can d15b7 pistons be used in d16a6????

 

yes

 

YEA

 

no bore is bigger in d15

 

the pistons alone, yes i believe so, but not 100% on that. if they are attached to the stock d15 rods, then definitely no. they have a smaller rod journal size than the d16.

no, it's not. all d15/d16's have a 75mm bore. the stroke however is what changed to add the .1 liter. from 84.5mm to 90mm.

 

i thought d16s were 75mm and the d15s were 75.5mm

 

^^ no both the same

 

stock d-series = 75mm, bored 20 over = 75.5mm, 40 over = 76mm.

 

cool thanks guys!
i have a d15b7 laying around and my d16a6 is in need of a serious re ring, so from what i have found i belive that with the d15 pistons on the d16 rods in the d16 motor it should be a lil bit higher compresion

 

assuming the wrist pin size is the same then it should work..

however, according to this site the c/r will be siginificantly higher..

from 9.1:1 to 10.5:1

if that's accurate then i really don't see the stock ecu being able to run it properly.

edit: this other site.. http://www.knology.net/~jediklc/dcalc.htm

shows a change from 9.1 to 9.7, which honestly sounds more realistic. unfortunately there's no way to know which one is accurate, if either is.

 

IS THERE ANYWAY TO USE THE PISTONS AND RODS TOGETHER FROM THE D15B7 IN THE D16A6???????? I REALLY NEED TO KNOW!!!!!

 

the best thing you can do is try it out yourself. i tried using dohc zc pistons in a d15b2 and the zc pistons stuck out. so your best bet is probably no.

 

d15's have a differend crank journal size than the d16's
