does anyone have dyno numbers of before and after a built bottom end or any links to them?:)

A built bottom end won't make more power. It is stronger so you can push it harder (more boost, etc)... but there shouldn't be any significant difference between a stock motor and a built bottom end motor with everything else being equal.

For power... build the top end. Heads and boost make power... strong internals just live to tell about it. :D

wouldn't boring your cylinders to 86.5 mm and putting in carillo rods that weigh 200 grams less per rod make a little more hp than the stock setup???

Yes boring and stroking (increasing dispalcement will make more power. Lighter rods will let you rev faster and higher... if you have the valvetrain to suport it.

With Supras boost is how you make power.

he said "everything else being equal" . higher compression can also help, but that doesn't qualify as equal either.

Thanks Turbosupra... :D

Higher compression will make more power... but high compression and turbos/SCs (boost) don't go together.

well, they do and they don't. on a race car, 10:1 or 11:1 can be used with 30 pounds of boost or whatever. its all about the detonation threshold, which can be greatly increased with high octane gas, or even alternative fuels.
