Ok so I got a lot of free time out here, Im planning on doing the fallowing to the Z when I get back to the real world.

LG longtubes, an LSX intake, and LS1edit. On top of my Vararam and loudmouth Im hoping for 420 rwhp with a decent tune. What size injector should I use with this set up? Thanks in advance.

You might want to research the LSX intake for your car. Seems to do better on larger displacement engines. Much money for small gain if any. Injectors also depend on how much pressure you place on them such as with a boost-a-pump or higher pressure pump. It is a marriage. I think 30's should be OK but there are others on the forum with more NA experience than I have. Too large is not good either. Good hunting and and get home soon and safe.
