For some reason I believe he has a TII center iron.
Look at the pictures with the center iron in them.
In the 1st post, look at the last picture, there is a hole right under an next to the oil filler neck hole toward the front of the engine. Isn't that where the knock sensor goes on a turbo motor?
Just wondering if the ports in the center iron of turbos are different than the center iron ports in n/a's.?
Are they smaller?
I should know this by now.
