I’ve been compiling a list for my 2007 Chevy cobalt lt with the L61 Ecotec. I have been planning on eventually pushing it past 500 horsepower, and I need to find a forged crank. I have been able to find everything else I need, ie; pistons, rods, cams, turbo, all of the piping, bearings, etc.. The part that I have had the hardest time with is finding a good reliable source for a forged crank. I know eagle used to make one, but I haven’t been able to find it. Any help is appreciated. Thank you!

 

I think your only option is to find an old eagle forged crank. As far as a know nobody makes forged cranks for these anymore. Stock crank is pretty well supported. There are people in here that know and hopefully chime in about how far you can push the stock crank reliably.

 

Thank you for that, it’s unfortunate that they don’t make them anymore. I’ll have to look into it more, maybe a custom crank.

 

The stock crank will hold double your power goals.

 

There is this though: https://www.alibaba.com/product-deta...491777420.html

 

2.0 swap with an LNF/LDK crank and LSJ rods/pistons
