The short blocks are 100% identical. The STi has better pistons and substantially improved heads, but they're still not forged. It also has an 11mm oil pump on it.

Most of the prices comes from the other parts you listed, i.e. 6-speed, brembo brakes, slightly bigger TMIC, etc etc.

The heads are pretty much the same with the addition of exhaust AVCS which is essentially useless. I believe they also share the same oil pump now too.

Sooooo basically the tranny and tmic are the weak links? Well and the garbage stock tune of course.

If you read my post stage 2 FAQ, I go a bit deeper into it, but yes, those two and the stock BPV at elevated boost pressures are the weak links. I think the tranny will probably outlast the motor, but I'm still not aware of much hard evidence of the 08+ tranny limitations. I just know that 500wtq is enough to blow them.

Yeah, but I don't know how we'll it holds up below that. I only know 500 is too much kinda like saying "I don't know what the speed limit is, but 120 is too fast."

There's no magic number for busting a tranny/engine. You can do it on stock power levels if you're stupid enough.

Like Nimbus said, it was pre October 08 build dates.

I started a thread asking that very question a couple years ago, one guy in Canada blew one up, but it turned out to be an obvious and one off defect, the rest of the replies were guys complaining about burning their clutches up. I have 70K on mine now, runs like a top (fingers crossed) but I did replace the clutch at 60, but hey, it is the car my wife learned how to drive stick with, but hey, stage one, turbo, awd and someone learning to drive stick I was surprised it lasted that long.

I wonder if he is confusing the STI ring-land issue with the pre October 2008 build date spun bearings?

Sorry, I wasn't paying attention I guess. I guess I was mistaken as to what the problem was, but I knew I remembered something about the early 09 cars.
