I've heard of more than 30k miles on 2.3s. If you maintenance your car when you're supposed to and all that stuff, it should last just as long as you would expect an OEM engine to last.

I'm not saying they are misinformed, I'm merely saying our point of view is clearly different. From what I understand, the casting is more or less identical and the cranks are both forged. One lacks oil squirters but that is of minor importance. This would also give me the capability to turn around and sell a functional evo 63 block for what.. 3-500? That would effectively pay for the 2.4 crank but is it worth it considering I'd be in the market for a new waterpump? I'd also have to pray the timing is done right

The main difference in the block is that the bore is larger and the deck height is 6mm taller. Also, there are no oil squirters. The oil squirter debate has been discussed in this forum plenty of times. The way I look at it, Mitsubishi did not add these for the fun of it. They spent time and money in testing and designing these into the block. If you are going to do any type of racing, these should be added to the 64 block. The main purpose is to lubricate the wrist pin and cool the bottom of the piston.

63 blocks are becoming scarce. A good running short block is worth roughly $1,000 depending on miles, compression, etc... A bare block around 7-800 and crank around 2-300 depending on buyers and whatnot.

A 2.3/2.4L has the higher stroke but of course it'd be built with quality internals. On the other hand it would see 500-600 WHP and some gruesome track days. I never beat on my cars but I expect them to perform. From what I gather, 30K more or less would be a good approximation

As for life expectancy, that will all depend on the abuse, tune, power, parts, but with a properly build motor 30k shouldnt be an issue. My last evo went 75K on a 2.4 making 500 on pump until the oil pump failed. It did see a lot of abuse which is why I think that the pump failed.
