4.10 vs 4.3 in 20B N/A FC

Christopher... The Torsen can handle the power. I have a 20b NA in an FD and am using the stock diff. If you are going for better acceleration, I understand the choice. But you should probably also run the speeds in gear for the wheel tire combination you have in relation to the driving you're going to do. In other words, if you're on the streets, where is 40-50 mph? Is it in second? How high in rpm? Where is 65-90 and how much room in gear do you have over and under that? I actually went the other way with the 3.90 R&P because of the speeds in gear for my driving.
