Dude, no they are not... U live in York? Come to Phila or Allentown and I will show you my chipped P28 used in my EG. I got B16 block, GSR head and custom turbo kit. My P28 controls my DOHC motor just fine...

There is no need to get cocky, act like an adult. You look even worse now cause you are so adamant about you being right, when everyone on this site knows u can use a P28 with a DOHC motor...

Stop acting immature and calling people names... I'm not trying to be a dick (like you), but you need to learn some computer forum etiquette.
