4.77's and sc chiming in centrifugal sc's keep the powerband completely linear and boost response instant when downshifting. gears help with the low end and get the car into boost much quicker.

i have no problems on the freeway... 4500rpm ~75mph.

 

Thanks guys. I knew a statement like that would provide good feedback... Great feedback actually.

Here are the points i'm coming away with...
1. Yes, the s2000 is very light so not as much torque is needed in the 1st place.

2. The Comptech and Vortech both have minor torque improvement.

3. With 4.56 or 4.77 gear ratio it make it easier to keep the S in the power band.

4. No tunning needed so performance is guaranteed.

5. My s2k is RHD so turbo will be very expensive project.

Here's what I'm planning based on comments:

- Spoon S2000 4-2-1 Exhaust Manifold (to prepare for SC)
- Spoon S2000 Head Gasket (bit more torque)
- Spoon S2000 Fuel Injectors (bit more torque)
- Toda S2000 Individual Throttle Bodies (a bit more torque and all around improved response)
- 4.77 gears.
- Comptech SC

I want to improve the power band 1st then SC it.

 

Raising your compression with a Spoon headgasket is not a good thing if you are going boost.

The spoon headers are not ment for a supercharger, very restrictive with small diameter tubing.

Spoon fuel injectors will be way overpriced and too small.

The Toda individual throttle bodies will make supercharging a nightmare and require an aftermarket ems like AEM EMS.

If you are making any extra power the 4.77s will be too low.

You need to read up on this stuff. Failure to study up will cause a very large dissapointment to be heading your way with a giant price tag.

 

thanks Sideways

that's why posting 1st. Thanks.

S/C+4.77s!!!

gomarlins3 also said: That's what I have.

What's the best HP output with NA tunning?

So you are saying 4.77 + SC isn't good?

 

2. Going from 120wtq to 180wtq is big for the s2k.

4. You need to tune the FMU to be safe.

5. Turbo can be done for around the same price as a SC.

 

N/A Tuning the s2k is $$$$$

 

4.77+S/C is optimal for stock boost, it's just extremely aggresive. When you start upgrading the S/C (head gasket, fuel injectors, EMS, smaller pulley, etc.) you may start to have traction issues, and it may become too aggresive. I already have a hard time hooking up in 1st 25% of the time.

More boost than stock=4.56+S/C.

Hey, I didn't say it was safe, I just said it's the fastest Nitrous is some serious power, but it can be dangerous especially with our high compression. If you wanted to go nuts, you could drop the compression and do some highly tuned nitrous setup. It would be very fast

However, a 50 wet shot on our compression is going to be pretty safe. Just make sure you don't spray below 3k (rod bending time!) and you should be alright. I was very close to doing nitrous but I decided to sell the extensive NA mods I had and just get a turbo kit.

 

I stumbled upon this thread and was wondering how there is boost at idle?
