With a N/A engine, would it make sense to use a 70MM BBTB or porting the airram? I was thinking that when I get my BBTB down the road, since I'm going N/A, I would probably want between 61-65MM. Would 70MM be better or worse with N/A?
No, you won't use a 70MM with N/A.
Yes, porting it is a good idea, then you never have to take it off again. Same with Ceramic coating. Get it done NOW before you intall it. Even if you never, EVER plan on going to a 70MM, consider the following.
1. You need to get that nasty bump/cut out of the way on the left hand side.
2. It takes about 20 minutes to get 2MM off if that, take it off now.
3. Do it now, you may sell the thing one day it if you have it coated, at least it's out of the way allready.
61 is what I have and I want to try a bit bigger. 70MM would be OVERKILL for us N/A.
