Im goin to pick up a DA9 but it needs a new tranny and a new block ,but the head is a fully built jg head with crazy jg cams, i dont want to put another b18a block on it cuz i thnk i'd see a nice torque gain from a bigger displacement, if someone can tell me if this is possible and what i'd have to change that be great... thanks

 

It will all bolt up.

 

sounds like a good plan to me
that si tranny will pull extra hard; but your top speeds sucks *****....
