I have heads, all I need is the balancer now! I misread the add it came with heads I haven't even opened the box yet. But one last question this is what I have
-heads
-sc and lower intake
-fuel rails and injectors
-coil packs
-valve covers
-balancer (needed)
-3.8 pulley (need serpentine belt)
-I have full 3" exhaust with a magnaflow cat'd down pipe
-looking for headers
Other than all this and a good tune. What else do I NEED, and what else should I probably consider getting?
Future mods
- headers (unless I get them before the top swap)
- inter cooler and heat exchanger (zzp)
-er ratio rocker arms
- maybe bigger injectors

 

you will need some wiring harnesses to connect all the wiring, i think zzp sells the harnesses (not familiar with what it is you need but i read about it a long time ago)

 

Something to scan your motor for KR.

 

I have the harmonic balancer and the plugs for the injectors. Say $30+shipping?

 

You will need a new coil pack bracket off an l67, and the additional idler pulley and bracket.

The extensions for it
The Injector pigtails as stated before
The BBV on the supercharger if it doesn't come with it.
