Ok i'm still trying to get a little more information on an engine swap or upgrades to make a k20a3 into k20a2 and i came across an article at neuspeed that says the only difference is a few bolt-ons and a upgrade camshaft. now i was told that the HEAD had to be replaced along with a few other parts. i need to know if the head needs to go or if i just nedd the cam, and the little internals... any expertise would be greatly appreciated. ih ope to have the swap by the end of this summer and any help to reach my goal would be greatly apreciated.

 

head and ecu
