Im completely new to the eco tech world but I’m building a 2004 sunfire 2.2 auto into a dirt track race car. I’ll will be building an engine this winter for next season but I would like to know some easy bolt ons to help with some hp to finish this season any and all help would be appreciated
Le5 intake manifold, lsj exhaust manifold (assuming you need to appear stock via the rules)
Add a tune and that should net you a few extra hp.
