first of all the ecotec appeared in 2003 into J-body but 2002 into n-body at least in canada, maybe before in the US.... You need the complete harness, new clutch and flywheel assembly, new lower right engine mounts, new pcm and the front pipe of the ecotec, I did numerous ecotec swaps into cavaliers and sunfire, on the 2000 to 2002 it's pretty easy..... but on the older ones you need the complete harness from the ecotec car + the cluster + the gaz tank with the fuel pump + the charcoal canister + the exhaust + upper and lower right engine supports + pcm + engine + tranny + the shifter and cables

I think I said all you would need to know to do a ecotec swap and of course you need to do the security light trick so that the bcm and pcm relearn their new codes on the 2000 to 2002
