anyone swap 7afe to 4age/4agze before? Options

[syaoran60085]

Well i found a 95 Celica ST ST200 with 7AFE Engine in it, i probably getting that car as well since it's Manual Transmission. so that makes it 2 Celicas i'll be owning. Giving my brother my Automatic Celica GT 5SFE.

I just want to know if anyone swap a 7AFE to 4AGE or 4AGZE(even though i know it's more recommended for street driving with good end torque) engine before and the results of it success?
I know i read the Feasible and Non-Feasible Engine Swaps Topic said, "Celica with a 7A-FE(USDM ST) because both engines are A-series engines. This engine will bolt right up to your stock USDM ST(AT200) transmission."
someone care to explain what that means in the parenthesis? does it mean it's easier to swap because the motor mount can hold the 4AGE/4AGZE as well or is it something else behind that meaning?
I'm planning to do engine swapping in my dad's shop if it doesnt require any welding or special setup to put the 4AGZE in the ST Celica.

Much info or help is much appriciate from the ones that have good knowledge and experience
