Okay, that helps.

No harm in starting with a cam if that's how you want to roll. But since you'll need valve springs and pushrods and this is a fifteen-year-old engine, consider pulling the heads for a valve job and porting. Have the valve seats upgraded at the same time, you don't want to spend a small fortune on your 5.7 only to have it blown up by a dropped valve seat.

That would be the time to do headers or SRT exhaust manifolds as well.

You can also step up to an 09-up Eagle, 6.1 or 6.4 intake manifold, but that's not plug-and-play on your engine. You'd need rails, injectors, and adapters too, unless you have the heads ported to match the manifold. Hopefully on your '06, your EGR is on the passenger side head, so that shouldn't be an issue.

You'll definitely want a custom tune to go with that i3.

Even if you do all the labor yourself, this is a lot of money we're talking about...a machine shop won't even sneeze on your heads for less than a hundred bucks...so popping in a cam is a good starting place.

Wow thanks for the great info and taking the time to write that out for me. I am looking for a custom tune as we speak. Can the cam work be done with the engine in the vehicle?
