Also worth is definitely relative/subjective, no doubt about that! But here's the thing, I don't think I'm alone in my perspective. It's probably going to be $7-10k for the swap (just guessing, pricing hasn't been released yet) to gain maybe 20-30 whp over a FBO E85 FA20. Not saying that's not a significant bump in power, but compared to the cost and issues that come with swaps, it's a tough sell unless you're talking about a blown FA20 situation. Again just my opinion.
On their FB page, they're pushing this swap pretty hard and I get that from a business perspective. But there's no point making comparisons that aren't apples-to-apples. If they're talking about a FBO K20/24 on E85 making 240 whp, then compare that to a FBO FA20 on E85 making 210 whp and you get a 30 whp difference. Or if they're talking about bone stock K24a2 making 170-180 whp, then compare that to a bone stock FA20 making 165-175 whp for a 5 whp difference.

Some people won't put up with inconvenience, and horrible mpg, of ethanol when looking for power. At least I won't. Not a chance, ever. haha. So a swap like this is quite meaningful/notable to me.

What's your "reliably" definition? To me it means track days without worrying if you're engine's gonna eat itself.
