need help on upgrading my car, all i have is a CAI, need help to gain more hp. i was going to get a header, but friends said i can loose power or not gain at all.. so give me some advice to modify my car next, and tell me the price. thanks

 

my list of (expensive yet) good power adders:

aem ems & wideband w/ good tuner!!!!!!!
4.77 FD & comptech diff
mugen/j's/comptech/spoon w/new filter intake
T1R exhust w/ test pipe

items to get if u only have the top part of this list:
toda spec a...
port & polish the head

loose some weight is always good too..

 

The s2000 was not designed to win any drag races, but stock it will wax nearly anything at an auto-x. My advice to you is to focus on the suspension. I was hell bent on making power when I first got my S, but realized forwhat you will spend on 15whp, you can have an unbelievably well handling car.

I am running-

PRM Intake
Whiteline STB
Neuspeed X-brace
Espelir Springs

Goodluck.

 

thats true...but if you have the money to spend, adding that power is well worth it

 

Buy an Invidia Exhaust.

He wont be able to feel the power difference.

 

But he will go deaf.

what are you upgrading power for? stop light racing or competition such as timetrials/autox/wheel to wheel? The biggest bang for buck power adder to this car is a supercharger, easiest and cheapest.

dollar to hp ratio - the SC is the only way to go. anything else is just ... nothing. you can spend thousands of dollars mis-tuning this car or you can drop 5K and do it once right.

btw, watch the diff - your upgrade dollars will soon go to replacing the diff.

Although there are people tracking with the SC off the bat, I don't prefer to go that route. I see the SC as a power adder that best suites those that daily drive the car or do stop light racing or are concerned for the hp per dollar invested. I wouldn't go as far as saying that any other route other than the SC is the wrong direction.

 

biggest bang/buck mod in my priority order(N/A):
- lose some freak weight on that thing, get rid of the stock exhaust, cf hood maybe and lighter wheels
- AEM EMS
- 4.77 final drive
- toda or amuse exh header and testpipe
- jenvey ITBs
- Toda A camshafts and thinner headgasket with head milled 15 thous

Good luck
greg

Would you really want to mill the head, even if it's a small amount? Wouldn't the thinner headgasket be a more practical option to help increase the compression slightly? All the other mods you listed sound tasty. I was checking out header and exhaust systems for the S2k on http://www.bulletproofautomotive.com That **** is bling..
