The Good Stuff 2018- Symposium on Best 911 Engine Components

It's been a while since I asked this question so I thought I would throw it to the group.

What are the latest, best approaches to 911 engine components?

I'll take a stab at it:

Cylinder Heads-- Xtreme D-port heads, CNC machined

Crank-- Custom cranks from Pauter, Marine Crankshaft utilizing NASCAR bearings

Case- new manufacture 964 cases not yet GA-- so same old heavy machine work-- align bore, oil bypass, squirters, spigots, oil pump clearance, media tumble.

Oil Pump-- GT3

Cylinders-- LN

Pistons-- ?? Which are regarded as state of the art today?

Rods-- Carillo, Pankl, Pauter

Induction-- ITBs- PMO EFI

Engine Management-- MoTec, AEM

Ignition-- Bosch COP driven by engine management system

Crank triggers-- ??

Engine Tin- Fiberglass RSR

Exhaust- ??

Trying to put together a list of the "DREAM" components-- if you were building an aircooled 911 motor, and cost were not a consideration, what would that look like.

Your input welcome

Crank triggers = 996 606 105 00 (Bosch)

Engine Management = Completely biased, but having spoken at length to those who know (and have used many of the usual suspects), and now work for them, I'd say Life Racing (for racing applications) aka Syvecs (as the more roadgoing variant, but same HW and coded by the same folk at Life Racing)

Ignition - Ford Ecoboost - being used more and more on this side of the pond, massive bang (literally) for your buck

Injectors - Injector Dynamics (both profiled/matched sets of Bosch Motorsport injectors, or for their newer range, ID design made by Bosch MSports for Inj Dyn)

Pistons - CP Carillo, Capricorn, Omega

The Pauter rocker arms look nice but have no experience with them.
As for ITB's the ones from AT Power supposedly make good power with their shaftless design.
