up my 2732 cpl to a higher tier - thinking 2919 right now, but will get some input before I order pistons and injectors
...

that would require different...

* Pistons - (different compression ratio, lower crown in center of higher hp pistons)

* Injectors - (bigger chamber size to allow for faster fuel flow at the higher volumes into the cylinders )

* Injector cam - (completely different injector starting angle to accomodate the different injector profiles)


* Entire head is different- (bigger exhaust valves in the head)

* Valve cam - (matches up with the bigger exhaust valves in the head)


* VGT Turbo is also different - (Heavy-duty titanium, high heat turbine and higher flow housing)

====

Valve cam is the same - injector cam is different. Head shows the same # as well, but I'd be tempted to just go with a new head anyway. Other than 9k for new, not reman injectors, the turbo may sting a little if it's not something I could sort out with Yiyito. There's no valid need to justify any of it, just my want. No idea how much time I have left on this rock, or in a truck for that matter, so it's something I want to do while I'm able.

Here is what quickserv currently shows ...

NOTE: Not installing the exact kit for your engine CPL and ser# voids all warranties. it also makes for the need of custom programming to correct for any hardware changes so that the engine will run 100% efficiently.
