I am thinking about building up a D16A6 engine running N/A what is a better bore to have Bore 2.972 with 11.0:1 compression, or Bore 2.963, or 2.953 ??? This is on the pistons of coarse. Im not really sure what is better any help would be appreciated.

 

WTF >>>???
well i hope i can help you out. The stock bore for a D16a6 is 75mm (correct me if I'm wrong). You can go up to 76mm on stock bore on NA but thats sorta risky.
If you were really seriouse about going NA D16a6 then check out http://www.exospeed.com & instant message ExospeedAMc

 

for n/a bigger is better.

 

ok, i dont really know what i am saying but worth a shot.
i think if i remember you can only bore out to a 79 with stock sleves. and it you wantto go into the 80's you have to get it resleved. but there was a ok amount of post about things like that. you can use LS pistons and what not, just gota get your block resleved.
exospeed is a good please to look. also try dseries.org havefun! and PLEASE PLEASE let me know what you do, i really really want to build a d16a6 also!!! i even bought a extra one, haha. see ya!
