Cams, valvetrain and injectors just installed. Beginning new tune with Vit. I can already notice a huge difference without WOT or high rpm driving. Sounds deeper, meaner. Throttle feels twice as free as before, with just bolt-ons. When the tune is complete this thing will be all motor sick. Get more parts!

Be advised that disassembling the motor and rebuilding the head is 100% no joke. Whoever does it needs to be really good or a number of things could go wrong. Professional installation of internal equipment is a must, or your engine may never run properly again.
For thousands less you could add FI and get more power. I chose to stay NA because I like the concept of refining the K20z3 to the point that its hp/liter ratio is crazy. Ultimately I'd like to install a stroker kit, but that's $$$. Disassembly also allowed me to fully inspect the engine and replace vital parts as needed.

good stuff. Always good to see all motor builds still being the used these days. I agree, find a good mech, no turning back once you crack the motor open, however once its all said and done, well worth the wait.
