NA build
hi there again, how would i go about buildin a f20c, as a naturally aspirated engine, and i wanna go all the way. what would be the best tings to change, and parts 2 use?
btw, what would be the estimated hp and torque numbas would be likeq

What do you have in mind? Do you plan on using the stock crank? Rods??? Since the F20C is already pretty much maxxed out as far as power, you'll have to spend mega-bucks to get more. And, reliability becomes an issue. The concensus IS that you can get about 20 more horsepower 'reliabily' by spending about $5000. Now if you want to go wild and money is not object, start by contacting shops such as Falicon Cranks and Replika Machinen for crank and head work. You can also check into the latest fad such as cryogenics. How much do you want to spend?

lets say that money is no option here...... and i don't tink that i would be using the stock rods. de car is goin to be a daily driver and weekend/street racer. i lookin to get de best throttle response, and as close as possible performance to the Spoon S2K

The intake on the F20C is already very efficient. And then you go on to say that an ECU adds another 50HP. Flush that crack down the toilet, OK? Unbelievable!!!
Lamphant, spend 30 minutes with the "search" function and you'll get all the info you need. With that being said:
If you have the 10 large (+) lying around needed to make any sort of reasonable power increase out of this motor N/A, it's money better spent in either FI, or trade-in money along with your car.
This motor makes precious little power over stock in stock displacement. There are stroker motors out there making more power (no replacement for displacement), but they're almost as plagued with gremlins as turbo motors are (currently) and cost about the same to build. The S/C cars seem to do nicely without a huge decrease in reliability ('stock' pulley).
Ultimately, the S2000s' limit seems to be just under 400 HP before things start breaking and the car becomes a terminal money hole.

search is not working at the moment, which is why he couldn't search anyways.
removing the stock ECU is the key to start making NA power. I have seen dyno's around the 250-260whp range with intake/test pipe/header/exhaust/ECU.
beyond that you're talking about building the engine and increasing the displacement or increasing the compression. this engine does have plenty of n/a potential, but it all depends on how much you want to spend.
