I am seriously looking into getting an SZ (comes with a GE) and na-t it. Im looking to make around 600-700 horse power in it, with a pt61. Will i run into any problems with the bottom end of the engine? i.e rods, pistons, etc. Will i run into any problems with the head? I know i will need a new fuel rail to convert it but what else?? Anything will be much appreciated!
