engine question

[xAchillesx]

what is the first ting to go on the 2v blown engines? As far as internals go, IE rods, pistons, etc. And I am talking the first to go with a good tune? Just curious if one thing is prone to give out before another or not>?

the connecting rods are the major weak link on stock motors. they are stronger than average stock conrods, but they should be replaced with forged conrods with any competent buildup. the pistons are hyperutectic, they are fairly strong, but again should be replaced with a good buildup. for a crankshaft, get a forged cobra crank, they are good to about 700hp.
