I'm almost positive they will fit with no boring or any other major mods, but I am just wanting to make sure that they will.

 

yes they will fit, they share the same 75mm bore.

 

i wonder what the c/r would be and if there is any clearance issue

 

I've discussed this before.

if you want to put d16 pistons in a NON VTEC d15, you better make sure you get rods from the VX 1.5 vtec-e motor or the jdm sohc vtec d15b. If you use the non vtec rods, the piston will sit down in the hole about 3mm too short due to piston/deck height differences and rod length differences. thus a waste of time and a loss of compression.

 

yes it will fit, suppose to yield higher comp ratio too

read above, they will sit too low in the hole.

 

OT: but where can i get some d16a1 pistons for my rebuild.. its going in an a6 block of course..

 

your acura dealer.

or http://www.acuraautomotiveparts.net 1988-89 d16a1 p29 pistons.

 

hes not putting vtec pistons in his b7, hes putting zc pistons in his b7. why does the vtec rods matter ? well my friend put zc pistons in his b7 and it was faster, but i guess it was something else that made him faster after he put those pistons in

 

because the d15 and d16 pistons have different heights. a d16 rod is longer then a d15 rod by about 3 mm. when u put the d16 piston on the shorter non vtec d15 rod, the piston sits lower in the hole.

did i say anything about vtec pistons? i said vtec rods. the vtec d15 rods are different then other 1.5 non vtec rods. you could say they are similar to a 1.6 rod in nature. they keep the piston up in the hole where i should be, so it doesnt sit too low in the hole. sure u may see a lil gain. but, not worth the trouble if the piston is gonna sit too low. i bet your friends car would be faster with proper rods.

 

If you were to be using a regular d16 piston on your d15 rods, your compression would be around 8.6 but since you are looking to use zc pistons, which are domed, you would raise your c/r to 10.71.

 

arite i want to put zc pistons inside of a z6 or get some pistons to install into the z6 what pistons can i use that... and what compression will the a1's/p29s yield me!

 

I already answered that question, a1/p29 would give you 10.71 on b7 rods.

 

what about the pm7 pistons in the z6

 

12.03

Nice. Yeah, I didn't want to use the D15 rods, I've always heard about problems with heat dissipation, and I wanted the ZC rods for more strength because I am planning on running boost. Oh well, it was worth the try. But they will fit fine in an A6? (PM7 pistons/rods)

yea, the PM7 pistons/rods will fit in the D16A6.
