it's between 8-9sc for stock RS version. The video that I posted says it has re-flashed ECU.
*
The driver in the video drove in D gear. I have seen review from china saying in order to optimize the 0-100, he put in L gear to reduce turbo lag and managed 7.0s - 7.5s. I also read that one of the advantage of the honda 1.5T is their max torque extend all the way up to 5500rpm, comparing to e.g. VW 1.4TSI, max torque 250nm but start dropping after 4500rpm. Don't forget honda 1.5T has quite high HP also, 174hp. So, don't underestimate the engine hmm.gif

Then how about this official figure from Honda China...cropped from Paultan. Conflicting right...they tune higher to make US customer happier is it.  sweat.gif

"Only one engine is available for the Chinese-market Civic for now – the 1.5 litre VTEC Turbo unit which produces 174 hp from 6,000 rpm and 220 Nm from 1,700 rpm to 5,000 rpm and will go from 0-100 km/h in 8.6 seconds. As for transmissions, the Civic can be specified with a six-speed manual gearbox (the first market to pair a row-your-own transmission to the turbo mill) or a CVT."

This is the so called "official" spec from Honda. I have seen various China reviewers showing they can easily achieve <7.5s century sprint (autohome tested 7.09s). Anyway, even 8.6s is still faster than FB 2.0.

Bro, im sure ure aware that even the Koreans have a turbo in the market and it's not a soft turbo like the Civic. And their cars aren't priced over the top either. Anyway u can still have the soft turbo but pair it to a normal torque converter transmission and u'll get much better acceleration figures. You don't actually need a twin scroll turbo.

Is the Civic the most powerful in its class? I thought the Jetta is more 'powerful' with its 250Nm torque from 1,500RPM vs the Civic's 220Nm from 1,700RPM?
*
Since when torque is the only number to determine power?

The new civic has better horsepower figure and has longer sustainable torque curve, up to 5500 rpm, Jetta TSI starts to roll off after ~4000 ish.

Not sure which is true though, if we examine the Hondata torque curve, the data suggest that it hits past 200nm by around 2000RPM and builds till 4750RPM before slowly tapering off.
The Injen chart is more linear with lower figures, torque peaks again at around 4700+RPM  before tapering off.

The Jetta on the other hand peaks just slightly over 2000RPM and sustains its torque until around 5300RPM where it begins to drop under 200nm.

Can't wait to get my hands on an actual Malaysian Civic then sending it to the dyno to see how it actually compares.
*
Hmm, I have seen other dyno result stating Honda under-rated the HP and torque. Very contradicting result it seems.
Motor Trend

But then new Civic is running with CVT, so I don't one can compensate the gear ratio on a dyno, unlike MT or AT with known gear ratio. Well, I am not expert tongue.gif

Anyway, agree with you that we should stop speculating. Too many keyboard warriors nowadays, should only comment after test driving. blush.gif

No one seems to concern on the new Earth dream
DI engine. Not sure if carbon build up will be an issue or not?

They overcome this issue with a combo of port and direct injectors.

Low RPM - port, high RPM - Direct

Something like that if I recall, solves the carbon issue.
*
I thought this is implemented in Toyota d4s engine (new car 2.0), so the new honda 1.5t uses the same method?

DI carbon build up actually adversely impacts normally aspirated engines more than turbo DI ones.  Good article on why here:

Nice sharing. So the conclusion is by using high quality engine oil, the carbon deposit can be greatly reduced?

Notice something strange on Honda Malaysia website. Notice under specification, the 1.5t is written as programmable fuel injection rather than DI?

I think some people here should get over the VTEC stuff.... Ever since Honda lauched the R series engine, the real VTEC (eg: the B16A series with cam lobe to switch between low and high cam) was gone. It's all about fuel efficiency, low end torque and tight emission control now. It's no longer the 8500 rpm redline rev friendly, high pitch sounding engine. Usually the engine designer has certain specification to meet (HP, torque, emission) and it is up to them to employ the most efficient way to meet the spec and if the spec is met, why put in more stuff to make the engine more complex?

As far as I know:
1.0 VTEC turbo: DOHC DUAL VTC + INTAKE VTEC
1.5 VTEC turbo: DOHC DUAL VTC
2.0 VTEC turbo: DOHC DUAL VTC + EXHAUST VTEC

As long as the HP and torque figure stays the same as in US / other market, it means Honda did not detune the engine for Malaysia.

The 2.0L not using high lift cam for both intake/exhaust ?

I assume it's the new Type-R 2.0L turbo engine right. Then the VTEC high cam should be for both intake/exhaust.

http://world.honda.com/CIVIC/video/VTEC-TURBO/

Too bad from the video link above I only can see one of the camshaft... and it's the exhaust cam from the configuration. So I can only assume the intake cam also have the high lift cam
*
I read it here http://hondanews.eu/eu/en/cars/media/press...da-civic-type-r

"VTEC varies the degree of exhaust valve lift to reduce turbo lag through increased exhaust pressure at lower rpm while delivering a high output at higher rpm"

16.5psi boost and still run 0w-20 oil? I wonder if oil burn issues gonna happen

A stock GTI doesn't even boost that much
*
16.5 psi is only 1.14 bar which a lot of people here consider as soft turbo. I am pretty sure Vw 1.4tsi is pushing more than that. If not mistaken, somewhere 2 bar.

so the GTI is a "softer turbo"? doh.gif

and no, the 1.4TSI isn't pushing to 2bar doh.gif
A stage 2 APR maybe, which is already the 300hp mark. Don't mislead the public please.

I won't say somehting without stuff to back me up. I am not familiar with VW engine, but I read in this article
http://www.motoring.com.au/volkswagen-golf...incharger-2023/

Quote from article : "Boosting intake pressure by up to 1.8 bar (26.5psi) in low-speed/high-load conditions, the supercharger is behind the engine’s formidable low-end grunt. At 3000 to 3500 engine rpm, the supercharger drive’s clutch disconnects and the by-pass intake tract diverts to the turbo which is by then on the pace for a seamless takeover of pressurising the ingoing air by up to 2.5 bar (over 36psi)."

I assume one of the reason 1.4TSI can take more pressure is due to iron casted engine block. We shouldn't compare GTI here as it has 2000cc displacement.

Seriously, what is the point if you drive a sedan vehicle with so many HP or psi? On the road, safety comes first and not speed. Or else speeding ticket will awaits you along the way + put other road users lives in your hand.

blink.gif blink.gif Dude, maybe you should laern to follow the discussion and not making some completely out of place comment. I am discussing with dtna7 which he thinks this honda 1.5 turbo engine is boosting high pressure and may risk burning engine oil, i pointed out 16.5psi is not very high in relation to for example the famed VW 1.4TSI. As simple as that.
