my new pistons

robtec · Jan 9, 2004

these pistons are great,they sit betwen the a6 and pm7 piston

they are the pg6b,they are from a sohc zc motor.they have the same compresion height as a p28 pistons(30),but it has a 1cc(est)piston dome displacement,i think they would yield a 11.5cr in a stock z6,unlike the 12.0cr the pm7 give and the 10.0cr of the pm6.

i can get them for $160 totally new with rings :wink:

That sounds like a pretty decent deal.

robtec · Jan 9, 2004

i check ,and this pistons are from 87 d16a1,they have a 30mm compresion height and a 1 cc dome. check in here http://www.knology.net/~jediklc/D.htm to see what this pistons can do for your motor,remember to enter the correct Piston-to-Deck Height using the Piston Deck Clearance Formula and if you have a milled head,all you have to do is enter a smaller value at the Head gasket Thickness,for example if you are using a .037 3 layer z6 gasket and you head is milled .010,enter .027 instead of .037.

The pg6b also came in the 86-87 integra d16a1. They have a 1.81 compression height and a 1.5cc dome.

1.81??i measure it,and it have a 30mm ch,identical to the p28s,about the 1.5 cc that might be right, becuse i measured them,and i came very close to that.

DOHCDX · Jan 9, 2004

yeah, WTF is 1.81 CH? what units?

if it is EXACTLY 30mm CH, then that means you have to use the .00 p28 piston to deck height. so, that will yeild a 11.7:1 CR in a bone stock d16z6. 12:1 with a 2layer HG.

11.7:1 more or less,that's true, i have pics of this pistons,the pm7,the p2p,the p28,all sitting next to each other.the problem is that my camera is fucked,and i am having problems downloading the pics to the pc,but soon expect a few pics. :wink:

1.81 inches. wtf else would it be? 1.81cm? yeah it has a .000 piston to deck cleanrance just like the z6.

1mm=.03937in.
30mm=1.1811in.

the ch in in.is 1.1811, not 1.81

correct me if i am wrong :lol:

where did you get the pistons from?

robtec · Jan 11, 2004

i get them from a local distributor,they are replacement pistons from japan,the rings are nippon.

i can get them for $160 with rings,the problem is that i am from Puerto Rico,and i have never deal over the internet,how can i make this work??

PRcivicHB · Jan 23, 2004

Sorry to reawaken the thread but dont the A1 and ZC share the same piston? I didnt think they were different..

What part of PR you from Robtec?

ZC are domed. A1 are not.

Im from P.R. too

San Juan area

bigmrg · Jan 23, 2004

o think you will find that some zc pistons were domed and some were flat top pg6's depends on the year

PRcivicHB · Jan 27, 2004

So the ones that he is getting are the flat tops right? Because domed ones (from my understanding) would raise compression even more? right?

Flat tops are PG6?

Domed would be PM7 and P29?

Right or wrong... (Im trying to learn, sorry for being annoying)

<---- Ponce, PR but i live in Miami now...

bigmrg · Jan 28, 2004

yeah thats right

si los pg6 son de integra 86 y los pm7 son de integra 88,son lo mismo q los p29,y soy de cayey
