I don't know, I'm assuming 25mpg. But the real nice thing would be simple no leaks, no real worries, assuming there are no issues with these conversions. I have no idea. The sound of both are really nice. The low rumble of the v8, the fan sound and then the burbles and pops of the 930, the loud yell on boost from the dump pipe or the 930 is hard to let go. And the rush of boost would be tough to say good bye to as well. The aircooled engines are a little finicky no? Gotta watch closely the afr's and the Oil temp as well. With all the oil cooling there is less room to add ac, but with water cooling there is a giant eye sore up front in the Frunk. There is really no room for my crap that usually goes there.
The ls1 is lighter. And more powerful too. I mean with 5.7-6.0 it better be right? But it's lighter.......soooooooo. And well packaged. Cleans up the engine bay well. But I like the look of the 930 turbo better. And it sounds cooler while running. Hmmmm
