I have just gotten my eg, and already ideas have begun spinning about what to do. I have found an intact LS integra engine that will need a rebuild. I have considered doing the full swap, but i have also considered an LS/VTEC. If i do this, which one would be a better head to use-B16 SiRI, SiRII, GSR, or B17? I need a lot of useable power, as i will be auto crossing. I will stay NA of course, no nitrous or turbo. I have considered SC, but decided against it. There will be some time/budget considerations, but I want full-on opinions. Is there anyone here who has already done this? Are there any warnings that i need to know about? Do you guys have any other options engine wise besides a b16 I or II that would be a good swap for a primarily autocross car? would building the Dx engine be a better option?

Thanks in advance,

Mike
