By eg84dr
- Thu Jan 14, 2010 11:06 pm #168528 i am going to be building and all motor d series motor soon
heres what im thinking
a d16z6 block stock internals
(thinkingh of shaving the crank) with p29 pistons in it
a z6 head gasket with a d15b jdm head on it i think that 11.7 to 1 for cr
im not looking for huge numbers just a fun dd
as far as tunning goes im planning on getting a p28 with data logging and street tuning
do you know where i could get a good base map to start with ?
any opinions apreciated
thanks

- Mon Jan 18, 2010 5:43 am #169194 The pistons will work in the z6, and what he said about the heads being the same is true. It is believed that the d15b head came with a more aggressive cam. Other than that they are the same.

With those pistons in a STOCK z6, as in no shaving or decking done, will net you about a 12.:1 CR.

I would suggest not shaving/decking unless needed to get a truely flat surface. If that happens get a slightly thicker head gasket.

- Mon Jan 18, 2010 5:53 am #169198 yup i dont think i will need to resurface the block or the head as they were in running condition just smoked alot
so should i use a z6 hg or a d15b7 hg i know the d15 is slightly thicker
with the d15 hg i will get a 11.69 to one and with the d16 i will get a 12.05 to one soo im thinking the d15 hg will do
anyone know bout the bearings? are all d series motors the same size bearings?

- Tue Mar 02, 2010 12:30 am #178574 Yea rhe z6 and d15b heads are the sane idk about the whole more aggresive cam thing tho. As for your CR shoulndt it be a lot higher? My d16z6 all motor build is gonna have I think 12.1 CR with D15B7 pistons. And a d16z6 head gasket. Your build sounds goood tho man ha ve fun with it

- Tue Mar 02, 2010 5:05 pm #178696 i did look on the other thread that had about the p29 pistons in it, it did say the valve reliefs are in the wrong spot... you would prob have good luck with the b7 pistons from the compression nums. u said in ur other posts... :thumb: what rods were you going to use?
