I've been doing some research on the different options, but I still can't decide which one would be the best way to go. I'm looking for 500+ whp on pump gas and what every more I can get out of race gas

. I'm leaning towards the 2.3 because I miss the low end torque of the Spec V, but I'm open to suggestions.
Here is what I’ve come up with so far.
Eagle 4g64 crank
Eagle H-beam rods
Pistons not sure which company but .020 over 9:1 compression
P&P head 1mm over Valves W/ Manley valve springs
of course ARP Head and Main studs
272 cams
SCE Copper Head Gasket
Other supporting mods I would still need to get
JM Fabrication SMIM
Turbo Concepts 70 trim stage III A/R (.63)
DSM link
850-1000cc injectors
Inline Walbro 255 (I have an intank already)
I think thats it besides the normal rebuild parts.
