1999 996 C4 Engine Upgrade


Vehicle Information: Model: 996 C4; Year: 1999; Body Type: Coupe; Total Mileage: 80000;

Thanks for your quick response. You suggest going for a 2002+ 3.6 replacement engine but my mechanic said they're not interchangeable. Are the mods to upgrade to the 3.6 extensive? Is there some reprogramming to be done that would make this switch cost prohibitive?
