Hi all,
would hope that someone will guide me thru my Evo 5 engine rebuilt as my ride recently encounter burnt bearing problem.
Here are some question which i really hope to know :

1) Anyone knows how to tell whether is the cranks is in good working condition?
What is the turn down point when assessing the cranks??? I don't want to get a crank which will ruin my engine soon...
2) Can a stock Evo 5 valvespring (New) able to withstand 7,200rpm with GSC S2 cams and do i need to replace the stock valve seats as well?
3) Will it lag for GSC S2 cams matching with an Evo 5 stock turbo?
4) Since Ted has advise to flush all the engine oil passage can my mech just use petrol to clean the head & block after the overhaul and how about the turbo? Do i need to flush or clean the turbo as well since its oil cool to?
A Million Thanks
