My new Greddy turbo doesn't have a watercooled centersection like the stocker.... is it OK just to block off the hole in the engineblock with a block off plate an block the pipe by the lower rad hose to.

Also did the complete TB mod... same question there, can i just block the coolant lines at the engineblock?

 

yes, just block off all the coolant passages or you can run hoses to simply bypass from one end to the other.

 

i hate the bypass lines i have now so i will block it off :-D
