I just had a motor put in my 95 DX. It had a stock D15B7 in it and my car is a Canadian model. My replacement engine came from Japan and on the block is stamped D15B and has 16 valves. How can I tell what exact engine it is? How many HP, etc.?

This new engine was guaranteed to have less than 50,000 miles on it. I think it's nearly new. I've driven it about 1,000 miles since the swap and the oil still looks and smells like you just poured it out if the new container. It also has considerably more get up and go. My old engine got about 37 mpg while this new one is giving me 33 so far. I think it's because I can't keep my foot out of the gas. My crappy old civic is now fun to drive.

Thanks..

 

the d15b is equivalent to the d16z6 or the y8 i think has vtec and about 125 hp vs your dx which only had 102hp.... with non-vtec you got one of the best d-series though
