to my knowledge the 4g63 is not a direct bolt in for the 2g eclipse. i have heard its quite labor intensive and expensive. correct me if im wrong....
and back to main thread if the manifold came off a 1g eclipse 4g63 motor then it shouldn;t directly bolt on to a 420A motor. they are completely two different motors. but who am i ? once again if anyone has seen this then correct me.
