I'll modify your list with questions as well as my personal idea's. Alot of my ideas came from Mario a few years ago. I've gotten some advice on my Skyline as well as other silly projects I think of.
Nissan KA24DET: 2.6 litre, Double overhead cam, Electronic fuel injection, Turbo.
(question) by your math, does the below bore/stroke equate to a 2.6 liter?
Bore x Stroke: 91mm x 76.7mm (same)
Redline: 8,000RPM (same, or close)
Boost: 50PSI (same, or close)
Electronics: MoTeC ECU and complete logging sensor array with EGT (x1), IAT (x1), Knock (x1), MAP (x1), wide band O2 (x1), launch, traction and air shifter control MoTeC CDI/8 channel ignition spark amplifier. MoTeC Advanced Dash/Logger system.custom 990cc injectors with alcohol injection for high boost.4.0 bar high pressure fuel regulator.Custom oversized and multi tapped fuel rail.
I'll be using a standalone system, up in the air, with the Edelbrock QwikData datalogging system. I already have a standalone alochol injection kit. I might suggest using 4 egt's. That way you get to see each cylinder. One is just a safety thing in my mind. Never to be used a tuning device. The rest is up in the air. Injectors will be chosen while tuning. The fuel rail will be a custom job.
Bottom end: Custom 91mm AB-134 (Aluminium-Beryllium hyper-alloy) forged pistons (x4)( I was actually looking at titanium for the rods and pistons) Berylium is way expensive.
Custom ceramic coated tungsten-carbide main crankshaft bearings. (same, or close) Custom oil cooling system. (same, or close)
Custom titanium connecting rods (x4) (same, see above)
counter balanced crankshaft micro polished pick of 5 different crankshafts that were all xrayed. (a full balance job, spun up to 9000)
strengthened connecting rod boltsstrengthened main crankshaft bolts( all forged studs and bolts)
high capacity oil pump. (same, or close)
lightened alloy pulley set. (same, or close)
enlarged radiator.( same, or close)
Custom head channel modification and complete proprietary GT cooling system upgrade. (complete custom head work)
metal head gasket (of course)upgraded water pump. (electric)
Custom porting and polishing of cylinder head and runners with extensive flow bench profiling.(see above)
tappet shims.strengthened head studs.(see above)
titanium valve retainers.(complete titanium valve train)
custom cams ?? (somwhere near 280 of duration, while keeping similar lift to stock)
Turbo system: VeilSide/SPL GT-3540 turbo charger with uprated customised GT-42 compressor wheel and compressor/exhaust housings( somthing custom, but not that big)
A'PEXi Drag Vmax/SPL Pro intercooler (718mm wide × 258mm high × 156mm thick) with 70mm inlet and one 90mm outlet (custom made)
Custom 3.5" exhaust dumps, separate wastegate pipe into single 2.5" dump, exiting after front-right wheel.Custom turbo system oil feeds, water cooling lines(all custom)
modification of GT bearing cores to support higher shaft speeds.(same, or close)
GReddy Type-R Racing Blow Off Valve, with 3.0Kg/cm2 spring.(same, or close)
HKS 58mm external GT-Pro spec wastegate.(same, or close)
Drive train: B&M air shifter modified for control via MoTeC ECU.ATS carbon triple plate clutch.Cusco rear 2.0 way high-lock rate Drag/SPL LSD.(nothing even close to that setup, if anything, I'll go with a TH400 with a 3500 stall.
Custom solid engine mount system.(same)
IM Just Board!!! (me to)
There are few things here and there that are different. Some of which has to be, some of which is preference. I'll be using a smaller turbine and N2O, rather then just a huge turbine.
