I'm rapidly gathering parts together for my 3.0L M20 build, first step was obtaining a complete M54B30. I'm saving the crankshaft and rods, hoping to use the stock M20B25 pistons as I'd rather not change the bore. I recall reading about this setup quite a while ago, but haven't seen any real details in searching for the last few weeks.
I know MM uses the B30 crank and rods along with their 86mm pistons for their 3.2L builds... would the same crank/rod setup with 84mm pistons give me working 3.0L? Or are the stock B25 pistons too tall with those rods and that crank?
Thanks for any knowledge, I'm planning on testing and confirming anyways for future builders but any tips going in are greatly appreciated.
