I'm thinking the d15b7 block cause i here a lot a about them?

Mimi me Honda civic 92

What are you planning to do to the car? Race? Turbo? No racing, just to get around town, and very reliable? For racing I would get a d16a1-3. They're not the biggest/most hp engines but I believe they have around 150 hp. Which is good for a little civic. Plus you can throw a turbo on it and it can still be as reliable as a stock honda engine. I like having a decently quick, reliable car rather than a faster car that can blow up at anytime. For bigger and badder you can get a b16 (I think) which has around 190 hp but if you turbo that it can cause problems quite easily. It's been awhile since I've read about Hondas so I'm not sure if I'm 100% correct. But I'm about 90% :p anyway best of luck!
