CiViC_eK24 - okay, you and me are in same boat.

Alot of your questions you've already asked, I have!!! YAY!!! Finally after countless threads i've read, and a couple hours of my day so far. i finally sign up.. and find one of the questions in another search, but no answers.

Ergh, the internet is wonderful! But so.. ergh, aggrevating at the same time. I've been on this site, and civic-eg, and hondaswap.com.. but i still have questions!!!


My question for you, have you figured this one out yet?!

wait, obviously there is a difference, otherwise, why would they be two different numbers right?!? Soo.. then the question should be.. what IS the difference?!

the p28 is from 1992-1995 Honda Civic EX/Si / del Sol Si and 1992-1995 Honda Del Sol Si/Civic Hatchback Si/ Civic EX and the p30 comes in the 1992-1995 Honda del Sol DOHC VTEC EG/SiR. the only diffrents that i know of is the the p28 is a sohc ecu and the p30 is a dohc ecu...thats all i know.unless they control how much gas is sent and the rev limeter are diffrent so guess thats all i know

get the ecu that matches your engine. A p28 will let your car run, but it won't run to it's full potential. Unless, the p28 is chipped for your engine. But still, get the p30.
P28=soch vtec
p30=dohc vtec
