Hey , someone out there know anyone who makes upgrade parts for my 2.4l dohc GM motor . I'd like to go better than stock when I rebuild it . I need to do the rebuild soon so time is of the essence . If y'all know anything tell me please .  

Sorry my friend, but there isn't much aftermaket support for the Olds brand... But I did find a header unit and what it says is a cat-back exhaust unit also, but they're from Pacesetter (which usually says they are Cat-backs but are Axle-backs) which aren't the best in the industry when they have a line at the bottom saying. Might require modification and welding to fit. If you're going to rebuild the engine ask for Molybdenum or "Moly" rings. They last longer and can take more of a beating than the stock rings.  

Thanks Master_Shake029 thats more than I've gotten from anywhere or anyone else . I'd like to put a turbo or other forced induction setup on it but money is an object for me at this time . LOL . GM has a supercharger listed for my motor maybe I'll be able to afford it soon .
