I believe I need to re build my 4.4 N63

[Movado750]

So I pulled the trigger and ordered remanufactured engine.

Like I stated before if I was going to do I wanted to do it.

Redneck is giving good advice and tunes, and injectors.

My build is going to be a small one. my plan is

JB4 tune
index 12 injectors
Meth injections
colder plugs
maybe a custom intake or the performance intake https://www.armmotorsports.com/colle...50i-n63-intake
Anyone used this, I've seen some custom ones done.
The catch can set- up here on the forum.

I've been reading about inter coolers and such but I also read that the stock ones are very good. Do they need to be flushed out or rebuilt?

And if anyone has suggestions loved to hear them as long as it will be full engine replacement. Giddy up!!!

I have the Dinan Stage II installed now, I'm a bit confused and Dinan said it was married to my comp. Will I need to get a whole new ECU?

Nope your good, reuse the ECU. You will need to reset all of your engine adaptations using ISTA however when you install the new engine.
