Yes, I agree... I'm already heading down this path. New dump/front already ordered, PFC ordered, bigger exhaust ordered, will have to get cam gears (would prefer poncams + gears, but $$$), probably end up with new turbos shortly. Its a bit of a trap. Still, I figure if you get small enough replacement turbos you can still have them near their effeciency range whilst only getting 250-odd rwkw but still have headroom. That way you can keep the stock fuel system (and cams), not have a laggy ho, and when funds allow additional upgrades get a nice extra kick.
At least the rest of the stock parts aren't a ticking time bomb.
