EcuTek/Uprev Tune - OK, not like you have any other options. The real decision is "whos gonna tune it?"
Greddy High-Capacity Oil pan - OK
ARP Head Studs - L19 only or dont bother, standard ARP studs torque limit is too low
Cosworth Head Gaskets - OK, i didnt even know they had HR/VHR gaskets
Darton sleves - Never do this to a VQ, it only introduces room for error to fix a problem nobody has
Wiseco pistons - OK
Carillo/Eagle rods - Carillo OK, Eagle probably OK but scarey
ID/Bosch injectors - OK
Brian Crower Stroker Kit - Pointless
CJM Fuel pump - OK, so long as its large enough for your power
Fuel system - OK
Return fuel system - OK
Valve body upgrades - I pretend the 7AT doesnt exist so I have no opinion what to do with it.
Billet crankshaft - Waste of money
New spring and retainers - Consult JWT what to do with the VVEL heads based on your goals
Fuel pump voltage stablizer - I assume you mean upgraded wiring to the pump? If so, that is good and should be done for anything larger than a 255.
