FrenchS2000

Hello everybody

I prepare to modify my S2000.

But I hesitate between Supercharger (with Aftercooler) and a 2.3 Stroker kit.

In France, we go more quickly on the road in general : 100 mph minimum on motorway

So many people disadvised to me installing a Supercharger (i prefer Vortech) because mechanics suffers too much.

What do you advise me? Stroker kit 2.3 or Supercharger.

Thanks for all

The problem is that if you add a super or torbocharger, then you will need, beefier brakes, LSD...etc. In the end you might be better off bying a whole higher performance car.
My advice: Ne fait rien, et va plutot t'amuser dans les petites routes de campagne (Don't bother, and have fun in all these little backcountry roads)!
If you still want to modify it, then rather go for the stroker kit, or even the gear ratio kit; and also, even if it doesn't make such a difference, a CAI is a nice, easy mod to have.

Merci de me parler en fran

Limited Slip Differential -- the car already has one of those, but he is saying that if you put too much additional power through the driveline you will exceed the capacity of the components.

One thing to consider for high speed purposes is heat soak. If you want to drive for hours and hours with the extra heat produced by a supercharger, you might have to consider extra oil cooling capacity.

How's this:

Unrelated to your question but have you had the European recall done for the upgraded oiljet bolts?

Under typical N. American conditions, this would not be an issue. Many supercharged cars have been running daily on these roads for many years without any problem. However, if you typically drive at extreme high speeds on a continuous basis, any of the known supercharger kits may not have known outcomes. Cruising at 100+ mph would put your engine above 5500 rpm. This is well into the significant boost stage of these blowers. Not sure what that would do for extended running. Over here, forays into 100+ mph are only for brief moments at a time.
A stroker kit might be an interesting option, although you would then be looking at elevated piston speeds. Honda dropped the redline on the 2.2L engines for this reason. This would have to be a concern if you go this route.

I'm not feeling the total validity of this statement. The stock car's components are designed to handle it's current performance envelope up to its top speed of 150 mph. Putting on a supercharger would only stress those components if the owner chose to go faster than this, which the S/C would more than likely make possible. If you already drive 100+ mph, do you plan to drive above 150 mph once you put on a S/C? If not, your brakes, etc, will be fine. Being able to accelerate more quickly doesn't mean you need better brakes. If you stop from 100 mph, you use the same brakes regardless of fast you got there. On the other hand, repeated use of boost to get up to speed may put additional loads onto things like tranny, rear diff, CVs, especially if you do so up to high speed on a regular basis.

The OP didn't really say what he wants the car to do. Do you want to get up to speed quicker? Do you want to drive much, much faster? Do you want the capability to increase your speed quicker? Do you want to maintain the same kinds of speeds you currently do now, but with more ease? Depending upon what you are trying to do, you might want to consider going numerically LOWER final drive gears AND put on a S/C. Until you state what your purpose is, this last option cannot be ranked with any accuracy.

Lots of us track our cars on stock brakes...I'm supercharged and I do...

Eluded

are the roads in france capable of 100MPH speeds?

Also what do you think of this :

I can't quite get past they think a 2.45L, 4 cylinder engine is a "big block monster".

BTW, either of the existing stock supercharger kits will give you way more gains and for much less trouble.

I'd be worried after looking over their website. 800hp crank 45 psi but the only dyno they show is 304whp.



Are European f20c's the same spec as jdm with an 11.25 compression ratio rather than the 11 to 1 compression ratio we have here?

That and fuel availability may affect an US designed SC kit. I don't the answer to that but it would make me lean toward an AEM system so I could tune it to fit my environment.
