My completely new SR20det is almost finished being built and I am switching from my current 550cc STI side feeds to top feed injectors. I was planning on going with 800cc STI top feeds because they are so easily accessible and my plan is to continue using an Enthalpy tune.

I have seen the STI type, skinnier injectors and the denso type of fatter injectors. I searched but couldn't find a good answer. Which would be the best high impedence top feed injector for my configuration?

Wiseco 9:1 pistons, 86.5mm
Eagle rods
ARP head studs
Apexi 1.1 head gasket
BC264 12.0mm cams
JWT cam gears
Greddy valve springs, BC ti retainers
GT2871R .64 @ about 18psi give or take
Blitz i-sbc digital boost controller
Megan tubular exhaust manifold
Greddy intake suction kit
Greddy down pipe
Greddy hot pipe
Greddy FMIC
Greddy BOV
Greddy oil pan
Z32 MAF
stock intake manifold
HKS top feed fuel rail
Aeromotive FPR and push lock lines
Enthalpy tune

Thanks in advance for any advice.

Might as well go with 1000cc it gives u room to upgrade.

Yep. Best ~1000cc injectors out there by far.

As a follow up, I ordered the 60mm long Injectory Dynamics ID1000 with 11mm top caps to fit the billet HKS fuel rail I will be running. I also bought the plug adapters so that I don't have to splice the wiring in; they will be plug and play. They should be arriving Thursday or Friday of this week. Thanks all for your advice.

All I have to order yet is an Aeromotive or Summit inline -8AN 10 micron fuel filter for under the hood. I was tempted to run larger line from the fuel tank but it's overkill and not necessary I guess.
