[QUOTE="Wayne, post: 266416, member: 863"] Elite injector nozzles come with injection lines. Tow powers come with install gasket kit. A new injection pump cover gasket comes with the lines from the pump to the rails. Ford recommends replacing the gasket any time it is removed. The wires in the cover gasket are prone to failure, especially on gaskets with lots of miles. Wire failure = engine not starting, and turbos back off to change the gasket. Unless you do custom tuning to decrease PW, you will see a significant increase in egt's constantly with that turbo upgrade. Even then, you might see higher than acceptable EGT's. You'll never be able to use those injectors to their maximum capability without a whole lot more air. Those 60% over nozzles are serious overkill for what you have. 60 HP, not 60% are recommended for the tow-power combo. 60%, or 110 hp nozzles are ideal for max-power turbos (way larger). Although those are recommended figures, more power capability is possible with oversize injectors, it is a trade-off of higher egt's and excessive smoke. Good? sure they're good, but are they better than the billet precision wheels that are already included with the turbos to begin with? All precision vs. batmowheel testing we've done suggests you'll lose power by going with the batmowheel over the precision. Custom tuning will be crucial with big injector nozzles and stock pump. The DIY bag of parts, as mentioned before, is not available yet. As for any advice from me, in a daily driver you may tow with, I'd prioritize air flow over increased fuel capability to get power with good EGT's. I'll be doing the ported intake, double billet tow power turbos, (no limit IC pipe and elbow already done) 4" down pipe, and when it's available, the bag of parts injection pump upgrade. Also plan on ported rails, airdog II and fuel bowl delete all with stock injector nozzles and custom tuning. For years, duramax guys have been running 3.2+ ms pulse width, and the most I know of 6.4 guys running is 2.25. My theory is unproven to my knowledge, but if it isn't done before I get to it, I'd like to see just how much can be done with stock nozzles to keep minimal smoke and EGT's at sub 600 hp levels, and have solid power when I do sled pulling or screwing around. If increasing the pulse width doesn't work out well, then I'll go back to dropping 60 HP nozzles in. Food for thought at any rate. [/QUOTE]
