I heard of people putting a6 heads on d15's and it would come faster than a stock si?? is this true, i also heard that one guy locally ran 15.1 with this setup and i was wondering if it was a good idea to try it or not, has any body else try this, also is it better to throw a6 pistons inside the d15 block and try it after?? so lmk what you guys think and thanx in advanced for your help

 

bump anyone??????

 

The stock si is a 1.6L and the d15 with a A6 head is still a 1.5L. It is a bit faster than the stock d15, but not faster than the stock d16a6. My friend did this and he raced my brothers stock si, and yeah you know the rest.
