How much HP can a 1st gen 4G63 can make??? Is the 1st gen the one that can make the most HP or is there another?

Thanks

 

they can take like 450 on stock internals.

 

Some of the overseas EVO's have a stronger version of the 4g63 that can take around 500hp in stock form. But they're really exclusive...alloy blocks, moly coated pistons, titanium rods.....i think they were the EVO6 or EVO7 special edition models, but i can't remember which.
