I was reading the discussion on the Supraforums of the WRX vs. S2000 and people kept saying the F20c is tapped out in performance in N/A form. From the talk on this forum it seems like at least 300 HP can be made. If this is true then has anyone actually built a F20c that makes 300 HP N/A? If so then what parts were used?

A point my friend made was that if it could make 300 HP N/A then where are the parts? The WRX has been out since may and there are people running 12s already. Granted the WRX has a turbo but the point is still there.

Well - Let's see. The Mugen S2200 is almost a $9000 engine exchange reality yielding approximately 275 hp from bottom end engine work.
There are cams, valves and valve springs available from Spoon but I'm not sure what that head-work will generate. Most N/A enthusiasts are waiting to see what Toda releases and those parts are overdue.
300 N/A HP is by no means out of the question and the parts are just becoming available. It will be expensive but it will yield power through the mid and upper power bands.
Even though I plan on getting every N/A HP available if the parts were out today I wouldn't buy them until putting at least 50K - 60K on the stock parts.

 

Let's get something straight about the WRX. Yes it is turbo and much easier to make power and it's not new. It's been around for awhile overseas whereas the F20C has not. A lot of the parts for the 2.5RS are interchangable as well. So before we go jumping to conclusions let's check the facts. How many 4 cylinder NA cars do you see making 300hp period. So the point is not there.

 

That is what i thought. But i was lead to believe that the WRX engine underwent serious changes to meet emisions requirements and it wasnt the same engine. So your saying its basically the same as the WRX engines overseas?

Actually the point was that the WRX has been stateside less than a year and it has lots of support and they are running decent 1/4 mile times. Of course if the engine is the same as the ones used overseas then they DO have quite a bit more time put into R&D for that engine. But i was lead to believe the engine wasnt the same... Of course my point isnt valid if they are basically the same engines

Why would anyone buy an S2000, one of the best handling

Current WRX engine is merely an evolution of past WRX engines. All performance parts, turbos, IC's, ECU's, bolt on with minor modifications.

There is an esteemed member of this board (read - he knows his s--t) that is currently working on developing the F20C head. It looks like there is some good potential in the head for more hp. The work is just underway, and I can't disclose details, but it looks like it may be possible to get 300hp from a 2.0l F20C on pump gas if the whole package comes together properly.

More parts are needed, like the Toda cams, and a method of tuning the fuel delivery system, but the ball is rolling.

I think that everyone will be very pleased with the NA gains available.

I'm really looking forward to seeing what hits the market in the next 12 months - definitely some great stuff in the pipeline.
