i have a d16z6 and head want to use the d16a1 pistons for higher compresson going to go with oem pistons and rods and crank so which one doe i use z6 rods and crank or a1 rods and crank sorry if this is a noob question

 

does anyone know what rodas and crank i need to use in my d16z6 block with the d16a1 pistons for high compression

 

try searching first if you find anything then bump

 

i have searched everywhere i kno to look on tha internet cant find anyone help anyone know????

 

Z6 rods and crank.

 

thank you civic spoon do you kno anyone running that setup up or similar and what kind of hp numbers their making again thank you much

 

you would be lucky to break 130 whp

 

i don't know what size the pistons are in the z6 but on my a6 i was gonna run the zc pistons(pm7) with a thinner HG and those pistons it said your compression would go from 9.4-1 to 11-1 keep in mind you HAVE to run higher octane gas as well.The higher octane gas part made me not go with this setup.As a friend stated you could get the same amount of HP from a intake or header as you could with that upgrade and in the end the H/I would be a lot cheaper my 2 cents......

 

isnt 130 only 3 more than a y8 even with high comp damn i thought it would be a bit more yeah i knew i would have to use the high octane

 

will eventually have agood im and a good hedder have cheap ebay hedder right know but want to start with the high comp thanks alot guys

 

the hp is measured at the crank when the factory does it so its much higher 130hp would be at the wheels

 

a friend of mine had a z6 with a cam and zc pistons in an ek, and that thing could move for some resin. would beat ls hatchs and some b16 civics as well. compression would be around 12.7:1

 

oh ok what is the y8 stock to the wheels 110 ok yeah that makes a lil more since now

 

didn't mean to be dick earlier but seems like you got a pretty cool project so many people ramp on the d series high comp but i think it seems like a jit deal

 

I had a Y8 that put 111 to the wheels

 

For what its worth I built a High compression D.
A6 block,rods,crank,P29 pistons,ported A6 head,2 layer cometic HG,Gude 007 cam and SK2 adjustable cam gear,tuned on a chipped P06.
Although I don't have any dyno numbers it moves out with authority.
Compression calculator showed 12.1:1 with my setup.

 

hell ya for the d series dont get me wrong wouldnt mind a k or h or even a b but my buddyn had a bunch of d **** layin around i got a d16y8 in my civic now so gonna build up a lil junkyard motor see what i can do for chep thanks alot guys

 

IMO Y8 motors are junk...oiling problems and more.If you can find one use a Z6.Far better motor IMO.

 

You need to figure out WHICH D16A1 pistons you're going to use first.



86-87 are flat top pistons and we call them "PG7" and they yield more compression than stock Z6 pistons.

88-89 are dome top pistons and we call them "P29" and they REALLY yield more compression in a Z6 engine.

There are compression calculators that you can play with by punching in different heads, pistons, gaskets, etc.

I built an 11:1CR D16A6 on-VTEC with a stock cam and head and it literally ran better than any LS swap my friends owned, but I also built a close ratio tranny to go with it too.

 

with a6 pistons im at 10.4 i should be good with 93 octane i think but with the a1 pistons im at 13.6 will i be good with 93 or will i be det.. without race gas

 

Was my post invisible or something?

Ohh my [freak]ing god! My eyes exploded!!! You bastard!!!!

 

i had to laugh about that as well... i scroll down and what do i see... BOOM! RIGHT IN MY FACE haha

 

PM7/P29 (JDM ZC/USDM D16A1) they both are listed under same so i figured they give the same bump in compression come on now im the noob aint gotta get pissed hahah but seriously thanks for the info guys

 

i will prob go with the dome pistons unless there is a prob with the valves if i put an aggressive cam in it the pistons i was told to use was d16a1 cause "they have valve relieves so you can put a big cam no issues" so as long as the dome ones are good prob want them
