My daily b16 turbo with SC34 swallow a piece of the cone filter and the compressor wheel get damaged.

I found three options.

Garrett .57 trim cast wheel for $149.00
Kinugawa .57 trim cast wheel for $65.00
Kinugawa .57 trim billet for 139.00

I'm leaning to the billet wheel, but I want to know if any performance is gained against the cast wheels.

Thanks for the help.

 

Billet wheels lighter, so in theory it could give you a bit better boost response.

 

The weight isn't what makes them work better. It's the design configuration. Billet wheels have been in heavy duty applications since the mid-90s. It was due to the durability of the wheel based upon the content.

 

And theres a slight chance cast wheel can have a better wheel profile
