Looking to boost 2.4L LD9
Wednesday, October 26, 2016 8:47 PM
Hey there guys! I am the owner of a lovely 2001 z24 Cavalier, and I really want to turbo it, but trying to find a good build guide is daunting...

I was just wondering if anyone can link me to a good turbo build guide/ a good turbo kit for the LD9 engine that would be absolutely awesome! Thank you!

No real guide. No kits new anymore. You can buy manifolds, and piece together everything else, which is cheaper.
