figure out whats up with the nv5600, im reading on other forums that there garbage... my trannys got round 200,000 on it. Is there an upgrade rebuild kit for it? Or is the FSO6406 a good replacement? But with out spending a crap load, which i want to put into the engine.
