that doesn't sound right at all, if it is that's awful!!!
based on number I won't be able to live with this car unless I add FI
but those numbers don't seem to be very FI friendly.

8psi ant corn fuel will get you close... at least with a turbo, a s/c wouldn't probably get there just do to parasitic drag of the pulley

this is crazy! so many leaks. im waiting for more translations...wish i had more jdm friends :/

Monoblocks were a TRD option.

Yeah, I guess I will leave it N/A after I learned from people.

If there is a reliable plan plan come out, I would consider that. Now I notice that we have to get a stand alone system to work with ECU, which I totally have no idea about it.

100hp/liter, normally aspirated; Not bad

Not bad, but not exactly great or ground breaking either :P

Depends on the price... Which is the only thing that hasn't been leaked.

Lean burns are fine for emissions. The reason why automakers stick with stoich is that it's the most well-balanced. If you run say a 15.5:1, you get better hwy but worse city, and losing some smoothness. The 2012 Mazda3 run 12:1 compression with 14.7:1 air-fuel ratio because stoich ran the best according to them. On a side note, the Mazda3 runs only 12:1 on the Skyactiv G because it's retrofitting a new engine into an older model, and couldn't run a 4:2:1 header that's ideally suited for the engine.

200hp is impressive to me, when you consider that it does that at a lower RPM than a Honda K20 that gets wringed out to 8k.

Aki...you wouldn't happen to be a mechanic with a shop in Milpitas?

Plus it's a Subaru! lol probably doesn't matter to most people but I never thought Subaru would have an NA engine that could hold it's own against anything from Honda. I'm very happy with the engine, turbos don't do much for me. I think people who complain about 200hp don't realize it is about 300lbs lighter than the cars they are comparing it to. It won't be a rocket ship but it won't be wheezing along either.

120 or 140 HP per liter normally aspirated would be better...LOL!

One of my cars has better than 100/L 14 years ago for 23k :shrug:

S2K had 120/L but was more expensive.
