For all you mini me peeps out there which of these combos are the best

1. d16a6 block d16z6 head
2. d16a6 block d16y8 head
3. d15b7 block d16y8 head

 

did i do that right...prolly not

 

Isn't the d16a6 the strongest sohc block made?

 

A6 and Y8. Head provides a little more compression than the Z6 and is newer, so most likely lower mileage.

 

what no love for the d15b2-y8 combo?

Lower displacement. Unless somehow its an even higher compression ratio, its got a .1l to catch up. Any displacement you get is good in our engines.

 

the dx motor has 9.6:1 compression..the A6 only has 9:1.

The d15 has a better rod to stroke ratio..ill be it minimal..but its still better..and d15's are alot easier to find.

id go with the d15/y8 combo..but im partial

 

i saw someone run 13.9 on a a6 block with y8 head. That is hella sick

Is that compression change from block or head design? I think it should be noted that a z6 or y8 head will increase compression, does it do it the same on the d15?

Also, if it does raise the comp similarly in both, will a .6 comp difference be similar to a .1l difference.

I dont think you get as high of a CR with a d15 block. With a Honda headgasket d16y8 head with a a6 block it should push out 11.2:1 CR. I am not too for sure about the .6 compression difference.

 

you will not get less compression just becuz its a 1.5L. Honestly i see no difference in a 1.5 and 1.6. The only difference between a dx motor and an si motor internally is the cams, and a lil higher compression in the 1.5's. that is all.
