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.

Saying a stock K24 will make 75 whp over a stock FA20, I don't think there's any legitimate apples-to-apples math that gets you there (or anywhere close really).

The merits of the swap are valid enough to stand on their own. No need to play loose with the numbers. That's all I'm getting at.

An internally stock K24 with intake manifold (required for RWD unless you want the TB facing the firewall), header, and tune will make around 230whp on pump gas easily. 75whp over an FA20 is an exaggeration stock vs stock, but if you look at the cost to make 230whp N/A on an FA20 the swap starts looking really good, especially when you factor in how easy it is to hit ~260whp on pump gas with a K24.
