Change cylinder head in 97 civic-Need Help
Can any one tell me if you change the cylinder heat of 97 civic Ex to an Si, how much hp will be gained if at all? Do you have to change the ECU, timing and fuel specs similar to Si? Is this change worth or just waist of money? Some one has told me that if you do the above modification, then one can gain about 20 hp. Please educate me about this subject?

Are these all canadian models? If so, the EX for the 96-00 is just a canadian Si, ergo they are the same engine and cylinder head and all other internals. if this is a US EX to a US Si, they are different engine families and it won't fit. I don't know who you heard this from..

This 97 civic EX is canadian made (I think it has D16Y7 block) and would like to gain some HP by replacing it with Si head (say D16Y8). Is this trouble worth the gain in HP? What is the actual gain? Or are there any better alternatives; that is cost vs HP gain?
Thanks in advnce for your reply

well, the Y7 is non vtec, so your swapping on a vtec head. so yes, you would be gaining vtec and around 20bhp. But you would have to do the necessary changes to convert to vtec. Like obviously the ecu, and other vtec components that i don't know offhand like a solenoid and other crap.. someone else might know the specifics better.
btw i thought EXs in canada were mostly cars brought up from the states? This must be a 4 door right?

Nope, CDN Ex's aren't the same as the US Ex's. CDN Ex have D16Y7. Our EL's are more comparable to the US Ex.Originally posted by ~$eanith~
