these are a set of srp pistons for a .10+ bore. compression is 10.5:1 in a d16z6 and 8.5-9:1 in a zc. dish tops. they have 400 miles on them. they were removed because the adjustable cam gear wasn't properly tightened and one valve barely kissed the valve relief of th piston. it was then taken to the machine shop and fixed. its 100% usable. there was no real damage. no skirt scuffage, damage what so ever! retail $4XX. get them for $220 to your door. pics speak for themself.

Would you be willing to trade the pistons for anything? I have B18A1 full bottom im trying to get rid of

 

too bad they're high comp or id be all over them.

 

What comp would these put out on a zc?

 

no trades, i need to sell these to finish sleeving my block. the compression on a zc would be close to 10.5:1 it could be higher or lower depending on what machine work you do, as far as decking the block, resurfacing or milling the head, what type of headgasket you use(thickness) , all these things play a key role. steal this bitches b4 they are gone

 

that's odd, are you sure?

ZC's have domed pistons stock, i would think these ones would result in lower compression.

do you happen to have the part # off of them?

 

****, I may be perfectly in line when I say you are teh wrong.


Those are 9:1 d series pistons if I ever saw em. (and I have.)

 

the guy whom i got them from says they are 10.5:1 in a d series which d series? he did not say but i put them next to another set of srp pistons that ARE 9:1 and the tops aren't the same these have higher tops that don't recess as deep as the 9:1's. so im not sure now but you do have a point there. there is nothing wrong with them

 

wrong about what then?

i said they didnt look like 10.5:1 pistons.

 

actually i just checked and the info was correct these ARE 10.5:1 in a d16z6. the tops are dish type because if you look at where it says piston cc's you'll see it says -3.8cc with means they are dish tops.
