Here I am considering some possible options for tuning my 4AFE compared to swapping a 4AGE. Yeah there might be more trouble but I thought of having the fun to experiment and save the trouble of going through the engine swap registration. Hope can get some input if anyone have tried or seen any of these options done:

1. Head swap with Blacktop 20V
Benefits: Cheap. Less stuff to change (pumps and all), piston are lower compression so easier to future turbo.

Doubts: Pistons less...
