Wesley,
I am building a very similar build. I have literally spent 6 months reading this and other websites trying to get answers that you pretty much hit in a single post.
N42 Block
N42 Head
N42/P82 Intake manifold since they're both non-egr. I am leaning towards a n42 but I am having issues finding one.
MSA Stage II cam kit
MSA 6-1 Header (Jet Hot)
MSA exhaust system
All ARP Hardware
Dished pistons (I may want to run a turbo one day)
Everything either ceramic coated or nitride treated, glyptal painted inside the bottom of the block
Megasquirt III
Single wideband oxygen sensor
8' wiring leads made into a custom harness (make this myself)
Coil packs for each spark plug. MS version, the are similar to the Truck packs
120amp Alternator
I would really like to know if I can just buy the CAS turbo dizzy (83 turbo) and run the DIYautotune Trigger wheel versus buying the crank trigger
