I have been reading up on a couple build thread and the info thread. But those are pretty old and the pictures no longer work.

For this EMUSA build on a stock K20A3, I'm trying to retain as much bolt on as possible. So for fuel injector and fuel pump. Would I be okay with a stock fuel pump and just upgrade injector?
Only need around 220-250whp. So I don't think I will need the 4 bar MAP sensor. Can I just run it thru K pro and not have to wire and gauge? Any old member with experience please charm in.
