TOV 2006 TSX review

article here

Whilst the differences between the Euro and the TSX are now greater than ever - there are so many interesting points in this article it is a must read.

This paragraph is very interesting:

At the 2003 US media launch for the TSX, Mr. Sakuji Arai (the chief powertrain engineer for Honda 4-cylinder motors whose credits include the F20C and K20A masterpieces) was quite visibly proud of the TSX's K24A2. In fact, he asserted that the K24A2 was Honda's finest 4-cylinder ever - a claim which makes you think a little bit about what the engineering goals were.

You will also find some of the comments to ring true with the Euro (the issue of rotor warping is raised - TOV says it is not the rotors causing the problem - it is the pads). Also the people with hard starting problems (I am not one of them) - clear vindication that you are not hallucinating. :D Comments about lag in the DBW - all there.

Excellent article and credit to TOV for such a great piece of work.

So what do you guys think about the article?

Thats a good read :thumbsup:

Does that mean that the Aussie 06 Euro's (K24A3) have more power too?
somehow I doubt it :(


Come to think of it, my Euro takes 5 or 6 turns to get the engine running, where my Civic only took 2 to 4. Here's hoping it doesnt have that hard starting prob...

Answer is no - we carried over the same power specs from 03-05 models.

ps. the Axxis Ultimates given a huge thumbs up by TOV are actually made in Australia by Bendix. They are the same as Bendix Ultimates. Think these are going to be the new pads on my euro.

We get the K24A3 from the Accord 4WD Wagon. 03-05 in the US got the K24A2 from the Accord FWD Sedan. For 06, I think they got a US-specific engine as it has large intake valve openings as well as a larger throttle body.

that makes a little more sense, because i was spun out a little by the fact that they had the 6MT cracking into the high 6 seconds for 0-100 km/h. Even still... could the claimed 10hp off make the TSX go that much quicker, considering hondas stats read somewhere round the 7.8-7.9 mark? It may be a combination of all of the little things they've fixed.

I think their TSX is heavier than our Euro, so the original K24A2 performed close to the Euro's 7.8sec. But the extra 10hp getting it into the high 6's? That doesnt sound logical.

K24A3 190ps
K24A2#1 200ps
K24A2#2 210ps

7.5 sounds more logical.

Got to remember, TOV got the 6.9 by flat shifting.

Remember the Corolla Sportivo that was tested by that race driver? It did 8.5s when shifted normally. But when flat shifted, it went down to 7.8-7.9s. Of course, the owner of that car said that the gearbox never felt the same again.

Are you aware of any JDM Honda accords runing the K24A2? I thought the K24A2 is solely for the TSX. The differences to the K24A3 is a bit of an unknown. The most popular view I have read is the engine is essentially the same as the K24A2 but there is a vastly different tune for the US. Then there is the different power measurement standards in the USA (I am a bit lost as to how that works as they keep changing the standards).

Eurodude - you are right about the TSX being heavier. The 06 TSX is 100kg more than the Euro standard in Aus. The 03-05 TSX mostly makes up the weight disadvantage by a shorter final gear ratio and of course the slightly extra power. The 06 has gone forward again in power.

As for the 0-60 times - Car and driver got 7.2 on the 03-05 model. Keep in mind that 0-60mph is not 0-100kph. It is not unrealistic for a mere mortal to get consistent 0-100kph in 7.5 (stock Euro Standard) - so not much difference.

hey thanks for that... i didnt actually know that...i was always under the impression that it was exactly 100kph to 60mph. In actual fact it equals the following:

60mph=96.56kph
62mph=99.78kph

i have the hard starting problem, my service centre think im crazy :(

Guaranteed that the JDM Accord FWD Sedan has 147kW, while the 4WD wagon has 140kW. It's stated on Honda Japan's website. All they give for the engine code is K24A. But you can guess it from the power and torque numbers.
Europe's Accord Sedan also runs the 140kW engine. I have no idea why Honda Australia got the 140kW version instead of 147kW since USA is already havnig that 147kW engine, so it is not an issue of keeping the best for themselves. Remember, USA is pretty much in the same boat as us. Their hottest Civic has a 119kW engine, and they never got the Integra Type R. t least we got the watered down version.
