Suggestions on how to make my new LQ9 last

[MrHorsepowerLSx]

I have a NEW....haha NEW LQ9 coming from GM, i have a few other post on here and i run a decent list of mods, soo i would like some input on how i should go about breaking in this engine before something the bed again like last time. So should i break it in with the turbo on or disconnected, should i cam it right out of the crate, and if soo how should i do it and when should i install the turbo back on if i decide not to install the turbo on it during break in
? any have any problem like this please let me know what you did and what type of combo you were running and what spark plugs would be tter for turbo and non turbo applications..




Thanks

seriously, get a live tune on it once you get it together if you're going to run more than 5 psi. Make sure to monitor the fuel psi while driving. Many suggest you go to a return style fuel system with a boost reference fuel pressure regulator, if you don't have that already.

I have,the return style type fuel rail with a rail mounted factory psi regulator, thay I was told will reference boost

I would do everything right out the gate, put it in the truck and have at it.

A wise builder told me on the first startup take all the sparkplugs out and turn it over until u have oil psi. Then put the plugs back in and start it. But just my .02

When I did my cam swap I was told to unplug the main connector for the coil packs. That let the motor turn over and get everything moving around. After about 30sec of turning it over we plugged the connectors back in and it fired right up like there was never anything done.

Sounds like basicly the same concept except mine doesn't build compression and push down on the dry bearings as hard. Either way is better than just starting it up to me

[Oldspimp]

It's better to disable fuel so you don't wash the cylinders down...

I like the spark plugs out for no compression idea. Wish I had a fresh motor to try it on

I have a fresh hi-perf 5.3 thats almost done for someone to come and start up
