they say the bore is 76mm? isnt the stock bore 75mm....

 

[Steven.]

most aftermarket head gaskets are 76mm bore. its normal and safe to use.

 

[TiiM iiS l3eAsT]

k just makin sure....

 

[Genuine Rolla]

Nice updates.

 

[Autoworks]

HKS Beaded 76mm gasket is definately the way to go

Blowing your motor must be ok with you to be running a basemap without ever checking it out for over a year...

Thats way past stupid in my book.

well, it hasn't blown yet.

and i don't have a pcv setup

That piston in your DOHC ZC w/ a stock head and block deck is going to get you down into the 8.3-8.4:1 C/R if I remember correctly.

 

[TiiM iiS l3eAsT]

no it wont....it will be around 9:5:1

hey green what will my ratio be with those pistons and hks bead headgasket?

 

[Steven.]

no it wont....it will be around 9:5:1

hey green what will my ratio be with those pistons and hks bead headgasket?

like i said it will be lower then rated, due to the ZCs larger head CC.

according to http://www.knology.net/~jediklc/dcalc.htm
(HKS bead HG is .027in thick, or .7mm

8.37426174942519:1

if you machine a little off the block and maybe the head, it will raise it up a bit, if your shooting for 400whp later it will be fine, but DD on lower boost will be slugish.


actually, you will want the HKS Grommet HG, it will raise your compression.

Thanks
I was about to make a point, but forgot what I was about to say...

 

[Steven.]

what will that raise it to?^

stock block and head with the grommet HKS, will be around 8.4:1 or close.
machining a little off the block to raise the CR up a little bit more to atleast 8.8-9:1 would be best.

the reason your compression ratio in the ZC will not ne what the pistons are rated for, is becouse they are made for the D16a6, they have a smaller combustion chamber CC then the DOHC ZC,
ZC: 43.80cc
D16a6:38.00cc

 

[somejaykid]

dude that's awesome man

 

[TiiM iiS l3eAsT]

thats gay u told me it would go down to 9:5:1 but whatever.....as long as it works ill be fine i guess.....

 

[Steven.]

no, i said thats what they are rated for, but will be lower in the ZC. i said this before your bought them.

they will still work, its actually a benefit if you plan on running higher HP later.

 

[TiiM iiS l3eAsT]

so how sluggish will 8:4:1 be? i mean is it really that noticable?

 

[Steven.]

you will notice it might take a little longer too spool up, but if you raise the CR to 8.8-9:1 it wont be as bad.

still not as bad as putting vitaras in a DOHC ZC, they you have aroudn 7:1
