out of all the d series..which is better..??

 

for boost that is

 

i like the z6

 

yeah thats what i was thinking...what bout the jdm d15b..??

 

i would still go with the z6

 

For boost the best D series is a D16A6 with an aftermarket cam created specifically for boost.

VTEC is less than optimal for boost, but if it's just a street car on modest boost, it certainly wont hurt you.

Agreed.

 

If I HAD to chose a D-series block for boost, I would go with a JDM D15B or USDM D15Z1. Since the rod ratio on these blocks is MUCH better than the D16 (1.62 vs 1.52), side loading will be MUCH less. This will result in better durability - ESPECIALLY with stock sleeves. Other D15 motors (ie D15B7) have a rod ratio of 1.58 - not as good as the JDM D15B or D15Z1. But still ALOT better than a D16.

 

One of the best engines honda has ever created is the d16 that came in the ef si's. love those engines.
