Other than the obvious gain from a 2.0L to a 2.3L and being able to run higher boost levels, butby replacing the crank will it eliminate the crank walk problem or will it still be a possibility to happen. This probably has been asked before but I couldnt find it on a search.

 

the crankwalk problem is caused more by the oiling system design more than anything.
if you rebuild it you got a long way to go before it'll happen. if you wanna get stronger main bearings so the thrust bearing wont wear as easilyget King race bearings and they wont wear out. the thing is with them is when they do wear, they wear the crank just as much. but normally the rest of the engine is done for by then anyway.

 

dont do it. Go 6 bolt. 7 bolt can go out without any warning or obviousreason.

 

god you guys worry too much.
the thrust bearing in an engine doesnt just magically wear out suddenly.

 

exactly. If your going to be replacing the internals then it should be a good amount of time before you have anything happen. But of course the issue does still exist and with time it may still happen.

 

my take on it is that if you are going to be spending the money to sroke the engine, you might as well go 6 bolt... TheEngineer has one for sale cheap. This would mean that you wouldn't have to be w/o ur car while the build is in the process, you completely eliminat the crankwalk problem, and you raise the value of the car. But if you are set on sticking w/ ur 7 bolt, going w/ a new crank, and bearings will dealy your crankwalk problem for at lest 80-90k miles i'd say. I've never heard of an engine walking before that number of miles.

 

Said the 6 bolt owner.
