okay okay i know its been covered alot but, i'm trying to make a decsion right now. i have 63k on my s4 NA motor(still runs strong). now! would it be more ideal to do a rebuild and turbo the NA block or just swap the Turbo II engine?

 

I say if you're that set on going turbo, go with a TII swap.

 

Yes I'd say the same of you are going to rebuild and turbo just do a turbo swap.

 

How about reading the FAQ, seeing what is involved with both, and then making an informed decision?
