The stock crank will take that hp easy. And the stock piston are REALLY strong too. All you need to do is tune right. The main advantage of any aftermarket piston is the slight wieght saving.

the rods are the only weak spot in the block.

Thanks for the info.

I also heard that the aftermarket pistons are only a little lighter than stock.

So why are people doing them...... just to do it ??

BTW, I need to deinstall the complete engine to do the rods, right??
(I´ll not do it myself but would like to know what to expct....)

Thanks,
Michael

I went with forged pistons because of the shot of Devil Juice that's being thrown into the equation. But if you're going turbo only, I think the stock pistons can take the punishment.

You can't go wrong with Carrillo H-beam rods, either.

I've yet to hear of anyone breaking a crank, and people have made in excess of 1,400 crank horsepower on it, so I wouldn't worry.

The stock pistons and rods may "take" 1,000 horsepower, but they won't do it for long.

The Cosworth pistons are excellent, I highly recommend them. As for the rods, it's personal preference more than anything else. I'm going with Cunningham Titanium for the latest build.
