I had a dream about this with two F20Cs last night. No joke.

What’s the most ambitious project you’ve ever undertaken? How about designing and building a V8 engine based on the Honda K24 from scratch?
A passion project of Craig Williams, the engine–dubbed the K48–is still in its design phase, a few features stand out so far: 5.0-liter displacement, stock K24 heads, a flat-plane crank, naturally aspirated and turbocharged setups, and engine mounts the same size and shape as those found on an LS3.
Williams aims to make the K48 capable of over 700 horsepower and 10,000 rpm.
For more information and updates on the K48, check out Neutron Engines on Facebook and Instagram.
So, what car would you put the K48 in? And would you keep it naturally aspirated or turbocharge it?

Whats driving the decision to put the exhaust side toward the center of the V and the intake outboard?
In reply to ProDarwin :
Significantly reduced turbo lag and I believe heat management as well (one area vs 2). The Ford 6.7 Diesel is the same way for those reasons.

Hot V's are great for turbskis.

I've studied Hot V's for decades, never thought about turbocahrging them. Hmmmm
Not to mention a pair of turbos poking through the hood like an old-school supercharger would look awesome.
There is prior art here in motorcycle engines. IIRC about the only thing that gets retained are the heads. Very good heads, of course, but it's a pretty significant undertaking. The names that come to mind are RST in the UK and Hartley in the US. I did a bit of work on an RST V8 once.

I've thought about different ways of making this work many times before, and would love to know what solution they came up with for driving the valvetrain on the reversed head. Assuming no balance shafts, I'm also curious what the 2nd order shaking transmissibility into the chassis will be with typical LS engine mounts, since it will be 41.4% stronger than that of the (balance shaft equipped) 2.4L I4 it's based on.

If I remember right, there's ford Flathead guys who've done that to get around the difficulties the 3-port exhaust imposes.
The Valkyrie engine from Aston Martin is also a hot V. Honestly I think all the newest- and probably last- V-shaped gas engines coming out are hot Vs, partially because it lets you cool the exhaust temps right away before they form NOx.
The modern day Audi turbo v8s are all hot v's. Along with the 7.3 powerstroke and 6.6 dirtymax. I don't know about newer diesels.
This K48 seems like a crazy cool undertaking. I would love to hear what it sounds like at full trot.
