I'm replacing the engine in my FD. Are there any extra things I can remove? I am planning on taking out the A/C (doesnt work anyways) and all emissions. Are there any sensors I can take out that I don't need that won't throw a CEL? Any warnings and issues that I might need know? Any help and comments are welcome.

go non sequentail and you can get rid of the rats nest under the uim. Use 1/2 watt 330 ohm resistors from radio shack and wire them into the plugs or if you have apexi power fc you can just bypass them. Pm me if you want more info.

I would advise against not getting rid of the ps. It really isnt a big hp gain and is WELL worth it when you are just driving around town.
