The ultimate inline-four?

!!!error: Indecipherable SUB-paragraph formatting!!! . I'd heavily mod it to be much, much more reliable and long-lasting, as well as make it a 1.6 (maybe even 2-liter, but that's pushing it too far), and I'd pull the turbocharger out in place of more efficient twin split turbo setup. That, or I'll just get a modern Bimmer 4-banger and mod it until it becomes a rep of the ultimate I4.

Yeah, that's right. I'll just get a modern Bimmer 4-banger and mod it until it becomes a rep of the ultimate I4. But hey, a man can dream.

Nothing you build yourself will rival the M12. Nothing you have a shop build for you will be able to combine the output of the M12 with the reliability (as in, something that can go hundreds of thousands of miles between major service) of a normal engine.

So. Take an engine whose defining characteristic is a vertical powerband caused by overcoming an artificial displacement limit with an oversized turbo, and bore it out to a more reasonable size requiring less boost/stress and yielding a wider torque (and power) curve?

You my friend have entered the world of "no replacement for displacement".

Veyron SS, Venom GT, Koenigsegg, SSC, LaFerrari, and P1 disagree. No bowed cylinder walls and tossing the block after one track session in any of those.

None of those cars are powered by a four cylinder.

Which is why they can combine the output of the M12 with the reliability of a normal engine.

The OP wanted a 4 cylinder that could combine those things. Are you trying to point out that this is not possible? Because I already did that.

Oh I posted a separate response to his modification ideas...my point here was that you can certainly get this kind of output with reliability, you just have to use a more sensible layout. The limitations of the original engine (4 cylinder, tiny displacement) are artificial constraints.

I believe the ultimate inline 4 is the 4G63 from the EVO.

I was initially not a fan of the new bimmer four bangers as they sound like shit at startup, but I've been impressed with the one in my wife's car. Very responsive with the two scroll turbo and plenty of power. It seems as most of them are making about 260-270hp stock. With a Dinan tune you get over 300 hp.

Yes, yes I did.

I know just the crew that's up to the job.

But yeah. That's gonna be an immensely tall order.

You're right.

I concede.

for me, it has to be the 2ZZ. One of the most Greatest engines Toyota has made in the last 18 years (next to the JZs, the V10 from the LFA). 4 banger with a hella high recline and the equivalent of VTEC. Yes.

The ultimate inline four would be either the BMW F1 turbo engine (that is in the picture), Lancia Triflux or the gigantic engine used in Fiat S76.

You have all of the Internet at your disposal and you post a picture of a toy? :|
