So I have a d15b8 in my 97 civic dx. My awesome 70hp well I'm gonna just say we all know... So while I'm working on my rebuild for my bseries I was thinking of doin a mini me setup. Just oem swap on and leave it. Know I've read all these write ups and I've gotten some good info but wear I lay is between the z6 and y8... And its true differences... So in peoples experience because if you have done this before you can truely have an opinion what would you do? Straight up z6 head or y8 head on my block? I do love high end power and read the z6 head would be better for that but the y8 head yields a little more compression and I love that two. I know these heads are very close in numbers and i probably won't really feel a difference but i want to just get the best option so since I can't decide who can sway my mind on one...
Hey quick question is the z6 in and ex mani's the best oem fkowing...?

 

What ever gets more response too I'll probably go with that... Thanks..

 

Why not just leave it how it is. And save your money to put into your b series

 

"High end power" and "Z6/Y8" do not belong in the same sentence.

 

Just pick one man, not a ton of difference performance wise.

OR

Which ever is cheapest/easiest.

 

Exactly.

 

Head bolt wise the z6 is easiest, Y8 you will need one different headbolt, it needs to be shorter and believe it goes to the head hole that is near the vtec solenoid. Its been a long while since I did this so research it some. Also you can use the dizz that you already have and not spring for one like for the z6.

 

Well the bseries motor won't be done for awhile its not a typical build. It's not even going in the car I have it would be a crx... and i got some extra money so I'm just tinkering with the dmotor... I can get either head fairly cheap.... And i know its not really awesome power but its Deffently better then the 70 I got so I'm kinda looking for peoples experience in which one is the better one... I mean one has to be better then the other and i can't find any actual specs on performance to which one yields more Hp/tq... And ya i read the same thing with the bolts but that's not a big deal to me.... It's quite simple I just want to know anyone's first choice... Is the cam better in the y8? I've read that the z6 in and ex mani flows the best for oem. I was thinking y8 head with z6 in and ex mani's... How does that sound to anyone....

 

I would just do the y8 head, IM, & EM

 

Ok cool I was kinda thinking the same.... Thanks...
