XT6 Turbo Heads

Featured Replies

What is the differance between the EA82 and EA82T heads. I need to know so I can modify my XT6 heads for turbo application if the modification can be done. Does anyone have pics of both so I can see the differance side-by-side?

Scott,

I believe you think there is some difference in the combustion chamber volume/shape.

 

This is not the case and the comp. ratio is set by the piston crown..

 

The heads in question are identical

except for a water and an oil port which the turbo unit has.
