A friend of mine speaks Japanese and translated the page for me. It's not a word-for-word translation, but here's what he said:

---------------

These days, people (at least in Japan) are selecting a smaller volume turbo system with a low turbo pressure to go with an unmodified engine (no compression change). That way, it provides quick responses and generally works well. This Power House Amuse, however, thought a larger volume turbo would work better with S 2000 mainly due to the engine characteristics (high rpm, cam profile, ignition timing, etc.). They thought a smaller volume turbo would only increase the mid range, but the top end would not see much improvement.

So, they tried GT2530 turbo (low volume) just to see how it goes. This one is shown as the blue line on Dyno. As you can see, it increased the mid range, but the top end didn't increase as much as they hoped. The big drop is where the VTEC switches and they think the drop is due to the lack of turbo capacity (low volume). The red line is TD06-20G which is a larger volume turbo. The turbo boost pressure they set up is around 0.4 kg/cm2, which I think is around 5.7 - 5.8 PSI. Seems like it works very well. According to them, this turbo has enough volume to be equipped with 450 hp class engines.

Just adding this kit (without changing the compression), this S 2000 produces around 280 hp. When they changed the ignition timing all the way to the limit, it produced around 310 hp, but they don't suggest to set it up this way. The kit does not include the inter-cooler, by the way. Also, they mention this additional computer to control ignition timing, fuel flow, etc. but they don't say if this is something included in the kit. Also, to make space for the turbo, they needed to move the ABS controller a little bit.

Seems like this shop thought that if someone is spending this much money to modify S 2000, they probably would like more horsepower at the top end, instead of increasing the mid range. (I agree, you have to rev up S 2000 to enjoy) So they mainly focused on top end, but since the engine itself is not modified, the low & mid range pretty much stayed the same way. They don't say much about modifying the engine, but seems like they are focusing on a kit that works well with unmodified engines.

Since the kit does NOT include the intercooler, and my gut feeling would be probably not include an ECU either, I would guess that the final cost for this kit would be the $6-7000 range...

 

It looks like they're using the Hi TEC-ROM from Amuse (148,000 Yen~$1235). That's assuming the cost isn't included in the total cost.
True, but it looks like they're using the Amuse CF hood, with ventilation directly where the intercooler is. I'm sure that helps.

[B]and I don't see the battery in the picture either (must be re-located).

 

Will this kit even work in a left hand drive car?

 

I knew they would go with the GT series HKS turbos (full bearing cartrige) - too bad they used the puiny version 25

 

Looks like the base line stock Japanese S2000 makes 226 ps or 223 HP at the rear wheels. I'd like some of that.

 

Damn it

I am gonna write the rest of this in upper case ok..

YOU CANNOT COMPARE THOSE DYNO RESULTS WITH YOUR DYNOJETS!!!

Amuse (I am quite certain) now uses Dynopaks, which attach directly to the wheel hub. Look at percentage changes, not nominal power - It is not comparable.

220hp at the wheels is not 220hp at the wheels on a dynojet!!!!!!!!!!!!!!!!!!!!!!!

 

On a side note, we're trying a coupld of different things with my setup but the dyno had a problem so we're waiting on a new part. However, we have temporarily replaced the tubular manifold with a log style (should cut final cost quite a bit) and with the log style and 4 PSI the car made around 260 RWHP. IT should be a little higher but when we dynoed the dyno kept warining us that the air temp was above 110 F. I'll keep you guys posted.

 

Just wait

 

In the July issue of Options mag on page 123, there's also a side picture of the same turbo I think.

 

i have several magazines with this car in it, and it's supposed to be a bolt on kit, the intercooler is mounted upward in front of the engine, below a a hood scoop, the kit uses trust and amuse parts, but does anyone know who fabricated the kit?
