hey, i recently found a 4g63 7bolt turbo. the man said everything runs, good top end but there is a knocking noise when it goes over 2500rpm towards the bottom end. he said its a "crankwalk" now is that a big thing to fix? how much would the fix be and if that is the problem would there be other things goin out on it? and the engine is 200. another thing ive seen a dodge colt gt AWD with a 4g63 engine. what are your thoughts on that? would that be a difficult swap to do? would you have to modify the engine bay, suspension, driveshaft, idk if colt gt come awd. ya thanks for reading
