For those of you that have seen the civic that I brought back to life Im just thinking about changing a few things with the motor. Just so everyone knows what Im talking about here is a link to where I built the car & a link to where it is forsale.

Anyways it has a b7 block, z6 head & y8 head gaskett. That puts me at 10.1-1 compression. I put the car up against my roomates supra that has the jdm 7m-ge in it & he didnt pull on me too much off the line but, once moving he would kill me. True enough I was easy on the car bc I just got the car together. So what Im thinking is changing the pistons. Im going to pull out the stock b7 pistons & go with some p29 out of the 88-89 integras d16a3. If I run the y8 head gaskett also it will give me a cr of 12.045cr and if I remove the center layer of the head gaskett it will give me a cr of 12.504. Or the other thought is put on the y8 head with the p29 pistons & that would give me a cr of 12.667cr & at 2 layers 13.179 but, as a dd I think that will be way too high of a cr. Is the y8 head alot better than the z6 head? What is the highest cr I can run on pump gas? Would 12.667-1 be to high for pump gas?

 

I wouldn't recommend over 12.0:1 for a daily driven sohc on 93 oct.

 

you gotta retard the fuck out of ur timing but it can be done

 

how much better is the y8 head vers the z6? Im pretty sure the y8 cam has a higher lift but, could I put the y8 cam in the z6 head?

 

reped also well I cant rep u john it says I have to spread the love lol
