Just my thought.

Now Im no expert, however:

The thing is that the car is a 2 liter high compression motor making 200bhp which equals 100hp per liter. To the wheels, the car makes ~160 depending on location, elevation etc etc. A FULL exhaust from the header back I have seen gain almost 20whp with a tune. An intake/filter will get you another 3-5 maybe.

That being said, just with bolt ons and a tune, you're looking about 180-190whp. That's the equivalent of how much at the crank? Around 230bhp? That's 215hp per liter which is almost as much as the F20C motor in the S2000. That's pretty impressive in my opinion. By working the internals a bit, I'm sure you could squeeze out another 10 or so whp but I'm not sure.

E85 tune is honestly the best bet. I've seen dyno results where people a making 200whp+ just on intake, catback and E85 tune.

With the NA build that will be money and I personally don't see the point in doing that if you are going FI in the future. I feel you would be better off with just the simple bolt-ons and a tune. After that suspension work and lighten the car a bit.

Consider this fact:
A friend of mine tracks this car and he stayed NA. He blew his motor. Now from what I have heard these boxer engines aren't too reliable (but I guess that depends on driving habits).

Now the goals are probably achievable but IF it is your only car I wouldn't rag on it so much. Good luck with your build though and if you are trying to get good power and you know you are going FI in the future, wait it out. Bolt-ons and a tune and be happy

Yeah these motors are pretty stout. Either driver error or shit tuning in my opinion.

Boxers in general or just the FA20? And honestly that is the first person I really heard who blew a stock motor beyond the issues that were common to the early release cars.

Now of the 2 people I know personally who went turbo, one blew his motor and the other is still having oil issues 4 months later (still R&D stage I guess as I don't think that specific tuner/shop is selling their own kit yet).

Ya i wanna see a good na build, not everyone wants turbo...

The problem with NA power on this car is that the compression ratio is already pretty high and we're only getting 200hp at the crank.

Ehh it can be a number of factors. I personally think it might have been driver related but idk. In my experience I have always heard of problems and I know specific tuners like to stay away from those motors. I just know what I want out of this car



I am sure these blocks are fine but it just leaves one to wonder how much abuse they can stand up to because everybody has different driving habits

I just want a bit more power and keep the response with no turbo lag, for a dd i dont want turbo cause i know i have bad self control and i be wasting a ton more gas. If i retire my car from dd duties i wouldnt mind turbo cause i be driving it less but that wont be for years.
And of course its way harder to make power in NA thats why i wanna see a good build, na builds usually cost way more and you dont even come close to FI power with the same money put in.

For a DD I would recommend a supercharger. But when I take my car out for a drive it's pretty easy to drive. From NC to MD I got an average of 27 mpg. Around town with me getting on it pretty good from time to time I get 24-25mpg. And turbo lag on this set up basically none. Seriously.

But as @forzajuve just posted, look at the money to hp ratio.

Lol your getting way better mpg then me with turbo compared to my few bolt ons, but here in canada we have shit gas best i can get is 91 no ethanol, but good to know that the turbo doesnt lag much. What kit are you using?

So I was curious as to what kind of set up you are running if you don't mind me asking. The car is impressive and feedback on the FI setup that you have would be interesting to know. PSI levels, still stock internals, etc.

Any info would be good. :w00t:
