AHA! Sideways my friend, you have now just made my choice between the STi and s2000 extremely difficult.

What exactly is his list of mods? Any links to his setup etc?

 

You need an STI.

 

Actually that dyno graph looks pretty awesome on that s2k, so now i am really wondering what to do. I am tryin to search and find out the parts he has in his car...

 

top fuel turbo kit with hks gt25 (go to speedoptions.com and check out the featured ride for more info).

If you want great tq with insane acceleration, a smaller hks branded turbo is the way to go- just like webestore's setup.

If you want great tq for everyday driving and have the tq curve flat all the way to redline, wait for the BRP s/c, it looks promising.

 

Okay, thanks a lot for the info.

Thanks everyone who chimed in to answer my question in this thread. This is a great forum, and i have been lurking for quite some time

 

The torque of the engine is one thing, the torque on the wheel is another.
The torque on the wheel depends on the engine torque AND the gear ratios (the greater engine torque and the greater gear ratios increase it)

The punch at 70mph in 6th between a similar hp S2000 and STI will propably be the same because the STI may have greater engine torque but also has smaller gear ratios (it has to because it doesn't rev up to 9000rpm).

These are things quite difficult for a newby to understand but here is a hint. Measure the hp (not tq) number at 50% of max rpm (or 60%) of the cars you are interested in. The car with the greater hp number will have the greater torque (in the sense that at a given gear and speed it will accelerate faster)

The diagram Sideways offered is, i believe, of a car with a small turbo. It has only one minus, that power drops significuntly at high rpms. If this doesn't bother you then it is definetly the way for you to go (it is the best turbo in all other respects). If this does bother you and you want not huge torque at middle rpm (and absense of it elsewere) but linear pwer delivery at all rpm you shoyld think of the BRP supercharger which is curently a prototype.

If you reduce the rpms of the engine you will reduce horsepower surely but for torque youcould be the same, a little higher, but most likely lower. The only answer for you here is displacement. Put in a 2.5L stroker kit which should mean a lower redline. If you then need 300 ft/lbs of torque you could do so with a turbo/supercharger and make only 400 horsepower (just a scientific wild ass guess) to do it.

Anyway, I don't see the obsession with torque. The idea of torque in a car is misunderstood. Everyone thinks of it as low end power. That is not really true although it can be a good indicator. Horsepower is the the amount of work being done, it takes work to move your car. Horsepower is a dynamic measurement. It is what makes you go fast. Torque is a potential to create horsepower. It is a static measurement. It only looks at a single point in time. The reason "torqueier" cars feel the way they do is because they make more power at lower rpms than smaller engined, high rpm cars that excel at the higher rpms.

 

Get a Lovefab kit with a GT28 or smaller. It'll strangle your top end but give you great torque down low.

That said, the stock block with LoveFab GT3071 is awesome.

 

Ok i am beginning to understand, however when you say "torquier cars" feel torquier, well then you are saying what i cannot articulate, or i am using wrong terminology. What i want from the s2000 is more low and mid range power. I understand this car was designed as a track car, but I will be driving it in the city. I want the low end power of a v8. Whether or not this is torque is up to you guys to decide i guess, but i want that power down low, whatever it is called.

The BRP supercharger looks great as far as that flat torque curve goes... having all of that usable power at all rpms is really enticing. I would really love a shoot-out between that and the Lovefab kit or Inline Pro kit to see which one was actually faster.

Thanks again for the replies, I have learned a lot.
