Hi everyone! I have not been on the forum for a long time, but I own a special 2005 Rio Pearl S2000 and am the original owner. It was awesome stock, but I have made a significant performance improvements to it. It has a Comptech supercharger kit with aftercooler, but I did not stop there. I had Science of Speed in Pheonix put a "Stage 2" kit on it, which included a smaller pulley, new head gasket, injectors, and AEM EMS and then had it tuned and it makes 370 whp and 240 tq (you can see my dyno chart at SOS website) http://www.scienceofspeed.com/
It also has the Comptech headers and cat back exhaust. Its pretty awesome. My question is:

How can I further improve the performance? I am looking to take it to Corvette Z06 territory. Thanks everyone!

 

1. Sell S2K
2. Buy Z06
3. ?????
4. Profit

 

8 cylinders > 4 cylinders

hope you upgraded suspension as well to keep the power on the ground.

 

Stock or modded z06? C5 or C6? I'm thinking if you wanted to compete on that level you should have gone turbo. You can only push that supercharger so far.

 

Turbo, check you tube, i've seen some 550-600hp s2000s running against vettes.

 

yeah, ditch the super charger and go turbo. you can get there with the supercharger but you wont have the broad power band that you need to race vettes and stuff.

 

Well u can start buy getting a larger exhaust 75+mm single and a matching test pipe. Berk has one. You could also bore out the engine to 2.4 or 2.7 liters. New intake manifold. I'm guessing u already have lager injectors. You could also run lower gearing if u ever make over 500 whp. Custom headers with larger piping. When it is all said and done this could give you enough to race a z06 and cost over 7k. Or you could go turbo and be slightly easier.

 

Thanks all!! I think I will contact Tony Pollo at T1 and see what he can suggest. Ireally like the superchargers power band. Boring out is interesting..

 

yeh def. turbo it man. rebuild the motor and put 9:1 pistons, sleeve and push 25+psi out of the turbo lol. that should do the trick and if it don't, well you know how the saying goes. someone will ALWAYS be faster.

 

Well c5 z06 territory is not far away as they are slower than C6 corvettes now. Believe you should be close with them now. Having that head gasket is hurting you but if you do decide to go turbo could be useful later on.
