Oh boy, now you've done it. Cross-forum flaming is sure to follow.

Blows my mind that the guy is so argumentative with someone who actually owns an Isuzu. But if he knows of a yard with these prices I might just tag along:
Engines are $300-500 for any engine in the yard, $50 for ECU and $50 for complete harness. Transmissions are $100~200 if I recall correctly for any trans in the yard.
And comments like this would suggest he has no idea how significant the oil consumption issue really is.
Facts about the swap that can not be argued.
-Better gas mileage
-Less oil consumption
Lastly I'd be interested to know where he found that "the 6VE1 has been built to 813hp." If that's true I shudder to think how much oil that guy must go through between changes.

It seems that most people who post these types of threads end up seeing their dreams killed early on when they run into a problem they can't solve or run out of money because it's more expensive than what they thought. The sad thing in this situation is that the guy might actually be knowledgeable enough to go all the way through with it, in which case he won't find out what a mistake he's made until the very end when the oil consumption is just as bad as before and the improvements in performance and fuel economy are nominal.
