Horsepower gains from within?

After looking at the forced induction I'm left wondering if there is a way to build horsepower from within. Where can I go to find higher compression pistons, stronger rods, and larger valves? Is there a a company that is producing high performance engine parts for the 1GR? or website?

 

Here you go: http://www.tacomaworld.com/forum/performance-tuning/79094-performance-mods-1gr.html

Some people have done some N/A mods on X-R Underground, but it appears that most go for F/I.

 

LC Engineering sells high compression pistons, forged rods, that paired with an X-1 for tuning, maybe add a set of cams, I bet you could push close to 300rwhp N/A.

 

You dyno'd almost 290rwhp with intake/headers/exhaust, and an AFR tune? The loss in our trucks is only about 12%-15%, which would need 280-290rwhp to get 330bhp.

I think there is a mistake somewhere. Either in the dyno correction factor, or the drivetrain loss variable.

The highest dyno I've seen N/A was Jaxchrisfla at 255rwhp (intake/headers/exhaust, x-1 with full tune). Which is still short of 300bhp.

 

Thanks fellas (or gals). I'm going to build an engine for natural aspiration, if I'm not happy, at least it'll be strong enough to handle the SC lol. I think being addicted to alcohol/drugs would be cheaper lol
