Thank you so much
I had plan to swap a 4AGE I always wanted to have it under the hood but nobody recommended it. It's hard to maintain i guess. Engine Dealers and most of the people who were running or who had a 4AGE experience said that you'll get fed up from the knocking issue because you should run it on HI-Octane and it'll give you low mileage.
7k, 4age 20v BT, 7afe, 3sge Beams, 3sfe
These engines were on my list. As I wanted economy and power, so everyone suggested me 3sfe. I loved 3sge Beams but then again its a performance engine and it won't be good on mileage so, had to let that go.
Going for 3sfe now
