You can't assume the gains will "stack" that way. The gains from each part will be in different amounts in different RPM ranges. I also think your numbers must be coming from a very high-reading DynaPack (Sean Church?).

 

RSP real street perfomance DYNOJET but i definitely taking in consideration of what yours saying and everyone else... i still may stack parts that combine well all motor to eventually go the supercharger route later on (tax return) ive been such a big all motor fan from my civic days to my current K20A EG (sorry for any grammatical mistakes on my ipad)

 

OEM.

I'm SC'd as well and profit_child, I have no concerns or issues whatsoever with being SC'd and that's the general sentiment with us FI'd guys. Turbo will require a little more effort, but can be reliable as well.

 

You're talking about spending 4500 on itbs and ems. Factor in the tuning expect probably a good 5+ hours to get those dialed in...might be 5k.

You can get a fully built inlinepro f24 (k24 crank) shortblock for a little less or it could be a good amount less if you convert your stock core. You'll be making more torque for sure and should be more driveable than with itbs. 7k will get you a fully built crate f24 that'll be makin 260/190 to the wheels out of the box...add some bc2 or 3 cams and tuning to that and it might be higher

...and THEN put ITBS

 

Lol at monster with just exhaust and a tune. At best your looking at being a little faster than a stock s. Honestly the biggest gain from the header or exhaust is the weight you save. The stock exhaust system weighs a ton. You can easily cut 50 lbs or more by going aftermarket. I have a PLM header beacuse I got a really good deal on it but I am not tuned (05 so not many cost effective options).

 

A little known header, but i found R&D pictures on the internet is the 'Tracysports TS-01' which i had jet hot coated, it made nice gains midrange and up top but lost a little low down - its more of a midrange/high up header.

Honda have gone with an 'overall 4-2-1' header and its very good i do agree from my dyno and tuning sessions. I think there's slightly more scavenging on one of the cylinders.

 

I went to irvine to visit John ,I forget his last name, at Hytech. The dude is awesome! And professionally raced for some formula racing so that's why he builds exhaust systems be/c he finds that's one of the most important things on a sports car! Also, I'd like to make a note, the header is AWESOME! Wayyyy bad ass craftsmanship!!! And surprisingly, it's smaller than the oem! How does J's claim the larger tubing is good; and John says the smaller tubing is great? These headers are way different sizes. Seriously. Also, johns idea is this: the S2000's f20c likes "small". People putting huge ass itb's will not yield power, in fact, you'll retain or lose power. Please don't forget you have to spend the $175 for the short test pipe. I myself was Sooooo close to buying the header/test pipe combo, woulda been $1675 OTD, I put a deposit of $100.00 and some reason, I changed my mind. John still has my deposit as of maybe 2 years ago? I speak with Greg of GT MOTORING all the time and a few times we've had a conversation about the Hytech header. Would I buy one, perhaps yes (now that my car is paid off!! Whoop whoop). I have even spoken to Shawn Church as well, many times, email and phone, and he could only recommend that header if you got the Hytech combination package. Otherwise, I felt he'd prefer not to say his opinion. He said it shows gains, of course like the camshafts, not much, but it's a package deal anyway and I feel that's what John intended. I hope this helps!

I'd also like to make a statement on this Tracy Sports Header. I believe I inquired about the ts-02 header. I spoke with Jonny Grunwald at Bulletproof Automotive some time. The header was $1400 at the time, but I told him if he could get it down to 1200 I was willing to make the drive and pick it up. He said sure, but he'd still have to apply the tax, about $120 extra. I told him no deal, I'd like 1200 OTD. My reason why i didn't get it.. :/
Now for my big reason why I had sooo much interest in it:
The header is beautiful! It's light, and the power is supposively better than a lot of the high end jdm headers. It outperformed mugen, spoon, I believe J's in certain parts, and oem as well. It is claimed to have very usuable power for the racer in mind. The welds inside the tubing where the bracket mounts to the engine make it sealed and leak proof. They are also tapered. Again, why didn't I buy it? B/c I couldn't get it for 1200 OTD.
And 1200 is 4 car payments and hella maintenance, so yeah... The Hytech is more proven as well, but lets be real, 1700 and still owe car payments.. This is the only reason why I didn't make these purchases.
Pm if you have questions.

Since when was Mugen carb legal? are you sure? if so ill buy one LOL!
