which head would you go with or stay with original setup?

well after all the work done to the wagon the car still wont work right.
turbo D16a6.
supertech valves, springs, and retainers.
after a week of a new tune for some reason two valve broke off. just took off the head and found major damage to the head and pistons. it might need to be torn down again to be repaired.
i dont think i can salvage the head. so should i get another A6 or something else.
if its something else what would be pretty much a bolt on with little mods on the D16?
any suggestions?
and what would need to be done to make your suggestion work?

im not sure where to go with this. i was thinking i may need to bite the bullet and pay for the fix.

they say the D16y8 from 1996-00 Civic Ex is a direct bolt on.
how much stuff from my current setup is resuable?
since i got the skunk2 intake manifold and fuel rails all the supporting mods, will this Y8 still be bolt on?
is there any difference in wiring witht his new vtec head?
all of the intake will work on any sohc head, the y8 has the best stock intake (arguably as good as skunkz on boost from my experience), you will have to pickup a new vtec dizzy and vtec solenoid which will need to be wired in, only a few wires if I remember correctly. if you are not running a programmable ecu then you'll also need a p28 or some other vtec controller.
Do you have a dyno sheet from when it was tuned showing things like A/F ratios?
so far he is a very well known tuner, and once he says its not the tune then no one will believe otherwise. i am not a tuner and not a mechanic so there is backing there.
he says that its a mechanical failure.
the cylinder far to the passenger side is the culprit. it looks like the bottom round part of the pistons on the intake side broke off and bounced around in the cylinder. it also looks like fragments got into the other cylinders too. there are scuff and small nicks on the cylinder walls. im not too sure how bad it is. i dont have the trained eye to determine it.

do i need all four new pistons?
here are the piston parts and the spark plug that was damaged.
im not sure if the head is still reusable.
im not sure if can just hone the cylinder walls or do i need to remill the whole thing.

quick history.
drove for about less then 2k miles with brand new internals.
tuned again because of bucking sensation from first tune,
about 1 week on there with 2nd tune with less then 50 miles.
wasnt driving fast either. only about 40mph. then engine drops dead.

got to go. off to work.

checking oil pump, bearings, balancer
all that jazz...
why do you recommend the z6 over the y8?
i is it really hard to get it to work?
Have fun in the turbod wagon. They truely are a blast to drive. I love when these punk kids pull up to me and start honking there horns to race and the light turns green and I am gone they never knew what hit em. All they heard was my exhaust and pssssst as I pulled away.
D16A6 block
D16Z6 head
vitara piston

will have a CR of 7.36
or just play around with the d16 calculator if you would like to increase the CR. just my 0.02c

i actually want lower compression, not higher.
because witht he y8 head your gunna need an adjustable cam gear just to get it truely to TDC and if i remember correctly it raises your comp ratio quite a bit more.
if u can pic up a complete z6 go for it and throw some vittaras in it my buddy ran a vittara build with an sc61 ran 12's and had a very basic set-up.
You want somewhere in the middle, say 8.5:1. If your tuner can't tune it to work then fire them and find someone who knows what they are doing. You should be even able to run higher compression than that if your tuner knows what they are doing.
since this might work. is there a link that will show me the how to do and what is needed to be moded and replaced to make this work?
also whats a good price for a clean z6 head?
he says its from a 98 ex civic.
What I'm saying is that with the Vitara pistons, you'll have about 7.5:1 compression using OEM length D16 rods. That's too low. If you go with the longer FJT rods, your compression will be back up to a reasonable level for boost (still lower than OEM).
Figure out a way to get him to get his story straight. The 98 EX had a Y8 head stock from the factory (96-2000 Civics). The Z6 head was only available on the 92-95 Civics.
i hope its in good condition as i dont know how to really look at it for any damages like warpage or missing small parts.
