not on yet unfortunatley since hahn racecraft is dragging their ass on the release of the 2.4 liter kit, they went to the stupid twin charge kit for the 2.0 cobalt 1st. garrett is only supporting the 2.2 with this kit but it would bolt to my 2.4 with different tuning. the ecotec block is the same for all 3 motors with different internals so any kit that comes out i can use for the most part. as far as getting a few hard parts and going custom i would but i would need a shop that can do it in 3 days max, make it look very professional like powdercoating or polishing the pipes. and dyno tuning the tcm and ecm to fine tune it for less price than buying a kit. i dont think any shop around here would be up to that challenge so thats why i dont go that route. plus custom kits are more for huge hp gains when i cant make more than 250 wtq due to that being the tranny’s breaking point until i have the time and money to upgrade that which wont be for a while.
I would wait until you can do exactly what you want along with the supporting mods that need done instead of going halfway. Do the supporting mods first to make it bulletproof and then pay a local shop do build you exactly what you want.
