easy 500 rwhp?
Easy, cheap, and 500 RWHP with decent street manners just don't go together. Especially all motor. If you want that kinda power with good street manners, you are gonna be looking at more cubes, and that ain't cheap by any stretch of the imagination, especially since you will start breaking everything else (clutch, rear, etc).
Horsepower isn't cheap, unless your sucking on the blue bottle.

He wants 500rwhp ALL MOTOR!
More cubes is the only way. You can get close with AFR 205 heads and a big cam with ported Fast 90 intake, QTP LT headers, underdrive pulley etc...With that you could get close to 480 rwhp.
to all you
You'll need to swap out that engine for bigger cubes or just add on FI or nitrous.
