Yes, better off buying a 4A-GZE and following the path that others have walked before you, padawan......4A-GZE already has the nice low compression pistons. However, it you really need that many horses from a 4A series motor, even with an SC14 you may struggle to get there in a cost effective manner.
A better bet for that amount of power is to again start with a 4A-GZE but drop the Z for a T. Sounds easy when you type it.
Again plenty of threads on this forum under '4A-GTE'. Search, read, learn and enjoy......
