ls-v-t, stock sleeves, 15lbs, aftermkt rods pistons, gsr main girdle mated to ls block, block guard, the works.

what i want to know: 50mm wastegate, same mm bov. logical or not if im planning on sleeving the block later on down the road?

all input is welcome(neg or positive)

 

LOL and you rebuild transmissions?

Do you think you need a 25mm gate/bov? Your questions doesn't make much sense. I would use a 50mm BOV/Gate even if I had no plans of sleeving the block..

 

ok thats why i asked. im new to the different sizings and what not of this kind of ****.

 

You can never have too much wastegate. And a Tial 50mm BOV is the industry standard for pretty much every application.
