Low End Power

[Silver_06_S2k]

Im trying to decide for the future, when my warranty is all said and done and the cars paid for, what I want to do to the car. I want some more low end power already, although I love driving it and top end power would be icing on the cake. I'm reading that supercharging or turbocharging isnt getting the low end push (I was aware that turbos would do it, but I figured an SC would give a boost in the whole band). What are guys doing to push the low end?

LS1 swap?


Haha...but more reasonably speaking, you're never going to have any significant low end power with the F20. You could do a lot better than what you have now by increasing the displacement and going with individual throttle bodies. Your low and mid range power would be increased pretty well, but it still won't be anything spectacular. This setup will also be very costly, and very time-consuming to tune properly for regular street use.

I agree with Scott. There is no way to get a bunch of low end torque (power) with the S2000. Forced induction (either way you go), will help out but as stated, its not going to be all that great.

'Sorry Sil, but Scott n' Spa r' right on the mark. It's an often spoken about topic n' the end result is always the same. Nothin' short'a JATO's gonna give li'l Stewie anythin' of consequence downstairs.
Inline's got some very impressive large-bore, long-stroke versions of our engines which will, no doubt, take care'a the problem, but it's a major hit in the wallet.
The easiest n' most efficient way to boost power (accordin' to our more technical brethren on site) is (n' I'm sure I'll be corrected if I'm gettin' this wrong) 1)Turbo n' 2)Supercharger. It still doesn't give you much more downstairs, but the boost upstairs might make you care about that a little less.
Be well.

Get you a good set of gears. It will help alittle.

[gomarlins3]

Gears give you the feeling of low end power.

[bobby2002S2K]

Yea, true. but the power gets put to the ground. You changed your gears didnt ya gomarlins? Did it make a bit of a differance?

[Java Junky]

I realize that it's not a solution to Stewie's lack'a low-end, but if it's possible, havin' somethin' like a mechanically-sound, but inexpensive ol' Mustang r' somethin' similar to satisfy those urges to smoke-em'-if-ya-goddem could take care of our personal need for low end. (For P.R. purposes it gets listed as a "parts chaser/parkin' lot car, I won't tell) But with somethin' like that sittin' in the wings to satisfy the urge when it surfaces, it makes the jumpin' inta Stewie alot more appreciative of it's very different abilities.
Face it fellas, when we spend time with something, anything, we have a tendency to get bored with it n' wanna make it more interestin'. While Mama Java wouldn't be at all understandin' of my havin' a lady on the side, she n' Stewie ain't got that problem with my keepin' the family "beater".
N' it even allows that you guys with newer Stewies can stay relatively stock n' under warranty.

My .o2:
Changing gears only gives you the FEELING of more power, and only in relation to the same NOMINAL stock gear ratio. . .

In other words, third gear with your new final drive will put more torque on the ground than third did stock.

The problem with changing gear ratios is that it only helps your performance if you do it with a specific goal in mind . . . you may not have enough power to pull a certain hill in fourth, but more than enough in third, so you drop your ratio slightly, and now have just enough in forth! Presto! Better times climbing THAT PARTICULAR hill. I have four different rear sprockets for my Raptor just for the purpose of drag racing up different sand hills and can tell you IT MAKES ALL THE DIFFERENCE!

It may be that a gear change gives you faster 0-60 times (depends largely on driving style) or faster laps on a certain circuit, but it doesn't give you more power, it just moves your ratios closer (or farther apart). In my opinion, it's not worth mesing up your free-way cruising, but that's MY situation. . . yours may be different!

I think GO has a shorter final drive, and I bet he has a reason for it. Maybe he just likes how it feels. . .

Anyway, that's my rant . . .

[s2000isu]

Ok well if it gives you faster 0-60 and faster lap times whats the problem with gears? Afterall tq is just a number im concerned with how the car performs not with what numbers the dyno says.

Yes, I have 4.77's. I wanted to get into VTEC quicker since a SC doesn't really start to help until VTEC. It's not my DD so cruising RPMs and MPG were not a concern for me. If those things matter to you, gears are not the best way to go. I take two long trips a year in the S, other than that it's just a weekend toy.

Gears MIGHT give you faster times . . . it depends on the situation. My point is that changing gear ratios is usually done with a very specific goal in mind.

[ShadowX]

Depends on how low you're talking... A turbo will give you gobs of torque pretty low in the band, especially for a high rev'ing motor. If you just want to stay NA, getting a large increase in low end torque is going to require some major modifications.

So the easy answer is boost.

[bobby2002S2K]

I really think if you want bottom end your going to have to give up alittle on top end. Such as using gears. I know its not adding power to the motor persay. But you appling what you got to suit you. Gears is the cheapest way to go i think to get the performance on the ground at low end. My personal feelings is i dont care about doing 150 or 160 what ever my s2k tops out at 130 to 140 is fine by me.

I have an 05 Mustang, so it scratches my itch when I need some torque. But there is certainly no feeling like this car, thats for sure. Thanks for all of the great answers. So I guess the real question then is supercharger or turbo?

[ShadowX]

If torque is what you want, a turbo is where you're going to want to go. There will be some lag, but that all depends on your setup. The stock turbo on my FC barely had any lag, and the lag on a Skyline GTRs is pretty much nonexistent with the twins.

Yeha I think i've made the decision for turbo, I think its gonna serve me the best. But I've heard they are harder on the engine than SCs. Is this true guys, plus its more involved in tuning, anyone know of any good wrench turners in cali?

[gomarlins3]

I believe Shawn Church is in So Cal. He is one of the best.

[Silver_06_S2k]

Hey Go, does he have a website, any contact info?

[gomarlins3]

I believe this is the same people:
Church Automotive Testing

I have never dealt with them personally, but have heard many good things about them.

More power(torque) is definitely going to be more stress on the engine, so in that respect, turbos will put more wear on the motor. Otherwise, when properly tuned, I can't imagine how a turbo would be more stressful than supercharger. And actually, since a SC run off the crank, I'd think that would stress the motor by putting physical strain on inteernal components, beyond the stress added by increased power.

[DMC_S2000]

if you want low end torque you should basically go to supercharger

[Java Junky]

If you want low-end torque . . . you're lookin' at the world through the wrong windshield.
