I am looking to doing a engine swap for a goal hp of 300-400 hp. I would like to get a LS1, but am concerned of the weight and if enough weight could be shaved of to compensate the engine/trans. The car for now and for a while later is going to be a Daily Driver. Any way I go its going to cost around $8K USD, with either the swap or a built B6 or any other I4 turbo. So for all you racers out there what would be the best option for more power. I have a few races under my belt but I want to see what you would do if you had the chance to do it all over again with a clean start.
