Td05 20g will make more difference right? And prepare to run into the fuel stumble issue, so better have extended fuel line mods ready if u wanna bigger turbo. 3port boost solinoid, turbo inlet r must have imo.

800cc inject is more than enough, oem ecu cant handle bigger injectors efficiently.

Happy modding!
