I don't think the intake manifold has to be enlarged. If it does, it probably isn't more than a few MMs. I know it's definitly bigger than 60MM. I will measure the opening sometime this week when I take the TB off to do a couple more adjustments.
Yes, I did buy the TB from my local dealership.
I should get some pics later today. It's raining now and I don't want to melt.
