So I got this CRX and it has the 1.5 fuel injected engine in it and I want to bore it over. Is there a place to find out what the sock bore size and stuff is on it? Or what would be a good bore size to go with? Also what commperssion ratio should I go with?

 

with stock sleeves you don't want to go crazy with it..40 over the most....But i would do 20 over just incase i have to rebuild later so ill still have some material to take off..

stock is 75mm

 

yea I know, I think I might go 30 over, and I might try 10:1 compression, maybe even 11:1. Idk, I need to think it over. thanks.

 

does boreing even make much of a noticeable difference in Honda engines? i know its done to increase displacement size but does it help any?

 

Not on stock sleeves.
