I’ve seen tuning kits offering 150-170hp with not much more than CPU reflash,ignition upgrade, and premium gas. there’s one with a new CNC compressor wheel that gets to 200, that’s probably plenty scary in a old mini especially as it’s also making almost the same lb-ft of torque.

I guess it wouldn’t be much worse than the original configuration of the PRV, which did use a 120° spaced crankshaft, and as result also has uneven ignition timing with combustion occurring every 90-150-90-150-degrees of rotation, combined with the slightly twisted shakyness of an Inline 3. 
But damn, can it sound mean!
Either way, I have actually put enough thought into it to animate a very rough sketch of how the combustion cycle of a flatplane 90°V6 would look like:
Sure, the combustion would be even less even, but the vibrations could be pretty nicely balanced using a counterweight on the crankshaft just like in a V-Twin, and might sound like a double-speed Laverda Jota 180, so possibly mean

It’s certainly a rorty little engine

So a thought that came to me about a swap, one of my favorite looking sport compacts is the sport versions of the 9th gen corolla
here is a 2004 xrs, sometimes called a T-sport in some markets. The 2zz in it is a great engine but with only 170-210hp and maybe 140lbft it’s not as crazy as it could be.
Enter the 2GR-FE 3.5 liter v6, Toyota’s corporate v6 designed to replace both the jz straight 6 and the vz v6 engine families. On the right gas and with the right touches from lotus it puts out 280hp and 260 lbft from the factory. Couple that to a awd system under the frame of the Corolla and it’s a receipt for some serious fun, and not as outlandish as you might expect. Two later generations of Corolla (11th and 12th) had that engine shoehorned in for factory super gt racing, it would probably mean some front sub frame stretching to fit it under the hood and it would probably be nose heavy, especially if you dropped in the 345hp supercharged version with all the additional plumbing, but if you could keep the exterior looking close to stock it would be one epic sleeper.

I did consider the only EcoBoost I’ve ever driven, the 3.5L V6 out of a police interceptor. One of those in my 1994 SHO, all that extra power in a car that weighs 1000 lbs. less. The only concern is the maintenance required with that engine.
I hope you don’t mind me reviving this thread.
I won’t rest till I see someone swap the previous Focus RS’ 5cyl
into the current AWD Focus!

The Cadillac ATS-V is another prime candidate for an LS swap: it is clearly a match for European opposition in the corners, but although its twin-turbo V6 already cranks out plenty of power, it’s just not refined enough compared to its rivals’ engines. Replacing that V6 with the supercharged LT4 from the C7 Corvette Z06 would not only add even more straight-line pace (and the chassis can definitely handle the extra grunt), but also provide the classic V8 soundtrack this car desperately needs, complete with supercharger whine.
For that reason, slotting that LT4 (or at least a normally aspirated LT1) into a CT6’s engine bay would also make sense - the absence of a V8 option in that model is especially galling when you consider that the smaller CTS-V is powered by an LT4 as standard. And I don’t think a full-size Caddy without a V8 feels right at all.
The body is a Volvo 544 1960, the engine is a Transmash from a T55 tank chassie, the frame is homemade.
Front and rear suspension is from a heavy duty Chevy pickup/van.
A fair bit larger than the stock B16 , B18 engine these cars had.
And no, i’m not the one building it.

Doesn’t sound right, if the engine is from a T-55 tank, I would think a Lada would be more appropriate.
I wish our transport departments here in Oz would allow us to do swaps like these… Plus switch to a capacity based registration fee as its currently cylinder count based at the moment!

Idk if any regular performance engine would fit and if not then I’d fit it with an electric motor, into a Ford StreetKa.
Just imagine what it would be like to drive a fast streetka

Well the new fiesta st engine is a little 1.5 3 cylinder turbo good for 200hp, that would probably be pretty sporty in there.

I’m pretty sure the 1.6 in the ST is a turbo I4…?
Sounds like an awesome little engine. How about fitting it into a Mazda 2?
Like, create your own Mazdaspeed 2 when they don’t make one.
As a minor toyota fanboy I want that supercharged Yaris engine they just unveiled in Geneva a few months ago stuffed into a Scion ia (now toyota Yaris ia) which is how the Mazda 2 sedan is sold here. That would double the horsepower and I’m sure make for a interesting ride.

Excuse the double post.
Here’s a engine swap no one wanted but damn is it cool.

The latest Lincoln Continental is only available with a transversely-mounted V6 engine, so I’d convert it to RWD and install a longitudinally-mounted Coyote V8 from the current Mustang GT in place of the V6 to give it the prestige and performance it really deserves.
Also, a BMW i8 re-engined with a highly tuned, normally-aspirated version of the F10 M5’s V8 would feel more like the supercar it wants to be than it currently is with its limp-wristed turbo triple. Further information can be found here:
While I’m at it, I might go a step further by ditching the electric gubbins to save a load of weight and make it appeal to purists even more. Besides, there has never been a hybrid M-car yet, so the change I suggested might make plenty of sense… Especially to purists who miss the days of normally aspirated M-cars like the E92 M3 and E60 M5.
LS swap the world
