Most Powerful 2.0 Na Motor?

[ORB 227 1 Cars]

What is the most powerful (BHP) Normally Aspirated 2.0 (or less) inline 4 PRODUCTION engine?

 

I can't think if anything to top the S2000 Vtec?

 

No reason for asking, just was thinking...

[Schern 0]

No I think you're right if restricting size to 2.0. There are more powerful N/A cars per litre I think but S2000 is the most powerful 2.0 iirc.

I think its likely to be the K20A for bhp, not sure about the torquiest though.

[S@m 156]

Probably is going to be the F20C in the s2000 with 247hp.

 

K20's 'only' have about 220 at best afaik in some dc5 integras and jdm civics.

 

I don't think that any other manufacturer is close to that.

 

EDIT - having just had quick a look at wiki it seems that the f20c held the production engine record for specific output regardless of total displacement until the release of the 458 Italia.

It is a spectacular example of the folly of figure chasing though (officially it was 237bhp btw). It's just about the most gutless feeling 2 litre production engine around and I'm a massive Honda fan! It's basically a big bike engine, but not really up to the job of hauling a car around.

The f20c is so epic I actually looked at fitting one into my e36..

 

Must still be the most powerful 2.0 though.. Didn't realise it also held the best power per litre though, well until the 458.

I doubt you want one in an E36 given the characteristics Sandy described, you want a V8 in there.

 

Talking of M3's, the CSL is not far off at 360bhp/3246cc, but with a much nicer sound and greater drivability.

 

Also there's the very special GTR at 493 bhp from a 3997 cc V8

[MiniGibbo 142]

Yeah mines 351 at 1250kg and does make for a good drive..

 

 

I sacked the idea of the f20c off as it would have been nice being a high rev screamer but you'd need 300hp to make it worth while and that would cost a fortune.

[Batfink 201]

a bolt on supercharger kit is not that expensive on the grand scheme of things.

[MiniGibbo 142]

We talking the f20c still..?

 

As boost on that is sacrilege IMO.

[dcc 855]

not sure what the cc law is on the wankle engines in the rx-8's, but arent they 260bhp ish from a 1.6?

[stef205 92 1 Cars]

1.3 the rx8 is I think

What's the most torque from a 2.0l name production engine, as it left the factory...

[Tom Fenton 1,547]

Now that's an interesting one. Clio 182 is 200Nm/147.6ftlb.

[ORB 227 1 Cars]

That's not that impressive TF, as the XU10J4RS has 145lb/ft - but then I suppose the GTI6 is a but torquey!

[welshpug 1,666]

bit of googlefuu:

 

EW10J4S from the 206 190, 307 Feline, 307 CC180, C4 VTS.

 

152 lb-ft @ 4,750rpm,177 bhp @ 7000, 1997 cc.

 

 

Clio 197 and 200 are 159 lbft @ 5500.

 

 

 

F20C (honda S2000 engine) 153 lbft @ 7500

 

K20A2 in Euro Civic type R's makes 142 lbft at 5600.

 

 

 

Many many years before there was the S14B20 in italian 320IS's, 155 lbft @ 4900.

[GeorgeXS 32]

e90 bmw 320i and 320 si are 155lbft

 

toyota 3s-ge is 159lbft in its 5th generation.
