What Intake Manifold to get?

[Louie91]

I'm looking to get a new manifold. But I want opinions, experiences, thoughts.
I'm building an N/A B18a1
Mods: Stage 2 Cams, Hi comp Pistons(12.3 I think), Header, intake and exhaust.
Future Mods: 420/550cc injectors with a fuel rail.

I'm stuck on either skunk2 and Victor X.

Skunk2

Pretty sure Victor X is more than you need. And you're stock fuel rail will be fine n/a. You will also need to look into a fuel pump. Are you going ls/v?

Skunk 2

Both are good but I'd go with skunk2

The VictorX is not a good choice for any engine under 250hp and spins less than 9k.

Performer X would work better for that setup and RDX injectors.

Thanks guys this forum has really helped out. Sorry for the late responses, too. I settled on the Skunk2 Mani and no, I am not doing ls/v. Another question I have whether I should get a different throttle body or if my stock will do just fine. Should I? If so recommendations for my build. I was thinking maybe 68mm or 70mm. Thanks again.

stock is fine for you.

Pro tip: if you log manifold pressure, observe MAP at redline. If its pulling more vacuum than atmospheric then you have a restriction on the intake (including throttle body). If you observe 0psi all the way up then your intake system is doing its job.
