Not really, I started the swap at the end of the drivable season for our area and the car has spent most of the time parked, currently finishing up the turbo setup and will have it at TX2K - just as transportation unless I run into some huge snag.

This is a blacktop swap just in case that wasn't clear. I don't have the exact differences in weight, but couple things to balance out, you have two aluminum heads on the FA20 and only one on the 3sge, I just packaged up a full set of FA20 heads yesterday and they weighed 88lbs boxed. I feel like the 3sge head will be slightly lighter than that. I am throwing out numbers but would guess 50lbs or less on the 3sge fully loaded head. So saving of 30lbs to give to the over weight cast iron block. I don't have full weight of an FA20 block but have the bare block numbers somewhere in the office and have other 4cyl cast iron blocks to get a rough idea of weight and will report back next week. Now the 3sge will definitely have the weight higher distributed.

I think a lot of that has to do with proper tuning. I will wager we will get similar gas mileage with proper EMS and tuning.
