I'm a bigger fan of the Viper V10 swapped S2000.

Contrary to the expected popular opinion, I’m all for this swap. As much fun as it may be to rev the stock engine to ridiculous levels, I’d rather have a more balanced engine that has a fair bit of power everywhere rather than having everything up top.

I mean, the F20 and F22 engines are fantastic, but I get it. If you're looking for a lot of NA power with a broad range, then this is perfect. Sure, the F is lighter, but good luck producing over 450hp and torque without forced induction (it may be possible, but not easy).

Torque is good!

I prefer low rpm torque to high redline so....

Always wanted to swap the LS2 into a S2k and rebadge it S6000 with a vanity plate “LS2K”.

eh, it’s fine, certainly a tonne more power over the F-series it had. my only concern would be the added weight. some quick googling suggests 150-200lbs more, which could really throw off the balance.

anyway, the s2k is a hoot as is, but this is just a different kind of fun.

I suspect that with most of the engine behind the front wheels and I bet the trans is heavier so I’m guessing the weight distribution isn’t too much different. But it’s certainly something to think about.

I dunno, I’m all for LS-swapped Miatas (IMO they’re the true spiritual successor to the ‘60s AC/Shelby Cobra) but the S2000's engine was a bit more special than the Miata’s...

This got me thinking...

You’re talking 225 HP/L. The F20 already makes 120 HP/L, and the best production engine I’m aware of is the Porsche GT3 RS 4.0 991.2 which makes 128 HP/L. Both these engines also rev to 9,000 RPM. You could maybe eek a couple more ponies out but at 130 HP/L you’re really pushing the limits of what a gasoline engine can do. You could increase compression and switch to E85, I think that’s worth about a 10% power bump, but that still only puts it in the 140 to 145 HP/L range.

Even bike engines, which are incredibly high strung, can’t do this. The best, as far as I know, is the 2019 BMW S1000RR which makes 204HP at 13,500 RPM. That’s crazy!

And you can’t spin a 2.0L that fast because the valves are much heavier and I don’t think the valve springs could keep up lik e they could on a 1.0 L engine. So now you need to start looking at exotic things like penumatic valves. Since you’re now looking at engine speeds in excess of 13,000 RPM you’re probably going to need to go to a lighter billet crank, titanium rods, etc. to minimize forces on the rotating assembly. Y ou may also run into issues with the flame speed of gasoline, with the larger cylinder volume you may need to switch to a faster fuel like methanol to get complete combustion.

So basically you need an F1 engine !

Or you can disregard hp/L entirely and you focus on what really matters from behind the wheel: engine weight, engine dimensions (weight distribution), and power/powerband.

I wouldn’t care if my engine had 0.5 hp/L if it somehow also managed to weigh next to nothing and if it had the power I wanted and where I wanted it in the rev range. 

That’s where the LS shines. Its roughly 450 lb , short in height, and reasonably short in length. It can make over 500hp in NA form without breaking a sweat.

Hp/L only really begins to matter in specific racing classes - i.e. F1. When there isn’t a displacement limit, hp/l is a lot less relevant.

The f22 is lighter than an LS1, but it’s taller. It may even be longer. It loves boost and actually does well in NA form. But if you want a lot of NA power, it begins to show its limits.

Sure, the F is lighter, but good luck producing over 450hp and torque without forced induction

I was just riffing on how one would even make 450 HP/TQ all motor with a Honda F engine. And the answer is basically you can’t. You could make 450 HP, but not 450 ft-lbs of torque. And you can’t make that power in any way that would be streetable.

And you’re absolutely right, for a street car specific output doesn’t really matter. The F series is an amazing little engine, but it’s still just that, a little engine. The LS is a much more balanced street engine with both more overall power, and a broader, more usable power band.

Also, fun story, I went to college with a guy who had an S2000 with a turbo on it. The turbo really came on boost at about the same time VTEC kicked in (yo!). So the car was basically no power... ALL THE POWER!!! It was a fun car, in a terrifying sort of way.

They love boost. Unfortunately, the stock transmission isn't as fond of it.

Feeling the rage. If you want to v8 a little roadster, why not the miata? Is more common, cheaper, and is a car that's less about its engine

If that works then this should work too.

well, the ducati V4R (1000cc) makes about 234HP.

Wow, is it that much? I thought they were close to the BMW S1000RR.

I just googled and all I can say is Holy Shit!  That is a badass bike!

The 2020 S1000RR is up there now as well

Crazy! I can’t even imagine what one of those is like to ride. I thought my 07 CBR1000RR was obscenely fast... I can’t imagine it with almost 50% more power AND all the electronics to actually let you use it!

Then again I started working on my CB-1 last night and am pretty stoked at the idea of 55 HP right now!
